There’s no such thing as bad publicity’ – or so contends a famous adage of the marketing industry.
‘The Bell Curve: Intelligence and Class Structure in America’ by Richard Herrnstein and Charles Murray is perhaps a case in point.
This dry, technical, academic social science treatise, full of statistical analyses, graphs, tables, endnotes and appendices, and totalling almost 900 pages, became an unlikely nonfiction bestseller in the mid-1990s on a wave of almost universally bad publicity in which the work was variously denounced as racist, pseudoscientific, fascist, social Darwinist, eugenicist and sometimes even just plain wrong.
Readers who hurried to the local bookstore eagerly anticipating an incendiary racialist polemic were, however, in for a disappointment.
Indeed, one suspects that, along with ‘The Bible’ and Stephen Hawkins’ ‘A Brief History of Time’, ‘The Bell Curve’ became one of those bestsellers that many people bought, but few managed to finish.
‘The Bell Curve’ thus became, like another book that I have recently reviewed, a book much read about, but rarely actually read – at least in full.
As a result, as with that other book, many myths have emerged regarded the content of ‘The Bell Curve’ that are quite contradicted when one actually takes the time and trouble to read it for oneself.
Ironically, many racialists seem to have taken these leftist critics at their word, enthusiastically citing the work as support for their own views regarding race differences in intelligence.
On the other hand, however, surviving co-author Charles Murray insisted from the outset that the issue of race, and race differences in intelligence, was always peripheral to he and co-author Richard Herrnstein’s primary interest and focus, which was, he claimed, on the supposed emergence of a ‘Cognitive Elite’ in modern America.
Actually, however, both these views seem to be incorrect. While the first section of the book does indeed focus on the supposed emergence of a ‘Cognitive Elite’ in modern America, the overall theme of the book seems to be rather broader.
Thus, the second section of the book focuses on the association between intelligence and various perceived social pathologies, such as unemployment, welfare dependency, illegitimacy, crime and single-parenthood.
To the extent the book has a single overarching theme, one might say that it is a book about the social and economic correlates of intelligence, as measured by IQ tests, in modern America.
Its overall conclusion is that intelligence is indeed a strong predictor of social and economic outcomes for modern Americans – high intelligence with socially desirable outcomes and low intelligence with socially undesirable ones.
On the other hand, however, the topic of race is not quite as peripheral to the book’s themes as sometimes implied by Murray and others.
Thus, it is sometimes claimed only a single chapter dealt with race. Actually, however, two chapters focus on race differences, namely chapters 13 and 14, respectively titled ‘Ethnic Differences in Cognitive Ability’ and ‘Ethnic Inequalities in Relation to IQ’.
In addition, a further two chapters, namely chapters 19 and 20, entitled respectively ‘Affirmative Action in Higher Education’ and ‘Affirmative Action in the Workplace’, deal with the topic of affirmative action, as does the final appendix, entitled ‘The Evolution of Affirmative Action in the Workplace’ – and, although affirmative action has been employed to favour women as well as racial minorities, it is with racial preferences that Herrnstein and Murray are primarily concerned.
However, these chapters represent only 142 of the book’s nearly 900 pages.
Moreover, in much of the remainder of the book, the authors actually explicitly restrict their analysis to white Americans exclusively. They do so precisely because the well documented differences between the races in IQ as well as in many of the social outcomes whose correlation with IQ the book discusses would mean that race would have represented a potential confounding factor that they would otherwise have to take steps to control for.
Herrnstein and Murray therefore took to decision to extend their analysis to race differences near the end of their book, in order to address the question of the extent to which differences in intelligence, which they have already demonstrated to be an important correlate of social and economic outcomes among whites, are also capable of explaining differences in achievement as between races.
If the first controversy of ‘The Bell Curve’ concerns whether it is a book primarily about race and race differences in intelligence, the second controversy is over what exactly the authors concluded with respect to this vexed and contentious issue.
This conclusion, though phrased in sober and restrained terms, is, of course, itself sufficient to place its authors outside the bounds of acceptable opinion in the early-twenty-first century, or indeed in the late-twentieth century when the book was first published, and is sufficient to explain, and, for some, justify, the opprobrium heaped upon the book’s surviving co-author from that day forth.
Intelligence and Social Class
It seems likely that races which evolved on separate continents, in sufficient reproductive isolation from one another to have evolved the obvious (and not so obvious) physiological differences between races that we all observe when we look at the faces, or bodily statures, of people of different races (and that we indirectly observe when we look at the results of different athletic events at the Olympic Games), would also have evolved to differ in psychological traits, including intelligence.
Indeed, it is surely unlikely, on a priori grounds alone, that all different human races have evolved, purely by chance, the exact same level of intelligence.
However, if races differ in intelligence are therefore probable, the case for differences in intelligence as between social classes is positively compelling.
Indeed, on a priori grounds alone, it is inevitable that social classes will come to differ in IQ, if one accepts two premises, namely:
1) Increased intelligence is associated with upward social mobility; and 2) Intelligence is passed down in families.
In other words, if more intelligent people tend, on average, to get higher-paying jobs than those of lower intelligence, and the intelligence of parents is passed on to their offspring, then it is inevitable that the offspring of people with higher-paying jobs will, on average, themselves be of higher intelligence than are the offspring of people with lower paying jobs.
This, of course, follows naturally from the infamoussyllogism formulated by ‘Bell Curve’ co-author Richard Herrnstein way back in the 1970s (p10; p105).
Incidentally, this second premise, namely that intelligence is passed down in families, does not depend on the heritability of IQ in the strict biological sense. After all, even if heritability of intelligence were zero, intelligence could still be passed down in families by environmental factors (e.g. the ‘better’ parenting techniques of high IQ parents, or the superior material conditions in wealthy homes).
The existence of an association between social class and IQ ought, then, to be entirely uncontroversial to anyone who takes any time whatsoever to think about the issue.
If there remains any room for reasoned disagreement, it is only over the direction of causation – namely the question of whether:
1) High intelligence causes upward social mobility; or 2) A privileged upbringing causes higher intelligence.
These two processes are, of course, not mutually exclusive. Indeed, it would seem intuitively probable that both factors would be at work.
Interestingly, however, evidence demonstrates the occurrence only of the former.
Thus, even among siblings from the same family, the sibling with the higher childhood IQ will, on average, achieve higher socioeconomic status as an adult. Likewise, the socioeconomic status a person achieves as an adult correlates more strongly with their own IQ score than it does with the socioeconomic status of their parents or of the household they grew up in (see Straight Talk About Mental Tests: p195).
In other words, children raised in the same home, whether full- or half-siblings or adoptees, are, by the time they reach adulthood, no more similar to one another in IQ than are children of the same degree of biological relatedness brought up in entirelydifferent family homes (see The Nurture Assumption: reviewed here).
However, while the direction of causation may still be disputed by intelligent (if uninformed) laypeople, the existence of an association between intelligence and social class ought not, one might think, be in dispute.
However, in Britain today, in discussions of social mobility, if children from deprived backgrounds are underrepresented, say, at elite universities, then this is almost invariably taken as incontrovertible proof that the system is rigged against them. The fact that children from different socio-economic backgrounds differ in intelligence is almost invariably ignored.
When mention is made of this incontrovertible fact, leftist hysteria typically ensues. Thus, in 2008, psychiatrist Bruce Charlton rightly observed that, in discussion of social mobility:
Meanwhile, when, in the same year, a professor at University College a similar point with regard the admission of working-class students to medical schools, even the then government Health Minister, Ben Bradshaw, saw fit to offer his two cents worth (which were not worth even that), declaring:
“It is extraordinary to equate intellectual ability with social class” (Beckford 2008).
Actually, however, what is truly extraordinary is that any intelligent person, least of all a government minister, would dispute the existence of such a link.
Herrnstein’s syllogism leads to a related paradox – namely that, as environmental conditions are equalized, heritability increases.
Thus, as large differences in the sorts of environmental factors known to affect IQ (e.g. malnutrition) are eliminated, so differences in income have come to increasingly reflect differences in innate ability.
Moreover, the more gifted children from deprived backgrounds who escape their humble origins, then, given the substantial heritability of IQ, the fewer such children will remain among the working-class in subsequent generations.
The result is what Herrnstein and Murray call the ‘Cognitive Stratification’ of society and the emergence of what they call a ‘Cognitive Elite’.
Thus, in feudal society, a man’s social status was determined largely by ‘accident of birth’ (i.e. he inherited the social station of his father).
Women’s status, meanwhile, was determined, in addition, by what we might call ‘accident of marriage’ – and, to a large extent, it still is.
However, today, a person’s social status, at least according to Herrnstein and Murray, is determined primarily, and increasingly, by their level of intelligence.
Of course, people are not allocated to a particular social class by IQ testing itself. Indeed, the use of IQ tests by employers and educators has been largely outlawed on account of its ‘disparate impact‘ (or ‘indirect discrimination’, to use the equivalent British phrase) with regard to race (see below).
However, the skills and abilities increasingly valued at a premium in western society (and, increasingly, many non-western societies as well), mean that, through the operation of the education system and labour market, individuals are effectively sorted by IQ, even without anyone ever actually sitting an IQ test.
In other words, society is becoming increasingly meritocratic – and the form of ostensible ‘merit’ upon which attainment is based is intelligence.
For Herrnstein and Murray, this is a mixed blessing:
“That the brightest are identified has its benefits. That they become so isolated and inbred has its costs” (p25).
However, the correlation between socioeconomic status and intelligence remains imperfect.
For one thing, there are still a few highly remunerated, and very high-status, occupations that rely on skills that are not especially, if at all, related to intelligence. I think here, in particular, of professional sports and the entertainment industry. Thus, leadings actors, pop stars and sports stars are sometimes extremely well-remunerated, and very high-status, but may not be especially intelligent.
More importantly, while highly intelligent people might be, by very definition, the only ones capable of performing cognitively-demanding, and hence highly remunerated, occupations, this is not to say all highly intelligent people are necessarily employed in such occupations.
Thus, whereas all people employed in cognitively-demanding occupations are, almost by definition, of high intelligence, people of all intelligence levels are capable of doing cognitively-undemanding jobs.
Thus, a few people of high intellectual ability remain in low-paid work, whether on account of personality factors (e.g. laziness), mental illness, lack of opportunity or sometimes even by choice (which choice is, of course, itself a reflection of personality factors).
Therefore, the correlation between IQ and occupation is far from perfect.
The sorting of people with respect to their intelligence begins in the education system. However, it continues in the workplace.
Thus, general intelligence, as measured by IQ testing, is, the authors claim, the strongest predictor of occupational performance in virtually every occupation. Moreover, in general, the higher paid and higher status the occupation in question, the stronger the correlation between performance and IQ.
However, Herrnstein and Murray are at pains to emphasize, intelligence is a strong predictor of occupational performance even in apparently cognitively undemanding occupations, and indeed almost always a better predictor of performance than tests of the specific abilities the job involves on a daily basis.
However, in the USA, employers are barred from using testing to select among candidates for a job or for promotion unless they can show the test has ‘manifest relationship’ to the work, and the burden of proof is on the employer to show such a relationship. Otherwise, given their ‘disparate impact’ with regard to race (i.e. the fact that some groups perform worse), the tests in question are deemed indirectly discriminatory and hence unlawful.
Therefore, employers are compelled to test, not general ability, but rather the specific skills required in the job in question, where a ‘manifest relationship’ is easier to demonstrate in court.
However, since even tests of specific abilities almost invariably still tap into the general factor of intelligence, races inevitably score differently even on these tests.
Indeed, because of the ubiquity and predictive power of the g factor, it is almost impossible to design any type of standardized test, whether of specific or general ability or knowledge, in which different racial groups do not perform differently.
However, if some groups outperform others, the American legal system presumes a priori that this reflects test bias rather than differences in ability.
Therefore, although the words “all men are created equal” are not, contrary to popular opinion, part of the US constitution, the Supreme Court has effectively decided, by legal fiat, to decide cases as if they were.
However, just as a law passed by Congress cannot repeal the law of gravity, so a legal presumption that groups are equal in ability cannot make it so.
Thus, the bar on the use of IQ testing by employers has not prevented society in general from being increasingly stratified by intelligence, the precise thing measured by the outlawed tests.
Nevertheless, Herrnstein and Murray estimate that the effective bar on the use of IQ testing makes this process less efficient, and cost the economy somewhere between 80 billion to 13 billion dollars in 1980 alone (p85).
Conscientiousness and Career Success
I am skeptical of Herrnstein and Murray’s conclusion that IQ is the best predictor of academic and career success. I suspect hard work, not to mention a willingness to toady, toe the line, and obey orders, is at least as important in even the most cognitively-demanding careers, as well as in schoolwork and academic advancement.
Perhaps the reason these factors have not (yet) been found to be as highly correlated with earnings as is IQ is that we have not yet developed a way of measuring these aspects of personality as accurately as we can measure a person’s intelligence through an IQ test.
For example, the closest psychometricians have come to measuring capacity for hard work is the personality factor known as ‘conscientiousness’, one of the Big Five factors of personality revealed by psychometric testing.
Conscientiousness does indeed correlate with success in education and work (e.g. Barrick & Mount 1991). However, the correlation is weaker than that between IQ and success in education and at work.
Thus, to assess conscientiousness, questionnaires ask respondents whether they ‘see themselves as organized’, ‘as able to follow an objective through to completion’, ‘as a reliable worker’, etc.
This would be the equivalent of an IQ test that, instead of directly testing a person’s ability to recognize patterns or manipulate shapes by having them do just this, simply asked respondents how good they perceived themselves as being at recognizing patterns, or manipulating shapes.
Obviously, this would be a less accurate measure of intelligence than a normal IQ test. After all, some people lie, some are falsely modest and some are genuinely deluded.
Indeed, according to the Dunning Kruger effect, it is those most lacking in ability who most overestimate their abilities – precisely because they lack the ability to accurately assess their ability (Kruger & Dunning 1999).
In an IQ test, on the other hand, one can sometimes pretend to be dumber than one is, by deliberately getting questions wrong that one knows the answer to.
However, it is not usually possible to pretend to be smarter than one is by getting more questions right simply because one would not know what are the right answers.
‘Affirmative Action’ and Test Bias
In chapters nineteen and twenty, respectively entitled ‘Affirmative Action in Higher Education’ and ‘Affirmative Action in the Workplace’, the authors discuss so-called ‘affirmative action’, an American euphemism for systematic and overt discrimination against white males.
It is well-documented that, in the United States, blacks, on average, earn less than white Americans. On the other hand, it is less well-documented that whites, on average, earn less than people of Indian, Chinese and Jewish ancestry.
Indeed, according to Herrnstein and Murray, the difference in earnings between whites and blacks, not only disappears after controlling for differences in IQ, but is actually partially reversed. Thus, blacks are actually somewhat overrepresented in professional and white-collar occupations as compared to whites of equivalent IQ.
This remarkable finding Herrnstein and Murray attribute to the effects of affirmative action programmes, as black Americans are appointed and promoted beyond what their ability merits because through discrimination.
Interestingly, however, this contradicts what the authors wrote in an earlier chapter, where they addressed the question oftestbias (pp280-286).
There, they concluded that testing was not biased against African-Americans, because, among other reasons, IQ tests were equally predictive of real-world outcomes (e.g. in education and employment) for both blacks and whites, and blacks do not perform any better in the workplace or in education than their IQ scores predict.
This is, one might argue, not wholly convincing evidence that IQ tests are not biased against blacks. It might simply suggest that society at large, including the education system and the workplace, is just as biased against blacks as are the hated IQ tests. This is, of course, precisely what we are often told by the television, media and political commentators who insist that America is a racist society, in which such mysterious forces as ‘systemic racism’ and ‘white privilege’ are pervasive.
In fact, the authors acknowledge this objection, conceding:
“The tests may be biased against disadvantaged groups, but the traces of bias are invisible because the bias permeates all areas of the group’s performance. Accordingly, it would be as useless to look for evidence of test bias as it would be for Einstein’s imaginary person traveling near the speed of light to try to determine whether time has slowed. Einstein’s traveler has no clock that exists independent of his space-time context. In assessing test bias, we would have no test or criterion measure that exists independent of this culture and its history. This form of bias would pervade everything” (p285).
Herrnstein and Murray ultimately reject this conclusion on the grounds that it is simply implausible to assume that:
“[So] many of the performance yardsticks in the society at large are not only biased, they are all so similar in the degree to which they distort the truth-in every occupation, every type of educational institution, every achievement measure, every performance measure-that no differential distortion is picked up by the data” (p285).
In fact, however, Nicholas Mackintosh identifies one area where IQ tests do indeed under-predict black performance, namely with regard to so-called adaptive behaviours – i.e. the ability to cope with day-to-day life (e.g. feed, dress, clean, interact with others in a ‘normal’ manner).
Blacks with low IQs are generally much more functional in these respects than whites or Asians with equivalent low IQs (see IQ and Human Intelligence: p356-7).
Yet Herrnstein and Murray seem to have inadvertently, and evidently without realizing it, identified yet another sphere where standardized testing does indeed under-predict real-world outcomes for blacks.
Thus, if indeed, as Herrnstein and Murray claim, blacks are somewhat overrepresented among professional and white-collar occupations relative to their IQs, this suggests that blacks do indeed do better in real-world outcomes than their test results would predict and, while Herrnstein and Murray attribute this to the effect of discrimination against whites, it could instead surely be interpreted as evidence that the tests are biased against blacks.
What, then, are the policy implications that Herrnstein and Murray draw from the findings that they report?
In The Blank Slate: The Modern Denial of Human Nature, cognitive science, linguist and popular science writer Steven Pinker popularizes the notion that recognizing the existence of innate differences between individuals and groups in traits such as intelligence does not necessarily lead to ‘right-wing’ political implications.
Thus, a leftist might accept the existence of innate differences in ability, but conclude that, far from justifying inequality, this is all the more reason to compensate the, if you like, ‘cognitively disadvantaged’ for their innate deficiencies, differences which are, being innate, hardly something for which they can legitimately be blamed.
Herrnstein and Murray reject this conclusion, but acknowledge it is compatible with their data. Thus, in an afterword to later editions, Murray writes:
“If intelligence plays an important role in determining how well one does in life, and intelligence is conferred on a person through a combination of genetic and environmental factors over which that person has no control, the most obvious political implication is that we need a Rawlsian egalitarian state, compensating the less advantaged for the unfair allocation of intellectual gifts” (p554).
Interestingly, Pinker’s notion of a ‘hereditarian left’, and the related concept of ‘Bell Curve liberals’, is not entirely imaginary. On the contrary, it used to be quite mainstream.
Thus, it was the radical leftist post-war Labour government that imposed the tripartite system on schools in the UK in 1945, which involved allocating pupils to different schools on the basis of their performance in what was then called the 11-plus exam, conducted at with children at age eleven, which tested both ability and acquired knowledge. This was thought by leftists to be a fair system that would enable bright, able youngsters from deprived and disadvantaged working-class backgrounds to achieve their full potential.
However, a distinction must be made here. While it is possible to justify economic redistributive policies on Rawlsian grounds, it is not possible to justify affirmative action.
Thus, one might well reasonably contend that the ‘cognitively disadvantaged’ should be compensated for their innate deficiencies through economic redistribution. Indeed, to some extent, most Western polities already do this, by providing welfare payments and state-funded, or state-subsidized, care to those whose cognitive impairment is such as to qualify as a disability and hence render them incapable of looking after or providing for themselves.
However, we are unlikely to believe that such persons should be given entry to medical school such that they are one day liable to be responsible for performing heart surgery on us or diagnosing our medical conditions.
In short, socialist redistribution is defensible – but affirmative action is definitely not!
Both were greeted with similar indignant moralistic outrage by many social scientists, who even employed similar pejorative soundbites (‘genetic determinism’, ‘reductionism’, ‘biology as destiny’), in condemning the two books. Moreover, in both cases, the academic uproar even spilled over into a mainstream media ‘moral panic’, with pieces appearing the popular press attacking the two books.
Yet, in both cases, the controversy focused almost exclusively on just a small part of each book – the single chapter in ‘Sociobiology: The New Synthesis’ focusing on humans and the few chapters in ‘The Bell Curve’ discussing race.
In truth, however, both books were massive tomes of which these sections represented only a small part.
Indeed, due to their size, one suspects most critics never actually read the books in full for themselves, including, it seemed, most of those nevertheless taking it upon themselves to write critiques. This is what led to the massive disconnect between what most people thought the books said, and their actual content.
As I have written in my review of that latter work, the scale of Wilson’s ambition can hardly be exaggerated. He sought to provide a new foundation for the whole field of animal behaviour, then, almost as an afterthought, sought to extend this ‘New Synthesis’ to human behaviour as well, which meant providing a new foundation, not for a single subfield within biology, but for several whole disciplines (psychology, sociology, economics and cultural anthropology) that were formerly almost unconnected to biology. Then, in a few provocative sentences, he even sought to provide a new foundation for moral philosophy, and perhaps epistemology too.
‘Sociobiology: The New Synthesis’ was, then, inevitably and of necessity, a long book. Indeed, given that his musings regarding the human species were largely (but not wholly) restricted to a single chapter, one could even make a case that it was too short – and it is no accident that Wilson subsequently extended his writings with regard to the human species to a book length manuscript.
Yet, while Sociobiology was of necessity a long book, ‘The Bell Curve: Intelligence and Class Structure in America’ is, for me, unnecessarily overlong.
After all, Herrnstein and Murray’s thesis was actually quite simple – namely that cognitive ability, as captured by IQ testing, is a major correlate of many important social outcomes in modern America.
Yet they reiterate this point, for different social outcomes, again and again, chapter after chapter, repeatedly.
In my view, Herrnstein and Murray’s conclusion would have been more effectively transmitted to the audience they presumably sought to reach had they been more succinct in their writing style and presentation of their data.
Had that been the case then perhaps rather more of the many people who bought the book, and helped make it into an unlikely nonfiction bestseller in 1994, might actually have managed to read it – and perhaps even been persuaded by its thesis.
 For example, Francis Wheen, a professional damned fool and columnist for the Guardian newspaper (which two occupations seem to be largely interchangeable) claimed that:
“The Bell Curve (1994), runs to more than 800 pages but can be summarised in a few sentences. Black people are more stupid than white people: always have been, always will be. This is why they have less economic and social success. Since the fault lies in their genes, they are doomed to be at the bottom of the heap now and forever” (Wheen 2000).
In making this claim, Wheen clearly demonstrates that he has read few if any of those 800 pages to which he refers.
 For example, some of those accused of serious crimes have been accused of deliberately getting questions wrong on IQ tests in order to qualify as mentally subnormal when before the courts for sentencing in order to be granted mitigation of sentence on this ground, or, more specifically, in order to evade the death penalty.
 This may be because whites or Asians with such low IQs are more likely to have such impaired cognitive abilities because of underlying conditions (e.g chromosomal abnormalities, brain damage) that handicap them over and above the deficit reflected in IQ score alone. On the other hand, blacks with similarly low IQs are still within the normal range for their own race. Therefore, rather than suffering from, say, a chromosomal abnormality or brain damage, they are relatively more likely to simply be at the tail-end of the normal range of IQs within their group, and hence normal in other respects.
 The term Rawlsian is a reference to political theorist John Rawles version of social contract theory, whereby he poses the hypothetical question as to what arrangement of political, social and economic affairs humans would favour if placed in what he called ‘the original position’, where they would be unaware of, not only their own race, sex and position in to the socio-economic hierarchy, but also, most important for our purposes, their own level of innate ability. This Rawles referred to as ‘veil of ignorance’.
 The tripartite system did indeed enable many working-class children to achieve a much higher economic status than their parents, although this was partly due to the expansion of the middle-class sector of the economy over the same time-period. It was also later Labour administrations who largely abolished the 11-plus system, not least because, unsurprisingly given the heritability of intelligence and personality, children from middle-class backgrounds tended to do better on it than did children from working-class backgrounds.
“Baker’s treatise, compendious and ponderous, is possible the last major statement of traditional race science written in English” (The Race Gallery: p61).
Inevitably for a scientific work first published over forty years ago, ‘Race’ is dated. In particular, the DNA revolution in population genetics has revolutionized our understanding of the genetic differences and relatedness between different human populations.
Lacking access to such data, Baker had only indirect phenotypic evidence (i.e. the morphological similarities and differences between different peoples), as well as historical and geographic evidence, with which to infer such relationships and hence construct his racial phylogeny and taxonomy.
Phenotypic similarity is obviously a less reliable method of determining the relatedness between groups than is provided by genome analysis, since there is always the problem of distinguishing homology from analogy and hence misinterpreting a trait that has independently evolved in different populations as evidence of relatedness.
However, I found only one case of genetic studies decisively contradicting Baker’s conclusions. Thus, whereas Baker classes the Ainu People of Japan as “Europid” (p158; p173; p424; p625), recent genetic studies suggest that the Ainu have little or no genetic affinities to Caucasoid populations and are most closely related to other East Asians.
On the other hand, however, Baker’s omission of genetic data means that, unusually for a scientific work, in the material he does cover, ‘Race’ scarcely seems to have dated at all. This is because the primary focus of Baker’s book – namely, morphological differences between races – is a field of study that has become politically suspect and in which new research has now all but ceased.
Thus, Baker’s ‘Race’ can be viewed as the final summation of the accumulated findings of the ‘old-style’ physical anthropology of the nineteenth and early-twentieth centuries, published at the very moment this intellectual tradition was in its death throes.
Baker’s ‘Race’ is indeed a magnum opus. Unfortunately, however, at over 600 pages, embarking on reading ‘Race’ might seem almost like a lifetime’s work in and of itself.
Not only is it a very long book, but, in addition, much of the material, particularly on morphological race differences and their measurement, is highly technical, and will be readily intelligible only to the dwindling band of biological anthropologists who, in the genomic age, still study such things.
This inaccessibility is exacerbated by the fact that Baker does not use endnotes, except for his references, and only very occasionally uses footnotes. Instead, he includes even technical and peripheral material in the main body of his text, but indicates that material is technical or peripheral by printing it in a smaller font-size.
Baker’s terminology is also confusing. He prefers the ‘-id’ suffix to the more familiar ‘-oid’ and ‘-ic’ (e.g. ‘Negrid‘ and ‘Nordid‘ rather than ‘Negroid’ and ‘Nordic‘) and eschews the familiar terms ‘Caucasian’ or ‘Caucasoid’, on the grounds that:
“The inhabitants of the Caucasus region are very diverse and very few of them are typical of any large section of Europids” (p205).
However, his own preferred alternative term, ‘Europid’, is arguably equally misleading as it contributes to the already common conflation of Caucasian with white European, even though, as Baker is at pains to emphasize elsewhere in his treatise, populations from the Middle East, North Africa and even the Indian subcontinent are also ‘Europid’ (i.e. Caucasoid) in Baker’s judgement.
In contrast, the term ‘Caucasoid’, or even ‘Caucasian’, causes little confusion in my experience, since it is today generally understood as a racial term and not as a geographical reference to the Caucasus region.
Certainly, the term ‘Caucasoid’ makes little etymological sense. However, this is also true of a lot of words which we nevertheless continue to make use of. Indeed, since all words change in meaning over time, the original meaning of a word is almost invariably different to its current accepted usage.
Yet we continue to use these words so as to make ourselves intelligible to others, the only alternative being to invent an entirely new language all of our own which only we would be capable of understanding.
Unfortunately, however, too many racial theorists, Baker included, have insisted on creating entirely new racial terms of their own coinage, or sometimes new entire lexicons, which, not only causes confusion among readers, but also leads the casual reader to underestimate the actual degree of substantive agreement between different authors, who, though they use different terms, often agree regarding both the identity of, and relationships between, the major racial groupings.
Another problem is the book’s excessive historical focus.
Judging the book by its contents page, one might imagine that Baker’s discussion of the history of racial thought is confined to the first section of the book, titled “The Historical Background” and comprising four chapters that total just over fifty pages.
However, Baker acknowledges in the opening page of his preface that:
“Throughout this book, what might be called the historical method has been adopted as a matter of deliberate policy” (p3).
Thus, in the remainder of the book, Baker continues to adopt an historical perspective, briefly charting the history behind the discovery of each concept, archaeological discovery, race difference or method of measuring race differences that he introduces.
In short, it seems that Baker is not content with writing about science; he wants to write history of science too.
A case in point is Chapter Eight, which, despite its title (“Some Evolutionary and Taxonomic Theories”), actually contains very little on modern taxonomic or evolutionary theory, or even what would pass for ‘modern’ when Baker wrote the book over forty years ago.
Instead, the greater part of the chapter is devoted to tracing the history of two theories that were, even at the time Baker was writing, already wholly obsolete and discredited (namely, recapitulation theory and orthogenesis).
Let me be clear, Baker himself certainly agrees that these theories are obsolete and discredited, as this is his conclusion at the end of the respective sections devoted to discussion of these theories in his chapter on “Evolutionary and Taxonomic Theories”.
However, this only begs the question as to why Baker chooses to devote so much space in this chapter to discussing these theories in the first place, given that both theories are discredited and also of only peripheral relevance to his primary subject-matter, namely the biology of race.
Anyone not interested in these topics, or in history of science more generally, is well advised to skip the majority of this chapter.
“The Historical Background”
Readers not interested in the history of science, and concerned only with contemporary state-of-the-art science (or at least the closest an author writing in 1974 can get to modern state-of-the-art science) may also be tempted to skip over the whole first section of the book, entitled, as I have said, “The Historical Background”, and comprised of four chapters or, in total, just over fifty pages.
These days, when authoring a book on the biology of race, it seems to have become almost de rigueur to include an opening chapter, or chapters, tracing the history of race science, and especially its political misuse during nineteenth and early twentieth-centuries (e.g. under the Nazis).
The usual reason for including these chapters is for the author or authors to thereby disassociate themselves from the earlier supposed ‘misuse’ of race science for nefarious political purposes, and emphasize how their own approach is, of course, infinitely more scientific and objective than that of their sometimes less than illustrious intellectual forebears.
However, Baker’s discussion of “The Historical Background” is rather different, and refreshingly short on disclaimers, moralistic grandstanding and benefit-of-hindsight condemnations that one usually finds in such potted histories.
Instead, Baker strives to give all views, howsoever provocative, a fair hearing in as objective and sober a tone as possible.
Only Lothrop Stoddard, strangely, is dismissed altogether. The latter is, for Baker, an “obviously unimportant” thinker, whose book “contains nothing profound or genuinely original” (p58-9).
Yet this is perhaps unfair. Whatever the demerits of Stoddard’s racial taxonomy (“oversimplified to the point of crudity,” according to Baker: p58), Stoddard’s geopolitical and demographic predictions have proven prescient.
Overall, Baker draws two general conclusions regarding the history of racial thought in the nineteenth and early twentieth century.
First, he observes how few of the racialist authors whom he discusses were anti-Semitic. Thus, Baker reports:
The rest of the authors whom he discusses evince, according to Baker, “little or no interest in the Jewishproblem”, the only exception being Friedrich Nietzsche, who is “primarily an anti-egalitarian, but [who] did not proclaim the inequality of ethnic taxa”, and who, in his comments regarding the Jewish people, or at least those quoted by Baker, is positively gushing in his praise.
Yet anti-Semitism often goes hand-in-hand with philo-Semitism. Thus, both Nietzsche and Count de Gobineau indeed wrote passages that, at least when quoted in isolation, seem highly complementary regarding the Jewish people. However, it is well to bear in mind that Hitler did as well, the latter writing in Mein Kampf:
Baker’s second general observation is similarly curious, namely that:
“None of the authors mentioned in these chapters claims superiority for the whole of the Europid race: it is only a subrace, or else a section of the Europid race not clearly defined in terms of physical anthropology, that is favoured” (p59).
However, this focus on the alleged superiority of certain European subraces rather than Caucasians as a whole likely reflects the fact that, during the time period in which these works were written, European peoples and nations were largely in competition and conflict with other European peoples and nations.
Only in European overseas colonies were Europeans in contact and conflict with non-European races, and, even here, the main obstacle to imperial expansion was, not so much the opposition of the often primitive non-European races whom the Europeans sought to colonize, but rather that of rival colonizers from other European nations.
Therefore, it was the relative superiority of different European populations which was naturally of most concern to Europeans during this time period.
In contrast, the superiority of the Caucasian race as a whole was of comparably little interest, if only because it was something that these writers already took very much for granted, and hence hardly worth wasting ink or typeface over.
The Rise of Racial Egalitarianism
There are two curious limitations that Baker imposes on his historical survey of racial thought. First, at the beginning of Chapter Three (‘From Gobineau to Houston Chamberlain’), he announces:
“The present chapter and the next [namely, those chapters dealing with the history of racial thinking from the mid-nineteenth century up until the early-twentieth century] differ from the two preceding ones… in the more limited scope. It is are concerned only with the growth of ideas that favoured belief in the inequality of ethnic taxa or are supposed—rightly or wrongly—to have favoured this belief” (p33).
Given that I have already criticised ‘Race’ as overlong, and as having an excessive historical focus, I might be expected to welcome this restriction. However, Baker provides no rationale for this self-imposed restriction.
Certainly, it is rare, and enlightening, to read balanced, even sympathetic, accounts of the writings of such infamous racialist thinkers as Gobineau, Galton and Chamberlain, whose racial views are today usually dismissed as so preposterous as hardly to merit serious consideration. Moreover, in the current political climate, such material even acquires a certain ‘allure of the forbidden’.
However, thinkers championing racial egalitarianism have surely proven more influential, at least in the medium-term. Yet such enormously influential thinkers as Franz Boas and Ashley Montagu pass entirely unmentioned in Baker’s account.
Moreover, the intellectual antecedents of the Nazism have already been extensively explored by historians. In contrast, however, the rise of the dogma of racial equality has passed largely unexamined, perhaps because to examine its origins is to expose the weakness of its scientific basis and its fundamentally political origins.
The second restriction that Baker imposes upon his history is that he concludes it, prematurely, in 1928. He justifies closing his survey in this year on the grounds that this date supposedly:
“Marks the close of the period in which both sides in the ethnic controversy were free to put forward their views, and authors who wished to do so could give objective accounts of the evidence pointing in each direction” (p61).
Yet this cannot be entirely true, for, if it were, then Baker’s own book could never have been published – unless, of course, Baker regards his own work as something other than an “objective account of the evidence pointing in each direction”, which seems doubtful.
Certainly, the influence of what is now called political correctness is to be deplored for impact on science, university appointments, the allocation of research funds and the publishing industry. However, there has surely been no abrupt watershed but rather a gradual closing of the western mind over time.
Thus, it is notable that other writers have cited dates a little later than that quoted by Baker, often coinciding with the defeat of Nazi Germany and exposure of the Nazi genocide, or sometimes the defeat of segregation in the American South.
Indeed, not only was this process gradual, it has also proceeded apace in the years since Baker’s ‘Race’ first came off the presses, such that today such a book would surely never would have been published in the first place, certainly not by as prestigious a publisher as Oxford University Press (who, surely not uncoincidently, soon gave up the copyright).
Moreover, Baker is surely wrong to claim that it is impossible:
“To follow the general course of controversy on the ethnic problem, because, for the reason just stated [i.e. the inability of authors of both sides to publicise their views], there has been no general controversy on the subject” (p61).
Having dealt in his first section with what he calls “The Historical Background”, Baker next turns to what he calls “The Biological Background”. He begins by declaring, rightly, that:
“Racial problems cannot be understood by anyone whose interests and field of knowledge stop short at the limit of purely human affairs” (p3).
This is surely true, not just of race, but of all issues in human biology, psychology, sociology, anthropology and political science, as the recent rise of sociobiology and evolutionary psychology attests. Indeed, Baker even coins a memorable and quotable aphorism to this effect, when he declares:
Certainly, he is right to emphasise that differences among human populations are analogous to those found among other species. Thus, his discussion of racial differences among our primate cousins are of interest, but also somewhat out-of-date.
However, his intricate and fully illustrated nine-page description of race differences among the different subspecies of crested newt stretched the patience of this reader (p101-109).
Are Humans a Single Species?
Whereas Baker’s seventh chapter (“The Meaning of Race”) discusses the race concept, the preceding two chapters deal with the taxonomic class immediately above that of race, namely ‘species’.
For sexually-reproducing organisms, ‘species’ is usually defined as the largest group of organisms capable of breeding with one another and producing fertile offspring in the wild.
However, as Baker explains, things are not quite so simple.
Moreover, in respect of extinct species, it is often impossible to know for certain whether two ostensible ‘species’ interbred with one another (p72-3). Therefore, in practice, the fossils of extinct organisms are assigned to either the same or different species on morphological criteria alone.
On purely morphological criteria, Baker questions humanity’s status as a single species:
“Even typical Nordids and typical Alpinids, both regarded as subraces of a single race (subspecies), the Europid, are very much more different from one another in morphological characters—for instance in the shape of the skull—than many species of animals that never interbreed with one another in nature, though their territories overlap” (p97).
These two ostensible species (or subspecies), both found in the UK, do not interbreed with one another, but each does interbreed with intermediaries that, in turn, interbreed with the other, such that there is some indirect gene-flow between them. Interestingly, the species ranges of the different intermediaries form a literal ring around the Arctic, such that genes will travel around the Artic before passing from lesser black backed gull to herring gull or vice versa (p76-79).
Indeed, even the ability to produce fertile offspring is a matter of degree. Thus, some pairings produce fertile offspring only rarely.
For example, often, Baker reports, “sterility affects [only] the heterogametic sex [i.e. the sex with two different sex chromosomes]” (p95). Thus, in mammals, sterility is more likely to affect male offspring. Indeed, this pattern is so common that it even has its own name, being known as Haldane’s Rule, after the famous Marxist-biologist JBS Haldane who first noted this pattern.
Other times, Baker suggests, interfertility may depend on the sex of the respective parents. For example, Baker suggests that, whereas sheep may sometimes successfully reproduce with he-goats, rams may be unable to successfully reproduce with she-goats (p95).
Moreover, the fertility of offspring is itself a matter of degree. Thus, Baker reports, some hybrid offspring are not interfertile with one another, but can reproduce with one or other of the parental stocks. Elsewhere, the first generation of hybrids are interfertile but not subsequent generations (p94).
Indeed, though it was long thought impossible, it has recently been confirmed that, albeit only very rarely, even mules and hinnies can successfully reproduce, despite donkeys and horses, the two parental stocks, having, like goats and sheep, a different number of chromosomes (Rong et al 1985; Kay 2002).
Thus, Baker concludes:
“There is no proof that hybridity among human beings is invariably eugenesic, for many of the possible crosses have not been made, or if they have their outcome does not appear to have been recorded. It is probable on inductive grounds that such marraiges would not be infertile, but it is questionable whether the hybridity would necessarily be eugenesic. For instance, statistical study might reveal a preponderance of female offpsring” (p97-8).
Is there then any evidence of reduced fertility among mixed-race couples? Not a great deal.
However, this is a simple reflection of the differences in average stature of between whites and Asians, with smaller-framed Asian women having difficulty birthing larger half-white offspring. Thus, the same study also found that white women birthing offspring fathered by Asian men actually have lower rates of caesarean delivery than did women bearing offspring fathered by men of the same race as themselves (Stanford University Medical Center 2008).
This lack of selection against either European-derived (or African-derived) genes in African-Americans suggests that discordant genes did not result in reduced fitness among African-Americans.
Humans – A Domesticated Species?
A final complication in defining species is that some species of nonhuman animal, wildly recognised as separate species because they do not interbreed in the wild, nevertheless have been known to successfully interbreed in captivity.
A famous example are lions and tigers. While they have never been known to interbreed in the wild, if only because they rarely if ever encounter one another, they have interbred in captivity, sometimes even producing fertile offspring in the form of so-called ligers and tigons.
This is, for Baker, of especial relevance to question of human races since, according to Baker, we ourselves are a domesticated species. Thus, he approvingly quotes Blumenbach’s claim that:
“Man is ‘of all living beings the most domesticated’” (p95).
Thus, with regard to the question of whether humans represent a single species, Baker reaches the following controversial conclusion:
“The facts of human hybridity do not prove that all human races are to be regarded as belonging to a single ‘species’. The whole idea of species is vague because the word is used with such different meanings, none of which is of universal application. When it is used in the genetical sense [i.e. the criterion of interfertility] some significance can be attached to it, in so far as it applies to animals existing in natural conditions… but it does not appear to be applicable to human beings, who live under the most extreme conditions of domestication” (p98).
Thus, Baker goes so far as to question whether:
“Any two kinds of animals, differing from one another so markedly in morphological characters (and in odour) as, for instance, the Europid and Sanid…, and living under natural conditions, would accept one another as sexual partners” (p97).
On the contrary, they were separated from one another by the very geographic obstacles (oceans, deserts, mountain-ranges) that reproductively isolated them from one another and hence permitted their evolution into distinct races.
Thus, Northern Europeans surely never mated with sub-Saharan Africans for the simple reason that the former were confined to Northern Europe and surrounding areas while the latter were largely confined to sub-Saharan Africa, such that they are unlikely ever to have interacted.
Only with the invention of technologies facilitating long-distance travel (e.g. ocean-going ships, aeroplanes) would this change.
Ultimately then, the question of whether the human race is a single species is a purely semantic dispute. It depends how one defines the word ‘species’.
Likewise, whether human races can be said to exist ultimately depends on one’s definition of the word ‘race’.
Using the word ‘race’ interchangeably with that of ‘subspecies’, Baker provides no succinct definition. Instead, he simply explains:
“If two populations [within a species] are so distinct that one can generally tell from which region a specimen was obtained, it is usual to give separate names to the two races” (p99).
Neither does he provide a neat definition of any particular race. On the contrary, he is explicit in emphasizing:
“The definition of any particular race must be inductive in the sense that it gives a general impression of the distinctive characters, without professing to be applicable in detail to every individual” (p99).
Is Race Real?
At the conclusion of his chapter on “Hybridity and The Species Question”, Baker seems to reach what was, even in 1974, an incendiary conclusion – namely that, whether using morphological criteria or the criterion of interfertility, it is not possible to conclusively prove that all extant human populations belong to a single species (see above).
Nevertheless, in the remainder of the book, Baker proceeds on the assumption that differences among human groups are indeed subspecific (i.e. racial) in nature and that we do indeed form a single species.
“Subraces and even races sometimes hybridise where they meet, but this almost goes without saying: for if sexual revulsion against intersubracial or interracial marriages were complete, one set of genes would have no chance of intermingling with the other, and the ethnic taxa would be species by the commonly accepted definition. It cannot be too strongly stressed that intersubracial and interracial hybridization is so far from indicating the unreality of subraces and races, that it is actually a sine qua non of the reality of these ethnic taxa” (p12).
Some people seem to think that, since races tend to blend into one another and hence have blurred boundaries (i.e. what biologists refer to as clinal variation), they do not really exist. Yet Baker objects:
“In other matters, no one questions the reality of categories between which intermediaries exist. There is every graduation, for instance, between green and blue, but no one denies these words should be used” (p100).
However, this is perhaps an unfortunate example, since, as psychologists and physicists agree, colours, as such, do not exist.
Instead, the spectrum of light varies continuously. Distinct colours are imposed on this continuous variation only by the human brain and visual system.
Using colour as an analogy for race is also potentially confusing because colour is already often conflated with race. Thus, races are referred to by their ostensible colours (e.g. ‘blacks’, ‘whites’, ‘browns’ etc.) and the very word ‘colour’ is sometimes even used as a synonym, or perhaps euphemism, for race, even though, as Baker is at pains to emphasize, races differ in far more than skin colour.
Using colour as an analogy for race differences is only likely to exacerbate this confusion.
Yet Baker’s other examples are similarly problematic. Thus, he writes:
“The existence of youths and human hermaphrodites does not cause anyone to disallow the use of the words, ‘boy’, ‘man’ and ‘woman’” (p100).
“We tend to use crude labels in everyday life with the realization that they are fuzzy and subjective. I doubt anyone thinks that terms such as ‘short’, ‘medium’ and ‘tall’ refer to discrete groups, or that humanity only comes in three values of height” (Relethford 2009: p21).
In short, we often resort to vague and impressionistic language in everyday conversation. However, for scientific purposes, we must surely try, wherever possible, to be more precise.
“Is social class… a useless concept because of its cline-like tendency to merge smoothly from case to case across the distribution, of because its discrete categories are determined by researchers according to their research purposes and are definitely not ‘pure’” (Race and Crime: A Biosocial Analysis: p6).
However, the same leftist social scientists who insist the race concept is an unscientific social construction, nevertheless continue to employ the concept of social class almost as if it were entirely unproblematic.
However, the objection that races do not exist because races are not discrete categories, but rather have blurred boundaries, is not entirely fallacious.
After all, sometimes intermediaries can be so common that they can no longer be said to be intermediaries at all and all that can be said to exist is continuous clinal variation, such that wherever one chose to draw the boundary between one race and another would be entirely arbitrary.
With increased migration and intermarriage, we may fast be approaching this point.
Remarkably, Baker even manages to anticipate certain erroneous objections to the race concept that had not, to my knowledge, even been formulated at the time of his writing, perhaps because they are so obviously fallacious to anyone without an a priori political commitment to the denying the validity of the race concept.
Certainly, he is at pains to emphasise that, among humans, differences between racial groups go far beyond skin colour. Indeed, he observes, one has only to look at an African albino to realize as much:
“An albino…Negrid who is fairer than any non-albino European, [yet] appears even more unlike a European than a normal…Negrid” (p160).
For Baker, these are what he calls “secondary characters” that cannot be used for the purposes of racial classification because they are not present among all members of any group, but differ only in their relative prevalence (p186).
It is therefore irrelevant from the perspective of cladistic taxonomy, whereby organisms are grouped, not on the basis of shared traits as such, but rather of shared ancestry. From the perspective of cladistic taxonomy, shared traits are relevant only to the extent they are (interpreted as) evidence of shared ancestry.
“One must always be on the lookout for the possibility of independent mutation wherever two apparently unrelated taxa resemble one another by the fact that some individuals in both groups reveal the presence of the same gene” (p189).
In evolutionary biology, this is referred to as distinguishing analogy from homology.
“There are two groups of people [i.e. races] with the conbination of dark skin and frizzy hair—sub-Saharan Africans and Melanesians. The latter have often been called ‘Oceanic Negroes,’ implying a special relationship with Africans. The blood-group data, however, show that they are about as different from Africans as they could be” (Race: The Reality of Human Differences: p134).
But Diamond’s proposed classification is even more preposterous than these early pre-Darwinian non-cladistic taxonomic schemes, since he proposes to classify races on the basis of a single trait in isolation, the trait in question (either lactose tolerance or the sickle-cell gene) being chosen either arbitrarily or, more likely, to illustrate the point that Diamond is attempting to make.
Yet even pre-Darwinian taxonomies proposed to classify species, not on the basis of a single trait, but rather on the basis of a whole suit of traits that intercorrelate together.
In short, Diamond proposes to classify races on the basis of a single character that has evolved independently in distantly related populations, instead of a whole suite of inter-correlated traits indicative of common ancestry.
Interestingly, a similar error may underlie an even more frequently cited paper by Marxist-geneticist Richard Lewontin, which argued the vast majority of genetic variation was within-group rather than between-group – since Lewontin, like Diamond, also relied on ‘secondary characters’ such as blood-groups to derive his estimates (Lewontin 1972).
The reason for the recurrence of this error, Baker explains, is that:
“Each of the differences that enable one to distinguish all the most typical individuals of any one taxon from those of another is due, as a general rule, to the action of polygenes, that is to say, to the action of numerous genes, having small cumulative effects” (p190).
Therefore, this leads to the “unfortunate paradox” whereby:
“The better the evidence of relationship or distinction between ethnic taxa, the less susceptible are the facts to genetic analysis” (p190).
As a consequence, Baker laments:
“Attention is focussed today on those ‘secondary differences’… that can be studied singly and occur in most ethnic taxa, though in different proportions in different taxa… The study of these genes… has naturally led, from its very nature, to a tendency to minimise or even disregard the extent to which the ethnic taxa of man do actually differ from one another” (p534).
“From the perspective of taste-deficiency the Europids are much closer to the chimpanzee than to the Sinids and Paiwan people; yet no one would claim that this resemblance gives a true representation of relationship” (p188).
However, applying the logic of Diamond’s article, we would be perfectly justified and within our rights to use this similarity in taste deficiency in order to classify Caucasians as a sub-species of chimpanzee!
The third section of Baker’s book, “Studies of Selected Human Groups”, focusses on the traditional subject-matter of physical anthropology – i.e. morphological differences between human groups.
Baker describes the physiological differences between races in painstaking technical detail. These parts of the book makes for an especially difficult read, as Baker carefully elucidates both how anthropologists measure morphological differences, and the nature and extent of the various physiological differences between the races discussed revealed by these methods.
Yet, curiously, although many of his measures are quantitative in nature, Baker rarely discusses whether differences are statistically significant. Yet without statistical analysis, all of Baker’s reports of quantitative measurements of differences in the shapes and sizes of the skulls and body parts of people of different races represent little more than subjective impressions.
This is especially problematic in his discussion of so-called ‘subraces’ (subdivisions within the major continental races, such as Nordics and the Meditaranean race, both supposed subdivisions within the Caucasiod race), where differences could easily be dismissed as, if not wholly illusory, then at least as clinal in nature and as not always breeding true.
Yet nowhere in his defence of the reality of subracial differences does Baker cite statistics. Instead, his argument is wholly subjective and qualitative in nature:
“In many parts of the world where there have not been any large movements of population over a long period, the reality of subraces is evident enough” (p211).
One suspects that, given increased geographic mobility, those parts of the world are now reduced in number.
Thus, even if subracial differences were once real, with increased migration and intermarriage, they are fast disappearing, at least within Europe.
“Studies of Selected Human Groups”
This third section of the book focuses on certain specific selected human populations. These are presumably chosen because Baker feels that they are representative of certain important elements of human evolution, racial divergence, or are otherwise of particular interest.
Unfortunately, Baker’s choice of which groups upon which to focus seems rather arbitrary and he never explains why these groups were chosen ahead of others.
In particular, it is notable that Baker focuses primarily on populations from Europe and Africa. East Asians (i.e. ‘Mongoloids’), curiously, are entirely unrepresented.
After a couple of introductory chapters, and one chapter focussing on “Europids” (i.e. Caucasians) as a whole, Baker’s next chapter discusses Jewish people.
In the opening paragraphs, he observes that:
“In any serious study of the superiority or inferiority of particular groups of people one cannot fail to take note of the altogether outstanding contributions made to intellectual and artistic life, and to the world of commerce and finance, generation after generation by persons to whom the name of Jews is attached” (p232).
However, having taken due “note” of this, and hence followed his own advice, he says almost nothing further on the matter, either in this chapter or in those later chapters that deal specifically with the question of racial superiority (see below).
Instead, Baker first focuses on justifying the inclusion of Jews in a book about race, and hence arguing against the politically-correct notion that Jews are not a race, but rather mere practitioners of a religion. Baker gives short-shrift to this notion:
In other words, Baker seems to be saying, because Judaism is not a religion that actively seeks out converts (but rather one that, if anything, discourages conversion), Jews have retained an ethnic character distinct from the host populations alongside whom they reside, without having their racial traits diluted by the incorporation of large numbers of converts of non-Jewish ancestry.
Yet, actually, even proselytizing religions like Christianity, Catholicism and Islam, that do actively seek to convert nonbelievers, often come to take on an ethnic character, since offspring usually inherit (i.e. are indoctrinated in) the faith of their parents, apostates are persecuted, conversion remains, in practice, rare, and people are admonished to marry ‘within the faith’.
These include a short but wide skull and a nose that is “large in all dimensions” (p239), the characteristic shape of which Baker even purports to illustrate with a delightfully offensive diagram (p241).
Likewise, Baker claims that Sephardic Jews, the other main subgroup of European Jews, are likewise “distinguishable from the Ashkenazim by physical characters”, being slenderer in build, with straighter hair, narrower noses, and different sized skulls, approximately more to the Mediterranean racial type (p245-6).
But, if Sephardim and Ashkenazim are indeed “distinguishable” or “recognisable” by “physical characters”, either from one another or from other European Gentiles, as Baker claims, then with what degree of accuracy is he claiming such distinctions can be made? Surely far less than 100%.
Moreover, are the alleged physiological differences that Baker posits between Ashkenazi, Sephardi, and other Europeans based on recorded quantitative measurements, and, if so, are the differences in question statistically significant? On this, Baker says nothing.
The next chapter concerns “The Celts”, a term surrounding which there is so much confusion and which has been used in so many different senses – racial, cultural, ethnic, territorial and linguistic (p183) – that some historians have argued that it is best abandoned altogether.
Baker, himself British, is keen to dispel the notion that the indigenous populations of the British Isles were, at the time of the Roman invasion, a primitive people, and is very much an admirer of their artwork.
Thus, Baker writes that:
“Caesar… nowhere states that any of the Britons were savage (‘immanis’), nor does he speak specifically of their ignorance (‘ignorantia’), though he does twice mention their indiscretion (‘imprudentia’) in parleying” (p263).
Of course, Caesar, though hardly unbiased in this respect, did regard the indigenous Britons as less civilized than the Romans themselves. However, I suppose that barbarism, like civilization (see below), is a matter of degree.
“Their skulls scarcely differ from those of the Anglo-Saxons who subsequently dominated them, except in one particular character, namely, that the skull is slightly (but significantly) lower in the Iron Age man than in the Anglo-Saxon” (p257).
Thus, dismissing the politically-correct notion that the English were, in the words of another author, “a truemultiracialsociety”, Baker claims:
Citing remains found in an ancient cemetery in Berkshire supposedly containing the skeletons of Anglo-Saxon males but indigenous British females and hybrid offspring, he concludes that, rather than extermination, a process of intermarriage and assimilation occurred (p266).
However, the indigenous pre-Celtic inhabitants of the British Isles were, he concludes, less Nordic than Mediterranid in phenotype.
Such influences remain, Baker claims, in the further reaches of Wales and Ireland, as evidenced by the distribution of blood groups and of hair colour.
“The tendency towards the possession of dark hair was much more marked in Wales than in England, and still more marked in the western districts of Ireland” (p265).
This conclusion is based upon the observations of nineteenth century English ethnologist John Beddoe, who travelled the British Isles recording the distribution of different hair and eye colours, reporting his findings in The Races of Britain, which was first published in 1862 and remains, to my knowledge, the only large body of data on the distribution of hair and eye colour in the British Isles to this day.
Yet recent population genetic studies suggest that even the so-called Celts, like the later Anglo-Saxons, Normans and Vikings, actually had only a quite minimal impact on the ancestry of the indigenous peoples of the British Isles.
The Celts, moreover, likely arrived from on the British Isles from continental Europe by the same route as the later Anglo-Saxons and Normans – i.e. across the English channel (or perhaps the south-west corner of the North Sea), by way of Southern England. This is, after all, by far the easiest, most obvious and direct route.
This leads Baker to conclude that the Celts, like the Anglo-Saxons after them, imposed their language on, but had little genetic impact on, the inhabitants of those parts of the British Isles furthest from this point of initial disembarkation (i.e. Scotland, Ireland, Wales). Thus, Baker concludes:
“The Iron Age invaders transmitted the dialects of their Celtic language to the more ancient Britons whom they found in possession of the land [and] pushed back these less advanced peoples towards the west and north as they spread” (p264).
But these latter peoples, though adopting the Celtic tongue, were not themselves (primarily) descendants of the Celtic invaders. This leads Baker to follow Carleton Coon in concluding:
“It is these people, the least Celtic—in the ethnic sense—of all the inhabitants of Great Britain, that have clung most obstinately to the language that their conquerors first taught them two thousand years ago” (p269).
In other words, in a racial and genetic, if not a linguistic, sense, the English are actually more Celtic than are the self-styled ‘Celtic Nations’ of Scotland, Ireland and Wales!
However, this is not what Baker means by referring to Aboriginals as “primitive”. Indeed, unlike his later chapters on black Africans, Baker says nothing regarding the technology or culture of indigenous Australians.
Instead, he talks exclusively about their morphology. In referring to them as “primitive”, Baker is therefore using the word in the specialist phylogenetic sense. Thus, he argues that Australian Aboriginals:
“Retain… physical characters that were possessed by remote ancestors but have been lost in the course of evolution by most members of the taxa that are related to it” (p272-3).
In other words, they retain traits characteristic of an earlier state of human evolution which have since been lost in other extant races.
Baker purports to identify twenty-eight such “primitive” characters in Australian aboriginals. These include prognathism (p281), large teeth (p289), broad noses (p282), and large brow ridges (p280).
Baker acknowledges that all extant races retain some primitive characters that have been lost in other races (p302). For example, unlike most other races (but not Aboriginals), Caucasoids retain scalp hair characteristic of early hominids and indeed other extant primates (p297).
However, Baker concludes:
“The Australids are exceptional in the number and variety of their primitive characters and in the degree to which some of them are manifested” (p302).
More obviously, phylogentically ‘primitive’ brains obviously also imply lesser intelligence, given the increase in human brain size and intelligence that has occurred over the course of human evolution.
In this sense, then, Australian Aboriginals ‘primitive’ brains may indeed be linked to the primitive state, in the more familiar sense of the word ‘primitive’, of their technology and culture.
San Bushmen and Paedomorphy
Whereas Australian Aboriginals are morphologically “primitive” (i.e. retain characters of early hominids), the San Bushmen of Southern Africa (“Sanids”), together with the related Khoi (collectively Khoisan, or, in racial terms, Capoid) are, Baker contends, “paedomorphic”.
By this, Baker means that the San people retain into adulthood traits that are, in other taxa, restricted to infants or juveniles, and is more often referred to as neoteny.
“The penis, when not erect, maintains an almost horizontal position… This feature is scarcely ever omitted in the rock art of the Bushmen, in their stylized representations of their own people. The prepuce is very long; it covers the glans completely and projects forward to a point. The scrotum is drawn up close to the root of the penis, giving the appearance that only one testis has descended, and that incompletely” (p319).
Humans in general are known to be neotenous in many of our distinct characters, and we are also, of course, the most intelligent known species. However, Baker argues:
“Although mankind as a whole is paedomorphous, those ethnic taxa (the Sanids among them) that are markedly more paedomorphious than the rest have never achieved the status of civilization, or anything approaching it, by their own initiative. It would seem that, when carried beyond a certain point, paedomorphosis is antagonistic to purely intellectual advance” (p324).
As to why this might be the case, he speculates in a later chapter:
“Certain taxa have remained primitive or become paedomorphous in their general morphological characters and none of these has succeeded in developing a civilization. It is among these taxa in particular that one finds some indication of a possible cause of mental inferiority in the small size of the brain” (p428).
Having discussed male genitalia, Baker also emphasizes the primary and secondary sexual characteristics of Sanid women – in particular their protruding buttocks (“steatopygia”) and alleged elongated labia.
The protruding buttocks of Sanid women are, Baker contends, qualitatively different in both shape and indeed composition from those of other populations, including the much-celebrated ‘big butts’ of contemporary African-Americans (p318).
Thus, whereas, among other populations, the shape of the buttocks, even if very large, are “rounded” in shape:
“It is particular characteristic of the Khoisanids that the shape of the projecting part is that of a right-angled triangle, the upper edge being nearly horizontal … [and] internally… consist of masses of fat incorporated between criss-crossed sheets of connective tissue said to be joined to one another in a regular manner.”
Regarding the function of these enlarged buttocks, Baker rejects any analogy with the humps of the camel, which evolved as reserves of fat upon which the animal could call in the event of famine or draught.
Unlike camels, which are, of course, adapted to a desert environment, Baker concludes:
However, although he does not directly discuss this, Baker presumably regards this as a recent displacement, resulting from the Bantu expansion, in the course of which the less advanced San were displaced from their traditional hunting grounds in southern Africa by Bantu agriculturalists, and permitted to eke out an undisturbed existence only in an arid desert environment of no use to Bantu agriculturalists.
Instead of having evolved as fat reserves in the event of famine, drought or scarcity, Baker instead suggests that Khoisan buttocks evolved through sexual selection.
The caloric demands of pregnancy and lactation are indeed the probable reason women of all races have greater fat deposits than do males.
Indeed, an analogy might be provided by female breasts, since these, unlike the mammary glands of other mammalian species, are present permanently, from puberty on, and, save during pregnancy and lactation, are composed predominantly of fatty tissues, not milk.
Elusive Elongated Labia?
In addition to their enlarged buttocks, Baker also discusses the alleged elongated labia of Sanid women, sometimes referred to, rather inaccurately in Baker’s view, as the “the Hottentot apron”.
Some writers have discounted this notion as a sort of nineteenth-century anthropological myth. However, Baker himself insists that the elongated labia of the San are indeed real.
The fourth and final section of ‘Race’ turns to the most controversial topic addressed by Baker in this most controversial of books, namely whether any racial group can be said to be superior or inferior to another, a question that Baker christens “the Ethnic Question”.
He begins by critiquing the very nature of the notion of superiority and inferiority, observing in a memorable and quotable aphorism:
Thus, if one is “concerned simply with the question whether the taxa are similar or different”, then, Baker concludes, “there can be no doubt as to the answer” (p421).
Indeed, this much is clear, not simply from the huge amount of data assembled by Baker himself in previous chapters, but also from simple observation.
However, Baker continues:
“The words ‘superior’ and ‘inferior’ are not generally used unless value judgements are concerned” (p421).
Any value judgement is, of course, necessarily subjective.
On objective criteria, each race can only be said to be, on average, superior in a specific endeavour (e.g. IQ tests, basketball, mugging, pimping, drug-dealing, tanning, making music, building civilizations). The value to be ascribed to these endeavours is, however, wholly subjective.
On these grounds, contemporary self-styled ‘race realists’ typically disclaim any association between their theories and any notions of racial superiority.
Although he alludes in passing to race differences in athletic ability, Baker, in discussing superiority, is concerned primarily with intellectual and moral achievement. Therefore, in this final section of the book, he turns from physiological differences to psychological ones.
Of course, the two are not entirely unconnected. All behaviour must have an ultimate basis in the brain, which is itself a part of an organism’s physiology. Thus:
“Cranial capacity is, of course, directly relevant to the ethnic problem since it sets a limit to the size of the brain in different taxa; but all morphological differences are also relevant in an indirect way, since it is scarcely possible that any taxa could be exactly the same as one another in all the genes that control the development and function of the nervous and sensory systems, yet so different from one another in structural characters in other parts of the body” (p533-4).
Indeed, Baker observes:
“Identity in habits is unusual even in pairs of taxa that are morphologically much more similar to one another than [some human races]. The subspecies of gorilla, for instance, are not nearly so different from one another as Sanids are from Europids, but they differ markedly in their modes of life” (426).
In other words, since human races differ significantly in their physiology, it is probable that they will also differ, to a roughly equivalent degree, in psychological traits, such as intelligence, temperament and personality.
In discussing the question of the intellectual and moral superiority of different racial groups, Baker focusses on two lines of evidence in particular:
While his data on race differences in IQ is therefore now dated, Baker’s discussion of the track-record of different races in founding civilizations remains of interest today, if only because this is a topic studiously avoided by most contemporary authors, historians and anthropologists on account of its politically-incorrect nature – though Jared Diamond, in Guns, Germs and Steel, represents an important recent exception to this trend.
The first question, of course, is precisely how one is to define ‘civilizations’ in the first place, itself a highly contentious issue.
Thus, Baker identifies twenty-one criteria for recognising civilizations (p507-8).
However, the latter are inherently problematic. What constitutes moral superiority itself involves a moral judgement that is necessarily subjective.
In other words, whereas technological and scientific superiority can be demonstrated objectively, moral superiority is a mere matter of opinion.
Thus, the ancient Romans, transported to our times, would surely accept the superiority of our technology – and, if they did not, we would, as a consequence of the superiority of our technology, outcompete them both economically and militarily and hence prove it ourselves.
Take, for example, Baker’s first requirement for civilization, namely that:
“In the ordinary circumstances of life in public places they [i.e. members of the society under consideration] cover the external genitalia and greater part of the trunk with clothes” (p507).
This criterium is not only curiously puritanical, but also blatantly biased against tropical cultures. Whereas in temperate and arctic zones clothing is essential for survival, in the tropics the decision to wear clothing represents little more than an arbitrary fashion choice.
The requirement that a civilization’s religious beliefs not be “purely or grossly superstitious” (p507) is also problematic. As a confirmed atheist, I suspect that all religions are, by very definition, superstitious. If some forms of Buddhism and Confucianism are perhaps exceptions, then they are perhaps simply not religions at all in the western sense.
As for his complaint that the religion of the Mayans “did not enter into the fields of ethics” (p526), a complaint he also raises in respect of indigenous black African religions (p384), contemporary moral philosophers generally see this as a good thing, believing that religion is best kept of moral debates.
However, in doing so, he is judging the cultures in question by distinctly Western moral standards. The Aztecs, in contrast, may have viewed human sacrifice as a moral imperative and may therefore have viewed European cultures as morally deficient precisely because they did not butcher enough of their people in order to propitiate the gods.
Likewise, whereas Baker views cannibalism as incompatible with civilization (p507), I personally view cannibalism as, of itself, a victimless crime. A dead person, being dead, is incapable of suffering by virtue of being eaten. Indeed, in this secular age of environmental consciousness, one might even praise cannibalism as a highly ‘sustainable’ form of recycling.
Whereas his previous chapters discussing specific selected human populations focussed primarily, or sometimes exclusively, on their morphological peculiarities, in the last four of these chapters, focussing on African blacks, his focus shifts from morphology to culture.
Thus, Baker writes:
“The physical characters of the Negrids are mentioned only briefly. Members of this race are studied in Chapters 18-21 mainly from the point of view of the social anthropologist interested in their progress towards civilization at a time when they were still scarcely influenced over a large part of their territory, by direct contact with members of more advanced ethnic taxa” (p184).
Unlike some racialist authors, Baker acknowledges the widespread adoption of advanced technologies throughout much of sub-Saharan Africa prior to modern times. However, he attributes the adoption of these technologies to contact with, and borrowings from, outside non-Negroid civilizations (e.g. Arabs, Egyptians, Moors, Berbers, Europeans).
Therefore, in order to distinguish the indigenous, homegrown capacity of black Africans to develop advanced civilization, Baker relies on the reports of seven nineteenth century explorers of what he terms “the secluded area” of Africa, by which term Baker seems to mean the bulk of inland Southern, Eastern and Central Africa, excluding the Horn of Africa, the coast of West Africa and the Gulf of Guinea (p334-5).
In these parts of Africa, at the time these early European explorers visited the continent, the influence of outside civilizations was, Baker reports, “non-existent or very slight” (p335). The cultural practices observed by these explorers therefore, for Baker, provide a measure of black Africans’ indigenous capacity for social, cultural and technological advancement.
On this perhaps dubious basis, Baker thus concludes that there is no evidence black Africans ever:
Fully domesticated any plants (354-6) or animals (p373-7); or
Invented the wheel (p373); or other ‘mechanical’ devices with interacting parts (p354).
Also largely absent throughout ‘the secluded area’, according to Baker, were:
Let’s review these claims in turn. First, it certainly seems to be true that few if any species of either animals or plants were domesticated in what Baker calls the “the secluded area” of sub-Saharan Africa.
However, with respect to plants, there may be a reason for this. Many important, early domesticates were annuals. These are plants that complete their life-cycle within a single year, taking advantage of predictable seasonal variations in the weather.
“Within their mere one year of life, annual plants inevitably remain small herbs. Many of them instead put their energy into producing big seeds, which remain dormant during the dry season and are then ready to sprout when the rains come. Annual plants therefore waste little energy on making inedible wood or fibrous stems, like the body of trees and bushes. But many of the big seeds… are edible by humans. They constitute 6 of the modern world’s 12 major crops” (Guns, Germs and Steel: p136).
However, the wild auroch, from whom modern cattle derive, was undoubtedly even more formidable, being, not only larger, more muscled and with bigger horns, but also surely even more aggressive than modern bulls. After all, one of the key functions of domestication is to produce more docile animals that are more amenable to control by human agriculturalists.
Compared to the domestication of aurochs, the domestication of the zebra would seem almost straight forward. Indeed, the successful domestication of aurochs in ancient times might even cause us to reserve our judgement regarding the domesticability of such formidable African mammals as hippos and African buffalo, the possibility of whose domestication Diamond dismisses a priori as preposterous.
Certainly, the domestication of the auroch surely stands as one of the great achievements of ancient Man.
Reinventing the Wheel?
Baker also seems to be correct in his claim that black Africans never invented the wheel.
However, it must be borne in mind that the same is also probably true of white Europeans, who, rather than independently inventing the wheel for themselves, had the easier option of simply copying the design of the wheel from other civilizations and peoples, namely those from the Middle East, probably Mesopotamia, where the wheel seems to be have first been developed.
Indeed, most cultures with access to the wheel never actually invented it themselves, for the simple reason that it is far easier to copy the invention of a third-party through simple reverse engineering than to independently invent afresh an already existing technology all by oneself.
The real question, then, is not why the wheel was never invented in sub-Saharan Africa, but rather why it failed to spread throughout that continent in the same way it did throughout Eurasia.
Thus, if the wheel was known, as Baker readily acknowledges it was, in those parts of sub-Saharan Africa that were in contact with outside civilizations (notably in the Horn of Africa), then this raises the question as to why it failed to spread elsewhere in Africa prior to the arrival of Europeans. This indeed is acknowledged to remain a major enigma within the field of African history and archaeology (Law 2011; Chavez et al 2012).
After all, there are no obvious insurmountable geographical barriers preventing the spread of technologies across Africa other than the Sahara itself, and, as Baker himself acknowledges, black Africans in the ‘penetrated’ area had proven amply capable of imitating technological advances introduced from outside.
Why then did the wheel not spread across Africa in the same way it did across Eurasia? Is it possible that African people’s alleged cognitive deficiencies were responsible for the failure of this technology to spread and be copied, since the ability to copy technologies through reverse engineering itself requires some degree of intellectual ability, albeit less than that required for original innovation?
One might argue instead that the African terrain was unsuitable for wheeled transport. However, one of the markers of civilization is surely its very ability to alter the terrain by large, cooperative public works engineering projects, such as the building of roads.
Thus, most of Eurasia is now suitable for wheeled transport in large part only because we, or more specifically our ancestors, have made it so.
Another explanation sometimes offered for the failure of African to develop wheeled transportation is that they lacked a suitable draft animal, horses being afflicted with sleeping sickness spread by the tsetse fly.
However, as we have seen above, Baker argues a race’s track record in successfully domesticating wild animals is itself indicative of the intellectual ability and character of that race. For Baker, then, the failure of sub-Saharan African to successfully domesticate any suitable species of potential draft animal (e.g. the zebra: see above) is itself indicative of, and a factor in, their inability to successfully develop advanced civilization.
At any rate, even in the absence of a suitable draft animal, wheels are still useful.
On the one hand, they can be used for non-transport-related purposes (e.g. the spinning wheel, the potter’s wheel, even water wheels). Indeed, in Eurasia the invention of the potter’s wheel is actually thought to have preceded the use of wheels for the purposes of transportation.
In other words, humans can themselves be employed as a draft animal, whether by choice or by force, and, if there is one arguable marker for civilization for which Africa did not lack, and which did not await introduction by Europeans, Moors and Arabs, it was, of course, the institution of slavery.
African Writing Systems?
What then of the alleged failure of sub-Saharan Africans to develop a system of writing? Baker refers to only a single writing system indigenous to sub-Saharan Africa, namely the Vai syllabary, invented in what is today Liberia in the nineteenth century in imitation of foreign scripts. Was this indeed the only writing system indigenous to sub-Saharan Africa?
Of course, writing has long been known in North Africa, and ancient Egypt even lays claim to have invented the first written script, namely hieroglyphs, although most archaeologists believe that they were beaten to the gun, once again, by Mesopotamia, with its cuneiform script.
However, this is obviously irrelevant to the question of black African civilization, since the populations of North Africa, including the ancient Egyptians, were largely Caucasoid.
However, save for those of recent origin, almost all of these writing systems seem, from the descriptions on their respective wikipedia pages, to have been restricted to areas outside of ‘the secluded area’ of Africa as defined by Baker (p334-5).
The only ancient writing system mentioned on this wikipedia page that was found in what Baker calls ‘the secluded area’ of Africa isLusona. This seems to have been developed deep in the interior of sub-Saharan Africa, in parts of what is today eastern Angola, north-western Zambia and adjacent areas of the Democratic Republic of the Congo. Thus, it is almost certainly of entirely indigenous origin.
It therefore appears to fall far short of a fully developed script in the modern sense.
Indeed, the same seems to be true, albeit to a lesser extent, of most of the indigenous writing systems of sub-Saharan Africa listed on the wikipedia page, namely Nsibidi and Adrinka, which each seem to represent only a form of proto-writing.
Only Ge’ze seems to have been a fully-developed script, and this was used only in the Horn of Africa, which not only lies outside ‘the secluded area’ as defined by Baker, but whose population is, again according to Baker, predominantly Caucasoid (p225).
Also, Ge’ze seems to have developed from an earlier Middle Eastern script. It is therefore not of entirely indigenous African origin.
It therefore seems to indeed be true that sub-Saharan Africans never produced a fully-developed script in those parts of Africa where they developed beyond the influence of foreign empires.
However, it must here be emphasized that the same is again probably also true of indigenous Europeans.
Indeed, most writing systems were developed, if not directly from, then at least in imitation of, pre-existing scripts. Like the wheel, writing has only been independently reinvented afresh a few times in history.
The question, then, as with the wheel, is, not so much why much of sub-Saharan Africa failed to invent a written script, but rather why those written scripts that were in use in certain parts of the continent south of the Sahara, nevertheless failed to spread or be imitated over the remainder of that continent.
African Culture: Concluding Thoughts
In conclusion, it certainly seems clear that much of sub-Saharan Africa was indeed backward in those aspects of technology, social structure and culture which Baker identifies as the key components of civilization. This much is true and demands an explanation.
However, blanket statements regarding the failure of sub-Saharan Africans to develop a writing system or two-storey buildings seem, at best, a misleading simplification.
Indeed, Baker’s very notion of what he calls ‘the secluded area’ of Africa is vague and ill-defined, and he never provides a clear definition, or, better still, a map precisely delineating what he means by the term (p334-5).
Indeed, the very notion of a ‘secluded area’ is arguably misconceived, since even relatively remote and isolated areas of the continent that did not have any direct contact with non-Negroid peoples, will presumably have had some indirect influence from outside of sub-Saharan Africa, if only by contact with peoples from those regions of the continent south of the Sahara which had been influenced by foreign peoples and civilizations.
After all, as we have seen, Europeans also failed to independently develop either the wheel and writing system for themselves, instead simply copying these innovations from the neighbouring civilizations of the Middle East.
Why then were black Africans south of the Sahara, who were indeed exposed to these technologies in certain parts of their territory, nevertheless unable to do the same?
Perhaps one factor impeding the movement of technologies such as the wheel and writing across sub-Saharan Africa in pre-modern times is the relative lack of navigable waterways (e.g. rivers) in the region.
As emphasized by Tim Marshall in his book Prisoners of Geography, rivers in sub-Saharan African tended to be non-navigable, mainly because of the prevalence of large waterfalls that made transport by river a dangerous venture.
Since, in ancient and premodern times, transport by river was, at least in Eurasia, generally easier, safer and quicker than by land, Africa’s generally non-navigable river system may have ironically impeded the spread throughout Africa even of technologies that were themselves of use primarily for transportation, such as the wheel.
Pre-Columbian Native American Cultures
Baker’s discussion of status of the pre-Columbian civilizations, or putative civilizations, of America is especially interesting. Of these, the Mayans definitely stand out, in Baker’s telling, as the most impressive in terms of their scientific and technological achievements.
Baker ultimately concludes, however, that even the Maya do not qualify as a true civilization, largely on moral grounds – namely, their practice of mass sacrifices and cannibalism.
No doubt if western cultures were to be judged by the moral values of the Mayans, we too would be judged just as harshly. Perhaps they would condemn us precisely for not massacring enough of our citizens in order to propitiate the gods.
However, even seeking to rank the Mayans based solely on their technological and scientific achievements, they still represent something of a paradox.
Indeed, Baker educates us that it is was Mayans, not the Hindus or Arabs more often credited with the innovation, who first invented the concept of zero – or rather, to put the matter more precisely, “invent[ed] a ‘local value’ (or ‘place notational’) system of numeration that involved zero: that is to say, a system in which the value of each numberical symbol depended on its position in a series of such symbols, and the zero, if required, took its place in this series ” (p552).
Thus, Baker writes:
“The Maya had invented the idea [of zero] and applied it to their vegisimal system [i.e. using a base of twenty] before the Indian mathematicians had thought of it and used it in denary[i.e. decimal] notation” (p522).
However, on the other hand, according to Baker’s account:
“They had no weights… no metal-bladed hoes or spades and no wheels (unless a few toys were actually provided with wheels and really formed part of the Mayan culture)” (p524).
Yet, as Baker alludes to in his rather disparaging reference to “a few toys”, it now appears the these toys were indeed part of the Maya culture.
Thus, far from failing to invent the wheel, Native Americans are one of the few peoples in the world with an unambiguous claim to have indeed invented the wheel entirely independently, since the possibility of wheels being introduced through contact with Eurasian civilizations is exceedingly remote.
Thus, the key question is, not why Native American civilizations failed to invent the wheel, for they did indeed invent the wheel, but rather why they failed to make full use of this remarkably useful invention, seemingly only employing it for seemingly frivolous items resembling toys (but whose real purpose is unknown) rather than for transport, or indeed the production of ceramics, textiles or energy.
Terrain may have been a factor. As mentioned above, one of the markers of a true civilization is arguably its very ability to alter its terrain by large-scale engineering projects such as the building of roads. However, obviously some terrains pose greater difficulties in this respect, and the geography of much of Mesoamerica is particularly uninviting.
The Inca, but not the Aztecs and Maya, did have the llama. However, llama are not strong enough to carry humans, or to pull large carts.
Of course, for Baker, as we have seen above, a race’s track record in domesticating non-human animals, including for use as draft animals, is itself indicative of that race’s ability and capacity to build and maintain advanced civilization.
However, in the Americas, most large wild mammals of the sort possibly suited for domestication as a draft animal were wiped out by the first humans to arrive on the continent, the former having evolved in complete isolation from humans, and hence being completely evolutionarily unprepared for the sudden influx of humans with their formidable hunting skills.
However, it is simply not true that, in the absence of a draft animal, wheels vehicles “offered no advantage over human porters”, as claimed by Diamond. On the contrary, as dicussed above, humans themselves can be employed as draft animals (e.g. the wheelbarrow and pulled rickshaw), and, as Diamond himself observes in a later chapter:
“Human-powered wheelbarrows… enabled one or more people, still using just human muscle power, to transport much greater weights than they could have otherwise” (Guns Germs and Steel: p359).
Moreover, as again discussed above, the wheel also has other uses besides transport, one of which, the potter’s wheel, actually seems to have been adopted before the use of wheels for transportation purposes in Europe. Yet there is no evidence for the use of the potter’s wheel in the Americas prior to the arrival of Europeans.
As for the Mayan script, this was also, according to Baker, quite limited. Thus, Baker reports:
“There was no way of writing verbs, and abstract ideas (apart from number) could not be inscribed. It would not appear that the technique even of the Maya lent itself to a narrative form, except in a very limited sense. Most of the Middle Americans conveyed non-calendrical information only by speech or by the display of a series of paintings” (p524).
Indeed, he reports that “nearly all their inscriptions were concerned with numbers and the calendar” (p524).
“The Middle Americans had nothing that could properly be called a narrative script” (p523-4).
Baker vs Diamond: The Rematch
However, departing from Baker’s conclusions, I regard the achievements of the Mesoamerican civilizations as, overall, quite impressive.
This is especially so, not only when one takes into account, not only their complete isolation from the Old World civilizations of Eurasia, but also of other factors identified by Jared Diamond in his rightly-acclaimed Guns, Germs and Steel.
Thus, whereas the Eurasian cultural zone is oriented largely on an east-to-west axis, spreading from China and Japan in the East, to western Europe and North Africa in the West, America is a tall, narrow continent that spreads instead from north-to-south, quite narrow in places, especially at the Isthmus of Panama, where the North American continent meets South America, which, at the narrowest point, is less than fifty miles across.
As Diamond emphasizes, because climate varies with latitude (i.e. distance from the equator), this means that different parts of the Americas have very different climates, making the movement and transfer of crops, domesticated animals and people much more difficult.
This, together with the difficulty of the terrain, might explain why even the Incas and Aztecs, though contemporaneous, seem to have been largely if not wholly unaware of one another’s existence, and certainly had no direct contact.
As a result, Native American cultures developed, not only in complete isolation from Old World civilizations, but even largely in isolation even from one another.
Moreover, the Americas had few large domesticable mammals, almost certainly because the first settlers of the continent, on arriving, hunted them to extinction on first arrival, and the mammals, having evolved in complete isolation from humans, were entirely unprepared for the arrival of humans, with their formidable hunting skills, to whom they were wholly unadapted.
In these conditions, the achievements of the Mesoamerican civilizations, especially the Mayans, seem to me quite impressive, all things considered – certainly far more impressive than the achievements of, say, sub-Saharan Africans or Australian Aboriginals.
This is especially so in comparison to sub-Saharan Africa when one takes into consideration the fact that the latter region was neither completely isolated from Eurasian civilizations nor as narrowly oriented on a north-west as are the Americas.
Thus, as has been emphasized by astrophysicist Michael Hart in his book, Understanding Human History, Diamond’s theory is a rather more successful explanation for the technological backwardness and underdevelopment of the pre-Columbian Americas than it is for the even greater technological backwardness and underdevelopment of sub-Saharan Africa.
Thus, if these black Africans and Australian Aboriginals can then indeed be determined to possess lesser innate intellectual capacity as compared to, say, Europeans or East Asians, then I feel it is nevertheless premature to say the same of the indigenous peoples of the Americas.
In addition to ranking cultures on scientific, technological and moral criteria, Baker also assesses the quality of their artwork (p378-81; p411-17; p545-549). However, judgements of artistic quality, like moral judgements, are necessarily subjective.
However, interestingly, with regard to styles of music, Baker recognises the possibility of cultural bias, suggesting that European explorers, looking for European-style melody and harmony, failed to recognise the rhythmical qualities of African music which are, Baker remarks, “perhaps unequalled in the music of any other race of mankind” (p379).
“A Reminder of What Was Possible”?
The fact that ‘Race’ remains a rewarding some read forty years after first publication, is an indictment of the hold of politically-correctness over both science and the publishing industry.
In the intervening years, despite all the advances of molecular genetics, the scientific understanding of race seems to have progressed but little, impeded by political considerations.
Meanwhile, the study of morphological differences between races seems to have almost entirely ceased, and a worthysuccessor to Baker’s ‘Race’, incorporating the latest genetic data, has, to my knowledge, yet to be published.
Today, some forty years after Baker penned these very words and as the boundaries of acceptable opinion have narrowed yet further, I recommend Baker’s ‘Race’ in much the same spirit – as both an historical document and “a reminder of what was possible”.
 Genetic studies often allow us distinguish homology from analogy, because the same or similar traits in different populations often evolve through different genetic mutations. For example, Europeans and East Asians evolved lighter complexions after leaving Africa, in part, by mutations in different genes (Norton et al 2007). Similarly, lactase persistence has evolved through mutations in different genes in Europeans than among some sub-Saharan Africans (Tishkoff et al 2009). Of course, at least in theory, the same mutation in the same gene could occur in different populations, thus providing an example of convergent evolution and homoplasy even at the genetic level. However, with the analysis of a large number of genetic loci, especially in non-coding DNA, where mutations are unlikely to be selected for or against and hence are lost or retained at random in different populations, this problem is unlikely to lead to errors in determining the relatedness of populations.
In his defence, the Ainu are not one of the groups upon whom Baker focuses in his discussion, and are only mentioned briefly in passing (p158; p173; p424) and at the very end of the book, in his “Table of Races and Subraces”, where he attempts to list, and classify by race, all the groups mentioned in the book, howsoever briefly (p624-5).
Although we no longer need to rely on morphological criteria in order to determine the relatedness between populations, differences between racial groups in morphology and bodily structure remain an interesting, and certainly a legitimate, subject for scientific study in their own right. Unfortunately, however, the study and measurement of such differences seems to have all but ceased among anthropologists. One result is that much of the data on these topics is quite old. Thus, HBDers, Baker included, are sometimes criticized for citing studies published in the nineteenth and early-twentieth century. In principle, there is, however, nothing wrong with citing data from the nineteenth or early-twentieth century, unless critics can show that the methodology adopted have subsequently been shown to be flawed. However, it must be acknowledged that the findings of such studies with respect to morphology may no longer apply to modern populations, as a result of recent population movements and improvements in health and nutrition, among other factors. At any rate, the reason for the paucity of recent data is the taboo associated with such research.
This is a style of formatting I have not encountered elsewhere. It makes it difficult to bring oneself to skip over the material rendered in smaller typeface since it is right there in the main body of the text, and indeed Baker himself claims that this material is “more technical and more detailed than the rest (but not necessarily less interesting)” (pix).
Yet another source of potential terminological confusion results from the fact that, as will be apparent from many passages from the book quoted in this review, Baker uses the word “ethnic” to refer to differences that would better to termed “racial” – i.e. when referring to biologically-inherited physical and morphological differences between populations. Thus, for example, he uses the term “ethnic taxon” as “a comprehensive term that can be used without distinction for any of the taxa that are minor to species: that is to say, races, subraces and local forms” (p4). Similarly, he uses the phrase “the ethnic problem” to refer to the “whole subject of equality and inequality among the ethnic taxa of man” (p6). However, as Baker acknowledges, “English words derived from the Greek ἔθνος (ethnic, ethnology, ethnography, and others) are used by some authors in reference to groups of mankind distinguished by cultural or national features, rather than descent from common ancestors” (p4). However, in defending his adoption of this term, he notes “this usage is not universal” (p4). This usage has, I suspect, become even more prevalent in the years since the publication of Baker’s book. However, in my experience, the term ‘ethnic’ is sometimes also used as politically correct euphemism for the word ‘race’, both colloquially and in academia.
In both cases, the source of potential confusion is the same, since both terms, though referring to a race, are derived from geographic terms (Europe and the Caucasus region, respectively), yet the indigenous homelands of the races in question are far from identical to the geographic region referred to by the term. The term ‘Asian’, when used as an ethnic or racial descriptor, is similarly misleading. For example, in British-English, ‘Asian’, as an ethnic term, usually refers to South Asians, since South Asians form a larger and more visible minority ethnic group in the UK than do East Asians. However, in the USA, the term ‘Asian’ is usually restricted to East Asians and Southeast Asians – i.e. those formerly termed ‘Mongoloid’. The British-English usage is more geographically correct, but racially misleading, since populations of the Indian subcontinent, like those from the Middle East (also part of the Asian continent) are actually genetically closer to southern Europeans than to East Asians and were generally classed as Caucasian by nineteenth and early-twentieth century anthropologists, and are similarly classed by Baker himself. This is one reason that the term ‘Mongoloid’, despite pejorative connotations, remains useful.
Moreover, the term ‘Mongoloid’ is especially confusing given that it has also been employed to refer to people suffering from a developmental disability and chromosomal abnormality (Down Syndrome), and, while both usages are dated, and the racial meaning is actually the earlier one from which the later medical usage is derived, it is the latter usage which seems, in my experience, to retain greater currency, the word ‘Mongoloid’ being sometimes employed as a rather politically-incorrect insult, implying a mental handicap. Therefore, while I find annoying the ‘euphemism treadmill’ whereby terms once quite acceptable terms (e.g. ‘negro’, ‘coloured people’) are suddenly and quite arbitrarily deemed offensive, the term ‘Mongoloid’ is, unlike these other etymologically-speaking, quite innocent terms, understandably offensive to people of East Asian descent given this dual meaning.
 For example, another ethnonym, ‘Asian’, is also etymologically problematic. Thus, the word ‘Asia’, the source of the ethnonym, ‘Asian’, derives from the Greek Ἀσία, which originally referred only to Anatolia, at the far western edge of what would now be called Asia, the inhabitants of which region are not now, nor have ever likely been, ‘Asian’in the current American sense. Indeed, the very term Asia is a Eurocentric concept, grouping together many diverse peoples, fauna, flora and geographic zones, and whose border with Europe is quite arbitrary. Another even more etymologically suspect ethonym is, of course, the term ‘Indian’ (and its derivatives ‘Amerindian’, ‘Red Indian’ and ‘American Indian’) when applied to the indigenous peoples of the Americas.
 The main substantive differences between the rival taxonomies of different racial theorists reflect the perennial divide between lumpers and splitters. There is also the question of precisely where the line is to be drawn between one race and another in clinal variation between groups, and whether a hybrid or clinal population sometimes constitutes a separate race in and of itself.
 Indeed, somewhat disconcertingly, even Hitler’s Mein Kampf is taken seriously by Baker, the latter acknowledging that “the early part of [Hitler’s] chapter dealing with the ethnic problem is quite well-written and not uninteresting” (p59) – or perhaps this is only to damn with faint praise.
To clarify, both Boas and Montagu are briefly mentioned in later chapters. For example, Boas’snow largely discredited work on cranial plasticity is discussed by Baker at the end of his chapter on ‘Physical Differences Between the Ethnic Taxa of Man: Introductory Remarks’ (p201-2). However, this is outside of Baker’s chapters on “The Historical Background”, and therefore Boas’s role in (allegedly) shaping the contemporary consensus of ‘race denial’ is entirely unexplored by Baker. For discussion on this topic, see Carl Degler’s In Search of Human Nature; see also Chapter Two of Kevin Macdonald’s The Culture of Critique (which I have reviewed here) and Chapter Three of Sarich and Miele’s Race: The Reality of Human Differences (which I have reviewed here, here and here).
Thus, there was no new scientific discovery that presaged or justified the abandonment of biological race as an important causal factor in the social and behavioural sciences. Later scientific developments, notably in genetics, were certainly later co-opted in support of this view. However, there is no coincidence in time between these two developments. Therefore, whatever the true origins of the theory of racial egalitarianism, whether one attributes it to horror at the misuse of race science by the Nazi regime, or the activism of certain influential social scientists such as Boas and Montagu, one thing is certain – namely, the abandonment, or at least increasing deemphasis, of the race category in the social and behavioural sciences was originally motivated by political rather than scientific considerations. See Carl Degler’sIn Search of Human Nature; see also Chapter 2 of Kevin Macdonald’s Culture of Critique (which I have reviewed here) and Chapter Three of Sarich and Miele’s Race: The Reality of Human Differences (which I have reviewed here, here and here).
 That OUP gave up the copyright is, of course, to be welcomed, since it means, rather than gathering dust on the shelves of university libraries, while the few remaining copies still in circulation from the first printing rise in value, it has enabled certain dissident publishing houses to release new editions of this now classic work.
This is, at least, how Baker describes this ‘species complex’ and how it was traditionally understood. Researching the matter on the internet, however, suggests whether this species complex represents a true ring species is a matter of some dispute (e.g. Liebers et al 2006).
 In cases of matings between sheep and goats that result in offspring, the resulting offspring themselves are usually, if not always, infertile. Moreover, actually, according to the wikipedia page on the topic, the question of when sheep and goats can ever successfully interbreed is more complex than suggested by Baker.
“The form of the skull of a child is directly connected with the characteristics of the structure of the mother’s pelvis—they should correspond to each other in the goal of eliminating death in childbirth. The mixing of the races unavoidably leads to this, because the structure of the pelvis of a mother of a different race does not correspond to the shape of the head of [the] mixed infant; that leads to complications during childbirth” (Raciology: p157).
“Women on lower races endure births very easily, sometimes even without any pain, and only in highly rare cases do they die from childbirth. But this can never be said of women of lower races who birth children of white fathers” (Raciology: p157).
Thus, he quotes an early-twentieth century Russian race theorist as claiming:
“American Indian women… often die in childbirth from pregnancies with a child of mixed blood from a white father, whereas pure-blooded children within them are easily born. Many Indian women know well the dangers [associated with] a pregnancy from a white man, and therefore, they prefer a timely elimination of the consequence of cross-breeding by means of fetal expulsion, in avoidance of it” (Raciology: p157-8).
This, interestingly, accords with the claim of infamous late-twentieth century race theorist J Philippe Rushton, in the ‘Preface to the Third Edition’ of his book Race, Evolution and Behavior (which I have reviewed here), that, as compared to whites and Asians, blacks have “narrower hips”, giving them “a more efficient stride”, which provides an advantage in many athletic events, and that:
“The reason Whites and East Asians have wider hips than Blacks, and so make poorer runners, is because they give birth to larger brained babies” (Race, Evolution and Behavior: p11-12).
However, contrary to the claim of Avdeyev, I find support from contemporary delivery room data, for the claim that women from so-called ‘lower-races’ experience greater birth complications, and mortality rates, when birthing offspring fathered by European males. On the contrary, it is only differences in overall body-size, not brain-size, that seem to be the key factor, with East Asian women having greater difficulties birthing offspring fathered by European males because of the smaller frames of East Asian women, even though East Asians have brains as large as or larger than those of Europeans (Nystrom et al 2008). Neither is it true that, where inter-racial mating has not occurred, then, on account of the small brain-size of their babies, “Women on lower races endure births very easily, sometimes even without any pain, and only in highly rare cases do they die from childbirth” (Raciology: p157). On the contrary. data from the USA seems to indicate a somewhat higher rate of caesarean delivery among African-American women as compared to white American women (Braveman et al 1995; Edmonds et al 2013; Getahun et al 2009; Valdes 2020.
 Examining the effects of interracial hybridization on other traits besides fertility, there are mixed results. Thus, one study reported what the authors interpreted as a hybrid vigour effect on g-factor of general intelligence among the offspring of white-Asian unions in Hawaii, as compared to the offspring of same-race couples matched for educational and occupational levels (Nagoshi & Johnson 1986). Similarly, Lewis (2010) attributed the higher attractiveness ratings accorded to the faces of mixed-race people to heterosis. Meanwhile, another study found that height was positively correlated with the distance between the birthplaces of one’s parents, itself presumably a correlate of their relatedness (Koziel et al 2011). On the other hand, however, behavioural geneticist Glayde Whitney suggests that hybrid incompatibility may explain the worse health outcomes, and shorter average life-spans, of African Americans as compared to whites in the contemporary USA, owing to the former’s mixed African and European ancestry (Whitney 1999). One specific negative health outcome for some African-Americans resulting from a history racial admixture is also suggested by Helgadottir et al (2006). It is notable that, whereas recent studies tend to emphasize the (supposed) positive genetic effects resulting from interracial unions, the older literature tends to focus on (supposed) negative effects of interracial hybridization (see Frost 2020). No doubt this reflects the differing zeitgeister of the two ages (Provine 1976; Khan 2011c).
Interestingly, while languages and cultures vary in the number of colours that they recognise and have words for, both the ordering of the colours recognised, and the approximate boundaries between different colours, seems to be cross-culturally universal. Thus, some languages have only two colour terms, which are always equivalent to ‘light’ and ‘dark’. Then, if a third colour terms is used, it is always equivalent to ‘red’. Next come either ‘green’ or ‘yellow’. Experimental attempts to teach colour terms not matching the familiar colours show that individuals learn these terms much less quickly than they do the colour familiar terms recognised in other languages. This, of course, suggests that our colour perception is both innately programmed into the mind and cross-culturally universal (see Berlin & Kay, Basic Color Terms: Their Universality and Evolution).
Indeed, as I discuss later, with respect to what Baker calls ‘subraces’, we may already have long previously passed this point, at least in Europe and North America. While morphological differences certainly continue to exist, at the aggregate, statistical level, between populations from different regions of Europe, there is such overlap, such a great degree of variation even within families, and the differences are so fluid, gradual and continuous, that I suspect such terms as the Nordic race, Alpine race, Mediterranid race and Dinaric race have likely outlived whatever usefulness they may once have had and are best retired. The differences are now best viewed as continuous and clinal.
 While Ethiopians and other populations from the Horn of Africa are indeed a hybrid or clinal population, representing an intermediate position between Caucasians and other black Africans, Baker perhaps goes too far in claiming:
“Aethiopids (‘Eastern Hamites’ or ‘Erythriotes’) of Ethiopia and Somaliland are an essentially Europid subrace with some Negrid admixture” (p225).
Thus, Lewontin famously showed that, when looking at individual genetic loci, most variation is within a single population, rather than between populations, or between races (Lewontin 1972). However, when looking at phenotypic traits that are caused by polygenes, it is easy to see that there are many such traits in which the variation within the group does not dwarf that between groups – for examp7e, differences in skin colour as between Negroes and Nordics, or differences in stature between as Pygmies and even neighbouring tribes of Bantu.
 In addition to discussing morphological differences between races, Baker also discusses differences in scent (170-7). This is a particularly emotive issue, given the negative connotations associated with smelling ‘bad‘. However, given the biochemical differences between races, and the fact that even individuals of the same race, even the same family, are distinguishable by scent, it is inevitable that persons of different races will indeed differ in scent, and unsurprising that people would generally prefer the scent of their own group. There is substantial anecdotal evidence that this is indeed the case. In general, Baker reports that East Asians have less body odour, whereas both Caucasoids and blacks have greater body odour. Partly this is explained by the relative prevalence of dry and wet ear wax, which is associated with body odour, varies by population and is one of the few easily detectable phenotypic traits in humans that is determined by simply Mendelian inheritance (see McDonald, Myths of Human Genetics). Intriguingly, Nicholas Wade speculates that dry earwax, which is associated with less strong body-odour, may have evolved through sexual selection in colder climates where, due to the cold, more time is spent indoors, in enclosed spaces, where body odour is hence more readily detectable, and producing less scent may have conferred a reproductive advantage (A Troublesome Inheritance: p91). This may explain some of the variation in the prevalence of dry and wet ear wax respectively, with dry earwax predominating only in East Asia, but also being found, albeit to a lesser degree, among Northern Europeans. On the other hand, however, although populations inhabiting colder climates may spend more time indoors, populations inhabiting tropical climates might be expect to sweat more due to the greater heat and hence build up greater bodily odour.
A few exceptions include where Baker discusses the small but apparently statistically significant differences between the skulls of ‘Celts’ and Anglo-Saxons (p257), and where he mentions statistically significant differences between ancient Egypian skulls and those of Negroes (p518).
 Thus, of the infamous Khazar hypothesis, now almost wholly discredited by genetic data, but still popular among some anti-Zionists, because it denies the historical connection between (most) contemporary Jews and the land of Israel, and among Christian anti-Semites, because it denies that the Ashkenazim are indeed ‘chosen people’ of the Old Testament, Baker writes:
“It is clear they [the Khazars] were not related, except by religion, to any modern group of Jews” (p34).
 Baker thus puts the intellectual achievements of the Ashkenazim in the broader context of other groups within this same subrace, including the Assyrians, Hittites and indeed Armenians themselves. Thus, he concludes:
“The contribution of the Armenid subrace to civilization will bear comparison with that of any other” (p246-7).
Some recent genetic studies have indeed suggested affinities between Ashkenazim and Armenian populations (Nebel et al 2001; Elhaik 2013).
“Weisbach‘s nineteen Jews vied with the Patagonians in possessing the longest nose (71 mm.) of all the nineteen races examined by him … while they had at the same time the narrowest noses (34 mim)” (Jacobs 1886).
This data, suggesting that Jewish noses are indeed long but are also very narrow, contradicts Baker’s claim that the characteristic Ashkenazi nose is “large in all dimensions [emphasis added]” (p239). However, such a nose shape is consistent Jews having evolved in an arid desert environment, such as the Nagev or other nearbydeserts, or in the Judean mountains, where the earliest distinctively Jewish settlements are thought to have developed. Thus, anthropologist Stephen Molnar writes:
Hans Eysenck refers in his autobiography to a study supposedly conducted by one of his PhD students that ostensibly demonstrated statistically that people, both Jewish and Gentile, actually perform at no better than chance when attempting to distinguish Jews from non-Jews, even after extended interaction with one another (Rebel with a Cause: p35). However, since he does not cite a source or reference for this study, it was presumably unpublished, and must be interpreted with caution. Eysenck himself, incidentally, was of closetedhalf-Jewish ancestry, practising what anti–SemiteKevinMacdonald calls ‘crypsis’, which may be taken to suggest he was not entirely disinterested with regard to to question of the extent to which Jews can be recognized by sight. The only other study I have found addressing the quite easily researchable, if politically incorrect, question of whether some people can or cannot identify Jews from non-Jews on the basis of phenotypic differences is Andrzejewski et al (2009).
 This is one of the few occasions in the book where I recall Baker actually mentioning whether the morphological differences between racial groupings that he describes are statistically significant.
 Interestingly, Stephen Oppenheimer, in his book Origins of the British, posits a link between the so-called ‘Celtic’ regions of the British Isles and populations from one particular area of the Mediterranean, namely the Iberian peninsula, especially the Basques, themselves probably the descendants of the original pre-Indo-European inhabitants of the peninsula (see Oppenheimer 2006; see also Blood of the Isles). This seemingly corroborates the otherwise implausible mythological account of the peopling of Ireland provided in Lebor Gabála Érenn, which claims that the last major migration to, and invasion of, Ireland, from which the modern Irish primarily descend, arrived from Spain in the form of the Milesians. This mythological account may derive from the similarity between the Greek and Latin words for the two regions, namely ‘Iberia’ and ‘Hibernia’ respectively, and between the words ‘Gael’ and ‘Galicia’, and the belief of some ancient Roman writers, notably Orosius and Tacitus, that Ireland lay midway between Britain and Spain (Carey 2001). However, while some early population genetic studies were indeed interpreted to suggest a connection between populations from Iberia and the British Isles, this interpretation has largely been discredited by more recent research.
On the other hand, the Welsh, in addition to being darker-haired than the English, are also darker-eyed, with a particularly high prevalence of dark eyes being found in certain more isolated regions of Wales (The Races of Europe: p389). Interestingly, as far back as the time of the Roman Empire, the Silures, a Brittonic tribe occupying most of South-East Wales and known for their fierce resistance to the Roman conquest, were described by Roman writers Tacitus and Jordanes (the Romans themselves being, of course, a Mediterranean people) as “swarthy” in appearance and as possessing black curly hair. The same is true of the, also until recently Celtic-speaking, Cornish people, who are, Coon reports, “the darkest eyed of the English” (The Races of Europe: p389). Dark hair is also more common in Cornwall(The Races of Europe: p386). Cornwall is, Coon therefore reports, “the darkest county in England” (The Races of Europe: p396). (However, with the historically unprecedented mass migration of non-whites into the UK in the latter half of the twentieth century and beyond, this is, of course, no doubt no longer true.) Yet another complicating factor is the prevalence of red hair, which is also associated with the ‘Celtic’ regions of the British Isles, but is hardly a Mediterranean character, and which, like dark hair, reaches its highest prevalence in Wales (The Races of Europe: p385). Baker, for his part, does not dwell on this point, but does acknowledge, “there is rather a high proportion of people with red hair in Wales”, something for which, he claims “no satisfactory explanation… has been provided” (p265). Interestingly, Baker is skeptical regarding the supposed association of the ancient Celts with ginger or auburn hair. He traces this belief to a single casual remark of Tacitus. However, he suggests that the Latin word used ‘rutilai’ is actually better translated as “red (inclining to golden yellow)”, and was, he observes, also used to refer to the Golden Fleece and to gold coinage (p257).
“We are an ancient people, and though the [British] Isles has been the target of invasion and opposed settlement from abroad ever since Julius Caesar first stepped onto the shingle shores of Kent, these have barely scratched the topsoil of our deep rooted ancestry” (Blood of the Isles: p338).
However, population genetics is an extremely fast moving science, and recent research has revised this conclusion, suggesting a replacement of around 90% of the population of the British Isles, albeit in very ancient times (around 2000BCE) associated with the spread of the Bell Beaker culture and Steppe-related ancestry, presumably deriving from the Indo-European expansion (Olalde et al 2018). Also, recent population genetic studies suggest that the Anglo-Saxons actually made a greater genetic contribution to the ancestry of the English, especially those from Eastern England, than formerly thought (e.g. Martiniano et al 2016; Schiffels et al 2016).
 However, in The Origins of the British, Stephen Oppenheimer proposes an alternative route of entry and point of initial disembarkation, suggesting that the people whom we today habitually refer to as ‘Celts’ arrived, not from Central Europe as traditionally thought, but rather up the Atlantic seaboard from the west coasts of France and Iberia. This is consistent with some archaeological evidence (e.g. the distribution of passage graves) suggesting longstanding trade and cultural links up the Atlantic seaboard from the Mediterranean region, through the Basque country, into Brittany, Cornwall, Wales and Ireland. This would also provide an explanation for what Baker claims is a ‘Mediterranid’ component in the ancestry of the Welsh and Irish, as supposedly evidenced in distribution of blood groups and the prevalence dark hair and eye colours as recorded by Beddoe.
“As brain tissue expanded… it did so at the expense of the temporalis muscles, which… close the jaw. Since smaller temporalis muscles cannot close as large a jaw, jaw size was reduced. Consequently, there is less room for teeth” (Race, Evolution and Behavior: Preface to Third Edition: p20-1).
 Actually, the meaning of the two terms is subtly different. ‘Paedomorphy’ refers to the retention of juvenile or infantile traits into adulthood. ‘Neoteny’ refers to one particular process whereby this end-result is achieved, namely slowing some aspects of physiological development. However, ‘paedomorphy’ can also result from another process, namely ‘progenesis’, where, instead, some aspects of development are actually sped up, such that the developing organism reaches sexual maturity earlier, before reaching full maturity in other respects. In humans, most examples of paedomorphy result from the former process, namely ‘neoteny’.
 These genitalia, of course, contrast with those of neighbouring Negroids, at least according to popular stereotype. For his part, Baker accepts the stereotype that black males have large penes. However, he cites no quantitative data, remarking only:
“That Negrids have large penes is somtimes questioned, but those who doubt it are likely to change their minds if they will look at photographs 8, 9, 20, 23, 29, and 37 in Bernatzig’s excellently illustrated book ‘Zwischen Weissem Nil und Belgisch-Kongo’. They represent naked male Nilotids and appear convincing” (p331).
But five photos, presumably representing just five males, hardly represents a convincing sample size. (I found several of the numbered pictures online by searching for the book’s title, and each showed only a single male.) Interestingly, Baker is rightly skeptical regarding claims of differences in the genitalia between European subraces, given the intimate nature of the measurements required, writing:
“It is difficult to obtain reliable measurements of theses parts of the body and statements about subracial differences in them must not be accepted without confirmation” (p219).
 Among the traits that have been associated with neotenty in humans are our brain size, growth patterns, hairlessness, inventiveness, upright posture, spinal curvature, smaller jaws and teeth, forward facing vaginas, lack of a penis bone, the length of our limbs and the retention of the hymen into adulthood.
 Baker does discuss the performance of East Asians on IQ tests, but his conclusions are ambivalent (p490-492). He concludes, for example, “the IQs of Mongolid[i.e. East Asian] children in North America are generally found to be about the same as those of Europids” (p490). Yet recent studies have revealed a slight advantage for East Asians in general intelligence. Baker also mentions the relatively higher scores of East Asians on tests ofspatio-visual ability,as compared to verbal ability.However, he attributes this to their lack of proficiency in the language of their host culture, as he relied mostly on American studies of first and second-generation immigrants, or the descendants of immigrants, who were often raised in non-English-speaking homes, and hence only learnt English as a second-language (p490). However, recent studies suggest that East Asians score relatively lower on verbal ability, as compared to their scores on spatio-visual ability, even when tested in a language in which they are wholly proficient (see Race Differences in Intelligence: reviewed here).
 Indeed, in proposing tenable environmental-geographical explanations for the rise and fall of civilizations in different parts of the world, Jared Diamond’s Guns, Germs and Steel represents a substantial challenge to Baker’s conclusions in this chapter and the two books are well worth reading together. Another recent work addressing the question of why civilizations rise and fall among different races and peoples, but reaching less politically-correct conclusions, is Michael Hart’s Understanding Human History, which seems to have been conceived of as a rejoinder to Diamond, drawing heavily upon, but also criticizing the former work.
 Interestingly, Baker quotes Toynbee as suggesting that:
“An ‘identifying mark’ (but not a definition) [of] civilization might be equated with ‘a state of society in which there is a minority of the population, however small, that is free from the task, nor merely of producing food, but of engaging in any other form of economic activities-e.g. industry or trade” (p508).
Yet a Marxist would view this, not as a marker of civilization, but rather of exploitation. Those free from engaging in economic activity are, from a Marxist perspective, clearly extracting surplus value, and hence exploiting the labour of others. Toynbee presumably had in mind the ‘idle rich’ or ‘leisure class’, as well perhaps as those whom the latter patronize, e.g. artists, though the latter, if paid for their work, are surely engaging in a form of economic activity, as indeed are the patrons who subsidize them. (Indeed, even the ‘idle rich’ or ‘leisure class’ engage in economic activity, if only as consumers.) However, this criterion, at least as described by Baker, is at least as capable of applying to the opposite end of the social spectrum – i.e. the welfare-dependent underclass. Did Toynbee really intend to suggest that the existence of the long-term unemployed is a distinctive marker of civilization? If so, is Baker really agreeing with him?
 The full list of criteria for civilization provided by Baker is as follows:
“In the ordinary circumstances of life in public places they cover the external genitalia and greater part of the trunk with clothes” (p507);
“They order their society by a system of laws, which are enforced in such a way that they ordinarily go about their various concerns in times of peace without danger of attack or arbitrary arrest” (p507);
“They permit accused people to defend themselves and call witnesses” (p507);
“They do not use torture to extract information or punishment” (p507);
“There is some appreciation of the fine arts” (p508);
“Knowledge and understanding are valued as ends in themselves” (p508).
 Actually, some of the criteria include both technological and moral elements. For example, the second requirement, namely that the culture in question “keep the body clean and take care to dispose of its waste elements”, at first seems a purely moral requirement. However, the disposal of sewage is, not only essential for the maintenance of healthy populations living at high levels of population density, but also often involves impressive feats of engineering (p507). Similarly, the requirement that some people “live intowns or cities” seems quite arbitrary. However, to sustain populations at the high population density required in towns and cities usually requires substantial technological, not to mention social and economic, development. Likewise, the building and maintenance ofroads linking these settlements, also mentioned by Baker as part of the same criterion, is a technological achievement, often requiring, like the building of facilities for sewage disposal, substantial coordination of labour.
“Until the arrival of Europeans there was no literate civilization in the continent’s black belt. The Negro had no written language, no numerals, no calendar, no system of measurement. He never developed a plow or wheel. He never domesticated any animal. With the rarest exceptions, he built nothing more elaborate than mud huts and thatched stockades” (IQ and Racial Differences: p2).
 This, of course, depends on precisely how we define the words ‘machine’ and ‘mechanical’. Thus, many authorities, especially military historians, class the simple bow as the first true ‘machine’. However, the only indigenous people known to lack even the bow and arrow at the time of their first contact with Europeans were the Australian Aboriginals of Australia and Tasmania.
 With regard to the ruins of Great Zimbabwe, Baker emphasizes that “the buildings in question are in no sense houses; the great majority of them are simply walls” (p402). Nor do they appear to have been part of a two-storey building (p402). Unlike some other racialist authors who have attributed their construction to the possiblypart-JewishLemba people, Baker attributes their construction and design to indigenous Africans (p405). However, he suggests their anomalous nature reflected that they had been constructed in (crude) imitation of buildings constructed outside of the “secluded area” of Africa by non-Negro peoples with whom the former were in a trading relationship (p407-8). This would explain why the structures, though impressive by the standards of other constructions within the “secluded zone” of Africa from the same time-period, where buildings of brick or stone were rare and tended to be on a much smaller scale (so impressive, indeed, that, in the years since Baker’s book was published, they have even had an entire surrounding country named after them), are, by European or Middle Eastern standards of the same time period, quite shoddy. Baker also emphasizes:
“The splendour and ostentation were made possible by what was poured into the country from foreign lands. One must acknowledge the administrative capacity of the rulers, but may question the utility of the ends to which much of it was put” (p409).
 Several plants seem to have been domesticated in the Sahel region, and the Horn of Africa, both of which are part of sub-Saharan Africa. However, these areas lie outside of what Baker calls the “secluded area”, as I understand it. Also, populations from the Horn of Africa are, according to Baker predominantly Caucasoid (p225).
 The sole domestic animal that was perhaps first domesticated by black Africans is the guineafowl. Guineafowl are found wild throughout sub-Saharan Africa, but not elsewhere. It has therefore been argued, plausibly enough, that it was first domesticated in sub-Saharan Africa. However, Baker reports that the nineteenth-century explorers whose work he relies on “nowhere mention its being kept as a domestic animal by Negrids” (p375). Instead, he proposes it was probably first domesticated in Ethiopia, outside the “secluded area” as defined by Baker, and whose population are, according to Baker, predominantly Caucasoid (p225). However, he admits that there are no “early record of tame guinea-fowl in Ethiopia” (p375).
 The relative absense of large wild mammals outside of sub-Saharan Afirca may partly be because such mammals have been driven to extinction or had their numbers depleted in recent times (e.g. wolves have been driven to extinction in Britain and Ireland, bison to the verge of extinction in North America). However, it is likely that Africa had a comparatively large number of large wild mammalian species even in ancient times. This is because outside of Africa (notably in the Americas), many wild mammals were wiped out by the sudden arrival of humans with their formidable hunting skills to whom indigenous fauna were wholly unadapted. However, Africa is where humans first evolved. Therefore, prey species will have gradually evolved fear and avoidance of humans at the same time as humans themselves first evolved to become formidable hunters. Thus, Africa, unlike other continents, never experienced a sudden influx of human hunters to whom its prey species were wholly unadapted. It therefore retains many of large wild game animals into modern times.
 Of course, rather conveniently for Diamond’s theory, the wild ancestors of many modern domesticated animals, including horses and aurochs, are now extinct, so we have no way of directly assessing their temperament. However, we have every reason to believe that aurochs, at least, posed a far more formidable obstacle to domestication than does the zebra.
 Actually, a currently popular theory of the domestication of wolves/dogs holds that humans did not so much domesticate wolves/dogs as wolves/dogs domesticated themselves.
Aurochs, and contemporary domestic cattle, also evince another trait that, according to Diamond, precludes their domestication – namely, it is not usually possible to keep two adult males of this species in the same field enclosure. Yet, according to Diamond, the “social antelope species for which Africa is famous” could not be domesticated because:
“The males of [African antelope] herds space themselves into territories and fight fiercely with one another when breeding. Hence, those antelope cannot be maintained in crowded enclosures in captivity” (Guns, Germs and Steel: p174).
Evidently, the ancient Eurasians who successfully domesticated the auroch never got around to reading Diamond’s critially acclaimed bestseller. If they had, they could have learnt in advance to abandon the project as hopeless and hence save themselves the time and effort.
“More study has been devoted to the craniology of ancient Egypt than to that of any other country in the world” (p517).
From such data, Baker reports:
“Morant showed that all the sets of ancient Egyptian skills that he analysed statistically were distinguishable by each of six criteria from Negrid skulls” (p518).
For what it’s worth, this conclusion is also corroborated by their self-depiction in artwork:
“In their monuments the dynastic Egyptians represented themselves as having a long face, pointed chin with scanty beard, a straight or somewhat aquiline nose, black irises, and a reddish-brown complexion” (p518).
“It was a common artistic style in many ancient Mediterranean cultures to portray men with red skins and women with white skins. This was done, presumably to reflect the fact that the men would have been outside working in the fields” (Children of Ra: p33).
Actually, according to anthropologist Peter Frost, this artistic convention reflects real and innate differences, as well as differing sexually selected ideals of male and female beauty (see Dark Men, Fair Women). Most interestingly, Kemp also includes photographs of some Egyptian mummies, including Ramses II, apparently with light-coloured hair. At first, I suspected this might reflect loss of pigmentation owing to the process of decay occurring after death, or perhaps to some chemical process involved in mummification. Robert Brier, an expert on mummification, confirms that Ramses’s “strikingly blond” hair was indeed a consequence of its having been “dyed as a final step in the mummification process so that he would be young forever” (The Encyclopedia of Mummies: p153). However, he also reports in the next sentence that:
“It would appear that their head-hair was curly, wavy, or almost straight, and very dark brown or black” (p518).
This conclusion is again based on the evidence of their mummies, and, since mummification was a costly procedure largely restricted to the wealthy, it again contradicts Kemp’s notion of a ‘Nordic elite’ ruling ancient Egypt. On this and other evidence, Baker therefore concludes:
“There is general agreement… that the Europid element in the Egyptians from predynastic times onwards has been primarily Mediterranid, though it is allowed that Orientalid immigrants from Arabia made a contribution to the stock” (p518).
Writing appears to have been developed first in Mesopotamia, then shortly afterwards in Egypt (though some Egyptologists claim priority on behalf of Egypt). However the relative geographic proximity of these two civilizations, their degree of contact with one anther and the coincidence in time, make it likely that one writing system was copied from the other. It then seems to have been independently developed in China. Writing was also developed, almost certainly entirely independently, in Mesoamerica. Other possible candidates for the independent development of writing include the Indus Valley civilization, and Easter Island, though, since neither script has been deciphered, it is not clear that they represent true writing systems, and the Easter Island script has also yet to be reliably dated.
Actually, it is now suggested that both the Mayans and Indians may have been beaten to this innovation by the Babylonians, although, unlike the later Indians and Muslims, neither the Mayans nor the Babylonians went on to take full advantage of this innovation, by developing mathematics in a way made possible by their innovation. For this, it is Indian civilization that deserves credit. The invention of the concept by both the Maya and the Babylonians was, of course, entirely independent of one another, but the Indians, the Islamic civilization and other Eurasian civilizations probably inherited the concept ultimately from Babylonia.
Interestingly, this excuse is not available in Africa. There, large mammals survived, probably because, since Africa was where anatomically modern humans first evolved, prey species evolved in concert with humans, and hence gradually evolved to fear and avoid humans, at the same time as humans themselves gradually evolved to be formidable predators. In contrast, the native species of the Americas would have been totally unprepared to protect themselves from human hunters, to whom they were completely ill-adapted, owing to the late, and, in evolutionary terms, sudden, peopling of the continent. This may be why, to this day, Africa has more large animals than any other continent.
 Baker also uses the complexity of a people’s language in order to assess their intelligence. Today, there seems to be an implicit assumption among many linguists that all languages are equal in their complexity. Thus, American linguists rightly emphasize the subtlety and complexity of, for example, African-American vernacular, which is certainly, by no means, merely a impoverished or corrupted version of standard English, but rather has grammatical rules all of its own, which often convey information that is lost on white Americans not conversant in this dialect. However, there is no a priori reason to assume that all languages are equal in their capacity to express complex and abstract ideas. The size of vocabularies, for example, differs in different languages, as does the number of different tenses that are recognised. For example, the Walpiri language of some Australian Aboriginals is said to have only a few number terms, namely words for just ‘one’ ‘two’ and ‘many’, while the Pirahã language of indigenous South Americans is said to get by with no number terms at all. Thus, Baker contends that certain languages, notably the Arunta language of indigenous Australians, as studied by Alf Sommerfelt, and also the Akan language of Africa, are inherently impoverished in their capacity to express abstract thought. He may well be right.
Thus, despite its subtitle, “An Evolutionary Analysis”, the focus is very much on documenting the existence of race differences in intelligence, not explaining how or why they evolved. The “Evolutionary Analysis” promised in the subtitle is actually almost entirely confined to the last three chapters.
The choice of this as a subtitle is therefore misleading and presumably represents an attempt to cash in on the recent rise in, and popularity of, evolutionary psychology and other sociobiological explanations for human behaviours.
However, whatever the inadequacies of Lynn’s theory of how and why race differences in intelligence evolved (discussed below), his documentation of the existenceof these differences is indeed persuasive. The sheer number of studies and the relative consistency over time and place suggests that the differences are indeed real and there is therefore something to be explained in the first place.
In this respect, it aims to do something similar to what was achieved by Audrey Shuey’s The Testing of Negro Intelligence, first published in 1958, which brought together a huge number of studies, and a huge amount of data, regarding the black-white test score gap in the US.
However, whereas Shuey focused almost exclusively on the black-white test score gap in North America, Lynn’s ambition is much broader and more ambitious – namely, to review data relating to the intelligences of all racial groups everywhere across the earth.
Thus, Lynn declares that:
“The objective of this book [is] to broaden the debate from the local problem of the genetic and environmental contributions to the difference between whites and blacks in the United States to the much larger problem of the determinants of the global differences between the ten races whose IQs are summarised” (p182).
Therefore, his book purports to be:
“The first fully comprehensive review… of the evidence on race differences in intelligence worldwide” (p2).
Consistent with this, Lynn includes in his analysis data for many racial groups that rarely receive much if any coverage in previous works on the topic of race differences in intelligence.
The average IQs reported by Lynn are, he informs us, corrected for the Flynn Effect – i.e. the rise in IQs over the last century (p5-6).
However, the Flynn Effect has occurred at different rates in different regions of the world. Likewise, the various environmental factors that have been proposed as possible explanations for the phenomenon (e.g. improved nutrition and health as well as increases in test familiarity, and exposure to visual media) have varied in the extent to which they are present in different places. Correcting for the Flynn Effect is therefore easier said than done.
IQs of “Hybrid populations”
Lynn also discusses the average IQs of racially-mixed populations, which are, he reports, consistently intermediate between the average IQs of the two (or more) parent populations.
Finally, Lynn also purports to estimate what he calls the “genotypic IQ” of at least some of the races discussed. This is a measure of genetic potential, distinguished from their actual realized phenotypic IQ.
He defines the “genotypic IQ” of a population as the average score of a population if they were raised in environments identical to those of the group with whom they are being compared.
Thus, he writes:
“The genotypic African IQ… is the IQ that Africans would have if they were raised in the same environment as Europeans” (p69).
The fact that lower-IQ groups generally provide their offspring with inferior environmental conditions is therefore irrelevant for determining their “genotypic IQ”. However, as Lynn himself later points out:
“It is problematical whether the poor nutrition and health that impair the intelligence of many third world peoples should be regarded as a purely environmental effect or as to some degree a genetic effect arising from the low intelligence of the populations that makes them unable to provide good nutrition and health for their children” (p193).
Also, Lynn does not explain why he uses Europeans as his comparison group – i.e. why the African genotypic IQ is “the IQ that Africans would have if they were raised in the same environment as Europeans”, as opposed to, say, if they were raised in the same environments East Asians, Middle Eastern populations or indeed their own environments.
Presumably this reflects historical reasons – namely, Europeans were the first racial group to have their IQs systematically measured – the same reason that European IQs are arbitrarily assigned an average score of 100.
Reaction times refer to the time taken to perform so-called elementary cognitive tasks. These are tests where everyone can easily work out the right answer, but where the speed with which different people get there correlates with IQ.
Arthur Jensen has championed reaction time as a (relatively more) direct measure of one key cognitive process underlying IQ, namely speed of mental processing.
Yet individuals with quicker reaction times would presumably have an advantage in sports, since reacting to, say, the speed and trajectory of a ball in order to strike or catch it is analogous to an elementary cognitive task.
However, despite lower IQs, African-Americans, and blacks resident in other western economies, are vastly overrepresented among elite athletes.
To explain this paradox, Lynn distinguishes “reaction time proper” – i.e. when one begins to move one’s hand towards the correct button to press – from “movement time” – how long one’s hand takes to get there.
Whereas whites generally react faster, Lynn reports that blacks have faster movement times (p58-9). Thus, Lynn concludes:
“The faster movement times of Africans may be a factor in the fast sprinting speed of Africans shown in Olympic records” (p58).
As between species, brain-size is also thought to correlate with intelligence, at least after controlling for body-size.
Indeed, since brain tissue is highlymetabolically expensive, increases in brain-size would surely never have evolved with conferring some countervailing selective advantage.
Thus, in the late-1960s, biologist HJ Jerison developed an equation to estimate an animal’s intelligence from its brain- and body-size alone. This is called the animal’s encephalization quotient.
However, comparing the intelligence of different species poses great difficulties.
In short, if you think a ‘culture fair’ IQ test is an impossibility, then try designing a ‘species fair’ test!
Moreover, dwarves have smaller absolute brain-sizes but usually larger brains relative to body-size, but usually have normal IQs.
Sex differences in IQ, meanwhile, are smaller than those between races even though differences in brain-size are greater, at least before one introduces controls for body-size.
Also, Neanderthals had larger brains than modern humans, despite a shorter, albeit more robust, stature.
One theory has it that population differences in brain-size reflect a climatic adaptation that evolved in order to regulate temperature, in accordance with Bermann’s Rule. This seems to be the dominant view among contemporary biological anthropologists, at least those who deign (or dare) to even discuss this politically charged topic.
Thus, in one recent undergraduate textbook in biological anthropology, authors Mielke, Konigsberg and Relethford contend:
“Larger and relatively broader skulls lose less heat and are adaptive in cold climates; small and relatively narrower skulls lose more heat and are adaptive in hot climates” (Human Biological Variation: p285).
On this view, head size and shape represents a means of regulating the relative ratio of surface-area-to-volume, since this determines the proportion of a body that is directly exposed to the elements.
Thus, Stephen Molnar, the author of another competing undergraduate textbook in biological anthropology, observes
This then might explain why, despite the relatively primitive state of their pre-contact civilization and not especially high IQ scores (see below), those whom Lynn terms “Artic Peoples” (i.e. Eskimos) have, according to Lynn’s data, the largest brains of any of the racial groups whom he discusses.
The Bermann–Allen rules likely also explain at least some of the variation in body-size and stature as between racial groups.
For example, Eskimos tend to be short and stocky, with short arms and legs and flat faces. This minimizes the ratio of surface-area-to-volume, ensures only a minimal proportion of the body is directly exposed to the elements, and also minimizes the extent of extremities (e.g. arms, legs, noses), which are especially vulnerable to the cold.
In contrast, populations from tropical climates, such as African blacks and Australian Aboriginals, tend to have relatively long arms and legs as compared to trunk size, a factor which likely contributes towards their success in some athletic events.
At any rate, it is surely implausible that an increase in brain tissue, which is metabolicallyhighly expensive, would have evolved solely for the purpose of regulating temperature, when the same result could surely have been achieved by modifying only the external shape of the skull.
Conversely, even if race differences in brain-size did evolve purely for temperature regulation, differences in intelligence could still have emerged as a by-product of such selection.
In other words, if larger brains did evolve among populations inhabiting colder latitudes solely for the purposes of temperature regulation, the extra brain tissue that resulted may still have resulted in greater levels of cognitive ability among these populations, even if there was no direct selection for increased cognitive ability itself.
The first racial group discussed by Lynn are those he terms “Europeans” (i.e. white Caucasians). He reviews data on IQ both in Europe and among diaspora populations elsewhere in the world (e.g. North America, Australia).
The results are consistent, almost always giving an average IQ of about 100 – though this figure is, of course, arbitrary and reflects the fact that IQ tests were first normed by reference to European populations. This is what James Thompson refers to as the ‘Greenwich mean IQ’ and the IQs of all other populations in Lynn’s book are calculated by reference to this figure.
Southeast Europeans, however, score slightly lower. This, Lynn argues, is because:
“Balkan peoples are a hybrid population or cline, comprising a genetic mix between the Europeans and South Asians in Turkey” (p18).
Therefore, as a hybrid population, their IQs are intermediate between those of the two parent populations, and, according to Lynn, South Asians score somewhat lower in IQ than do white European populations (see below). Similarly, the Turkish people, being intermixed with Europeans, score slightly higher than other Middle-Eastern populations (p80).
In the newer 2015 edition, Lynn argues that IQs are somewhat lower elsewhere in southern Europe, namely southern Spain and Italy, for much the same reason, namely because:
“The populations of these regions are a genetic mix of European people with those from the Near East and North Africa, with the result that their IQs are intermediate between the parent populations” (Preface, 2015 Edition).
An alternative explanation is that these regions (e.g. Balkan countries, Southern Italy) have lower living-standards.
However, instead of viewing differences in living standards as causing differences in recorded IQs as between populations, Lynn argues that differences in innate ability themselves cause differences in living standards, because, according to Lynn, more intelligent populations are better able to achieve high levels of economic development (see IQ and the Wealth of Nations).
Moreover, Lynn observes that in Eastern Europe, living standards are substantially below elsewhere in Europe as a consequence of the legacy of communism. However, populations from Eastern Europe score only slightly below those from elsewhere in Europe, suggesting that even substantial differences in living-standards may have only a minor impact on IQ (p20).
The Portuguese also, Lynn claims, score lower than elsewhere in Europe.
However, he cites just two studies. These give average IQs of 101 and 88 respectively, which Lynn averages to give an average of 94.5 (p19).
Yet these two results are actually highly divergent, the former being slightly higher than the average for north-west Europe. This suggests an inadequate basis on which to posit a genetic difference in ability.
However, Lynn provocatively concludes:
“Intelligence in Portugal has been depressed by the admixture of sub-Saharan Africans. Portugal was the only European country to import black slaves from the fifteenth century onwards” (p19).
This echoes Arthur De Gobineau’s infamous theory that empires decline because, through their empires, they conquer large numbers of inferior peoples, who then inevitably interbreed with their conquerors, which, according to De Gobineau, results in the dilution the very qualities that permitted their imperial glories in the first place.
In support of Lynn’s theory, mitochondrial DNA studies have indeed found higher frequency of sub-Saharan African Haplogroup L in Portugal than elsewhere in Europe (e.g. Pereira et al 2005).
Ireland and ‘Selective Migration’
IQs are also, Lynn reports, somewhat lower than elsewhere in Europe in Ireland.
Lynn cites four studies of Irish IQs which give average scores of 87, 97, 93 and 91 respectively. Again, these are rather divergent but nevertheless consistently below the European average, all but one substantially so.
Of course, in England, in less politically correct times, the supposed stupidity of the Irish was once a staple of popular humour, Irish jokes being the English equivalent of Polish jokes in America.
However, the low IQ scores reported for Ireland seem anomalous given the higher average IQs recorded elsewhere in North-West Europe, especially the UK, Ireland’s next-door neighbour, whose populations are closely related to those in Ireland.
Moreover, although head size is obviously a crude, indirect measure of brain size, it is perhaps worth observing that Carleton Coon reported in 1939 that Ireland has “the largest heads of any country excepting Belgium”, head-size being especially large in the southwestern half of Ireland (The Races of Europe: p265). Thus, Coon reports that overall:
“Ireland consistently has the largest head size of any equal land area in Europe” (The Races of Europe: p377).
Of course, historically Ireland was, until relatively recently, quite poor by European standards.
It is also sparsely populated and a relatively high proportion of the population live in rural areas, and there is some evidence that people from ruralareas have lower average IQs than those from urbanareas.
Moreover, although formerly Ireland was much poorer, the studies cited by Lynn were published from 1973 to 1993, yet show no obvious increase over time.
Lynn himself attributes the depressed Irish IQ to what he calls ‘selective migration’, claiming:
“There has been some tendency for the more intelligent to migrate, leaving less intelligent behind” (p19).
Of course, this would suggest, not only that the remaining Irish would have lower average IQs, but also that the descendants of Irish émigrés in Britain, Australia, America and other diaspora communities would have relatively higher IQs than other white people.
It certainly seems plausible that migrants differ in personality from those who choose to remain at home. It is likely that they are braver, have greater determination, drive and willpower than those who choose to stay behind. They may also perhaps be less ethnocentric, and more tolerant of foreign cultures.
However, I see no obvious reason they would differ in intelligence.
As Chanda Chisala writes:
“Realizing that life is better in a very rich country than in your poor country is never exactly the most g-loaded epiphany among Africans” (Chisala 2015b).
Likewise, it likely didn’t take much brain-power for Irish people to realize during the Irish Potato Famine that they were less likely to starve to death if they emigrated abroad.
Of course, wealth is correlated with intelligence and may affect the decision to migrate.
The rich usually have little economic incentive to migrate, while the poor may be unable to afford the often-substantial costs of migration (e.g. transportation).
However, without actual historical data showing certain socioeconomic classes or intellectual ability groups were more likely to migrate than others, Lynn’s claims regarding ‘selective migration’ represent little more than a post-hoc rationalization for IQ differences that are otherwise anomalous and not easily explicable in terms of heredity.
Ireland, Catholicism and Celibacy
Interestingly, in the 2015 edition of ‘Race Differences in Intelligence’, Lynn also proposes, in addition, a further explanation for the low IQs supposedly found in Ireland, namely the clerical celibacy demanded under Catholicism. Thus, Lynn argues:
However, it is perhaps arguable that, in an earlier age, when religious dogmas were relentlessly enforced, religious scholarship may have been the only form of intellectual endeavour that it was safe for intellectually-minded people to engage in.
Anyone investigating more substantial matters, such as whether the earth revolved around the sun or vice versa, was liable to be burnt at the stake if he reached the wrong (i.e. the right) conclusion.
Yet there is little if any evidence of depressed IQs in, say, France or Austria, although the populaions of both these countries were, until recently, like that of Ireland, predominantly Catholic.
The next chapter is titled “Africans”. However, Lynn uses this term to refer specifically to black Africans – i.e. those formerly termed ‘Negroes’. He therefore excludes from this chapter, not only the predominantly ‘Caucasoid’ populations of North Africa, but also African Pygmies and the Khoisan of southern Africa, who are considered separately in a chapter of their own.
Lynn’s previous estimate of the average sub-Saharan African IQ as just 70 provoked widespread incredulity and much criticism. However, undeterred, Lynn now goes even further, estimating the average African IQ even lower, at just 67.
Curiously, according to Lynn’s data, populations from the Horn of Africa (e.g. Ethiopia and Somalia) have IQs no higher than populations elsewhere in sub-Saharan Africa.
Yet populations from the Horn of Africa are known to be partly, if not predominantly, Caucasoid in ancestry, having substantial genetic affinities with populations from the Middle East..
Therefore, just as populations from Southern Europe have lower average IQs than other Europeans because, according to Lynn, they are genetically intermediate between Europeans and Middle Eastern populations, so populations from the Horn of Africa should score higher than those from elsewhere in sub-Saharan Africa because of intermixture with Middle Eastern populations.
However, Lynn’s data gives average IQs for Ethiopia and Somalia of just 68 and 69 respectively – no higher than elsewhere in sub-Saharan Africa (The Intelligence of Nations: p87; p141-2).
On the other hand, blacks resident in western economies score rather higher, with average IQs around 85.
The only exception, strangely, are the Beta Israel, who also hail from the Horn of Africa, but are now mostly resident in Israel, yet who score no higher than those blacks still resident in Africa. From this, Lynn concludes:
“These results suggest that education in western schools does not benefit the African IQ” (p53).
However, why then do blacks resident in other western economies score higher? Are blacks in Israel somehow treated differently than those resident in the UK, USA or France?
For his part, Lynn attributes the higher scores of blacks resident in these other Western economies to both superior economic conditions and, more controversially, to racial admixture.
Thus, African-Americans in particular are known to be a racially-mixed population, with substantial European ancestry (usually estimated at around 20%) in addition to their African ancestry.
Therefore, Lynn argues that the higher IQs of African-Americans reflect, in part, the effect of the European portion of their ancestry.
In addressing this perceived paradox, Lynn reviews the results of various psychometric measures of musical ability. These tests include:
Recognizing a change in pitch;
Remembering a tune;
Identifying the constituent notes in a chord; and
Recognizing whether different songs have similar rhythm (p55).
In relation to these sorts of tests, Lynn reports that African-Americans actually score somewhat lower in most elements of musical intelligence than do whites, and their musical ability is indeed generally commensurate with their general low IQs.
However, even with respect to rhythmical ability, blacks score no higher than whites. Instead, blacks’ scores on measures of rhythmical ability are exceptional only in that this is the only form of musical ability on which blacks score equal to, but no higher than, whites (p56).
For Lynn, the low scores of African-Americans in psychometric tests of musical ability are, on further reflection, little surprise.
“The low musical abilities of Africans… are consistent with their generally poor achievements in classical music. There are no African composers, conductors, or instrumentalists of the first rank and it is rare to see African players in the leading symphony orchestras” (p57).
However, who qualifies as a composer, conductor or instrumentalist “of the first rank” is, ultimately, unlike the results of psychometric testing, a subjective assessment, as are all artistic judgements.
Moreover, why is achievement in classical music, an obviously distinctly western genre of music, to be taken as the sole measure of musical accomplishment?
Even if we concede that the ability required to compose and perform classical music is greater than that required for other genres (e.g. jazz and popular music), musical intelligence surely facilitates composition and performance in other genres too – and, given the financial rewards offered by popular music often dwarf those enjoyed by players and composers of classical music, the more musically-gifted race would have every incentive to dominate this field too.
Perhaps, then, these psychometric measures fail to capture some key element of musical ability relevant to musical accomplishment, especially in genres other than classical.
In this context, it is notable that no lesser champion of standardized testing than Arthur Jensen has himself acknowledged that intelligence tests are incapable of measuring creativity (Langan & LoSasso 2002: p24-5).
“Blacks have certain inherited abilities, such as improvisational decision making, that could explain why they predominate in… jazz, rap and basketball” (The End of Racism: p440-1).
Steve Sailer rather less tentatively expands upon this theme, positing an African advantage in:
“Creative improvisation and on-the-fly interpersonal decision-making” (Sailer 1996).
On this basis, Sailer concludes that:
“Beyond basketball, these black cerebral superiorities in ‘real time’ responsiveness also contribute to black dominance in jazz, running with the football, rap, dance, trash talking, preaching, and oratory” (Sailer 1996).
“Bushmen and Pygmies”
Grouped together as the subjects of the next chapter are black Africans’ sub-Saharan African neighbours, namely San Bushmen and Pygmies.
Quite why these two populations are grouped together by Lynn in a single chapter is unclear.
“These two peoples have distinctive but closely related genetic characteristics and form two related clusters” (p73).
However, although both groups are obviously indigenous to sub-Saharan Africa and quite morphologically distinct from the other black African populations who today represent the great majority of the population of sub-Saharan Africa, they share no especial morphological similarity to one another.
Moreover, since Lynn acknowledges that they have “distinctive… genetic characteristics and form two… clusters”, they presumably should each of merited chapters of their own.
One therefore suspects that they are lumped together more for convenience than on legitimate taxonomic grounds.
In short, both are marginal groups of hunter-gatherers, now few in number, few if any of whom have been exposed to the sort of standardized testing necessary to provide a useful estimate of their average IQs. Therefore, since his data on neither group alone is really sufficient to justify its own chapter, he groups them together in a single chapter.
However, the lack of data on IQ for either group means that even this combined chapter remains one of the shorter chapters in Lynn’s book, and, as we will see, the paucity of reliable data on the cognitive ability of either group leads one to suspect that Lynn might have been better omitting both groups from his survey of race differences in cognitive ability altogether, just as he omitted at least one other phenotypically quote distinct racial group for whom presumably there is again little data on IQs, namely the Negrito populations of South and South-East Asia.
It may be some meagre consolation to African blacks that, at least in Lynn’s telling, they no longer qualify as the lowest scoring racial group when it comes to IQ. Instead, this dubious honour is now accorded their sub-Saharan African neighbours, San Bushmen.
“All of us have the impression that Bushmen are really quick and clever and are quite different from their [Bantu] neighbors… Bushmen don’t look like their black African neighbors either. I expect that there will soon be real data from the Namibian school system about the relative performance of Bushmen… and Bantu kids – or more likely, they will suppress it” (Race: The Reality of Human Differences (reviewed here): p227).
Today, however, some fifteen or so years after Sarich and Miele published this quotation, the only such data I am aware of is that reported by Lynn in this book, which suggests, at least according to Lynn, a level of intelligence even lower than that of other sub-Saharan Africans.
Unfortunately, however, the data in question is very limited and, in my view, inadequate to support Lynn’s controversial conclusions regarding Bushman ability.
It also consists of just three studies, none of which remotely resemble a full IQ test (p74-5).
Yet, from this meagre dataset, Lynn does not hesitate to attribute to Bushmen an average IQ of just 52.
If Lynn’s estimate of the average sub-Saharan African IQ at around 70 provoked widespread incredulity, then his much lower estimate for Bushmen is unlikely to fare better.
Lynn anticipates such a reaction, and responds by pointing out:
“An IQ of 54 represents the mental age of the average European 8-year-old, and the average European 8-year-old can read, write, and do arithmetic and would have no difficulty in learning and performing the activities of gathering foods and hunting carried out by the San Bushmen. An average 8-year-old can easily be taught to pick berries put them in a container and carry them home, collect ostrich eggs and use the shells for storing water and learn how to use a bow and arrow” (p76).
Indeed, Lynn continues, other non-human animals survive in difficult, challenging environments with even lower levels of intelligence:
“Apes with mental abilities about the same as those of human 4-year olds survive quite well as gatherers and occasional hunters and so also did early hominids with IQs around 40 and brain sizes much smaller than those of modern Bushmen. For these reasons there is nothing puzzling about contemporary Bushmen with average IQs of about 54” (p77).
Here, Lynn makes an important point. Many non-human animals survive and prosper in ecologically challenging environments with levels of intelligence much lower than that of any hominid, let alone any extant human race.
On the other hand, however, I suspect Lynn would not last long in Kalahari Desert – the home environment of most contemporary Bushmen.
Lynn’s data on the IQs of Pygmies is even more inadequate than his data for Bushmen. Indeed, it amounts to just one study, which again fell far short of a full IQ test.
Moreover, the author of the study, Lynn reports, did not quantify his results, reporting only that Pygmies scored much “much worse” than other populations tested using the same test (p78).
However, while the other populations tested using the same test and outperforming Pygmies included “Eskimos, Native American and Filipinos”, Lynn conspicuously does not mention that they included other black Africans, or indeed other very low IQ groups such as Australian Aboriginals (p78).
Thus, Lynn’s assumption that Pygmies are lower in cognitive ability than other black Africans is not supported even by the single study that he cites.
Lynn also infers a low level of intelligence for Pygmies from their lifestyle and mode of sustenance:
“Most of them still retain a primitive hunter-gatherer existence while many of the Negroid Africans became farmers over the last few hundred years” (p78).
Thus, Lynn assumes that whether a population has successfully transitioned to agriculture is largely a product of their intelligence (p191).
In contrast, most historians and anthropologists would emphasize the importance of environmental factors in explaining whether a group transitions to agriculture.
Finally, Lynn also infers a low IQ from the widespread enslavement of Pygmies by neighbouring Bantus:
“The enslavement of Pygmies by Negroid Africans is consistent with the general principle that the more intelligent races generally defeat and enslave the less intelligent, just as Europeans and South Asians have frequently enslaved Africans but not vice versa” (p78).
However, while it may be a “general principle that the more intelligent races typically defeat and enslave the less intelligent” (p78), this is hardly a rigid rule.
After all, Arabs often enslaved Europeans. Yet, according to Lynn, the Arabs belong to a rather less intelligent race than do the Europeans whom they so often enslaved.
Interestingly, it is notable that Pygmies are the only racial group whom Lynn includes in his survey for whom he does not provide an actual figure as an estimate their average IQ, which presumably reflects a tacit admission of the inadequacy of the available data.
Curiously, unlike for all the other racial groups discussed, Lynn also fails to provide any data on Pygmy brain-size.
Presumably, Pygmies have small brains as compared to other races, if only on account of their smaller body-size – but what about their brain-size relative to body-size? Is there simply no data available?
Another group who are barely mentioned at all in most previous discussions of the topic of race differences in intelligence are Australian Aborigines. Here, however, unlike for Bushmen and Pygmies, data from Australian schools are actually surprisingly abundant.
These give, Lynn reports, an average Aboriginal IQ of just 62 (p104).
Unlike his estimates for Bushmen and Pygmies, this figure seems to be reliable, given the number of studies cited and the consistency of their results. One might say, then, that Australian Aboriginals have the lowest recorded IQs of any human race for whom reliable data is available.
Interestingly, in addition to his data on IQ, Lynn also reports the results of Piagetian measures of development conducted among Aboriginals. He reports, rather remarkably, that a large minority of Aboriginal adults fail to reach what Piaget called the concrete operational stage of development – or, more specifically, fail to recognize a substance, transferred to a new container, necessarily remains of the same quantity (p105-7).
Perhaps even more remarkable, however, are reports of Aborigine spatial memory (p107-8). This refers to the ability to remember the location of objects, and their locations relative to one another.
Thus, he reports, one study found that, despite their low general cognitive ability, Aborigines nevertheless score much higher than Europeans in tests of spatial memory (Kearins 1981).
Another study found no difference in the performance of whites and Aborigines (Drinkwater 1975). However, since Aborigines have much lower IQs overall, even equal performance on spatial memory as against Europeans is still out of sync with the performance of whites and Aborigines on other types of intelligence test (p108).
Lynn speculates that Aboriginal spatial memory may represent an adaptation to facilitate navigation in a desert environment with few available landmarks.
The difference, Lynn argues, seems to be innate, since it was found even among Aborigines who had been living in an urban environment (i.e. not a desert) for several generations (p108; but see Kearins 1986).
Two other studies reported lower scores than for Europeans. However, one was an unpublished dissertation and hence must be treated with caution, while the and the other (Knapp & Seagrim 1981) “did not present his data in such a way that the magnitude of the white advantage can be calculated” (p108).
“In mental ability New Guineans are probably genetically superior to Westerners, and they surely are superior in escaping the devastating developmental disadvantages under which most children in industrialized societies grow up” (Guns, Germs and Steel: p21).
Diamond bases this claim on the fact that, in the West, survival, throughout most of our recent history, depended on who was struck down by disease, which was largely random.
In contrast, in New Guinea, he argues, people had to survive on their wits, with survival depending on one’s ability to procure food and avoid homicide, activities in which intelligence was likely to be at a premium (Guns, Germs and Steel: p20-21).
He also argues that the intelligence of western children is likely reduced because they spend too much time watching television and movies (Guns, Germs and Steel: p21).
However, there is no evidence television has a negative impact on children’s cognitive development. Indeed, given the rise in IQs over the twentieth century has been concomitant with increases in television viewing, it has even been speculated that increasingly stimulating visual media may have contributed to rising IQs.
On the basis of two IQ studies, plus three studies of Piagetian development, Lynn concludes that the average IQ of indigenous New Guineans is just 62 (p112-3).
This is, of course, exactly the same as his estimate for the average IQ of Australian Aboriginals.
It is therefore consistent with Lynn’s racial taxonomy, since, citing Cavalli-Sforza et al, he classes New Guineans as in the same genetic cluster, and hence as part of the same race as Australian Aboriginals (p101).
They also, Lynn reports, score rather higher in IQ, with most such populations having average IQs of about 85 (p117). However, the Māoris of New Zealand score rather higher, with an average IQ of about 90 (p116).
Hawaiians and Hybrid Vigor
For the descendants of the inhabitants of one particular Pacific Island, namely Hawaii, Lynn also reports data regarding the IQs of racially-mixed individuals, both those of part-Native-Hawiian and part-East Asian ancestry, and those of part-Native-Hawiian and part-European ancestry.
These racial hybrids, as expected, score on average between the average scores for the two parent populations. However, Lynn reports:
“The IQs of the two hybrid groups are slightly higher than the average of the two parent races. The average IQ of the Europeans and Hawaiians is 90.5, while the IQ of the children is 93. Similarly, the average IQ of the Chinese and Hawaiians is 90, while the IQ of the children is 91. The slightly higher than expected IQs of the children of the mixed race parents may be a hybrid vigor or heterosis effect” (p118).
Actually, the difference between the “expected IQs” and the IQs actually recorded for the hybrid groups is so small (only one point for the Chinese-Hawaiians), that it could easily be dismissed as mere noise, and I doubt it would reach statistical significance.
Nevertheless, Lynn’s discussion begs the question as to why hybrid vigor has not similarly elevated the IQs of the other hybrid, or racially-mixed, populations discussed in other chapters, and why Lynn has not discussed this issue when reporting the average IQs of other racially-mixed populations in other chapters.
Presumably, then, which of these countervailing effects outweighs the other for different types of hybrid depends on the degree of genetic distance between the two parent populations. This, of course, varies for different races.
It is therefore possible that some racial mixes may tend to elevate intelligence, whereas others, especially between more distantly-related populations, may tend, on average, to depress intelligence.
For what it’s worth, Pacific Islanders, including Hawiians, are thought to be genetically closer to East Asians than to Europeans.
“South Asians and North Africans”
Another group rarely treated separately in earlier works are those whom Lynn terms “South Asians and North Africans”, though this group also includes populations from the Middle East.
Physical anthropologists often lumped these peoples together with Europeans as collectively “Caucasian” or “Caucasoid”. However, while acknowledging that they are “closely related to the Europeans”, Lynn cites Cavalli-Sforza et al as showing they form “a distinctive genetic cluster” (p79).
He also reports that they score substantially lower in IQ than do Europeans. Their average IQ in their native homelands is just 84 (p80), while South Asians resident in the UK score only slightly higher with an average IQ of just 89 (p82-4).
This conclusion is surely surprising and should, in my opinion, be treated with caution.
For one thing, all of the earliest known human civilizations – namely, Mesopotamia, Egypt and the Indus Valley civilization – surely emerged among these peoples, or at least in regions today inhabited primarily by people of this race.
Interestingly, in this light, one study cited by Lynn showed a massive gain of 14-points for children from India who had been resident in the UK for more than four years as compared to those who had been resident for less than four years, the former scoring almost as high in IQ as the indigenous British, with an average IQ of 97 (p83-4; Mackintosh & Mascie-Taylor 1985).
In the light of this study, it would be interesting to measure the IQs of a sample composed exclusively of people who traced their ancestry to India but who had been resident in the UK for the entirety of their lives (or even whose ancestors had been resident in the UK for several generations), since all of the other studies cited by Lynn of the IQs of Indian children in the UK presumably include both recent arrivals and long-term residents grouped together.
Interestingly, the high achievement of immigrants, and their descendants, from India is not matched by those from neighbouring countries such as Bangladesh or Pakistan. Indeed, the same data suggesting that Indians are the highest earning ethnicity in Britain also show that British-Pakistanis and Bangladeshis are among the lowest earners in the UK.
The primary divide between these three countries is, of course, not racial but rather religious. This suggests a religion as a causal factor in the difference.
Thus, one study found that Muslim countries tend to have lower average IQs than do non-Muslim countries (Templer 2010; see also Dutton 2020).
Perhaps, then, cultural practices in Muslim countries are responsible for reducing IQs.
Another cultural practice that could affect intelligence in Muslim countries is the practice of even pregnant women fasting during daylight hours during Ramadan (cf. Aziz et al 2004).
However, Lynn’s own data show little difference between IQs in India and those in Pakistan and Bangladesh, nor indeed between IQs in India and those in Muslim countries in the Middle East or North Africa. Nor, according to Lynn’s data, do people of Indian ancestry resident in the UK score noticeably higher in IQ than do people who trace their ancestry to Bagladeshi, Pakistani or Middle Eastern countries.
An alternative suggestion is that Middle-Eastern and North African IQs have been depressed as a result of interbreeding with sub-Saharan Africans, perhaps as a result of the Islamic slave trade.
This would be consistent with the finding that Arab populations from the Middle East show some evidence of sub-Saharan African ancestry in their mitochondrial DNA, which is passed down the female line, but not in their Y-chromosome ancestry, passed down the male line (Richards et al 2003).
In contrast, in the United States, the use of female slaves for sexual purposes, although it certainly occurred, was, at least in theory, very much frowned upon.
In addition, in North America, due to the one-drop rule, all mixed-race descendants of slaves with any detectable degree of black African ancestry were classed as black. Therefore, at least in theory, the white bloodline would have remained ‘pure’, though some mixed-race individuals may have been able to ‘pass’.
Therefore, sub-Saharan African genes may have entered the Middle Eastern, and North African, gene-pools in a way they were not able to do so among whites in North America.
This might explain why genotypic intelligence among North African and Middle Eastern populations may have declined in the period since the great civilizations of Mesopotamia and ancient Egypt and even since the Golden Age of Islam, when the intellectual achievements of Middle Eastern and North African peoples seemed so much more impressive.
Besides Indians, another economically and intellectually overachieving model minority who derive, at least in part, from the race whom Lynn classes as “South Asians and North Africans” are the Jews.
However, in ‘Race Differences in Intelligence’, Jews do not even warrant a chapter of their own. Instead, they are discussed only at the end of the chapter on “South Asians and North Africans”, although Ashkenazi Jews also have substantial European ancestry.
The decision not to devote an entire chapter to the Jewish people is surely correct, because, although even widely disparate groups (e.g. Ashkenazim, Sephardic and Mizrahim, even the Lemba) do indeed share genetic affinities, Jews are not racially distinct (i.e. reliably physically distinguishable on phenotypic criteria) from other peoples.
However, the decision to include them in the chapter on “South Asians and North Africans” is potentially controversial, since, as Lynn readily acknowledges, the Ashkenazim in particular, who today constitute the majority of world Jewry, have substantial European as well as Middle Eastern ancestry.
Lynn claims British and US Jews have average IQs of around 108 (p68). His data for Israel are not broken down by ethnicity, but give an average IQ for Israel as a whole of 95, which Lynn, rather conjecturally, infers scores of 103 for Ashkenazi Jews, 91 for Mizrahi Jews and 86 for Palestinian-Arabs (p94).
Lynn’s explanations for Ashkenazi intelligence, however, are wholly unpersuasive.
First, he observes that, despite Biblical and Talmudic admonitions against miscegenation with Gentiles, Jews inevitably interbred to some extent with the host populations alongside whom they lived. From this, Lynn infers that:
“Ashkenazim Jews in Europe will have absorbed a significant proportion of the genes for higher intelligence possessed by… Europeans” (p95).
It is indeed true that, if, as Lynn claims, Europeans are indeed a more intelligent race than are populations from the Middle East, then interbreeding with Europeans may indeed explain how Ashkenazim came to score higher in IQ than do other populations tracing their ancestry to the Middle East.
However, interbreeding with Europeans can hardly explain how Ashkenazi Jews came to outscore, and outperform academically and economically, even the very Europeans with whom they are said to have interbred!
This explanation therefore fails to explain why Ashkenazim have higher IQs than do Europeans.
Lynn’s second explanation for high Ashkenazi Jewish IQs is equally unpersuasive. He suggests that:
“The second factor that has probably operated to increase the intelligence of Ashkenazim Jews in Europe and the United States as compared with Oriental Jews is that the Ashkenazim Jews have been more subject to persecution… Oriental Jews experienced some persecution sufficient to raise their IQ of 91, as compared with 84 among other South Asians and North Africans, but not so much as that experienced by Ashkenazim Jews in Europe.” (p95).
On purelytheoretical grounds, the idea that persecution selects for intelligence may seem reasonably plausible, if hardly compelling.
However, there is no evidence that persecution does indeed reduce a population’s level of intelligence. On the contrary, other groups who have been subject to persecution throughout much of their histories – e.g. theRoma (i.e. Gypsies) and African-Americans – are generally found to have relatively low IQs.
East and South-East Asians
Excepting Jews, the highest average IQs are found among East Asians, who have, according to Lynn’s data, an average IQ of 105, somewhat higher than that of Europeans (p121-48).
However, it is important to emphasize that this relatively high figure applies only to East Asians – i.e. Chinese, Japanese Koreans, Taiwanese etc.
It does not apply to the related populations of Southeast Asia (i.e. Thais, Filipinos, Vietnamese, Malaysians, Cambodians, Indonesians etc.), who actually score much lower in IQ, with average scores of only around 87 in their indigenous homelands, but rising to 93 among those resident in the US.
Thus, Lynn distinguishes the East Asians from Southeast Asians as a separate race, on the grounds that the latter, despite “some genetic affinity with East Asians” form a distinct genetic cluster in data gathered and analyzed by Cavalli-Sforza et al, and also have distinct morphological features, with “the flattened nose and epicanthic eye-fold… [being] less prominent” than among East Asians (p97).
This is an important point, since many previous writers on the topic have implied that the higher average IQs of East Asians applied to all ‘Asians’ or ‘Mongoloids’, which would presumably include South-East Asians.
Yet, in Lynn’s opinion, it is just as misleading to group all these groups together as ‘Mongoloid’ or ‘Asian’ as it was to group “Europeans” and “South Asians and North Africans” together as ‘Caucasian’ or ‘Caucasoid’.
However, that low scores throughout South-East Asia are entirely genetic in origin is unclear. Thus, Vietnamese resident in the West have sometimes, but not always, scored considerably higher, and Jason Malloy suggests that Lynn exaggerates the overrepresentation of ethnic Chinese among Vietnamese immigrants to the West so as attribute such results to East Asians rather than South-East Asians (Malloy 2014).
Moreover, in relation to Lynn’s ‘Cold Winters Theory’ (discussed below), whereby it is claimed that populations were exposed to colder temperatures during their evolution evolved higher levels of intelligence in order to cope with the adaptive challenges that surviving cold temperatures posed, it is notable that climate varies greatly across China, reflecting the geographic size of the country, with Southern China having a subtropical climate with mild winters.
However, perhaps East Asians, like the Han Chinese, are to be regarded as only relatively recent arrivals in what is now Southern China. This would be consistent with claim of some physical anthropologists that the some aspects of the morphology of East Asians reflects adaptation to the extreme cold of Siberia and the Steppe, and also with the historical expansion of the Han Chinese.
More problematic for ‘Cold Winters Theory’ is the fact that, although Lynn classifies them as East Asian (p121), the higher average IQ scores of East Asians (as compared to whites), does not even extend to the people after whom the Mongoloid race was named – namely the Mongols themselves.
According to Lynn, Mongolians score only around the same as whites, with an average IQ of only 101 (Lynn 2007).
This report is based on just two studies. Moreover, it had not been published at the time the first edition of ‘Race Differences in Intelligence’ came off the presses.
However, Lynn infers a lower IQ for Mongolians from their lower level of cultural, technological and economic development (p240).
Lynn’s explanation for this anomaly is that the low population-size of the Mongols, and their isolation from other populations, meant that the necessary mutations for higher IQ never arose (p240).
This is the same explanation that Lynn provides for the related anomaly of why Eskimos (“Arctic Peoples”), to whom Mongolians share some genetic affinity, also score low in IQ, an explanation that is discussed in the final part of this review.
Another group sometimes subsumed with Asian populations as “Mongoloids” are the indigenous populations of the American continent, namely “Native Americans”.
However, on the basis of both genetic data from Cavalli-Sforza et al and morphological differences (“darker and sometimes reddish skin, hooked or straight nose, and lack of the complete East Asian epicanthic fold”), Lynn classifies them as a separate race and hence accords them a chapter of their own.
His data suggest average IQs of about 86, for both Native Americans resident in Latin America, and also for those resident in North America, despite the substantially higher living standards of the latter (p158; 162-3; p166).
Mestizo populations, however, have somewhat higher scores, with average IQs intermediate between those of the parent populations (p160).
Like the Asian populations with whom they share their ancestry, Native Americans score rather higher on spatio-visual intelligence than on verbal intelligence (p156).
In particular, they also have especially high visual memory (p159-60).
As he did for African-Americans, Lynn also discusses the musical abilities of Native Americans. Interestingly, psychometrical testing shows that their musical ability is rather higher than their general cognitive ability, giving a MQ (Musical Quotient) of approximately 92 (p160).
They also show the same pattern of musical abilities as do African-Americans, with higher scores for rhythmical ability than for other forms of musical ability (p160).
However, whereas blacks, as we have seen, only score as high as Europeans for rhythmical ability, but no higher, Native Americans, because of higher IQs (and MQs) overall, actually outscore both Europeans and African-Americans when it comes to rhythmical ability.
These results are curious. Unlike African-Americans, Native Americans are not, to my knowledge, known for their contribution to any genres of western music, and neither are their indigenous musical traditions especially celebrated.
“Artic Peoples” (i.e. Eskimos)
Distinguished from other Native Americans are the inhabitants of the far north of the American landmass. These, together with other indigenous populations from the area around the Bering straight, namely those from Greenland, the Aleutian Islands, and the far north-east of Siberia, together form the racial group whom Lynn refers to as “Arctic Peoples”, though the more familiar, if less politically correct, term would be ‘Eskimos’.
As well as forming a distinctive genetic cluster per Cavalli-Sforza et al, they are also morphologically distinct, not least in their extreme adaptation to the cold, with, Lynn reports:
As we will see, Lynn is a champion of what is sometimes called ‘Cold Winters Theory’ – namely the theory that the greater environmental challenges, and hence cognitive demands, associated with living in colder climates selected for increased intelligence among those races inhabiting higher latitudes.
Therefore, on the basis of this theory, one might imagine that Eskimos, who surely evolved in one of the most difficult, and certainly in the coldest, environment of any human group, would also have the highest IQs.
This conclusion would also be supported by the observation that, according to the data cited by Lynn himself, Eskimos also have the largest average brain-size of any race (p153).
Interestingly, some early reports did indeed suggest that Eskimos had high levels of cognitive ability as compared to whites. However, Lynn now reports that Eskimos actually have rather lower IQ scores than do whites and East Asians, with results from 15 different studies giving an average IQ of around 90.
Actually, however, viewed in global perspective, this average IQ of 90 for Eskimos is not that low. Indeed, of the ten major races surveyed by Lynn, only Europeans and East Asians score higher.
It is an especially high score for a population who, until recently, lived exclusively as hunter-gatherers. Other foraging groups, or descendants of peoples who, until recently, subsisted as foragers, tend, according to Lynn’s data, to have low IQs (e.g. Australian Aboriginals, San Bushmen, Pygmies).
One obvious explanation for the relatively low IQs of Eskimos as compared to Europeans and East Asians would be their deprived living conditions.
However, Lynn is skeptical of the claim that environmental factors are entirely to blame for the difference in IQ between Eskimos and whites, since he observes:
“The IQ of the Arctic Peoples has not shown any increase relative to that of Europeans since the early 1930s, although their environment has improved in so far as in the second half of the twentieth century they received improved welfare payments and education. If the intelligence of the Arctic Peoples had been impaired by adverse environmental conditions in the 1930s it should have increased by the early 1980s” (p153-4).
He also notes that all the children tested in the studies he cites were enrolled in schools (since this was where the testing took place), and hence were presumably reasonably familiar with the procedure of test-taking (p154).
These are, strictly speaking, somewhat different abilities, although they may not be entirely separate either, and may also be difficult to distinguish between in tests.
If Aboriginals score high on spatial memory, they may then also score high on visual memory, and vice versa for Eskimos and Native Americans. However, since Lynn does not provide comparative data on visual memory among Aboriginals, or on spatial memory among Eskimos or Native Americans, this is not certain.
Interestingly, one thing all these three groups share in common is a recent history of subsisting, at least in part, as hunter-gatherers.
One is tempted, then, to attribute this ability to the demands of a hunter-gatherer lifestyle, perhaps reflecting the need to remember the location of plant foods which appear only seasonally, or to find one’s way home after a long hunting expedition.
It would therefore be interesting to test the visual and spatial memories of other groups who either continue to subsist as hunter-gatherers or only recently transitioned to agriculture or urban life, such as Pygmies and San Bushmen. However, since tests of spatial and visual memory are not included in most IQ tests, the data is probably not yet available.
For his part, Lynn attributes Eskimo visual memory to the need to “find their way home after going out on long hunting expeditions” (p152-3).
“The landscape of the frozen tundra [of the Eskimos] provides few distinctive cues, so hunters would need to note and remember such few features as do exist” (p153).
Proximate Causes: Heredity or Environment?
Chapter fourteen discusses the proximate causes of race differences in intelligence and the extent to which the differences observed can be attributed to either heredity or environmental factor, and, if partly the latter, which environmental factors are most important.
Lynn declares at the beginning of the chapter that the objective of his book is “to broaden the debate” from an exclusive focus on the black-white test score gap in the US, to instead looking at IQ differences among all ten racial groups across the world for whom data on IQ or intelligence is presented in Lynn’s book (p182).
Actually, however, in this chapter alone, Lynn does indeed focus primarily on black-white differences, if only because it is in relation to this difference that most research has been conducted, and hence to this difference that most available evidence relates.
Downplaying the effect of schooling, Lynn identifies malnutrition as the major environmental influence on IQ (p182-7).
However, he rejects malnutrition as an explanation for the low scores of American blacks, noting there is no evidence of short stature in black Americans and nor have surveys have found a greater prevalence of malnutrition (p185).
As to global differences, he concludes that:
“The effect of malnourishment on Africans in sub-Saharan Africa and the Caribbean probably explains about half of the low IQs, leaving the remaining half to genetic factors” (p185).
However, it is unclear what is meant by “half of the low scores” as he has identified no comparison group.
He also argues that the study of racially mixed individuals further suggests a genetic component to observed IQ differences. Thus, he claims:
“There is a statistically significant association between light skin and intelligence” (p190).
As evidence he cites his own study (Lynn 2002) to claim:
“When the amount of European ancestry in American blacks is assessed by skin color, dark-skinned blacks have an IQ of 85 and light-skinned blacks have an IQ of 92” (p190).
However, he fails to explain how he managed to divide American blacks into two discrete groups by reference to a trait that obviously varies continuously.
More importantly, he neglects to mention altogether two other studies that also investigated the relationship between IQ and degree of racial admixture among African-Americans, but used blood-groups rather than skin tone to assess ancestry (Loehlin et al 1973; Scarr et al 1977).
This is surely a more reliable measure of ancestry than is skin tone, since the latter is affected by environmental factors (e.g. exposure to the sun darkens the skin), and could conceivably have an indirect psychological effect.
Meanwhile, Lynn mentions the Eyferth study (1961) of the IQs of German children fathered by black and white US servicemen in the period after World War II, only to report, “the IQ of African-Europeans [i.e. those fathered by the black US servicemen] was 94 in relation to 100 for European women” (p63).
However, he fails to mention that the IQ of those German children fathered by black US servicemen (i.e. those of mixed race) was actually almost identical to that of those fathered by white US servicemen (who, with German mothers, were wholly white). This finding is, of course, evidence against the hereditarian hypothesis with respect to race differences.
Yet Lynn can hardly claim to be unaware of this finding, or its implications with respect to race differences, since this is actually among the studies most frequently cited by opponents of the hereditarian hypothesis with respect to the black-white test score gap for precisely this reason.
Lynn’s presentation of the evidence regarding the relative contributions of heredity and environment to race differences in IQ is therefore highly selective and biased.
“An Evolutionary Analysis”
Only in the last three chapters does Lynn provide the belated “Evolutionary Analysis” promised in his subtitle.
However, in addition, Lynn also traces evolution of intelligence over evolutionary history, both in humans of different races (Chapter 17) and among our non-humans and our pre-human ancestors (Chapter 15).
In discussing the former of these two questions (namely, why race differences in intelligence evolved: Chapter 16), Lynn identifies climate as the ultimate environmental factor responsible for the evolution of race differences in intelligence.
Thus, he claims that, as humans spread out beyond Africa towards regions further from the equator and hence generally with colder temperatures, especially during winters, the colder climates that these pioneers encountered posed greater challenges for the humans who encountered them in terms of feeding themselves and obtaining shelter etc., and that different human races evolved different levels of intelligence in response to the adaptive challenges posed by such difficulties.
Hunting vs. Gathering
The greater problems supposedly posed by colder climates included not just difficulties of keeping warm (i.e. the need for clothing, fires, insulated homes), but also the difficulties of keeping fed.
Thus, Lynn emphasizes the dietary differences between foragers inhabiting different regions of the world:
“Among contemporary hunter-gatherers the proportions of foods obtained by hunting and gathering varies by hunting and by gathering varies according to latitude. Peoples in tropical and subtropical latitudes are largely gatherers, while peoples in temperate environments rely more on hunting, and peoples in arctic and sub-arctic environments rely almost exclusively on hunting and fishing and have to do so because plant foods are unavailable except for berries and nuts in the summer and autumn” (p227).
I must confess that I was previously unaware of this dietary difference. However, in my defence, this is perhaps because many anthropologists seem all too ready to overgeneralize from the lifestyles of the most intensively studied tropical groups (e.g. the San of Southern Africa) to imply that what is true of these groups is true of all foragers, and was moreover necessarily also true of all our hunter-gatherer ancestors before they transitioned to agriculture.
Thus, for example, feminist anthropologists seemingly never tire of claiming that it is female gatherers, not male hunters, who provide most of the caloric demands of foraging peoples.
Actually, however, this is true only for groups inhabiting tropical climes, where plant foods are easily obtainable all year round, not of hunter-gatherers in general (Ember 1978).
It is certainly not true, for example, of Eskimos, among whom females are almost entirely reliant on male hunters to provision them for most of the year, since plant foods are hardly available at all except for during a few summer months.
Similarly, radical-leftist anthropologist Marshall Sahlins famously characterized hunter-gatherer peoples as “The Original Affluent Society”, because, according to his data, they do not want for food and actually have more available leisure-time than do most agriculturalists, and even most modern westerners.
Unfortunately, however, he relied primarily on data from tropical peoples such as the !Kung San to arrive at his estimates, and these findings do not necessarily generalize to other groups such as the Inuit or other Eskimos.
The idea that it was our ancestor’s transition to a primarily carnivorous diet that led to increases in hominid brain-size and intelligence was once a popular theory in paleoanthropology.
However, it has now fallen into disfavour, if only because it put accorded male hunters the starring role in hominid evolution, with female gatherers relegated to a supporting role, and hence offended the sensibilities of feminists, who have become increasingly influential in academia, even in science.
Nevertheless, it is seems to be true that, across taxa, carnivores tend to have larger brains than herbivores.
Of course, non-human carnivores did not evolve the exceptional intelligence of humans.
However, Desmond Morris in The Naked Ape (reviewed here) argued that, because our hominid ancestors only adopted a primarily carnivorous diet relatively late in their evolution, they were unable to compete with such specialized hunters as lions and tigers in terms of their fangs and claws. They therefore had to adopt a different approach, using intelligence instead or claws and fangs, hence inventing handheld weapons and cooperative group hunting.
Thus, in the traditional version, it is the intelligence of early hominids, the descendants all populations of contemporary humans, that increased as a result of the increasing cognitive demands that hunting placed upon us.
However, Lynn argues that it is only certain races that were subject to such selection, as their dependence on hunting increased as they populated colder regions of the globe.
Indeed, Lynn’s arguments actually cast some doubt on the traditional version of the ‘hunting ape theory’.
After all, anatomically modern humans are thought to have first evolved in Africa. Yet if African foragers actually subsisted primarily on a diet of wild plant foods, and only occasionally hunted or scavenged meat to supplement this primarily herbivorous diet, then the supposed cognitive demands of hunting can hardly be invoked to explain the massive increase in hominid brain-size that occurred during the period before our ancestors left Africa to colonize the remainder of the world.
Indeed, Lynn is seemingly clear that he rejects the ‘Hunting Ape Hypothesis’, writing that the increases in hominid brain-size after our ancestors “entered a new niche of the open savannah in which survival was more cognitively demanding” occurred, not because of the cognitive demands of hunting, but rather that:
“The cognitive demands of the new niche would have consisted principally of finding a variety of different kinds of foods and protecting themselves from predators” (p202)
‘Cold Winters Theory’
It may indeed be true that surviving in the extreme cold is more difficult than surviving the sometimes extreme heat of tropical climate. Indeed, this is one reason why the the supposed threat to humanity posed by so-called ‘global warming’ is likely overplayed.
However, there are several problems with so-called ‘Cold Winters Theory’ as an explanation for the race differences in IQ reported by Lynn.
For one thing, other species have adapted themselves to colder climates without evolving a level of intelligence as high as human population, let alone of Europeans and East Asians.
Indeed, I am not aware of any studies even suggesting a relationship between brain-size or intelligence and the temperature or latitude of their species-ranges among non-human species. However, one might expect to find an association between temperature and brain-size, if only because of Bergmann’s rule.
Similarly, Neanderthals were ultimately displaced and driven to extinction throughout Eurasia by anatomically-modern humans, who, at least according to the conventional account, outcompeted Neanderthals due to their superior intelligence and tool-making ability.
At any rate, even if the conditions were indeed less demanding in tropical Africa than in temperate or polar latitudes, then, according to basic Darwinian (and Malthusian) theory, in the absence of some other factor limiting population growth (e.g. warfare, predation, homicide, disease), this would presumably mean that humans would respond to greater resource abundance in the tropics by reproducing until they reached the greater carrying capacity of that environment.
By the time the carrying capacity of the environment was reached, however, the environment would no longer be so resource-abundant given the greater number of humans competing for its resources.
This leads me to believe that the key factors selecting for increases in the intelligence of hominids were not ecological but rather social – i.e. not access to food and shelter etc., but rather competition with other humans.
Also, I remain unconvinced that the environments inhabited by the two races that have, according to Lynn, the lowest average IQs, namely, San Bushmen and Australian Aborigines, are cognitively undemanding.
Meanwhile, the Eskimos occupy what is certainly the coldest, and also undoubtedly one of the most demanding, environments anywhere in the world, and also have, according to Lynn’s own data, the largest brains.
However, according to Lynn’s data, their average IQ is only about 90, high for a foraging group, but well below that of Europeans and East Asians.
For his part, Lynn attempts to explain away this anomaly by arguing that Arctic Populations were precluded from evolving higher IQs by small and dispersed populations, reflecting of the harshness of the environment. This meant the necessary mutations either never arose or never spread through the population (p153; p239-40; p221).
On the other hand, he explains their large brains as reflecting visual memory rather than general intelligence, as well as a lack of mutations for neural efficiency (p153; p240).
However, these seem like post-hoc rationalizations.
After all, if conditions were harsher in Eurasia than in Africa, then this would presumably also have resulted in smaller and more dispersed populations in Eurasia than in Africa. However, this evidently did not prevent mutations for higher IQ spreading among Eurasians.
Why then, when the environment becomes even harsher, and the population even more dispersed, would this pattern suddenly reverse itself?
Likewise, if whole-brain-size is related to general intelligence, it is inconsistent to invoke specific abilities to explain Inuit brains.
Thus, according to Lynn, Australian Aborigines have high spatial memory, which is closely related to visual memory. However, also according to Lynn, only their right visual cortex is enlarged (p108-9) and they have small overall brain-size (p108-9; p210; p212).
 Curiously, Lynn reports, this black advantage for movement-time does not appear in the simplest form of elementary task (simple reaction time), where the subject simply has to press a button on the lighting of a light, rather than hitting a specific button, rather than alternative buttons, on the lighting of a particular light rather than other lights (p58). These latter forms of elementary cognitive test presumably involve some greater degree of cognitive processing.
 First, there are the practical difficulties. Obviously, non-human animals cannot use written tests, or an interview format. Designing a maze for laboratory mice may be relatively straightforward, but building a comparable maze for elephants is rather more challenging. Second, and more important, different species likely have evolved different specialized abilities for dealing with specific adaptive problems. For example, migratory birds may have evolved specific spatio-visual abilities for navigation. However, this is not necessarily reflective of high general intelligence, and to assess their intelligence solely on the basis of their migratory ability, or even their general spatio-visual ability, would likely overestimate their general level of cognitive ability. In other words, it reflects a modular, domain-specific adaptation. Admittedly, the same is true to some extent for human races. Thus, some races score relatively higher on certain types of intellectual ability. For example, East Asians tend to score higher on spatio-visual ability than on verbal ability; Ashkenazi Jews show the opposite pattern, scoring higher in verbal intelligence than in spatio-visual ability; while American blacks score relatively higher in tests involving rote memory than in those requiring abstract reasoning ability. Similarly, as discussed by Lynn, some races seem to have certain quite specific abilities not commensurate to their general intelligence (e.g. Aborigine visual memory). However, in general, both between and within races, most variation in human intelligence loads onto the ‘g-factor’ of general intelligence.
 American anthropologist Carleton Coon is credited as the first to first to propose that population differences in skull size reflect a thermoregulatory adaptation to climatic differences (Coon 1955). An alternative theory, less supported, is that it was differing levels of ambient light that resulted in differences in brain-size as between different populations tracing their ancestry to different parts of the globe (Pearce & Dunbar 2011). On this view, the larger brains of populations who trace their descent to areas of greater latitude presumably reflect only the demands of the visual system, rather than any differences in general intelligence. Yet another theory, less politically-correct than these, is so-called ‘Cold Winters Theory’, which posits that colder climates placed a greater premium on intelligence, which caused populations inhabiting colder regions of the globe to evolve larger brains and higher levels of intelligence. This is, of course, the theory championed by Lynn himself, and I discuss the problems with this theory the final part of this review.
 Curiously however, although, as reported by Lynn, the cold-adapted Eskimos indeed have the largest brains of any human poulation, the same does not seem to be true of another arctic population, namely the reindeer-herding Sámi (or Lapps) of Scandinavia and the Kola Penninsula. On the contrary, anthropologist Carleton Coon reports that the Sámi actually “have very small heads” (The Races of Europe: p266). This would seem to be contrary to Bermann’s Rule. However, this may be accounted for by the diminutive stature of Sámi. Thus, head-size (and brain-size) also correlates with overall body-size, and Coon also reports that, although small in absolute size, Sámi heads are actually “large in proportion to body size” (The Races of Europe: p303).
 Lynn has recently published research regarding differences in IQ across different regions of Italy (Lynn 2010).
 Actually, Lynn acknowledges causation in both directions, possibly creating a feedback loop. He also acknowledges other factors in contributing to differences in economic development and prosperity, including the effects of the economic system adopted. For example, countries that adopted communism tend to be poorer than comparable countries that have capitalist economies (e.g. Eastern Europe is poorer than Western Europe, and North Korea poorer than South Korea).
 Incidentally, Lynn cites two studies of Polish IQ, whose results are even more divergent than those of Portugal or Ireland, giving average IQs of 106 and 91 respectively. One of these scores is substantially below the European average, while the other the substantially above.
 Essayist Ron Unz has argued that IQs in Ireland have risen in concert with living standards in Ireland (Unz 2012a; Unz 2012b). However, judging from dates when the studies cited by Lynn in ‘Race Differences in Intelligence’ were published, there is no obvious increase over time. True the earliest study, an MA thesis, published in 1973 gives the lowest figure, with an average IQ of just 87 (Gill and Byrt 1973). This rises to 97 in a study published in 1981 that provided little details on its methodology (Buj 1981). However, it declines again for in the latest study cited by Lynn on Irish IQs, which was published in 1993 but gives average IQs of just 93 and 91 for two separate samples (Carr 1993). In the more recent 2015 edition, Lynn cites a few extra studies, eleven in total. Again, however, there is no obvious increase over time, the latest study cited by Lynn, which was published in 2012, giving an average IQ of just 92 (2015 edition).
 While this claim is made in reference to immigrants to America and the West, it is perhaps worth noting that East Asians in South-East Asia, namely the Overseas Chinese, largely dominate the economies of South-East Asia, and are therefore on average much wealthier than the average Chinese person still residing in China (see World on Fire by Amy Chua). Given the association of intelligence with wealth, this would suggest that Chinese immigrants to South-East Asia are not substantially less intelligent than those who remained in China. Did the more intelligent Chinese migrate to South-East Asia, while the less intelligent migrated to America? If so, why would this be?
 Other Catholic countries, namely those in Southern Europe, such as Italy and Spain, may indeed have slightly lower IQs, at least in the far south of these countries. However, as we have seen, Lynn explains this in terms of racial admixture from Middle-Eastern and North African populations. Therefore, there is no need to invoke priestly celibacy in order to explain it. The crucial test case, then, is Catholic countries other than Ireland from Northern Europe, such as Austria and France.
 However, it is not at all clear that the same is true for black African minorities resident in other western polities, whose IQs are also, according to Lynn’s data, also considerably above those for indigenous Africans. Here, I suspect black populations are more diverse. For example, in Britain, Afro-Caribbean people, who emigrated to Britain by way of the West Indies, are probably mostlymixed-race, like African-Americans, since both descend from white-owned slave populations. However, Britain also plays host to many immigrants direct from Africa, most of whom are, I suspect, of relatively unmixed sub-Saharan African descent. Yet African immigrants to the UK outperform Afro-Caribbeans in UK schools (Chisala 2015a).
 Blogger John ‘Chuck’ Fuerst suggests, the higher scores for Somali immigrants might reflect the fact that the peoples of the Horn of Africa actually, as we have seen, have substantial Caucasoid ancestry, and genetic affinities with North African and Middle Eastern populations (Fuerst 2015). However, the problem with attributing the relatively high scores of Somali refugees and immigrants to Caucasoid-admixture is that, as we have seen, according to the data collected by Lynn, IQs are no higher in the Horn of Africa than elsewhere in sub-Saharan Africa.
 If anything, “Bushmen” should presumably be grouped, not with Pygmies, with rather the distinct but related Khoikhoi pastoralists. However, the latter are now all but extinct as an independent people and are not mentioned by Lynn.
 For example, Lynn also acknowledges that those whom he terms “South Asians and North Africans” are “closely related to the Europeans” (p79). However, they nevertheless merit a chapter of their own. Likewise, he acknowledges that “South-East Asians” share “some genetic affinity with East Asians with whom they are to some degree interbred” (p97). Nevertheless, he justifies considering these two ostensible races in separate chapters, partly on the basis that “the flattened nose and epicanthic eye-fold are less prominent” among the former (p97). Yet the morphological differences between Pygmies and Khoisan are even greater, but they are lumped together in the same chapter.
 There is indeed, as Lynn notes, a correlation between a group’s IQ and their lifestyle (i.e. whether they are foragers or agriculturalists). However, the direction of causation is unclear. Does high intelligence allow a group to transition to agriculture, or does an agriculturalist lifestyle somehow increase a group’s average IQ? And, if the latter, is this a genetic or a purely environmental effect?
 Indeed, the very word ‘slave’ is thought to derive from the ethnonym ‘Slav’, because of the frequency with which Slavic peoples were enslaved during the Middle Ages.
 Indeed, Lynn could hardly have arrived at an actual figure for the average Pygmy IQ, since, as we have seen, he reports the results of only a single actual study of Pygmy intelligence, the author of which did not present his results in a quantitative format.
 Thus, he suggests that the lower performance of the Aboriginals tested by Drinkwater (1975), as compared to those tested by Kearins (1981), may reflect the fact that the latter were the descendants of coastal populations of Aborigines, for whom the need to navigate in deserts without landmarks would have been less important.
 The fact that the earliest civilization emerged among Middle Eastern, North African and South Asian populations is attributed by Lynn to the sort of environmental factors that, elsewhere in his book, he largely discounts. Thus, Lynn writes:
“[Europeans] were not able to develop early civilizations like those built by the South Asians and North Africans because Europe was still cold, was covered with forest, and had heavy soils that were difficult to plough unlike the light soils on which the early civilizations were built, and there were no river flood plains to provide annual highly fertile alluvial deposits from which agricultural surpluses could be obtained to support an urban civilization and an intellectual class” (p237).
 An interesting question is whether there exist differences in IQ as between different caste groups within the Indian subcontinent, since, at least in theory, these represented endogamous breeding populations between whom strict separation was maintained. Thus, it would be interesting to know the average IQ of Brahmins or of the high-achieving Parsi people (though the latter are not strictly a caste, since they are not Hindu).
 However, all of these comparisons, in both Britain and America, omit to include Jewish people as a separate ethnicity, instead grouping them with other whites. Jews earn more, on average, than any other religion in Britain and America, including Hindus.
 I assume that this is the study that Lynn is citing, since this is the only matching study included in his references. However, curiously, Lynn refers to this study here as “Mackintosh et al 1985” (p83-4), despite their being only two authors listed in his references, such that “Mackintosh & Mascie-Taylor 1985” would be the more usual citation. Indeed, Lynn uses this latter form of citation (i.e. “Mackintosh & Mascie-Taylor 1985”) elsewhere when citing what seems to be the same paper in his earlier chapter on Africans (p47; p49).
 An alternative possibility is that it was the spread of Arab genes, as a result of the Arab conquests, and resulting spread of Islam, that depressed IQs in the Middle-East and North Africa, since Arabs were, prior to the rise of Islam, a relatively backward group of desert nomads, whose intellectual achievements were minimal compared to those of many of the groups whom they conquered (e.g. Persians, Mesopotamians, Assyrians, and Egyptians). Indeed, even the achievements of Muslim civilization during the Islamic Golden Age were disproportionately those of the Persians, not the Arabs.
 One might, incidentally, question Lynn’s assumption that Oriental Jews were less subject to persecution than were the Ashkenazim in Europe. This is, of course, the politically correct view, which sees Islamic civilization as, prior to recent times, more tolerant than Christendom. On this view, anti-Jewish sentiment only emerged in the Middle East as a consequence of Zionism and the establishment of the Jewish state in what was formerly Palestine. However, for alternative views, see The Myth of the Andalusian Paradise. See also Robert Spencer’s The Truth About Muhammad (which I have reviewed here), in which he argues that Islam is inherently antisemitic (i.e. anti-Jewish). Interestingly, Kevin Macdonald, in A People That Shall Dwell Alone (which I have reviewed here and here) makes almost the opposite argument to that of Lynn. Thus, he argues that it was precisely because Jews were so discriminated against in the Muslim world that their culture, and ultimately their IQs, were to decline, as they were, according to Macdonald, largely excluded from high-status and cognitively-demanding occupations, which were reserved for Muslims (p301-4). Thus, Macdonald concludes:
“The pattern of lower verbal intelligence, relatively high fertility, and low-investment parenting among Jews in the Muslim world is linked ultimately to anti-Semitism” (A People That Shall Dwell Alone (reviewed here): p304).
 For example, one might speculate that only the relatively smarter Jews were able to anticipate looming pogroms and hence escape. Alternatively, since wealth is correlated with intelligence, perhaps only the relatively richer, and hence generally smarter, Jews could afford the costs of migration, including bribes to officials, in order to escape pogroms. These are, however, obviously speculative, post-hoc ‘just-so stories’ (in the negative Gouldian sense), and I put little stock in them.
 This pattern among East Asians of lower scores on the verbal component of IQ tests was initially attributed to a lack of fluency in the language of the test, since the first East Asians to be tested were among diaspora populations resident in the West. However, the same pattern has now been found even among East Asians tested in their first language, in both the West and East Asia.
 For example, Sarich and Miele, in Race: The Reality of Human Differences (which I have reviewed here and here) write that “Asians have a slightly higher IQ than do whites” (Race: The Reality of Human Differences: p196). However, in actuality, this applies only to East Asians, not to South-East Asians (nor to South Asians and West Asians, who are “Asian” in at least the geographical, and the British-English, sense.) Similarly, in his own oversimplified tripartite racial taxonomy in Race, Evolution and Behavior(which I have reviewed here), Philippe Rushton seems to imply that the traits he attributes to ‘Mongoloids’, including high IQs and large brain-size, apply to all members of this race, including South-East Asians and even Native Americans.
 Ethnic Chinese were overrepresented among Vietnamese boat people, though less so among later waves of immigrants. However, perhaps a greater problem is that they were disproportionately middle-class and drawn from the business elite, and hence unrepresentative of the Vietnamese as a whole, and likely of disproportionately high cognitive ability.
 In his paper on Mongolian IQs, Lynn also suggests that Mongolians have lower IQs than other East Asians because they are genetically intermediate between East Asians and Eskimos (“Arctic Peoples”), who themselves have lower IQs (Lynn 2007). However, this merely begs the question as to why Eskimos themselves have lower IQs than East Asians, another anomaly with respect to ‘Cold Winters Theory’, which is discussed in the final part of this review.
 With regard to the population of Colombia, Lynn writes:
“The population of Colombia is 75 percent Native American and Mestizo, 20 percent European, and 5 percent African. It is reasonable to assume that the higher IQ of the Europeans and the lower IQ of the Africans will approximately balance out and that the IQ of 84 represents the intelligence of the Native Americans” (p58).
However, this assumption that the African and European genetic contributions will balance out seems dubious since, by Lynn’s own reckoning, the European contribution to the Colombian gene-pool is three times greater than that of Africans.
 The currently-preferred term ‘Inuit’ is not sufficiently inclusive, because it applies only to those Eskimos indigenous to the North American continent, not the related but culturally distinct populations inhabiting Siberia or the Aleutian Islands. I continue to use the term Eskimos, because it is more accurate, not obviously pejorative, probably more widely understood, and also because I deplore the euphemism treadmill. Elsewhere, I have generally deferred to Lynn’s own usage, for example mostly using ‘Aborigine’, rather than the now preferred ‘Aboriginal’, a particularly preposterous example of the euphemism treadmill since the terms are so similar, comparable to how, today, it is acceptable to say ‘people of colour’, but not ‘coloured people’.
 Certain specific subpopulations also score higher (e.g. Ashkenazim and Māoris, though the latter only barely). However, these are subpopulations within the major ten races that Lynn identifies, not races in and of themselves.
 Actually, by the time Columbus landed in the Americas, many Native Americans had already partly transitioned to agriculture. However, not least because of a lack of domesticated animals that they could use as a meat source, most supplemented this with hunting and sometimes gathering too.
 However, Lynn reports that Japanese also score high on tests of visual memory (p143). However, excepting perhaps the Ainu, the Japanese do not have a recent history of subsisting as foragers. This suggests that foraging is not the only possible cause of high visual memory in a population.
 Presumably the comparison group Lynn has in mind are Europeans, since, as we have seen it is European living standards that he takes as his baseline for the purposes of estimating a group’s ”genotypic IQ” (p69), and, in a sense, all the IQ scores that he reports are measured against a European standard in so far as they are calculated by reference to an arbitrarily assigned average of 100 for European populations.
 Thus, it is at least theoretically possible that a relatively darker-skinned African-American child might be treated differently than a lighter-skinned child, especially one whose race is relatively indeterminate, by others (e.g. teachers) in a way that could conceivably affect their cognitive development and IQ. In addition, a darker skinned African-American child might, as a consequence of their darker complexion, come to identify as an African American to a greater extent than a lighter skinned child, which might affect who they socialize with, which celebrities they identify with and the extent to which they identify with broader black culture, all of which could conceivably have an effect on IQ. I do not contend that these effects are likely or even plausible, but they are at least theoretically possible. Using blood group to assess ancestry, especially if one actually introduces controls for skin tone (since this may be associated with blood-group, since both are presumed to be markers of degree of African ancestry), obviously eliminates this possibility. Today, this can also be done by looking at subjects’ actual DNA, which obviously has the potential to provide a more accurate measure of ancestry than either skin-tone or blood-group (e.g. Lasker et al 2019).
 More recently, a better study has been published regarding the association between European admixture and intelligence among African-Americans, which used genetic data to assess ancestry, and actually sought to control for the possible confounding effect of skin-colour and appearance (Lasker et al 2019). Unlike the blood-group studies, this largely supports the hereditarian hypothesis. However, this was not available at the time Lynn authored his book. Also, it ought to be noted that it was published in a controversial pay-to-publish academic journal, and therefore the quality of peer review to which the paper was subjected may be open to question. No doubt in the future, with the reduced costs of genetic testing, more studies using a similar methodology will be conducted, finally resolving the question of the relative contributions of heredity and environment to the black-white test score gap in America, and perhaps disparities between other ethnic groups too.
 It is a fallacy, however, to assume that what is true for those foraging peoples that have managed to survive as foragers in modern times and hence come to be studied by anthropologists was necessarily also true of all foraging groups before the transition to agriculture. On the contrary, those foraging groups that have survived into modern times, tend to have done so only in the ecologically most marginal and barren environments (e.g. the Kalahari Desert occupied by the San), since these areas are of least use to agriculturalists, and therefore represent the only regions where more technologically and socially advanced agriculturalists have yet to displace them (see Ember 1978). However, this would seem to suggest that African hunter-gatherers, prior to the expansion of Bantu agriculturalists, would have occupied more fertile areas, and therefore might have had even less need to rely on hunting than do contemporary hunter-gatherers such as the San, who are today largely restricted to the Kalahari Desert.
“Hunting in the open grasslands of northern Europe was more difficult than hunting in the woodlands of the tropics and subtropics where there is plenty of cover for hunters to hide in” (Race, Evolution and Behavior: p228).
In contrast, Lynn argues “open grasslands”, albeit on the African Savannah rather than in Northern Europe, actually made things harder, not for predators, but rather for prey – or at least arboreal primate prey. Thus, Lynn writes:
“The other principle problem of the hominids living in open grasslands would have been to protect themselves against lions, cheetahs and leopards. Apes and monkeys escape from the big cats by climbing into trees and swinging or jumping form one tree to another. For the Autralopithecines and the later hominids in open grasslands this was no longer possible” (p203).
 To clarify, this is not to say that either San Bushmen or Australian Aborigines evolved primarily in these desert environments. On the contrary, many of them formerly occupied more fertile areas, before being displaced by more advanced neighbours, Bantu agriculturalists in the case of Khoisan, and European (more specifically British) colonizers, in the case of Aborigines. However, that they are nevertheless capable of surviving in these demanding desert environments suggests either:
(1) They are more intelligent than Lynn concludes; or (2) That surviving in challenging environments does not require the level of intelligence that Lynn’s ‘Cold Winters Theory’ supposes.
 Besides Eskimos, another potential test case for ‘Cold Winters Theory’ are the Sámi (or Lapps) of Northern Scandinavia. Like Eskimos, they have inhabited an extremely cold, northern environment for many generations and are genetically, and morphologically, quite distinct from other populations. Also, again like Eskimos, they maintained a foraging lifestyle until modern times. However, unlike other cold-adapted populations, the Sámi have, according to Carleton Coon, “very small heads” and hence presumably not especially large brains, though he also reports that their head-size is actually large in proportion to body-size. (The Races of Europe: p266; p303). According to Armstrong et al (2014), the only study of Sámi cognitive ability of which I am aware, the average IQ of the Sámi is almost identical to that of neighbouring populations of Finns (about 101).
 Lynn gives the same explanation for the relatively lower recorded IQs of Mongolians, as compared to other East Asians (p240).
