Austen-Smith and Banks (1996) showed that sincere voting is not typically an equilibrium of the Condorcet voting model when the electorate is large. Here, we reverse their finding by adding to the Condorcet model a third type of voter—one that receives no information in favor of either of the alternatives—as well as global uncertainty about the probability that each voter is such a “no evidence type.” The expected number of no evidence type voters can be arbitrary small; nevertheless, if the electorate is large enough, then each of the two standard Condorcet types votes sincerely in every nondegenerate type-symmetric equilibrium.
