In this paper we analyse elections when voters underestimate the correlation between their information sources (“correlation neglect”). We find that this cognitive bias can improve political outcomes. We show that the extreme beliefs which result from correlation neglect induce some voters to base their vote on information rather than on political preferences. We characterise conditions on the distribution of preferences under which this induces higher vote shares for the optimal policies and better information aggregation.
