Hello ATS!
I wanted to philosophize again. And the topic will not be applied, but purely practical. But first, a little theory.
The Dunning-Kruger effect is one of the types of cognitive distortion, in which a person with an insignificant level of knowledge overestimates his
capabilities in a certain area, makes incorrect conclusions, and then, quite naturally, makes erroneous decisions based on them and commits rash
actions. A person who finds himself under the influence of the Dunning-Kruger effect loses the ability to perceive himself critically, cannot soberly
assess the level of his knowledge and competence, while also losing the ability to admit the mistakes he made even to himself.
Over time, this worldview takes on the character of psychological defense: a limited person begins to defend his vision of the situation precisely
because he feels that if he even admits the thought that he is wrong, he will be pushed aside by more talented people.
Talented educated people, on the contrary, understand perfectly well how complex the laws of reality are and how vast the opportunities for gaining
new knowledge are. This leads to an underestimation of their own abilities, to an underestimation of their place in society. "I know that I know
nothing," repeated Socrates, who led a more than modest life and was constantly attacked by fools who were sure of their own rightness.
The effect was theoretically predicted and then experimentally confirmed in 1999 by employees of the Department of Psychology at Cornell University
(USA) David Dunning and Justin Kruger.
The practical source of inspiration was a funny story with a bank robbery. The attention of scientists was attracted by the amazing case of the robber
Wheeler, who robbed two banks one after another, having smeared his face with lemon juice before doing so. The fact is that he sincerely believed that
lemon juice prevents the face from being displayed on surveillance camera recordings. Psychologists were amazed at the depth of incompetence of a
person who did not even try to check the accuracy of his own idea, although the error threatened serious problems.
Dunning and Kruger gathered people in one room, working in different fields, but having very different levels of real knowledge, and asked them to
fill out a questionnaire. Participants were required to indicate the level of competence in the field where they worked. Then they were asked to take
a series of tests that allowed them to establish the true level of their competence. Based on the results, the authors of the study made a graph that
displayed the dependence of real knowledge on people's confidence in their knowledge of their field.
The graph resembled a parabola. In its left part, where the least competent participants in the experiments were presented, it reached its peak - 100%
confidence in their own knowledge. Then it fell sharply - the overwhelming majority of people who were quite knowledgeable in their profession had an
extremely low opinion of their experience and skills. Closer to the end, the curve rose again - here were the best of the best, true experts in their
field. These people could not help but understand that they understood it much better than most other specialists. At the same time, the confidence of
real experts was on average 30% lower than the confidence of incompetent participants.
As Dunning and Kruger found, incompetent people not only overestimated their knowledge, but were also unable to adequately assess specialists who have
a truly high level of qualification in the same field. They sincerely did not believe that they had made mistakes in tests related to their
professional activities. Most remained with their opinion even after they were shown their mistakes and logically substantiated their wrongness.
The theory put forward by Dunning and Kruger is actively studied by scientists all over the world, and one of the subjects of the research is the
causes of this phenomenon. These include:
- Low level of intelligence;
- Improper upbringing (for example, parents often overly extol even minor successes of their child, which kills all the inclinations of the child's
emerging critical thinking);
-Lack of knowledge or very modest practical experience in any field;
-Excessive ambition and self-confidence, painfully inflated self-esteem.
A striking distinctive feature of the Dunning-Kruger effect is the inability of a person who has become its victim to realistically assess his
abilities and capabilities in a particular area. At the same time, an individual subject to this phenomenon is quite sensible, realistic and critical
of himself, as well as his knowledge and skills in other areas.
The Dunning-Kruger effect has a significant impact on all areas of our life, since people are constantly faced with the need to acquire new knowledge,
whether it is the structure of a car or improving their own skills. For this reason, it is worth remembering the described phenomenon both when you
have to evaluate the work of an amateur in a certain area, and when you yourself are immersed in an area little known to you.
On the one hand, you do not need to console yourself with the thought that anyone except you can become a victim of this effect - even the most
competent person in any area should update their own knowledge from time to time. The antidote to this effect will be a critical attitude towards
yourself, and the habit of constantly questioning your own knowledge and skills, while updating and replenishing them.
And now a small practical part. Pay attention to my any thread on ATC. You will immediately see a small group of ATC members, mainly British, who
constantly hate me, consider themselves absolute experts in any topic, any that I publish. And I publish topics on a very wide range of human
knowledge. But they are absolute experts in everything. Moreover, they use exclusively sources from Western media (and we all know the level of their
bias), but I am constantly accused of propaganda.
Well, God be with them. I am not offended, because I am extremely sober and critical about the level of my knowledge and beliefs based on them.
By the way, everything is according to the Dunning-Kruger Effect.))))
Thank you.
