Taking charge and stepping in: Individuals who punish are rewarded with prestige and dominance

Abstract

A hallmark of human societies is the scale at which we cooperate with many others, even when they are not closely genetically related to us. One proposed mechanism that helps explain why we cooperate is punishment; cooperation may pay and proliferate if those who free ride on the cooperation of others are punished. Yet this ‘solution’ raises another puzzle of its own: Who will bear the costs of punishing? While the deterrence of free-riders via punishment serves collective interests, presumably any single individual—who has no direct incentive to punish—is better off letting others pay the costs of punishment. However, emerging theory and evidence indicate that, while punishment may at times be a costly act, certain individuals are better able to ‘afford’ to pay the price of punishment and are often consequentially rewarded with fitness-enhancing reputation benefits. Synthesizing across these latest lines of research, we propose a novel framework that considers how high status individuals—that is, individuals with greater prestige or dominance—enjoy lower punishment costs. These individuals are thus more willing to punish, and through their punitive action can in turn reap reputational rewards by further gaining more prestige or dominance. These reputational gains, which work in concert to promote the social success of punishers, recoup the costs of punishing. Together, these lines of work suggest that while punishment is often assumed to be altruistic, it need not always depend on altruism, and motivations to punish may at times be self-interested and driven (whether consciously or unconsciously) by reputational benefits.
