Co-Operative Punishment Cements Social Cohesion

Co-Operative Punishment Cements Social Cohesion

Most current attempts to explain the evolution—through individual selection—of pro-social behavior (i.e. behavior that favors the group) that allows for cohesive societies among non related individuals, focus on altruistic punishment as its evolutionary driving force. The main theoretical problem facing this line of research is that in the exercise of altruistic punishment the benefits of punis...

Anti-social punishment can prevent the co-evolution of punishment and cooperation.

The evolution of cooperation is one of the great puzzles in evolutionary biology. Punishment has been suggested as one solution to this problem. Here punishment is generally defined as incurring a cost to inflict harm on a wrong-doer. In the presence of punishers, cooperators can gain higher payoffs than non-cooperators. Therefore cooperation may evolve as long as punishment is prevalent in the...

Social Cohesion

Investigators interested in developing a general theory of social cohesion are confronted with a complex body of work that involves various definitions of social cohesion, specialized literatures on particular dimensions of social cohesion (e.g., membership turnover, organizational commitment, categorical identifications, interpersonal attachments, network structures), and lines of inquiry focu...

Social Identity and Punishment

Third party punishment is crucial for sustaining cooperative behavior. Still, little is known about its determinants. In this paper we use laboratory experiments to investigate a long-conjectured interaction between group identification and bystanders’ punishment preferences using a novel measure of these preferences. We induce minimal groups and give a bystander the opportunity to punish the p...
