Political polarization (spelled polarisation in British English, African and Caribbean English and New Zealand English) is the divergence of political attitudes away from the center, towards ideological extremes.[1][2][3]
Most discussions of polarization in political science consider polarization in the context of political parties and democratic systems of government. In two-party systems, political polarization usually embodies the tension of its binary political ideologies and partisan identities.[1][2][3][4][5] However, some political scientists assert that contemporary polarization depends less on policy differences on a left and right scale but increasingly on other divisions such as religious against secular, nationalist against globalist, traditional against modern, or rural against urban.[6] Polarization is associated with the process of politicization.[7]
Scholars distinguish between ideological polarization (differences between the policy positions) and affective polarization (an emotional dislike and distrust of political out-groups).[8]
