Rise of Populism: Identity Threats as an Explanation in Relation With Deprivation and Cultural Fear

This article introduces the thesis of threatened social identities as a new explanatory approach to the emergence of populist attitudes and tests it explicitly for the first time using quantitative data. We examine whether SIT indicators explain populist attitudes directly and influence effects of indicators of two established approaches: the losers of modernization thesis (LOM) and the cultural backlash thesis (CBT). We use a sample representative for the German labor force. Furthermore, we developed items to quantify the recognition of social identities for the first time with respect to social class and occupational identities. All four of our SIT indicators—recognition of social class, recognition of an East or West German identity, political recognition of occupational groups, and identity insecurity—are significant predictors of populist attitudes. Based on SEMs, we also conclude that these variables are important antecedents of previously established indicators of LOM and CBT on populist attitudes. Overall, we conclude that SIT adds to the literature on the emergence of populism as another complementary explanatory approach. In addition to being effective as an explanation in its own right, this thesis can also fill theoretical and empirical gaps of the established LOM and CBT.
