Biased Social Comparison in the Moment of Crisis The Better-Than-Average Effect and COVID-19

The better-than-average effect (BTAE) is a mechanism where people perceive oneself as better than others. The BTAE could be one of the phenomena explaining why people follow - in the moment of a global health crisis - guidelines ("I am superior to others, and I [will]) take extra precautions, e.g., a vaccine shot"). In this paper, we investigate the BTAE with 3,066 respondents. In Study 1, in all countries, across two measurements in time, the BTAE was present: Participants rated their involvement in self-protection as greater in comparison to others. Study 2 replicated this effect, proving its robustness. Participants estimated their willingness to vaccinate as higher than others. The BTAE was a significant predictor of willingness to vaccinate.
