Authoritarianism and Affective Polarization: A New View on the Origins of Partisan Extremism

Authoritarianism and Affective Polarization: A New View on the Origins of Partisan Extremism. Matthew D. Luttig. Public Opinion Quarterly, August 02, 2017, https://doi.org/10.1093/poq/nfx023

Abstract: What drives affective polarization in American politics? One common argument is that Democrats and Republicans are deeply polarized today because they are psychologically different—motivated by diametrically opposed and clashing worldviews. This paper argues that the same psychological motivation—authoritarianism—is positively related to partisan extremism among both Republicans and Democrats. Across four studies, this paper shows that authoritarianism is associated with strong partisanship and heightened affective polarization among both Republicans and Democrats. Thus, strong Republicans and Democrats are psychologically similar, at least with respect to authoritarianism. As authoritarianism provides an indicator of underlying needs to belong, these findings support a view of mass polarization as nonsubstantive and group-centric, not driven by competing ideological values or clashing psychological worldviews.
