Dunning-Kruger Effect Pronunciation: /ˈdʌnɪŋ ˈkruːɡər ɪˈfɛkt/ (DUN-ing KROO-gur i-FEKT)
Definition: A cognitive bias in which individuals with low ability, knowledge, or expertise in a particular area overestimate their own competence. Conversely, highly skilled individuals may underestimate their abilities. This effect was first identified by psychologists David Dunning and Justin Kruger in 1999.
Example: Because of the Dunning-Kruger Effect, someone with little experience in car repair might believe they can fix a complex engine problem without professional help.
