Social emotions appear to be behavior-regulating programs built by natural selection to solve adaptive problems in the domain of social valuation—the disposition to attend to, associate with, defer to, and aid target individuals based on their probable contributions to the fitness of the valuer. For example, shame functions to prevent and mitigate the costs of being socially devalued by others, whereas anger functions to correct those people who attach insufficient weight to the welfare of the self. Here we review theory and evidence suggesting that social emotions such as guilt, gratitude, anger, pride, shame, sadness, and envy are all governed by a common grammar of social valuation even when each emotion has its own distinct adaptive function and structure. We also provide evidence that social emotions and social valuation operate with a substantial degree of universality across cultures. This emotion-valuation constellation appears to shape human sociality through interpersonal interactions. Expanding upon this, we explore how signatures of this constellation may be evident in two spheres of human sociality: personality and the criminal justice system.
