Imagine that a crowd gathered in the square. Everyone is shouting and demanding something. You approach them. Within 10 minutes you are also screaming, you are overwhelmed with a feeling of indignation and protest. It's like you're under someone's hypnosis. You're doing something that wasn't part of your plans half an hour ago. The famous psychologist Gustave Lebon analyzes what influence the crowd has on an individual, how this influence is formed, how you can protect yourself from it, what to do so as not to be drawn into the crowd. This book was widely known throughout the 20th century. French sociologist and scientist Gustave Lebon described technologies for manipulating the masses of people. Crowd power is very strong and can be dangerous. Learn to manage your behavior and do not let yourself be drawn into dubious activities.
