Satoshi Kanazawa Causes Firestorm After Claiming Black Women Are Less Attractive

Psychology Today blogger Satoshi Kanazawa sparked a firestorm with his latest posting entitled, “A Look at the Hard Truths About Human Nature.”

In it, the evolutionary psychologist at the London School of Economics argues that black women are less physically attractive than other women. The article was quickly removed from the site, but not before screenshots made their way onto BuzzFeed. Some excerpts:

What accounts for the markedly lower average level of physical attractiveness among black women? Black women are on average much heavier than nonblack women. The mean body-mass index (BMI) at Wave III is 28.5 among black women and 26.1 among nonblack women. (Black and nonblack men do not differ in BMI: 27.0 vs. 26.9) However, this is not the reason black women are less physically attractive than nonblack women. Black women have lower average level of physical attractiveness net of BMI. Nor can the race difference in intelligence (and the positive association between intelligence and physical attractiveness) account for the race difference in physical attractiveness among women. Black women are still less physically attractive than nonblack women net of BMI and intelligence. Net of intelligence, black men are significantly more physically attractive than nonblack men.

The only thing I can think of that might potentially explain the lower average level of physical attractiveness among black women is testosterone. Africans on average have higher levels of testosterone than other races, and testosterone, being an androgen (male hormone), affects the physical attractiveness of men and women differently. Men with higher levels of testosterone have more masculine features and are therefore more (more…)

Liberalism, Atheism, Male Sexual Exclusivity Linked To IQ

The IQ differences are statistically significant, but experts say the data shouldn't be used to stereotype or make assumptions.

Political, religious and sexual behaviors may be reflections of intelligence, a new study finds.

Evolutionary psychologist Satoshi Kanazawa at the the London School of Economics and Political Science correlated data on these behaviors with IQ from a large national U.S. sample and found that, on average, people who identified as liberal and atheist had higher IQs. This applied also to sexual exclusivity in men, but not in women. The findings will be published in the March 2010 issue of Social Psychology Quarterly.

The IQ differences, while statistically significant, are not stunning — on the order of 6 to 11 points — and the data should not be used to stereotype or make assumptions about people, experts say. But they show how certain patterns of identifying with particular ideologies develop, and how some people’s behaviors come to be.
