But consider the alternative: the influence of positive affect on overconfidence.

Three studies find evidence that positive affect reduces comparative overconfidence (overplacement). This occurs because positive affect attenuates focalism via decreasing people's tendency to overweight information regarding themselves in the light of information concerning others. Specifically, Study 1 provides evidence that positive affect leads to more realistic estimates of comparative ability and that other-focus partially mediates this effect. Then, Study 2 provides causal evidence that positive affect independently influences other-focus and that other-focus, in turn, influences overplacement. Additionally, Study 2 uses an indirect measure of focalism to better capture this attentional process. Finally, Study 3 explores the influence of negative affect on overplacement. In addition, each study finds that positive affect does not influence overconfidence regarding participant's raw performances (overestimation) as this type of overconfidence is not dependent on self-other comparisons.
