Collective Memories, Personal Experiences, and Inter-Group Attitudes

How do collective memories of war shape inter-group social attitudes in post-conflict societies? Can the legacy of wartime violence hinder reconciliation for years or even decades after the conflict ends? While prior research shows that war memories influence a range of political processes and outcomes, their effects on how members of formerly opposing groups perceive one another remain underexplored. To address this gap, I conducted a survey experiment in post-war Bosnia, investigating whether the activation of these memories affects hostility toward out-groups. The results show that making war memories salient intensifies hostility, especially among individuals who personally experienced violence during the war. These findings suggest that deeply ingrained war memories pose a significant barrier to reconciliation, but their impact may gradually diminish through the generational replacement of the wartime population.
