About the book: 2020 / Millions of people in the world are subjected to physical and emotional abuse. These are family squabbles or harassment at work, an attack on the street or a school shooting. Even if it seems that the topic of violence does not concern you, it does not. Criminologists say: only 1% of criminals end up behind bars. How to understand whether you should trust a person from your environment? Is he not an abuser and a domestic tyrant? Joe Navarro, an FBI profiler, wrote this book to help ordinary people protect themselves from toxic influences. He divided dangerous individuals into four psychotypes, explained the motives for their actions and gave clear descriptions of how to identify such people and confront them.
