The book examines the nuances of the reaction of our psyche to a variety of informational influences. The very concept of "information" is considered in detail, which, for all its apparent simplicity, has many very important, but not very well-known features for different situations. And, of course, the issues of the fundamental difference between the processing of information by our brain and the functioning of a computer are not deprived of attention. All the material is presented in a popular form so that it is clear to everyone who is interested in psychology, but does not want to understand professional troubles.
