Replication Data for: Collective victimhood beliefs and conflict-related attitudes: A meta-analysis

This study conducts a meta-analysis of the relationship between collective victimhood beliefs and conflict-related attitudes. Examining 745 estimates from 103 articles, we assess the relationship between collective victimhood beliefs and hawkishness, reconciliation (attitudes towards current or former adversaries), out-group exclusion (attitudes towards groups with which one is not in direct conflict), and in-group attachment. While we find an aggregate positive association between collective victimhood beliefs and conflict-related attitudes, there is an important distinction between non-inclusive and inclusive forms of collective victimhood: non-inclusive collective victimhood beliefs are associated with greater conflict-related attitudes, whereas inclusive collective victimhood beliefs generally have opposing effects. These results are consistent across a wide range of geographic contexts, types of conflict experiences, and identities. They also extend to the association between collective victimhood beliefs and the emotions and cognitive perspectives that are often identified as mediators. Methodologically, although observational and experimental studies reach similar conclusions about the direction of the relationships, experimental studies find consistently smaller effect sizes.
