Dunning-Kruger Effect
From 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”. They therefore suffer an illusory superiority, rating their own ability as above average.
The phenomenon was demonstrated in a series of experiments performed by Justin Kruger and David Dunning, both of Cornell University. Kruger and Dunning noted a number of previous studies which tend to suggest that in skills as diverse as reading comprehension, operating a motor vehicle, and playing chess or tennis, “ignorance more frequently begets confidence than does knowledge” (as Charles Darwin put it).
