Система убеждения. Как влиять на людей с помощью психологии

With so many psychological methods out there, I'm curious how Nick Kolenda selected the most effective ones to include in this book. Was it based on personal experience, research, or a mix of both?

Some of the methods seem powerful but also a bit controversial. I'm wondering if readers have successfully used these techniques ethically in personal or professional settings.

Understanding the timing behind this book's publication might reveal whether current social or political climates influenced its themes or approach.
