A strong and prevalent cognitive bias that causes a large majority of people to rate themselves more highly and more skilled than statistically possible. Lack of self-awareness can cause us to overestimate our knowledge or ability in a given area, and this phenomenon is known as the Dunning-Kruger Effect.
Posited in 1999 by two Cornell psychologists, Professors Dunning and Kruger also found that low-skilled people often have a double bind: they think of themselves as very skilled, but the lack even the basic level of skill that would allow them to detect and learn from their mistakes to get better. It’s very difficult for them to get out of the “trap” of perceiving themselves as superior, thus obviating any need to continue effort at improvements.
They also found that individuals of high skill levels also suffer from a sort of “lensing effect” (now dubbed the Dunning-Kruger Effect accordingly) in terms of their own self-assessment, but in the other direction — they are not generally aware of the rarity of their gifts. They assume most other people have the same kinds of knowledge and critical thinking skills that they do. In other words, careful study of our images of ourselves found us all to be living in a bubble of inaccurate self-perception, on both ends.
How to counteract the Dunning-Kruger Effect:
- Ask for feedback from other people, and listen to it honestly.
- Keep learning and gather knowledge and improving your skills.
