Overconfidence in Political Behavior and its Effects on Ideological Extremeness and Voter Turnout

From Pietro Ortoleva and Erik Snowberg:

This paper studies, theoretically and empirically, the role of overconfidence in political behavior. Our model of overconfidence in beliefs predicts that overconfidence leads to ideological extremeness, increased voter turnout, and increased strength of partisan identification. Moreover, the model makes many nuanced predictions about the patterns of ideology in society, and over a person’s lifetime. These predictions are tested using unique data that measure the overconfidence, and standard political character- istics, of a nationwide sample of over 3,000 adults. Our numerous predictions find strong support in these data. In particular, we document that overconfidence is a substantively and statistically important predictor of ideological extremeness and voter turnout.
