Sufficient Grounds for Optimism?: The Relationship Between Perceived Controllability and Optimistic Bias

Abstract

Evidence that perceived controllability is associated with optimistic bias is reviewed. There is sufficient evidence that people are optimistically biased about negative events they perceive to be controllable. More work is needed to establish whether this is also true of positive events. There is evidence also that people often hold beliefs of their personal superiority on control-related dimensions. More experimental studies testing hypotheses about the mechanisms linking perceived control and optimistic bias are required. Future work should also expand the sophistication with which control is treated conceptually and empirically and the range of potential mechanisms examined.
