Illusion of understanding. What are the reasons for people's misunderstanding?

Human thinking is already arranged in such a way that we process information in a special way. We can omit some details, or distort what we heard, and sometimes generalize something. In some situations, this is useful, but quite often the “missing links” do not give us the full picture, and make us draw the wrong conclusions. It is precisely because of this that the causes of misunderstanding often arise.
