A placebo phenomenon, though being widely known, is currently not the subject of research of Russian scientists, and common perception of it does not conform to current academic thinking. The paper presents the relevant information concerning the phenomenon. The analysis results lead to a conclusion that a placebo effect goes far beyond traditionally prescribed therapeutic use. The study of this phenomenon contributes to better understanding of the nature of psychical function and is beneficial for professionals of various fields including psychologists and educators. Latest studies make it necessary for new conceptualization of the phenomenon. The paper for the first time puts forward the idea to treat a placebo phenomenon in terms of the theory of functional systems. This offers prospects for psychological research in the direction not being developed in our country.
