This book is an English-language update of the author's popular book on Jung's people types. The field of socionics is fully covered in this book; the author is one of the leading socionists in Russia/Europe. The examples and discussions are written for the everyday reader though specialists will also find them helpful.

This popular book now has a spin-off series, Socionics in Everyday Life, with a small book dedicated to further delineating each personality type in the original book. The spin-off series is being written (two books published, two books in production, 12 more planned) by Kacee Quinelle, friend of Ekaterina Filatova, in memory of "Katya" who died in 2015.
