There are marked race differences in physical attractiveness among women, but not among men. Why?
Add Health measures the physical attractiveness of its respondents both objectively and subjectively. At the end of each interview, the interviewer rates the physical attractiveness of the respondent objectively on the following five-point scale: 1 = very unattractive, 2 = unattractive, 3 = about average, 4 = attractive, 5 = very attractive. The physical attractiveness of each Add Health respondent is measured 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.
Recall that women on average are more physically attractive than men. So women of all races are on average more physically attractive than the “average” Add Health respondent, except for black women. As the following graph shows, black women are statistically no different from the “average” Add Health respondent, and far less attractive than white, Asian, and Native American women.
