The physical attractiveness of each Add Health respondent is [rated] three times by three different interviewers over seven years.
From these three scores, I can compute the latent "physical attractiveness factor" by a statistical procedure called factor analysis. Factor analysis has the added advantage of eliminating all random measurement errors that are inherent in any scientific measurement. The latent physical attractiveness factor has a mean of 0 and a standard deviation of 1.
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.Inconveniently for black men and Kanazawa, the real world does not control for intelligence. Further, if the association between intelligence and physical attractiveness rests on some underlying "good genes" factor, it makes little sense to try to "control" for intelligence when comparing races. The intelligence and attractiveness of someone with average genes for his race are what they are.
