"Does social influence exerted through role modeling of collective action impact social change in contexts that are not conducive to collective action, such as long-lasting violent conflicts? We examined this question in two field experiments in the Eastern Democratic Republic of Congo. We created t ... wo versions of an episode of an existing media intervention (a show aiming to promote positive social change), in which fictional characters either planned collective action (role modeling condition), or did not plan action (control condition) to address grievances. In Study 1, role modeling affected individual-level outcomes: it increased perceived collective efficacy and willingness to take action, but exacerbated intergroup attitudes and reduced tolerance. Study 2 tested the influence of role modeling on a group-level outcome (group discussions). Discussions following the role modeling show focused less on grievances, and included more positive lessons of the show, as well as more statements about collective efficacy and collective action. The findings highlight the influence of role modeling of collective action through media on efficacy and action for social change, but caution against unintended consequences on intergroup attitudes."

"The present study (N= 1074) examined the impact of a theory-driven media intervention aimed atviolence prevention and intergroup reconciliation in Burundi. We used a novel methodology utilizing audio-based surveys to assess attitudes related to intergroup conflict and reconciliation among community ... members. We conducted a propensity score analysis to estimate the causal effects ofthe intervention by examining differences between listeners and non-listeners of the radio dramas. The results indicated a positive effect of the intervention on several social psychological outcomes (tolerance, in-group superiority, social distance, intergroup trust, responsibility attributions, trauma disclosure and competitive victimhood). However, listeners and non-listeners did not differ in obedience toward leaders or historical perspective taking; and the results for active bystandership, one of the main foci of the intervention, were mixed. Furthermore, the results show that the impact of theintervention sometimes depends on listeners’personal experiences of victimization." (Abstract) more
