The SPOTLIGHT EFFECT is the psychological phenomenon by which people tend to believe they are being noticed more than they really are. Being that one is constantly in the center of one’s own world, an accurate evaluation of how much one is noticed by others is uncommon. The reason for the spotlight effect is the innate tendency to forget that although one is the center of one’s own world, one is not the center of everyone else’s. This tendency is especially prominent when one does something atypical.
