Psychology

★ The evolutionary theory of behavior (2025)

This is the first part of my project, that is supposed to resolve the current theory crisis in psychology and psychiatry, or at least to add some new approaches to the field.

More information.

Pyramid of adaptation (2019)

This is a book about human behavior. The book includes the model of adaptation to the society, a lot of detailed descriptions of different types of behavior and effective methods of influencing people. This model had been tested, changed and improved in various ways through years, and became the basement of the evolutionary theory. Now the pyramid is obsolete. We have a better model. The book will be left here for history.
