Shame
Reliance on mutual aid is a distinctive characteristic of human biology. Consequently, a central adaptive problem for our ancestors was the potential or actual spread of reputationally damaging information about the self – information that would decrease the inclination of other group members to render assistance. The emotion of shame appears to be the solution engineered by natural selection to defend against this threat. The existing evidence suggests that shame is a neurocomputational program that orchestrates various elements of the cognitive architecture in the service of (i) deterring the individual from making choices wherein the personal benefits are exceeded by the prospective costs of being devalued by others, (ii) preventing negative information about the self from reaching others, and (iii) minimizing the adverse effects of social devaluation when it occurs. The flow of costs (e.g., punishment) and benefits (e.g., income, aid during times of hardship) in human societies is regulated to an important extent by this interlinked psychology of social evaluation and shame (as well as other social emotions). For example, the intensity of shame that laypeople express at the prospect of committing each of various offenses closely matches the intensity of the actual offense-specific punishments called for by criminal laws, including modern laws and ancient laws that are millennia old. Because shame, like pain, causes personal suffering and sometimes leads to hostile behavior, shame has been termed a “maladaptive” and “ugly” emotion. However, an evolutionary psychological analysis suggests that the shame system is elegantly designed to deter injurious choices and make the best of a bad situation.
