Impulsive, deceitful, narcissistic, and exploitative men have more success with women, Mason Inman writes for the New Scientist. Although they risk social alienation, men who exhibit the “dark triad” personality traits–described as somewhere between narcissistic and psychopathic behavior–have more prolific sex lives and are evolutionarily more successful.
The correlation between “dark triad” personality traits and active sex lives didn’t hold true for women, but mean girls have unique methods of competition. According to another article in the New Scientist, women learn more subtle modes of social competition than their male counterparts. While little boys try to grab or chase objects of their desire, a study from Emmanuel College in Boston found that young girls learn to harness “the pain of social exclusion” in order to get what they want.
