Spotlight Effect

The spotlight effect is the tendency to overestimate how much other people notice one's appearance, behavior or mistakes, as though one were standing in a spotlight at the center of everyone else's attention. The effect was named and experimentally studied by the psychologists Thomas Gilovich, Victoria Husted Medvec and Kenneth Savitsky, whose 2000 study found that participants who wore an embarrassing T-shirt into a room of strangers substantially overestimated how many of the other people had actually noticed and remembered it. The researchers attributed the effect to an egocentric bias in which people, being so focused on their own perspective and appearance, fail to adequately adjust for the fact that other people are similarly absorbed in their own concerns rather than watching them closely.
