Political Polarization

Political polarization is the social and political phenomenon in which ideological distance between opposing groups widens progressively, eroding centrist positions and consolidating attitudes toward extreme ends of the political spectrum.

Overview

Researchers distinguish between ideological polarization — divergence in policy preferences — and affective polarization — the growth of hostility and distrust toward outgroups independent of policy disagreement. Affective polarization distorts individual perception of factual information, undermines cross-partisan cooperation, and accelerates the fragmentation of shared public discourse.

Why it matters

Legislative gridlock intensifies and civic trust erodes as moderate positions diminish, and in extreme historical cases unchecked polarization has preceded democratic backsliding and institutional delegitimization. The phenomenon has major implications for governance, journalism, and the design of digital platforms that shape information exposure.
