We’ve all been there: we were introduced to that really good looking guy at a party or at the club or some other social setting, and even though he was hotter than a rooster in socks the more he talked the more turned off you got as it became clear that he was kind of a self-focused ass. According to a study at Brunel University London this isn’t just happenstance. Rather, attractive men as a whole tend to be more selfish.

The study, titled “Bodily Attractiveness and Egalitarianism are Negatively Related in Males” and published in Evolutionary Psychology, took 125 male and female participants, scored them on generalized attractiveness measures, and then took part in an economics experiment where they were asked to share money with someone else. The results found that men who were ranked as more attractive tended to have a bias towards selfishness. The research also found that attractiveness was at least as important as wealth when it came to attitudes of altruism and egalitarianism. Interestingly, the same was not true for women.

Lead researcher Dr. Michael Price warned against taking the findings as gospel, however, saying:

The correlation between attractiveness and selfishness was nowhere close to being perfect, and many very attractive men will also be very altruistic and egalitarian.

Additionally, these attitudes tended to be subconscious, and being made aware of their biases helped men act against them and engage in more generosity.
