Abstract

We report three studies which test a sexual selection hypothesis for male war heroism. Based on evolutionary theories of mate choice we hypothesize that men signal their fitness through displaying heroism in combat. First,we report the results of an archival study onUS-American soldierswho fought in WorldWar II. Wecompare proxies for reproductive success between a control sample of 449 regular veterans and 123 surviving Medal of Honor recipients of WWII. Results suggest that the heroes sired more offspring than the regular veterans. Supporting a causal link betweenwar heroismandmating success,we then report the results of two experimental studies (n’s=92 and 340).We find evidence that female participants specifically regard men more sexually attractive if they arewar heroes. This effect is absent for male participants judging female war heroes, suggesting that bravery in war is a gender specific signal. Finally, we discuss possible implications of our results.
