Dunning-Kruger effect

Dunning-Kruger effect - Wikipedia, the free encyclopedia:

"The Dunning-Kruger effect is an example of cognitive bias in which '...people reach erroneous conclusions and make unfortunate choices but their incompetence robs them of the metacognitive ability to realize it'[1]. They therefore suffer an illusory superiority, rating their own ability as above average. This leads to a perverse result where people with less competence will rate their ability more highly than people with relatively more competence."
