How do involuntary interactions with authoritarian institutions shape political engagement? The policy feedback literature suggests that interactions with authoritarian policies undercut political participation. However, research in racial and ethnic politics offers reason to believe that these experiences may increase citizens' engagement. Drawing on group attachment and discrimination research, we argue that mobilization is contingent on individuals' political psychological state. Relative to their counterparts, individuals with a politicized group identity will display higher odds of political engagement when exposed to authoritarian institutions. To evaluate our theory, we draw on the 2016 Collaborative Multiracial Post-Election Study to examine the experiences of Blacks, Latinos, and Asian Americans. For all subgroups and different types of institutions, we find that, for those with a politicized group identity, institutional contact is associated with higher odds of participation. Our research modifies the classic policy feedback framework, which neglects group-based narratives in the calculus of collective action.
