Superiority bias
Illusory superiority effects have been found in a study of health behaviors. The study involved asking participants to estimate how often they, and their peers, carried out healthy and unhealthy behaviors. Participants reported that they carried out healthy behaviors more often than the average peer, and unhealthy behaviors less often, as would be expected given the effect of illusory superiority. These findings were for both past self-report of behaviors and expected future behaviors.
