Are men more competitive than women?

This study uses competition diaries to see whether women and men differ in (a) what they compete over, (b) whom they compete with, and (c) their competitive tactics, including use of aggression. In Study 1, university students kept diaries of their competitive interactions during the term. Sex differences, few overall, were as follows: (a) men's diaries contained more same-sex competition, (b) women competed more about looking attractive whereas men competed more about sports, and (c) men used physical (but not verbal) aggression more frequently than women. In Study 2 strength of competition was also measured by questionnaire. Women and men felt equally competitive overall, but men felt more competitive about athletics and sexual attention whereas women felt more competitive about looking attractive. In men, but not women, competitiveness for financial success was correlated with various aspects of mating competition. Young men were more competitive than older men in a variety of domains and were also more physically and verbally aggressive, but no age difference in aggression was found for women.
