REACT (ANR-20-CE28-0012) is a research project about reactive practices — the practices in which we engage in the face of wrongness, such as punishment, blame, shame, and forgiveness. The project addresses theoretical, normative and empirical questions about these practices, with a specific focus on the normative distortions associated with discrimination. Its aim is to spell out how reactive practices shape our individual and collective agency.
