The attractiveness “data” is itself suspect, for one thing. It consists of the subjective judgments of interviewers who were asked to rate their interviewees’ appearance. There’s no effort in the numbers to control for the interviewers’ (unstated) ethnicity, no protocol for their judgments, no reason to believe that their conclusions are in any way representative. It’s just their opinion, and different interviewers reached dramatically different conclusions about the same interviewees’ attractiveness.
Let me underscore that last bit. According to a review of the original data, most of the difference in attractiveness between individuals in the study can be explained by different interviewers “grading” the same interviewee differently.
