Awe is an emotional response to perceptually vast stimuli that transcend current frames of reference. Guided by conceptual analyses of awe as a collective emotion, across 5 studies (N = 2,078) we tested the hypothesis that awe can result in a diminishment of the individual self and its concerns, and increase prosocial behavior. In a representative national sample (Study 1), dispositional tendencies to experience awe predicted greater generosity in an economic game above and beyond other prosocial emotions (e.g., compassion). In follow-up experiments, inductions of awe (relative to various control states) increased ethical decision-making (Study 2), generosity (Study 3), and prosocial values (Study 4). Finally, a naturalistic induction of awe in which participants stood in a grove of towering trees enhanced prosocial helping behavior and decreased entitlement compared to participants in a control condition (Study 5). Mediational data demonstrate that the effects of awe on prosociality are explained, in part, by feelings of a small self. These findings indicate that awe may help situate individuals within broader social contexts and enhance collective concern.

Americans' attitudes about the environment are highly polarized, but it is unclear why this is the case. We conducted five studies to examine this issue. Studies 1a and 1b demonstrated that liberals, but not conservatives, view the environment in moral terms and that this tendency partially explains the relation between political ideology and environmental attitudes. Content analyses of newspaper op-eds (Study 2a) and public-service announcements (Study 2b) found that contemporary environmental discourse is based largely on moral concerns related to harm and care, which are more deeply held by liberals than by conservatives. However, we found that reframing proenvironmental rhetoric in terms of purity, a moral value resonating primarily among conservatives, largely eliminated the difference between liberals' and conservatives' environmental attitudes (Study 3). These results establish the importance of moralization as a cause of polarization on environmental attitudes and suggest that reframing environmental discourse in different moral terms can reduce the gap between liberals and conservatives in environmental concern.

The widespread existence of cooperation is difficult to explain because individuals face strong incentives to exploit the cooperative tendencies of others. In the research reported here, we examined how the spread of reputational information through gossip promotes cooperation in mixed-motive settings. Results showed that individuals readily communicated reputational information about others, and recipients used this information to selectively interact with cooperative individuals and ostracize those who had behaved selfishly, which enabled group members to contribute to the public good with reduced threat of exploitation. Additionally, ostracized individuals responded to exclusion by subsequently cooperating at levels comparable to those who were not ostracized. These results suggest that the spread of reputational information through gossip can mitigate egoistic behavior by facilitating partner selection, thereby helping to solve the problem of cooperation even in noniterated interactions.
