Humans have a long history of intergroup conflict › Identify easily with groups › Will work hard to defend their group A lot of research has been done on group behavior in humans › Has found some interesting things about men
Men tend to be more group oriented than women Men benefit from being competitive › Indigenous societies › Street gangs Maybe humanity’s history of group conflict has influenced the evolution of men › The male-warrior hypothesis
Men more intergroup oriented than women Predicts that men will increase altruistic group contributions in competitive situations more than women will › Van Vugt et al. are seeking to provide empirical support for this prediction
120 university undergraduates (33% male) 6 person groups › No interaction with group members IV: Competition › Group Told performance will be compared with other universities › Individual Told performance being analyzed on an individual level
Given £2 › can keep or contribute all of it to the group If group as a whole contributes £8 or more (at least 4/6 contribute) › each group member given £4 If less than £8 contributed › no bonus money DV: Did individual contribute?
Design the same as Experiment 1 except: › Participants given £3 (300 pence) Total needed for bonus money is £12 Bonus money is £5 › Participants can give any amount DV: Amount individual contributes
Same design as experiment 2 except: › 6 iterations of the task (DV = mean contribution) After completing trials participants took a questionnaire on group identification › Measured how strong group identification was
Competition Predicted Group Identification for males
Men identify more strongly with their group Men contribute more in competitive situations than in non-competitive situations Women unaffected by competition › But contribute more overall Supports male-warrior hypothesis
They note : › Limited money quantities › Possibility of insufficient competition WEIRD population (all college students) Others?
Does the male-warrior hypothesis predict that men are more competitive than women?
Men and women contributed pretty equally in competitive conditions › Men just contribute less in non-competitive ones Male-warrior hypothesis says that men more influenced by competition › not that they contribute more in competitive situations
If the only consistent difference between men and women is that men contribute less in non-competitive situations, is this really a male-warrior? Or are men just lazy outside of competition? Is this a difference that matters?
The loyalty foundation of morality “The male mind appears to be innately tribal” (pg. 162) Loyalty is to the group for men And to individuals for women Do you agree?
