The Interplay of Online Network Homogeneity, Populist Attitudes, and Conspiratorial Beliefs: Empirical Evidence From a Survey on German Facebook Users
Abstract Social networking sites are suspected to impede the communication between members of different political camps and thereby increase network homogeneity. This homogeneity can be a result of humans’ tendency to process information in confirmatory ways—a characteristic which is also ascribed to populist citizens and those who hold conspiratorial beliefs. It is hypothesized that populist views and conspiratorial beliefs are associated with higher exposure to like-minded information within Facebook. An online survey with German Facebook users (N = 469) revealed that populist attitudes are positively associated with conspiratorial beliefs but negatively associated with homogeneity. Conspiratorial beliefs are unrelated to homogeneity. Findings are discussed in the light of extant research.
