This study sought to identify the conditions facilitating the recognition of a social group’s past misdeeds among its members. Such recognition entails a threat to group members’ social identity, potentially triggering defensive strategies, such as denying these misdeeds, not experiencing collective guilt and shame, opposing reparative actions, and derogating the victim group’s members. As collective rituals, public apologies performed by an official representative should allow group members to acknowledge the harm done while maintaining a positive social identity, therefore alleviating the need for such defensive strategies. We carried out an experimental study based on a 2 (Apologies vs. No apologies) x 2 (Continued suffering vs. No continued suffering) + 1 (Control) design, with Belgian participants (N = 164). In all conditions, participants were reminded of the atrocities committed during the first years of the Belgian colonization of Congo. This description was followed by a short statement about the suffering that Congolese people still endured (Continued suffering condition) or none (No continued suffering), then by a transcript of public apologies pronounced by Belgium’s Foreign Affairs Minister in the Apologies condition, or none (No apologies). Results revealed that Belgian participants’ attitudes and behavioural intentions towards the Congolese were the most positive when both apologies and the victims’ continued suffering were reunited. A mediation analysis further demonstrated that differences in levels of racism and in support for reparation were mediated by representations of the ingroup’s past. ; info:eu-repo/semantics/published
