The Dunning-Kruger effect is a cognitive bias where people with low abilities in a particular domain overestimate their competence in that domain.

Conversely, people with high abilities in that domain tend to underestimate their competence.

This effect was first identified in a 1999 study by psychologists David Dunning and Justin Kruger. In their research, they found that people who scored in the bottom quartile on tests of humor, grammar, and logic were more likely to overestimate their ability than those who scored in the top quartile.

The researchers concluded that this was due to a lack of metacognitive skills, which are the ability to reflect on one's own thinking and learning.

The Dunning-Kruger effect has been observed in a wide range of domains, including psychology, politics, and business.

It can have serious consequences, as people who are overconfident in their abilities may make poor decisions or fail to seek out help when they need it.

Conversely, people who underestimate their abilities may be less likely to take on challenging tasks or pursue new opportunities.

Overall, the Dunning-Kruger effect highlights the importance of accurate self-assessment and the need for people to continually learn and improve their skills in order to avoid the pitfalls of overconfidence or self-doubt.
