False Consensus Beliefs and Populist Attitudes

• In Event: Anti-establishment, Populist, and Conspiratorial Attitudes

Abstract

A well-established finding from social psychology is that people tend to hold “false consensus beliefs”, that is, they regularly overestimate how many others agree with their own opinions. The consequences of such beliefs on how citizens assess democratic legitimacy have been left largely unexplored, however. We reason that false consensus beliefs may give citizens the erroneous impression that their political preferences are shared by most fellow citizens while political elites fail to follow this apparent will of the majority. False consensus beliefs might therefore play a central role in the development of populist attitudes to politics. Using original panel survey data from Germany, we document a robust relationship between false consensus beliefs and populist attitudes. As an indication of broader negative consequences for perceived legitimacy, we also find that individuals who hold false consensus beliefs score lower on external efficacy and political trust. Our findings suggest a novel cause of populist attitudes, rooted in humans’ tendency to project their views onto others - a tendency that may be exacerbated by today’s high-choice media environments.
