Uncertainty and Candidate Personality Traits

Due to the high level of uncertainty in the electorate about candidate issue positions, many scholars believe that voters instead use simpler cues such as personality traits to evaluate candidates. However, information about candidate personality traits is also subject to uncertainty. Using a new direct survey measure of uncertainty included in the 1995 and 1996 National Election Studies, we examine the effect of trait opinions on candidate evaluations and test the effect that uncertainty about those opinions has on the use of traits in an evaluation. We find that uncertainly about a candidate's personality traits reduces both the use of opinions about that candidate's traits in evaluations of that candidate and the overall evaluations of that candidate.
