The spotlight effect is the psychological phenomenon by which people tend to believe they are being noticed more than they really are. As individuals are often at the center of their own world, an accurate evaluation of how much they are noticed by others is uncommon.

This tendency is especially prominent when an individual does something atypical, such as committing a faux pas.
