Level of confidence in their prediction also contributed to anticipated election outcomes. A minority of respondents who displayed accurate information about the outcome of the previous election showed no WT effect in their predictions.

Independent of preference and WT, predictions of nationwide election outcomes also varied as a function of electorate of residence. Mechanisms contributing to WT, adaptive and maladaptive aspects of WT, and the human capacity for rational control are discussed.
