Abstract
Conformity is a large topic and its causes are undoubtedly heterogenous. Of the various mechanisms that contribute to conformity, I will comment on two: coordination and esteem. Game theorists have given coordination significant attention. Lewis first posited that social conventions are, roughly, particular equilibrium outcomes to recurrent coordination problems. Once the equilibrium occurs, it is, by definition, in everyone’s interest to conform. Evolutionary game theorists have explored the conditions that make a certain equilibrium likely to emerge and persist when more than one equilibrium is possible. In the first section below, I set forth one point about the nature of conformity in such settings—that there can be a strong stability to conventions in which the required behavior varies by the observable physical differences among human beings, such as sex and those that come to be associated with race. In a certain class of important games, observable personal differences work to “break symmetry,” which significantly changes the possible outcomes to the game. My aim is not to provide a particular model of conformity involving sex and race, but to illustrate the usefulness of a particular approach to model-building.
