Dunning Kruger is more common among ego-centric adolescent neophytes who’ve not yet grown intellectually enough to realize how highly developed human endeavors are. When 9, I thought I was a guitar master for learning 3 chords. But some narcissists & megalomaniacs like Trump never do grow out of it.
The Dunning-Kruger effect is a cognitive bias where individuals with low ability in a specific domain overestimate their skills or knowledge. This phenomenon occurs because they lack the necessary competence to accurately assess their own performance, leading to inflated self-assessments.
