title: Depression, realism, and the overconfidence effect: are the sadder wiser when predicting future actions and events?
abstract: Do depressed individuals make more realistic judgments than their nondepressed peers in real world settings? Depressed and nondepressed Ss in 2 studies were asked to make predictions about future actions and outcomes that might occur in their personal academic and social worlds. Both groups of Ss displayed overconfidence, that is, they overestimated the likelihood that their predictions would prove to be accurate. Of key importance, depressed Ss were less accurate in their predictions, and thus more overconfident, than their nondepressed counterparts. These differences arose because depressed Ss (a) were more likely to predict the occurrence of low base-rate events and (b) were less likely to be correct when they made optimistic predictions (i.e., stated that positive events would occur or that aversive outcomes would not). Discussion focuses on implications of these findings for the depressive realism hypothesis.
