Authoritarianism, socioethnic diversity and political participation across countries

It is argued in this article that threatening stimuli affect political participation levels among non‐authoritarians more than among authoritarians. Focusing on socioethnic diversity, which is known to be particularly threatening to authoritarians and to relate negatively to political participation in the general public, analyses of individual‐ and macro‐level data from 53 countries is presented which supports this thesis. Participation levels among authoritarians are largely static, regardless of a country's level of socioethnic heterogeneity, while non‐authoritarians participate considerably less in countries with relatively high levels of socioethnic heterogeneity. This suggests that authoritarians participate to a proportionately greater degree in the most diverse countries.
