The Evolution of Competition

Human competition is, at least partially, responsible for some of the transcended achievements of the species (walking on the moon, the polio vaccine, etc.), but the forces unleashed by competition have also led to profound human suffering (warfare, domination of one group by another group, etc.). In this article, the authors approach competition from an evolutionary perspective, applying Darwin’s theories of natural and sexual selection to understand better the nature of human competition. From the perspective of evolutionary psychology, humans engage in competition to gain resources, including status, food, and mating opportunities. Males tend to engage in more overt and aggressive forms of competition than females, but both sexes desire access to material and cultural goods associated with reproductive fitness. In the last roughly seventy years, the nature of men’s competition has transformed dramatically leading to declines in both within and between-group violence. As developed societies have succeeded in suppressing more overt and destructive forms of male–male competition, men attempt to gain status through occupational success, cognitive sophistication, moral signaling, and other relatively nonviolent behaviors. In this sense, men’s and women’s competition is more similar than it was a century ago. However, women’s competition is still less visible and relies on more indirect mechanisms (e.g., spreading gossip, subtle use of body language). For this reason, female–female competition has attracted less study than male–male competition. Fortunately, in the last decade, psychologists have partially redressed this imbalance.
