 While Kanazawa claims that the former error is "merely linguistic" and that he addressed the latter two in his initial article, Gelman maintains that his original criticism remains valid.In May 2011, he published an article in "Psychology Today" that explored why black women had been rated less attractive than those of other races in the National Longitudinal Study of Adolescent Health.Subsequent critical independent analysis of the results showed that the difference in assessed attractiveness held for three of the four data sets in the National Longitudinal Study of Adolescent Health and that there was only a statistically significant race difference in younger women and that it disappeared by early adulthood.
