In a series of six studies, we examined the role that perceived collective continuity (PCC) plays in intergroup attitudes. While the extant literature focuses on attitudes toward ingroups, the current studies chose to expand upon this research by concentrating on three types of outgroups (national, religious, and organizational). Results indicated that for groups perceived as neutral or positive, increased PCC was associated with more positive attitudes, while for enemy groups, increased PCC was associated with more negative attitudes. Entitativity played a mediating role such that as the outgroup was perceived as more continuous, it was also seen as more entitative. Higher entitativity led to less negative attitudes toward a past ally but more negative attitudes toward a past enemy. Results held whether past conflict and PCC were measured or manipulated, further supporting our findings. PCC has negative or positive implications for judgments of outgroups depending on intergroup history. Copyright © 2016 John Wiley & Sons, Ltd.
