Norm enforcement may be important for resolving conflicts and promoting cooperation. However, little is known about how preferred responses to norm violations vary across cultures and across domains. In a preregistered study of 57 countries (using convenience samples of 22,863 students and non-students), we measured perceptions of the appropriateness of various responses to a violation of a cooperative norm and to atypical social behaviors. Our findings highlight both cultural universals and cultural variation. We find a universal negative relation between appropriateness ratings of norm violations and appropriateness ratings of responses in the form of confrontation, social ostracism and gossip. Moreover, we find the country variation in the appropriateness of sanctions to be consistent across different norm violations but not across different sanctions. Specifically, in those countries where use of physical confrontation and social ostracism is rated as less appropriate, gossip is rated as more appropriate.

Altruistic punishment is crucial in promoting cooperation and maintaining social fairness. The third-party punishment (TPP) game, a typical paradigm testing altruistic punishment behavior, involves individuals incurring personal costs to punish norm violations others commit. This altruistic (costly) punishment has been suggested as an adaptive trait in human evolution, influencing behaviors such as mate selection.

Over the last decades, the traditional 'Homo economicus' model has been increasingly challenged by converging evidence highlighting the critical impact of emotions on decision-making. A classic example is the perception of unfairness in the Ultimatum Game, where humans willingly sacrifice personal gains to punish fairness norm violators. While emotional mechanisms underlying such costly punishment are widely acknowledged, the distinct contributions of moral emotions, particularly anger and disgust, remain debated, partly due to methodological limitations in conventional experiments.

In simple microbial populations, the fitness effects of most selected mutations are generally taken to be constant, independent of genotype frequency. This assumption underpins predictions about evolutionary dynamics, epistatic interactions, and the maintenance of genetic diversity in populations. Here, we systematically test this assumption using beneficial mutations from early generations of the Long-Term Evolution Experiment (LTEE).

Objectives: The ability to navigate diverse social contexts, such as interacting with different individuals, is crucial across the lifespan and has implications for fraud susceptibility. However, the neural mechanisms supporting social decisions in older adults within varied social contexts remain largely unknown. This study investigated how age and partner similarity modulate neural activation and network connectivity during fairness-related decision making and whether individual differences in behavioral sensitivity to fairness norm violations correlate with neural activities.

Cultures, such as Japan, are characterized by tighter or more rigid norms than others, like the United States. However, the mechanism underlying this cultural difference remains unclear. We tested the hypothesis that individuals carrying genetic polymorphisms linked to cultural learning, particularly the 7- or 2-repeat variable number of tandem repeat variants of the dopamine D4 receptor gene, DRD4, would show heightened sensitivity to norm violations if they are from tight cultures but not in loose cultures.
