Half a Gift Is Not Half-Hearted: A Giver–Receiver Asymmetry in the Thoughtfulness of Partial Gifts

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.
