We assume that a voter’s judgment about a proposal depends on (i) the proposal’s probability of being right (or good or just) and (ii) the voter’s probability of making a correct judgment about its rightness (or wrongness). Initially, the state of a proposal (right or wrong), and the correctness of a voter’s judgment about it, are assumed to be independent. If the average probability that voters are correct in their judgments is greater than ½, then the proposal with the greatest probability of…

A Re-Interpretation of the Normative Foundations of Majority Rule

There are four standard normative defenses for majority rule on two alternatives: fairness (i.e., May's theorem), epistemic (i.e., Condorcet's jury theorem), utilitarian (i.e., Rae-Taylor theorem),
