No doubt many people are annoyed by people who think they are smarter than everyone. But is it worth the blame for the know-alls?
In fact, the blame is the Dunning-Kruger effect, writes Rambler. This effect is a metacognitive distortion. A person can be completely confident that he is doing everything correctly and the rest should also follow his advice. Oddly enough, this behavior is common to all people.
A low level of awareness leads to erroneous conclusions. A person with low qualifications cannot make the right decision and evaluate the consequences of a mistake. It seems to him that he already knows everything well.
People who have a high level of qualification, all the time doubt their conclusions. Thanks to their experience, they are able to correctly assess the situation. But before making the right decision, they will think many times how to do better. Unfortunately, highly skilled people mistakenly believe that tasks that are easy for them are also easy for other people.
The hypothesis about this phenomenon was put forward by Justin Kruger and David Dunning in 1999. In order to prove their case, they conducted an experiment with two groups of students. The study showed that students in the first year tend to overestimate their own skills, cannot adequately assess the really high level of skills in others and are unable to realize the depth of their incompetence. The results of the study were published in the Journal of Personality and Social Psychology.
People with low awareness feel more confident than those who are well versed in a particular case.
