A key contributor to political conflict in the U.S. is the different factual beliefs held by liberals and conservatives. Ditto proposes an account of how such differential beliefs arise that identifies three contributing processes: Moralization (the infusion of issues with moral significance), Factualization (the construction of pseudodescriptive justifications for moral evaluations), and Socialization (the reinforcement of  morallypalatable beliefs by selective exposure to ideologically-sympathetic people, groups, and media sources). Each of these processes are typical of intergroup conflict but have been exacerbated by technological advances and exploited by political actors interested in promoting partisan animosity for political gain.
