Evolutionary frame explains political conviction

Publicizing Trivers’s synthesis invites a simple causal story: many hot political and moral disagreements (rigid convictions, moral certainty, family conflict, coalition hostility) are shaped by evolved, gene‑level incentives and kin/coalition psychology rather than just ideology or misinformation. Framing contemporary polarization and moral rhetoric through Triversian mechanisms shifts the terms of public debate — from solely normative or informational remedies to ones that consider evolved incentives and social architecture. — If policymakers and journalists adopt this frame, it reframes solutions for polarization and social policy away from only persuasion and toward institutional designs that change incentives and social ties.
