The dampening effect of uncertainty on positive and negative emotions

In this article we investigate how uncertainty about outcomes affects feelings with respect to these outcomes. The results of two experimental studies suggest that uncertainty about positive outcomes (Experiment 1) and negative outcomes (Experiment 2) leads to a dampening of emotions that are felt in response to these outcomes. The results are interpreted in terms of the ‘disjunction effect’ (Shafir & Tversky, 1992; Tversky & Shafir, 1992). Copyright © 2006 John Wiley & Sons, Ltd.
