Recent increases in public awareness of excessive use of force by police against unarmed minority suspects spurred a number of social justice responses, including racial group protests and the BlackLivesMatter movement. This study examines what social psychological factors predict support for these protests and social justice movements, and if those factors vary by race. Participants completed a survey assessing social attitudes, including social dominance orientation, just world beliefs, modern racism, and awareness of privilege and oppression, and support for protest efforts, including the BlackLivesMatter movement and the AllLivesMatter debate. Results from regression analyses demonstrated that there are racial group differences in 1) overall support for protests, 2) on the predictive social psychological factors, and 3) in the relationships between predicted factors and levels of support. Study suggests that there are unique racial group factors that predict support for group protest, which has implications for promoting inclusive social change efforts. ____
