Black Brain, White Brain: Is Intelligence Skin Deep?
`Punchy and perceptive, Evans’ passionate and wide-ranging debunking of hereditarian views of race in areas ranging from archaeology to IQ and sport deserves a wide readership.’
Professor Saul Dubow, University of London
‘Smart, accessible and stimulating, Black Brain White Brain is by far the most important book yet written to systematically debunk society’s lingering attachments to race science and its pet topics of intelligence, genetics and civilization. Black Brain White Brain should be required reading in every undergraduate university course, in every high school and in every home.’
Professor Jonathan Jansen, University of the Free State
Over the last decade the media have given new life to an old idea – one at least as old as colonialism and slavery: that intelligence is defined by race and, more specifically, that white and Asian people are innately smarter than black people.
The prime sources for these successive waves of publicity are psychologists but a handful or renegade scientists, pop science writers and journalists have joined the throng.
Gavin Evans demonstrates why they are wrong – that their ideas are based on an out-of-date understanding of genetics, on a profound ignorance of the African anthropological record and a misplaced faith in the idea that IQ tests measure hardwired general intelligence, and that average IQ scores of different populations can be fruitfully compared.
Black Brain, White Brain shows that there are no hardwired differences in intelligence or character between the races, and that human brainpower has probably not evolved for 100,000 years.
'Gavin Evans studied economic history and law, has a PhD in politics and has worked as a journalist for 25 years. He has read widely on evolutionary biology, palaeontology, biological anthropology, archaeology, neuroscience and evolutionary psychology. He needed all this for his latest book, Black Brain, White Brain. It plunges deep into the world of racist science and demolishes its myths quickly and smartly.'
Rehana Rossouw, Business Day
‘The title of Gavin Evans' new work, Black Brain, White Brain: Is intelligence skin deep? is seemingly problematic. Surely we know the answer to that question? Evidently not. Spend a few moments with this valuable and indeed welcome work and it becomes quite clear there are a lot of supposedly learned folk out there who, frankly, should know better.’
Andrew Donaldson, The Times
‘Gavin Evans, journalist and author of Black Brain, White Brain: Is intelligence skin deep? is more au fait with scientific racism, having grown up and worked in apartheid South Africa where "science" was used to justify white superiority. … Evans lays out the reason he believes science does not support the idea that intelligence is determined by race, with an impressive list of scientific references and interviews to back up his rationale.'
Sarah Wild, Mail & Guardian.
'A new book by Hornsey author, journalist and Birkbeck media studies lecturer Gavin Evans is aiming to debunk the idea that white and Asian people are innately smarter than black people. Black Brain, White Brain: Is intelligence skin deep? took two years to write and is partly inspired by his experiences of growing up in South Africa where he fought against apartheid.'

Gavin Evans has written a pseudo-scientific book Black Brain, White Brain: Is Intelligence Skin Deep?
Gavin Evans has a Ph.D. in politics. However, this book is all about genetics, race, and intelligence. Some people may feel he’s not qualified to write such a book but I disagree. You don’t have to have a diploma in a subject matter in order to have an educated opinion on the matter.
Still, he has the audacity to write, “Even the finest scientific minds are capable of coming up with ridiculous theories when tackling subjects beyond their own calling.” (Loc 154)
For example, James Watson, co-discoverer of DNA’s structure, said that he was “inherently gloomy about the prospect of Africa” because “all our social policies are based on the fact that their intelligence is the same as ours—whereas all the testing says not really.”
Evans thinks the Nobel-Prize-winning Watson shouldn't "tackle subjects beyond his calling," but somehow Evans feels it's acceptable for he himself to do so. That sounds like arrogance or hypocrisy. Or both.
Of course, I'm currently also "tackling subjects beyond my calling" by reviewing this book about genetics and intelligence. But as I said from the beginning, I don't have a problem with Evans (or anyone) debating things outside of their "official" realm of expertise. It's just like I dislike it that sometimes young people aren't allowed to voice opinions "because they have no experience."
My annoyance is simply that Evans doesn't see the hypocrisy of his criticism of Watson and other intelligent people.
Are IQ tests useful?
Evans argues that IQ tests measure “a certain kind of abstract logic. They do not, and cannot, measure ‘general’ intelligence.” (Loc 141)
Perhaps.
But maybe “abstract logic” is the key component of general intelligence that matters. If rich and powerful people are far better at abstract logic than extremely poor people, then IQ tests are relevant and good predictors of a person’s future or potential. If countries or races that excel at abstract logic have a higher standard of living than those groups that have poor abstract logic, then we ought to pay attention that metric.
Yes, correlation does not equal causation, but a correlation is a signal that we ought to study the issue carefully and without bias to determine if there is causation.
Evans is hypocritical. He spends much time arguing that IQ tests are useless but then he uses them to justify his views on intelligence. For example, he points out that “educational levels, social class and exposure to knowledge could have prompted significant differences in adult IQs, which is hardly surprising.” (Loc 2654).
The smart arguments
On the plus side, the book provides good counterarguments against the hereditary arguments. Moreover, there’s this good excerpt:
“Some cultures are superior to others—not . . . through intellectual achievements, but rather because they treat people better. It follows that some are inferior. Cultures where rape is acceptable, where girls are banned from education, where men are permitted to murder daughters who are raped or who bring ‘dishonor’ to their families, where female genital mutilation is practiced, or where people are attacked or oppressed because of their color, tribe, language or religion, are inferior to cultures where these forms of barbarism and idiocy are unacceptable.” (Loc 864).
That's nice, although it’s a pity that he can’t even admit that the intellectual achievements are some cultures are inherently superior to others. China and England have delivered so many intellectual achievements. What has Comoros done? What is so wrong to admit that Hungary has produced more science noble prize winners than all of Africa?
We can debate why Hungary has more Nobel Laureates than Africa but there is no debate that this is a fact and that it's strong evidence that one culture is superior to another when measuring intellectual achievements.
But, of course, Evans would never let himself consider such a possibility.
Are we also going to deny that East Africans have athletic achievements in marathon distances?
Actually, Evans tries (unconvincingly) to deny just that.
Playing the "racism" card
Evans says, “No one denies that environment has something to do with racial differences. But every mainstream academic working in this area would dispute the claim that genes have anything to do with racial differences in IQ.” (Loc 3416)
Really? He dismisses Nicolas Wade, who was the New York Times Science editor. Apparently, he's not part of the “academic mainstream.” Why? Because he wrote a “toxic” book, A Troublesome Inheritance, which I also reviewed.
Nor does Harvard genius Steven Pinker (whom Time magazine named Top 100 most influential people) qualify as “mainstream” in Evans’s book. Pinker just another “racist” because he observed and explained why Jews have high IQ scores.
Ultimately, it is these arguments that spoil Evans’s book. He is unwilling to grant even one centimeter to the hereditary argument.
In Evans's world, everyone who argues that genes play some role (even a small role) in determining a person’s or a group’s intelligence is automatically a “racist.” He constantly labels all his enemies “racists” because it’s such a powerful insult. According to the Kindle's search feature, he uses the word “racist” over 250 times in the book.
Calling people “racist” is all the “evidence” Evans feels is necessary to refute their ideas. It’s really childish to just call your opponents names without focusing exclusively on the evidence and trying to understand their arguments.
I’m not suggesting that Evans doesn’t present evidence. He does. Unfortunately, his mind is so unscientific (he is the poster child for confirmation bias) and his emotional jabs at his enemies are so infantile that his arguments lose credibility.
Is it really that unreasonable to say that genetics plays a role in determining intelligence?
As Evans points out, Nicolas Wade, Steven Pinker, Richard Lynn, and others never argue that DNA determines intelligence or that it is 100% behind your IQ. Instead, they all argue that genes explain 30-70% of intelligence, depending on the author and the study.
Evans could win so much respect if he wasn’t so dogmatic and emotional. If Evans simply was willing to admit that genes play a small role, even a tiny role (like 10%), then his book would be far more credible than it is.
Did intelligence stop evolving 100,000 years ago?
Why does Evans think that intelligence permanently stopped evolving over 100,000 years ago? He says, “Humans were innovating in symbolic ways 50,000 years before they migrated to Europe, which suggests that while cultural and scientific innovation knows few bounds, base human intelligence has not evolved for a very long time.”
So because Africans drew some crude illustrations on caves over 100,000 years ago, human intelligence hasn’t improved in any group anywhere on Earth.
Really?
Meanwhile, skin color, eye color, eye shape, sickle cell anemia, the Duffy antigen, high altitude advantages, and countless of other changes happened in different groups in the last 20,000 years (even 10,000 years), but intelligence was magically sealed in a “do not touch this” DNA box for over 100,000 years.
Evans spends lots of time discussing the Flynn Effect (evidence that IQ rates have been steadily and rapidly increasing in the last 100 years). Now don't you think if IQs have been rising that fast that maybe they might also evolve in 10,000 years?
Evans needs to study epigenetics.
But he's bullheaded. Evans writes, “For as long as a species survives, it will usually not change a great deal. This applies particularly to human intelligence because, unlike skin color or ethnic diseases, it involves thousands of genes.” (Loc 4280)
Really? Then explain dogs.
Yes, obviously man has bred dogs but dogs demonstrate that a species can change a great deal when the environment challenges them in a different way. Humans selected dogs to help mold the various breeds. Any dog specialist will tell you that certain breeds are far more intelligent than others, even though intelligence involves thousands of genes. Dogs prove that a species can change a great deal and the intelligence between sub-species can also change a great deal.
Homo sapiens faced different challenges once they left Africa’s savanna behind. The frozen Arctic poses severe environmental challenges and could alter human intelligence much in the same way that humans have altered dog intelligence.
Ask any dog trainer if Border Collies are smarter than a Chow Chow and he will, without hesitation, agree. If you ask the dog specialist if the intelligence gap is mostly (or at least partly) genetic, he will undoubtedly agree that genes play a huge role.
Genetics is a key reason why a German Shepard is smarter than a Pekingese.
If dogs were as politically correct as humans, they would try to claim that whatever perceived differences in dog IQ can all be explained, exclusively, by environmental factors. And we humans would just shake our heads at their blockheadedness.
Does not knowing which genes influence intelligence mean that such genes don't exist?
Evans writes, “Even the most fervent of genetic determinists have struggled to find genes for intelligence.” (Loc 4661).
As if this proves that such genes don’t exist. We don’t know the precise genes that determine eye color, height, and skin color, so do those genes also not exist?
In the 1950s, scientists knew that DNA existed even though they knew nothing about its exact shape and way of working. Astronomers knew Pluto existed before anyone saw it (they could indirectly verify its existence through gravitational fluctuations). Therefore, just because we don't know exactly which genes influence intelligence doesn't mean that they don't exist.
It’s almost certain that in this century we will discover the genes that determine every human attribute. We already know that everything about us has a physical manifestation. Everything about us, including our love, hate, personalities, preferences, and looks are all determined by chemicals and molecules in our body. We can certainly influence and change these molecules with our behavior, electrical impulses, or drugs.
Evans will have to eat his words when researchers in this century prove which genes determine intelligence for our species. Those who think/hope that those genes will never found or understood severely underestimate the progress of genetic research.
South Africa
Evans, who is from South Africa, writes, “I spent most of my first three decades living in a country where a minority believed the majority was unfit to rule because they lacked the intelligence, character and culture for the job—but mainly the intelligence.”
Now, nearly three decades since that country (South Africa) has been independent. An impartial Martian would probably say that the evidence so far has proven those “racists” right. After a good decade with Mandela, South Africa has gone steadily downhill, overall. Yes, some things have improved and South Africa isn’t as bad as Zimbabwe (another country that whites ruled and went into the toilet after they left). South Africa and Zimbabwe were the richest and most advanced Sub-Saharan countries. If they lose that lead, it hurts the “there are no racial differences in intelligence” argument. Let's hope South Africa turns things around after President Zuma leaves this year.
In a Facebook post, a popular South African asked people to complete this sentence, "South Africa would be so much better if...."
The top comment with over 450 positive reactions was by a black woman who wrote "...If we could distinguish between disagreements and racism."
Evans needs to understand that because, in his white brain, he sees any disagreement with his book as a sure sign that he's talking with a racist.
If Evans were to read my review, he would label me as a “racist troll.” Indeed, he predicts that trolls like me would pounce on his book. He suggests there’s a conspiracy against it. It’s funny because Nicolas Wade argues the same thing in his book. Wade suggests that the media and especially academia is strongly against any research on race.
Evans thinks the opposite. Evans views his we’re-all-created-equal argument as the underdog as if we’re living in the 1800s.
I side with Wade. The politically correct mafia, which Evans seems to be a gang leader, is alive and well. Their tactics are easy and obvious: just scream "racist" loudly and often.
Gavin Evans reveals his true bias at the end of the book
Evans effectively admits that he’s biased and unscientific. He writes, "I was intensely involved in anti-apartheid activities in the 1980s."
He adds, “Racism is an issue I feel strongly about. It upsets me, deeply and personally, and I believe that its faux-scientific expression is its most insidious version.” (Loc 4640).
I rest my case.
Evans is not an open-minded, objective scientist. He is on an emotional mission to discredit anyone who makes an argument that some groups may be smarter than other groups.
He champions the idea that we are all blank slates (an idea that Stephen Pinker brilliantly demolishes in his book The Blank Slate).
Evans concludes his book with this feel-good (but misleading) message: “But despite these huge environmental differences, we can be sure of one thing: within any population group we choose to name we will find the full spread, in roughly equal proportions, of human nature: cruelty and kindness, violence and gentility, madness and sanity, inventiveness and placidity, idiocy and genius.”
If you’re equally emotional about this issue, then you will love Evans’s book.
If, however, you wish to examine the issue calmly and dispassionately, this book is worthless.
The verdict on Black Brain, White Brain: 1 out 10 stars.
Am I a racist?
For those who made it this far and conclude that I’m a racist, then you’re misunderstanding me.
I, like Pinker and Wade, am not suggesting that DNA is the sole or even main determinant of one’s intelligence.
I’m simply saying it’s a factor, just like one’s environment is a factor. Maybe it's just 10% (although most objective studies suggest that it's at least 30%).
And yes, some groups are smarter than others, just like some groups are faster than others, taller than others, and fatter than others. Why groups differ from one another has to do with an interplay of genes and environment. We can debate what how important DNA is versus the environment, but let’s not pretend it’s 100% environment, even if that’s the answer that would make us feel good.
Furthermore, I married a black African from Cameroon (see photo) because she's brilliant. Just because groups have tendencies doesn't mean that all the individuals in that group have those tendencies.
True racists don't allow for exceptions. In their brains, Jews are always smart, blacks are always stupid. Their mind is closed. They'll struggle to admit, for example, that Barack Obama's Kenyan father was smarter than many/most Jews.
Lastly, please study epigenetics. I may have to write a book about epigenetics because it's such an important topic that most people don't know anything about.
The notion that DNA is immutable is a 20th-century idea. In this century, thanks to epigenetics, we are learning that DNA is incredibly flexible and fast changing.
So just because a group (or an individual) has “undesirable” DNA doesn’t doom it for eternity or even a lifetime.
DNA gives us tendencies but it doesn’t determine our fate.
Disclosure: the publisher of Black Brain, White Brain, gave me a free copy of the book to do an honest review. They probably regret doing that!

The verdict on Black Brain, White Brain: 1 out 10 stars.
Am I a racist?
For those who made it this far and conclude that I’m a racist, then you’re misunderstanding me.
I, like Pinker and Wade, am not suggesting that DNA is the sole or even main determinant of one’s intelligence.
I’m simply saying it’s a factor, just like one’s environment is a factor. Maybe it's just 10% (although most objective studies suggest that it's at least 30%).
And yes, some groups are smarter than others, just like some groups are faster than others, taller than others, and fatter than others. Why groups differ from one another has to do with an interplay of genes and environment. We can debate what how important DNA is versus the environment, but let’s not pretend it’s 100% environment, even if that’s the answer that would make us feel good.
Furthermore, I married a black African from Cameroon (see photo) because she's brilliant. Just because groups have tendencies doesn't mean that all the individuals in that group have those tendencies.
True racists don't allow for exceptions. In their brains, Jews are always smart, blacks are always stupid. Their mind is closed. They'll struggle to admit, for example, that Barack Obama's Kenyan father was smarter than many/most Jews.
Lastly, please study epigenetics. I may have to write a book about epigenetics because it's such an important topic that most people don't know anything about.
The notion that DNA is immutable is a 20th-century idea. In this century, thanks to epigenetics, we are learning that DNA is incredibly flexible and fast changing.
So just because a group (or an individual) has “undesirable” DNA doesn’t doom it for eternity or even a lifetime.
DNA gives us tendencies but it doesn’t determine our fate.
Disclosure: the publisher of Black Brain, White Brain, gave me a free copy of the book to do an honest review. They probably regret doing that!

What a necessary book this is! Gavin Evans is painstaking in examining and demolishing a slew of pseudo-scientific underpinnings for racism. He also “outs” a range of highly respected Nobel prize winners, wartime heroes and others writing in prestigious journals. What hurts is to see how easily white people like me can go from fighting against racism to confusing its outcomes with its causes. Maybe you can relate to this anecdote on page 31:
I put off reading it, thinking “I already know all that white people are smarter than blacks stuff is racist nonsense.” Nothing like summer holidays to get to the reading I’d put off earlier, and I am glad I did, because he traces the insidious tentacles of this thinking across the globe and across the centuries in a way from which few if any are immune. In the end he shows conclusively that the observable inequalities between black and white in today’s world are the consequences of racially based allocation of resources and opportunities, and not the source of these differences.
The first half of the book for me is the most powerful and the easiest read, where he first gives an excellent summary of the African roots of Homo sapiens – in the process demolishing the beer-fuelled “Africa has produced nothing of worth” assertion above - and then dissects the origins of race and racism in western culture. The latter half does a very thorough job of demolishing racist science’s claims of a genetic basis for race differences in intelligence, along the way cutting IQ testing firmly down to size. Necessary, as the first half explains, because of the insidious way that racial thinking rests ultimately on some twisted racial genetic smoke and mirror nonsense. But it gets quite tortuous going through the details of IQ testing unless you like that stuff.
The hard work is in disentangling the “nature/nurture” debate as it applies to racial differences and the way the current global power distribution justifies itself. Essentially, he is saying this erroneous belief is more common than most liberal-minded white people like to admit: that black people are poorer and less powerful in the world than whites because in some way they are inherently inferior. He quotes a wide range of apparently “realistic” observation of racial differences by “respectable” commentators and traces each one down to its roots in ugly blaming of the victims of slavery, colonialism and racism.
This is a book I recommend you read, whatever the colour of your skin.
[often after the third beer] “Okay, listen, I’m not a racist or anything, but can you just explain to me why Africa has produced nothing of worth? I mean, it is something in their culture, or does it go deeper?”

This is the book for which I've been waiting. Gavin Evans marshals the archaeological and genetic evidence to demonstrate convincingly that behaviorally-modern humans emerged in Africa before the species migrated to the rest of the world. He then brings the story forward to the present day, reviewing and debunking the arguments that inherent differences in intelligence exist among different racial groups (assuming that "race" can even be clearly defined), in particular drawing attention to that most measures of IQ don't take into account the full range of human mental abilities, nor do they consider environmental and cultural explanations. I will fault Evans for slapping the "racist" label on Steven Pinker, Nicholas Wade, and others who don't share his precise scientific worldview (although some he mentions do merit the label, due to the political ideology that clearly influenced their research). Otherwise, this is a well-written, convincing tome that cuts through the faulty studies and public misperceptions to show that human intelligence, while enabling vast technological and cultural advancements over the millennia, has remained fundamentally unchanged since it first emerged perhaps as much as 100,000 years (or more) ago in Africa.

This excellent book is a masterful debunking of the racist belief that black people are innately less intelligent than whites and Asians. I congratulate the author, an academic, on his well-written and articulate text, which is erudite in its analysis and incisive in its arguments while being very easy to read. He starts with an account of the cultural achievements of the African continent which have long been ignored or wilfully misinterpreted - to the extent that in Rhodesia under white rule, the ruins of Great Zimbabwe were considered 'too sophisticated' to be the work of Africans. He also shows how the promoters of this unsavoury myth have suppressed data or, more insidiously, distorted it to fit with their preconceptions and that this deceit can also be detected behind the development and interpretation of IQ testing. This is an important book and deserved to be widely read - as the publishers proclaim on the cover, it should be required reading in every home, school and university.

Like the author I too grew up in apartheid SA and so am as acutely aware of how insidious racism is, especially when cloaked in the 'respectability' of faux-science. I like that the author does not hide where he is coming from and that he calls out those that would cloak their prejudices in cherry-picked statistics by name. His analysis of why these frauds are listened to is enlightening, particularly in the age of Trump and the growth of the alt-right.
This is a highly readable book and I found myself enlightened in every chapter. The truth is that the world has become too complex for even a well-read person to keep apace with the growth in scientific knowledge and we need books like this meticulously researched but written in an accessible style. 'Black brain, White brain' should be read by everyone.

Gavin Evans threw quite a few old thoughts through the window with this book. IQ is definitely not based on colour stand out the most. There is numerous elements determining a persons IQ. No doubt about the validity of everything he wrote. Nothing he said is based only on assumptions, he did a lot of research. At times it really become tedious to read of yet another quoted research.
But... a must to read for every parent, every teacher and every person working with children.

This is an important and well-argued book, which lays out the history of race-based science and pseudoscience, and reveals the racism at the heart of much social theory. Particularly strong on demolishing much of the nonsense surrounding IQ tests.
