Parochialism, place-based identity and radical-right voting
What explains the radical right's electoral success? We propose that voters in "parochial" regions are more predisposed to voting for radical-right parties. We define "parochialism'" as a geographic community where voters possess strong place-based social identities characterized by four attributes: low contact with outsiders; strong in-group ties; hostility towards outsiders; and, above all, high dialectal distance from the national standard language. We measure place-based social identity with 725,000 responses to a unique survey of regional German dialects. Using aggregate and individual-level data, we demonstrate that dialectal distance from the national standard language strongly predicts voting for the radical-right AfD party. Our contribution is two-fold. First, we clarify the concept of place-based social identity and its connection to parochialism as a source of radical-right voting. Drawing on recent research in socio-linguistics, we demonstrate that dialects are a useful measure of social identity not previously used to explain political behavior.
