Gossip or confrontation? Sanctioning environmental norm violations and the reputation of punishers

Prior research has shown that peer punishment can promote norm adherence, but people's perceptions of whether and how environmentally harmful behaviors should be sanctioned remain underexplored. Shedding light on this question is important because normative consensus regarding environmental behaviors varies considerably, from strong and widely shared norms to weak or absent norms. Study 1 documents this normative variation by mapping norm perceptions across 18 environmentally friendly and harmful behaviors. Studies 2 and 3 examine the perceived appropriateness of different informal sanctions (i.e., gossip, exclusion, and confrontation) against environmentally harmful behaviors seen as norm violations. Further, we test how these sanctions affect punishers' reputation across several dimensions (i.e., warmth, morality, competence, and aggressiveness), as well as third parties' decisions to trust punishers. Results conceptually replicate previous work in the environmental domain by showing that more severe environmental norm violations led to higher perceived appropriateness of informal sanctions. Extending previous work, we also found that (1) gossip was perceived as the most appropriate informal sanction for moderate violations, while confrontation was perceived as most appropriate for severe violations, and that (2) punishers who confronted environmental norm breakers received a more favorable reputation and greater trust compared to those who responded with gossip or exclusion. This research suggests that informal sanctions are appropriate methods for addressing environmental norm violations, and their reputational consequences depend on the type of sanction used. • A new comprehensive scenario pool of environmental norm violations • Severe norm violations increase the perceived appropriateness of informal sanctions • Gossip is seen as more appropriate for moderate violations • Confrontation is seen as more appropriate for severe violations • Confronters receive better reputation than those using other informal sanctions
