When the specter of the past haunts current groups: Psychological antecedents of historical blame.

Groups have committed historical wrongs (e.g., genocide, slavery). We investigated why people blame current groups who were not involved in the original historical wrong for the actions of their predecessors who committed these wrongs and are no longer alive. Current models of individual and group blame overlook the dimension of time and therefore have difficulty explaining this phenomenon using their existing criteria like causality, intentionality, or preventability. We hypothesized that factors that help psychologically bridge the past and present, like perceiving higher (a) connectedness between past and present perpetrator groups, (b) continued privilege of perpetrator groups, (c) continued harm of victim groups, and (d) unfulfilled forward obligations of perpetrator groups would facilitate higher blame judgments against current groups for the past. In two repeated-measures surveys using real events (N1 = 518, N2 = 495) and two conjoint experiments using hypothetical events (N3 = 598, N4 = 605), we find correlational and causal evidence for our hypotheses. These factors link present groups to their past and cause more historical blame and support for compensation policies. This work brings the dimension of time into theories of blame, uncovers overlooked criteria for blame judgments, and questions the assumptions of existing blame models. Additionally, it helps us understand the psychological processes undergirding intergroup relations and historical narratives mired in historical conflict. Our work provides psychological insight into the debates on intergenerational justice by suggesting methods people can use to ameliorate the psychological legacies of historical wrongs and atrocities.
