This research provides evidence that people overestimate the extent to which their actions and appearance are noted by others, a phenomenon dubbed the spotlight effect. In Studies 1 and 2, participants who were asked to don a T-shirt depicting either a flattering or potentially embarrassing image overestimated the number of observers who would be able to recall what was pictured on the shirt. In Study 3, participants in a group discussion overestimated how prominent their positive and negative utterances were to their fellow discussants. Studies 4 and 5 provide evidence supporting an anchoring-and-adjustment interpretation of the spotlight effect. In particular, people appear to anchor on their own rich phenomenological experience and then adjust insufficiently—to take into account the perspective of others. The discussion focuses on the manifestations and implications of the spotlight effect across a host of everyday social phenomena.
