Projet
Titre: Citizens as Election Forecasters

Most studies explain the quality of citizens' forecasts by the 'miracle of aggregation,' which states that errors in individuals' judgments tend to cancel out in the aggregate (assuming these errors are randomly distributed). However, for the aggregation principle to work, most citizens must have a better probability of guessing the outcome than they are of making an erroneous prediction. Research on individual-level correlates of forecasting abilities has been somewhat scant. Up until now, explanations of citizens' forecasting skills have taken the form of three models, that is (1) the Political Model, (2) the Contextual Model, and (3) the Contact Model. However, these models, which will be reviewed in the following section, either fail to offer significant explanations of citizens' forecasting abilities or suffer from a cruel lack of testing. Furthermore, alternative explanations have been largely ignored. Although cognitive styles, that is how people think and process information (e.g., how they embrace uncertainty or how they deal with conflicting viewpoints), have been shown to affect individuals' forecasting skills (e.g., Tetlock and Gardner 2015), psychological explanations are almost entirely left out of the voter expectations literature. The lack of adequate research is even deeper for institutional explanations: electoral rules and tradition of coalition agreements have the potential to make election outcomes less foreseeable. Unfortunately, to date, no study has looked at the impact of political institutions on voters' expectations. Citizens appear to be decent election forecasters. However, the reasons for this are still unclear, especially in light of the low political information levels among citizens in democratic countries and individuals' general tendency to overestimate the probability their preferred outcome will occur. Consequently, the proposed thesis is guided by one overarching question: What can explain an individual's ability to correctly forecast the outcome of an election?
