"Polarization, Antipathy, and Political Activism"

by Jiabin Wu and Hanzhe Zhang


We present an evolutionary game theory model in which polarization, antipathy, and political activism are simultaneous consequences of the evolution of individuals' ideologies and their attitudes toward other ideologies. We show that the evolutionary process is likely to result in a vicious path with individuals becoming increasingly extreme and polarized on the ideological spectrum and the society ending up with two politically engaged groups sharing no common grounds and strong hatred against each other.
