Cooperation in Networked Collective-Action Groups
Norms, typically enforced via sanctions, are key to resolving collective-action problems. But it is often impossible to know what each individual member is contributing to group efforts and enforce cooperation accordingly. Especially as group size increases, people commonly have access to the behaviors of—and can sanction—only those to whom they are tied in a broader network. Here we integrate two streams of research: one conceptualizing ties in …
Resource asymmetry reduces generosity and paying forward generosity, among the resource-advantaged and disadvantaged
How can I help you? Multiple resource availability promotes generosity with low-value (but not high-value) resources
People commonly possess multiple, differentially-valued resources they can use to benefit those in need: contributing money, volunteering time, donating unwanted possessions, posting on social media to raise awareness, and more. But the majority of experimental work on generosity and helping behavior has studied giving when only a single valuable resource is available to give. This project considers: when people have multiple, differentially-valu…
Better together
Birds of Different Feathers Cooperate Together
Many evolutionary models of cooperation assume that altruists possess telltale signs of disposition that they use to find and selectively associate with each other. Prior research finds that people can detect these signs of altruism in strangers, but we do not yet know whether this results in altruism homophily. We argue that dispositions should matter less in repeated interactions, where behavior is based on reciprocity. As a consequence, we sho…
Hidden Paths from Morality to Cooperation
Classic sociological solutions to cooperation problems were rooted in the moral judgments group members make about one another’s behaviors, but more recent research on prosocial behaviors has largely ignored this foundational work. Here, we extend theoretical accounts of the social effect of moral judgments. Where scholars have emphasized the roles of moral judgments in clarifying moral boundaries and punishing deviants, we present two less intui…
