“…While several other forms of positive illusions have been identified in the psychological literature (e.g., self-serving bias and wishful thinking, Krizan and Windschitl, 2009, Shepperd et al, 2008), we will consider the following three forms: (1) the illusion of control, which is an exaggerated belief in one’s capacity to control independent, external events (e.g., Langer & Roth, 1975); (2) the better than average effect (sometimes also called the superiority illusion), which is the perception of oneself, one’s past behaviour, and one’s lasting features as more positive than is the case (“I am more talented than the average person”) (e.g., Brown, 2012); (3) unrealistic optimism, which is the “tendency for people to believe that they are less likely to experience negative events and more likely to experience positive events than are other people” (Shepperd, Carroll, Grace, & Terry, 2002, p. 65). In our paper, we use the expressions ‘unrealistic optimism’ and ‘optimism bias’ interchangeably, which is common practice in the literature.…”
