I have been waiting for a flood of studies applying some of the innovations in behavioral economics and psychology (i.e. Kahneman) to political science. Maybe I have missed it.
There is this, however:
This paper studies the role of overcondence in political behavior. We posit a simple model of overcondence in beliefs. The model predicts that overcondence 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. We test these predictions using novel survey data that allows for the measurement of overconfidence, and find that the predicted relationships are statistically and substantively important.
