Abstrakt: In the fields of social choice, public choice and political economics, the main difference between private and political choice is whether individual preferences are aggregated to make a decision. A much less studied difference is whether beliefs are aggregated to make a decision. In this paper, we argue that the need for aggregation creates different incentives for belief updates in private and political choice. We review contemporary theories of biased beliefs in politics: Bayesian misperceptions, behavioral anomalies, and rational irrationality. We examine assumptions and consequences of all the approaches vis-à-vis issues of common knowledge, stability, symmetry, and multiplicity of stable states. As a route for further analysis, we construct an evolutionary model including a coordination failure. Differences in learning dynamics make the political play of this baseline game Pareto-inferior to the private play.
