People鈥檚 willingness to act often depends on how many others act, but the structure of such interdependence is hard to disentangle with observational data. We introduce an incentivized method to study interdependence, grounded in threshold models. We apply it to a stratified U.S. sample of 5,000+ Asian, Black, Hispanic, and White adults to examine support for affirmative action. We document substantial heterogeneity in thresholds consistent with preregistered hypotheses from a model. Following changes in federal support for affirmative action, thresholds shift even as perceived benefits and beliefs remain unchanged, indicating that thresholds provide insights not captured by standard behavioral measures.
