Groups amplify the perceived threat and justification for using force against Black people protesting for racial equality—especially among social conservatives

Although most antiracism protests of 2020 were peaceful, at times, there was extreme use of force. Drawing on research that groups amplify intergroup threats, we test whether use of force is perceived as particularly justified against groups of Black people protesting racism. In Study 1, White Americans perceived a group of Black people peacefully protesting racism to be more threatening and more deserving of use of force than the same Black people protesting individually. Notably, when the protest topic did not threaten the racial hierarchy (i.e., environmental protection), Black groups (vs. individuals) no longer amplified perceived threat nor support for force. Studies 2 and 3 demonstrated that this tendency for groups to amplify intergroup threat was stronger among White Americans motivated to maintain the status quo (i.e., social conservatives). We conclude that Black groups protesting racism activate intergroup threats with implications for support for using force against them.
