Abstract: A debate has emerged across disciplines about why people engage in costly helping. Empathy is one mechanism. We highlight a second, more controversial motivator: moral outrage. Integrating findings from moral psychology and intergroup literatures, we suggest outrage is a critical force for collective action and highlight directions for future research.
