This book is a collection of the most interesting articles of my channel in ProProfiling telegrams. The channel is dedicated to non-trivial news from the field of profiling, neurotechnology and lie detection. It brings together a large number of not only professionals in these fields, but also beginners who are looking for quality content. Realizing that many people perceive information read from books better than from a smartphone, for your greater convenience, we decided to release this book in print.
