From: Men’s impulsivity underpins gender differences in aggressive behaviour
Gender differences in aggression. (A) Behaviour, averaged across all rounds and gender pair combinations, reveals that overall mean aggression levels were higher for men than women. (B) Overall differences in aggression between men and women reflect an interaction between aggressor and target gender. Specifically, all pairs containing at least one man behaved similarly, but women-only pairs were less aggressive (and these pairings pull down the overall average for women). (C) Aggression over time, averaged by round, shows that women only pairs (white) consistently exhibit less aggression than pairs containing at least one man (dark grey). (D) The probability of men and women initiating an escalation in aggression, averaged across mixed gender pairs, reveals a large gender difference in who is most likely to initiate an increase in aggression. Specifically, men are an order of magnitude more likely than women to raise aggression above the pair’s overall mean.
