A mob referred to a group of people who did not have the ability to think independently and were easily influenced by group emotions and violence. The Crowd was a book published by the French social psychologist Gustave Le Pen in 1895. It mainly studied group psychology and behavior psychology. Le Pen believed that group psychology and behavior were influenced by many factors, including emotions, beliefs, cultural traditions, political propaganda, and so on.
In Le Pen's view, the characteristics of the mob included: lack of independent thinking and judgment, easy to be affected by group emotions and violence, lack of rational and logical thinking ability, and so on. These characteristics made it easy for the mob to do irrational, violent, and even dangerous behavior, especially in politics and social movements. The performance of the mob was often extreme and unacceptable.
In The Crowd, Le Pen proposed that the study of group psychology and behavior psychology was very important for understanding the evolution of political and social events, and also had certain implications for individual mental health and social behavior.

Over time, scarecrows became a common sight in fields all around the world, and different regions even developed their own unique styles of making scarecrows.
