ABSTRACT In the wake of the 2020 Black Lives Matter (BLM) protests that swept across the nation, this study aims to identify potential cognitive-motivational factors that account for the increased likelihood among pro-movement citizens to engage in BLM activism. Using a nationally representative survey of U.S. adults, we examine a theoretical model grounded in the Orientation-Stimuli-Orientation-Response framework in which the racial empathy that may emerge from perceptions of a hostile information environment plays a pivotal mediating role in the path from partisan support to peaceful/confrontational forms of BLM action. Theoretical and practical implications of our findings are discussed.
