Shame closely tracks the threat of devaluation by others, even across cultures
Significance Prominent theories of shame hold that shame is inherently maladaptive. However, direct tests of the fit between shame and its probable target domain have not previously been conducted. Here we test the alternative hypothesis that shame, although unpleasant (like pain) serves the adaptive function of defending against the social devaluation that results when negative information reaches others by deterring actions that would lead to more devaluation than benefits, for example. If so, the intensity of shame people feel regarding a given item of negative information should track the devaluation that would happen if that item became known. Indeed, the data indicate a close match between shame intensities and audience devaluation, which suggests that shame is an adaptation. We test the theory that shame evolved as a defense against being devalued by others. By hypothesis, shame is a neurocomputational program tailored by selection to orchestrate cognition, motivation, physiology, and behavior in the service of: (i) deterring the individual from making choices where the prospective costs of devaluation exceed the benefits, (ii) preventing negative information about the self from reaching others, and (iii) minimizing the adverse effects of devaluation when it occurs. Because the unnecessary activation of a defense is costly, the shame system should estimate the magnitude of the devaluative threat and use those estimates to cost effectively calibrate its activation: Traits or actions that elicit more negative evaluations from others should elicit more shame. As predicted, shame closely tracks the threat of devaluation in the United States (r .69) India (r .79) and Israel (r .67) Moreover, shame in each country strongly tracks devaluation in the others, suggesting that shame and devaluation are informed by a common species wide logic of social valuation. The shame devaluation link is also specific: Sadness and anxiety emotions that coactivate with shame fail to track devaluation. To our knowledge, this constitutes the first empirical demonstration of a close, specific match between shame and devaluation within and across cultures.
