The Dunning-Kruger Effect shows us that people with few skills or knowledge believe that they have more skills and knowledge than they actually have, and vice versa: those who are more competent tend to be undervalued. For what is this?

"As we learn more than one subject, we quickly discover a world of subtleties of things that still need to be known "

The basic conclusions of this paper summarize that, for a certain skill or area of ​​knowledge, incompetent individuals:

• They are unable to recognize their own incompetence.
• They are unable to recognize the genuine abilities of the rest.
• They are unable to recognize to what extent they are incompetent in the subject.
• If they are trained to improve their skills, they can recognize and accept their lack of prior skills.

Therefore, that person who boasts of their vocal abilities, while irritating our ears, is obeying this phenomenon. Or when experts give measured opinions about the problems, while uninformed people believe they have absolute and fast solutions at the same time.
