Abstract
We use techniques from evolutionary game theory to analyze the conditions under which guilt can provide individual �fitness bene�fits, and so evolve. In particular, we focus on the bene�fits of guilty apology. We consider models where actors err in an iterated prisoner's dilemma and have the option to apologize. Guilt either improves the trustworthiness of apology, or imposes a cost on actors who apologize. We analyze the stability and likelihood of evolution of such a `guilt-prone' strategy against cooperators, defectors, grim-triggers, and individuals who o�ffer fake apologies, but continue to defect. We fi�nd that in evolutionary models guilty apology is more likely to evolve in cases where actors interact repeatedly over long periods of time, where the costs of apology are low or moderate, and where guilt is hard to fake. Researchers interested in naturalized ethics, and emotion researchers, can employ these results to assess the plausibility of fuller accounts of the evolution of guilt.
