Abstract: There is abundant evidence that sense of humor is a sexuality selected trait, signalling underlying mate quality and intelligence. Consistent with sexual selection and mental fitness indicator theories, women view humor production ability as more important when choosing a mate. However, it is not clear if men actually possess higher humor abilities than women. We offer the first comprehensive quantitative meta-analysis on the topic, aimed at measuring the magnitude of such differences, if present. We included studies where participants identified as male or female created humor output that was assessed for funniness by independent raters who were blind to any characteristics of the subjects. Our meta-analysis includes 36 effect sizes from 28 studies (N = 5057, 67% women, including college and non-college students). Twenty of the 36 effect sizes, accounting for 61% of the participants, were not previously published. Results based on random-effects model revealed that men’s humor output was rated as funnier than women’s, with a combined effect size d = 0.321. Results were robust across various moderators and study characteristics, and multiple tests indicated that publication bias is unlikely. Overall, the results are consistent with the signalling hypothesis, and the view that humor is a sexually selected trait.
