Even unaffected bystanders punish norm violations at personal cost.

Evidence

Almost two-thirds of the third parties indeed punished the violation of the distribution norm and their punishment increased the more the norm was violated. Likewise, up to roughly 60% of the third parties punished violations of the cooperation norm. Thus, our results show that the notion of strong reciprocity extends to the sanctioning behavior of ”unaffected” third parties. — Ernst Fehr, Third-Party Punishment and Social Norms, 2
