Third-party punishment can stabilize any cultural trait within a group

Evidence

Hypothesis 3: Third-party punishment. Scholars from economics, anthropology, and biology have suggested that third-party punishment (also called moralistic reciprocity) may account for the maintenance of group norms (Binmore 1994; Hirshleifer and Rasmussen 1988) and, consequently, the similarity within groups and the differences between groups. This hypothesis proposes that humans possess a reliably developing neural encoding that compels them both to punish individuals who violate group norms (common beliefs or practices) and punish individuals who do not punish norm violators—the punishment of nonpunishers. Boyd and Richerson (1992b; see Binmore and Hirshleifer and Rasmussen for analogous results in economics) have shown that punishment can stabilize group beneficial behaviors and any other cultural trait within a group. By punishing norm violators and nonpunishers of norm violators, punishment can maintain any belief or practice ranging from such odd behaviors as wearing uncomfortable neck ties and tipping at restaurants, to charging an entrenched enemy under fire or eating the brains of dead relatives. — Joe Henrich and Robert Boyd, The Evolution of Conformist…, 117
