Isto explica MUITA coisa (se ao menos for verdade)

So, yes, the stereotypes appear to be true: We males are a gender of fragile egos in search of a pretty face and are threatened by brains or success that exceeds our own. Women, on the other hand, care more about how men think and perform, and they don't mind being outdone on those scores.

Another clear gender divide, this one less expected, emerged in our findings on racial preferences, reported in a forthcoming article in the Review of Economic Studies. Women of all the races we studied revealed a strong preference for men of their own race: White women were more likely to choose white men; black women preferred black men; East Asian women preferred East Asian men; Hispanic women preferred Hispanic men. But men don't seem to discriminate based on race when it comes to dating. A woman's race had no effect on the men's choices.
Two wrinkles on this: We found no evidence of the stereotype of a white male preference for East Asian women. However, we also found that East Asian women did not discriminate against white men (only against black and Hispanic men). As a result, the white man-Asian woman pairing was the most common form of interracial dating—but because of the women's neutrality, not the men's pronounced preference.
