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 less competent people will rate their own ability higher than relatively more competent people. It also explains why actual competence may weaken self-confidence because competent individuals falsely assume that others have an equivalent understanding. "Thus, the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others."[1]

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).[3] They hypothesized that with a typical skill which humans may possess in greater or lesser degree,
Incompetent individuals tend to overestimate their own level of skill.
Incompetent individuals fail to recognize genuine skill in others.
Incompetent individuals fail to recognize the extremity of their inadequacy.
If they can be trained to substantially improve their own skill level, these individuals can recognize and acknowledge their own previous lack of skill.
