The potential role of descriptive and dynamic norms in promoting climate change advocacy

Abstract

AbstractPolitical advocacy is arguably the most powerful form of action that citizens concerned about climate change can take. One motivator for political advocacy is the perception that there is a social norm (i.e. inherently understood social rules and standards that serve to guide social behaviors) for doing so. Using nationally representative survey data (N = 1303), we examined the association of three types of social norms—descriptive norms (i.e. perceptions about how many other people perform a behavior), retrospective and prospective dynamic norms (i.e. perceptions that a behavior has become more or less common in the past or will in the future)—with intentions to engage in political advocacy in the upcoming year and past advocacy. We found that descriptive norms and prospective dynamic norms were positively related to advocacy intentions, while only prospective dynamic norms were positively related to past advocacy (retrospective dynamic norms were negatively related to both outcomes, contrary to our theorized direction). Furthermore, we examined whether the relationship between norms and intentions/behaviors differed based on political party identification and four potential mediators of this relationship: identification with climate activists; collective efficacy (i.e. the belief that people can engage in climate advocacy and that it will make a difference); collective response efficacy (i.e. beliefs about the results of advocacy); and injunctive norms (i.e. perceptions of others’ approval of advocacy). In the moderated mediation models, we found that party identification moderated the relationships between descriptive norms and prospective dynamic norms and advocacy intention, while retrospective dynamic norms were not related as theorized. These relationships were mediated by identification with climate activists and collective efficacy as well as by injunctive norms in the case of descriptive norms. Party identification also moderated the relationship between descriptive norms and past advocacy; this relationship was mediated by identification with climate activists and injunctive norms. Taken together, these findings underscore the potential importance of perceived descriptive norms and prospective dynamic norms on political advocacy to address climate change, extending both well-established and emerging research and providing insights useful for academics and practitioners alike.
