Social Identity, Group Life, and Moral Polarization
Social identity, group life, and moral polarization reveal that moral judgment is never wholly private. People reason as members of groups, parties, professions, movements, and publics, and those identities shape who is trusted, what counts as harm, what feels like betrayal, and which norms seem sacred or negotiable. This article examines how group identity reorganizes moral perception, how ingroup favoritism and threat intensify polarization, and how norms, media environments, and institutions can transform ordinary disagreement into hardened moral conflict. Its central claim is that polarization is not simply a matter of different opinions. It is a morally charged restructuring of social reality through identity, loyalty, and antagonistic group life.
