...aren't crazy:

For the study, more than 1,000 adult participants were asked to rate the sexual attractiveness of hundreds of images of the opposite sex. The images showed people in displays of happiness (broad smiles), pride (raised head, puffed-up chest), and shame (lowered head, averted eyes).

Who did the gals go for? The study showed they preferred guys who looked proud or moody and ashamed. But the guys were most sexually attracted to women who looked happy, and least attracted to those who appeared proud and confident.

Tracy and her co-author, graduate student Alec Beall, said women may have evolved to find proud guys attractive because pride implies status, competence and an ability to provide for a partner and offspring. And previous research has linked smiling with a lack of dominance—which men seem to find attractive in a mate, but not the other way around.

So, nice guys, now you don't just have bitter personal experience to point to when you complain about women going for assholes. Science is on your side too. And this new research is so depressing that it could wipe the smile right off your nice faces, making you appear moody and ashamed... which would go a long ways toward solving your problem, right?
