The Problem of Polarization

Abstract

This chapter completes the diagnostic argument by showing how the political saturation of social space contributes to our vulnerability to belief polarization. Belief polarization is the phenomenon by which like-minded individuals transform into more extreme versions of themselves in the wake of group interactions. It is argued that as the belief polarization effect can be prompted by mere corroboration of one’s views (rather than by face-to-face group discussion), politically saturated social environments can generate within us extremity shifts simply in the course of everyday activities. The belief polarization phenomenon initiates a broader polarization dynamic that dissolves citizens’ democratic capacities.
