We show that a large electorate of ignorant voters can succeed in establishing high levels of electoral accountability. In our model an incumbent politician is confronted with a large number of voters who receive very noisy signals about her performance. We find that the accountability problem can be solved well in the sense that the incumbent exerts effort as if she faced a social planner who receives a perfect signal about her performance. Our results thus shed light on another potential blessing of large electorates in addition to information aggregation as postulated by the jury theorem.

Collective decision procedures should balance the incentives they provide toacquire information and their capacity to aggregate private information. In a decisionproblem in which a project can be accepted or rejected once information about its qualityhas been acquired or not, we compare the performance of a delegation structure with that oftwo voting procedures. Delegation makes one's acceptance decision pivotal by definition.The decisiveness of one's vote in a voting procedure depends on the other agent's vote.This in turn determines the decision to acquire information. In the debate about a rationalchoice foundation of Condorcet's Jury Theorem, the distribution of information was leftexogenous. Mixed (acceptance) strategies were required to validate the Theorem.Endogenizing information acquisition as we do reveals mixed (acceptance) strategies to bedetrimental for welfare as they lead to indifference between buying and not buyinginformation.
