The Dunning-Kruger effect is often used to explain why unskilled people overestimate their abilities, but is it really a universal psychological phenomenon or just a statistical artifact? I read a study that suggested the effect might be exaggerated due to regression to the mean, where extreme scores naturally drift toward average. That made me question how often we misattribute everyday overconfidence to this effect. Psychologists still debate whether it's a robust cognitive bias or a measurement issue. What do you think?
