Nuestra Culpa: collective guilt as a predictor for reparation for historical wrongdoing

Three studies examined the hypothesis that collective guilt and shame have different consequences for reparation. In 2 longitudinal studies, the ingroup was nonindigenous Chileans (Study 1: N = 124/120, lag = 8 weeks; Study 2: N = 247/137, lag = 6 months), and the outgroup was Chile's largest indigenous group, the Mapuche. In both studies, it was found that collective guilt predicted reparation attitudes longitudinally. Collective shame had only cross-sectional associations with reparation and no direct longitudinal effects. In Study 2, collective shame moderated the longitudinal effects of collective guilt such that the effects of guilt were stronger for low-shame respondents. In Study 3 (N = 193 nonindigenous Chileans), the cross-sectional relationships among guilt, shame, and reparation attitudes were replicated. The relationship between shame and reparation attitudes was mediated by a desire to improve the ingroup's reputation
