Abstract
An emerging literature has documented differences in values and behavioral practices (including conformity) between frontiers (areas that were more recently settled) and areas with a longer history of settlement. However, so far there have been few tests of which mechanisms might contribute to the maintenance of such regional differences. The present study provides the first test of the hypothesis that differences in pathogen prevalence might underlie this regional variation. Specifically, the relationship between frontier settlement, pathogen prevalence, and nonconformist voting was explored. Date of statehood, a proxy for recency of settlement, was positively correlated with votes for third-party candidates, and this relationship was partially mediated by pathogen prevalence. Theoretical and practical implications are discussed.
