The book examines the nuances of the reaction of our psyche to a variety of information influences. The very concept of “information” is examined in detail, which, despite all its apparent simplicity, has many very important, but not very well-known features for different situations. And, of course, the fundamental difference between the processing of information by our brain and the functioning of a computer has not been neglected. All material is presented in a popular form, so that it is understandable to everyone who is interested in psychology, but does not want to understand professional problems.
