The great idiot of social science...
PZ Myers[1]

Satoshi Kanazawa (1962–) is an evolutionary psychologist[2] at the London School of Economics and exactly the kind of researcher who makes evolutionary psychology look bad. So say thirty-five leading evolutionary psychologists, at least.[3] His chief weapons are causalation, p-value fishing, bad data analysis, bigotry, and surprise. Psychology Today decided to throw standards out the window and gave him a blog, which was ironically named The Scientific Fundamentalist. It later got pulled from the site after he posted some racist drivel dressed up in pseudoscientific language.

Savanna principle[edit]

Much of Kanazawa's work revolves around his so-called "Savanna principle," which applies the Savanna hypothesis to evolutionary psychology. The basic idea here is that early Homo sapiens became dominant through adapting to the environment of the African Savanna, thus, our minds and brains are adapted to that environment. However, Kanazawa's explanation of the anthropology behind the Savanna hypothesis is sketchy, especially when it comes to his hypotheses about intelligence.[4] He also fails to take into account that biological adaptation has not stopped since humans began to spread throughout the globe. He attempts to build on the seminal work of Leda Cosmides and John Tooby, who describe how various aspects of the mind are adapted to earlier environments, but instead just massively overstates their conclusions and takes it to ridiculous extremes. The Savanna, then, becomes something he can shoehorn much of his research into.

Stand back, this is science![edit]

Sensational statement that will piss people off plus contrived post hoc rationalization equals amazing insight of Satoshi Kanazawa!

Asians aren't creative[edit]

One of his earlier "brilliant" ideas was an attempt to demonstrate that Asian culture inhibited creativity. Besides the fact that this is flawed from the start because it lumps all Asian cultures together, two of his measures were the number of each region's Nobel prizes awarded and the height of its skyscrapers. Besides failing to pass the smell test, as Geoffrey Miller points out, these criteria would predict that the US would have never overtaken Europe in terms of science or wealth if one looks at the same statistics from circa one hundred years ago.[6] Kanazawa must have fallen asleep through the unit on construct validityWikipedia during his research methods course.

Evolution makes you hot[edit]

In the mid-2000s, Kanazawa published a number of papers looking at birth rates and compared them to ratings of beauty and the occupation of the subjects. He found that subjects that were ranked more beautiful had more children and that various occupations tended to have different birth rates for boys and girls. This is where Columbia statistician Andrew Gelman came in and reviewed his work, finding that the statistical models Kanazawa used overstated the effects he found.[7][8][9] Never one to be modest or conservative in his conclusions, Kanazawa continued shoehorning some blatherskite about women evolving to be more beautiful into his findings. This eventually led Gelman to dub him the "Fenimore Cooper of sociobiology."[10] Gelman also uses his work as an example of bad statistics in teaching undergraduate courses.

African people are just stupid[edit]

Kanazawa then went completely off the rails and published some studies that read like The Bell Curve with even less tip-toeing around the racism. Why is Africa a third-world shithole? Because Africans are genetically predisposed to stupidity! All he did was take some comparisons of IQ, wealth, and health data, shoehorn in some Savanna principle, and declare Africans to be genetically inferior. That's not reminiscent of anything, nothing at all. Besides the dubiousness of using IQ in this way,[11] Kanazawa, of course, selectively ignores research showing the cause-and-effect to be the opposite way around.[12][13] Another study he conducted on cross-country differences in intelligence used a model that assumed a flat earth.[14]

Atheists and liberals are smarter[edit]

This time around, Kanazawa attempted to demonstrate the intellectual superiority of atheists and liberals. Besides all of the other dubious methodology, one of the studies in the pair he published didn't even use an IQ test — he simply extrapolated "intelligence" from a verbal test.[15][16][17] And this all goes back to our Savanna ancestors, of course!

Black girls are ugly (or, blog whitewashing)[edit]

For some reason, Kanazawa didn't cause a full-blown shitstorm until a post he made to his blog in May of 2011 in which he claimed that black women were "objectively" less beautiful than those of other races. Besides the fact that "black" is not a strict category and that he didn't take into account any social confounding factors, the supposed "objective" measure was a 1-5 Likert scale with some factor analysis tomfoolery thrown in. Psychology Today decided this was over the line even for Kanazawa and scrubbed the post.[18]

Blogging nuttery[edit]

Kanazawa used his blog to whine about the "PC police" and he indulged in some rather amusing (read: deranged) flights of fancy on its pages, including Ann Coulter as president turning the Middle East into a glass crater, killing "all the feminists and hippies and liberals" (even though they're supposedly smarter, but whatevs, right?), and how much happier people would be if women stayed in the damn kitchen.[19]

So long, Satoshi[edit]

In the wake of his latest blogging incident, over 120,000 students of the University of London Union Senate subsequently unanimously voted to condemn his research.[20] In June of 2011, Psychology Today canned Kanazawa for good in reaction to the "black women are ugly" post.[21] In September, LSE suspended Kanazawa from publishing any material in non-peer reviewed journals for a year and he issued an apology stating that the post was "flawed."[22][23]
