 Why is it that people who do something in a crowd that they wouldn't do by themselves?

This phenomenon is called Crowd psychology. Crowd psychology refers to the phenomenon of not having information and only following the choices made by a large number of people.Crowds psychology is based on a vague belief that "following the majority benefits me." Regardless of whether it is valid or not, many people follow the majority's actions just because they chose it.

Korea's crowd psychology means a kind of leaning phenomenon or jumping-on-board effect, which means that he/she thinks it will be good because everyone else does it, so he/she follows along. Examples of movies include street cheering in the case of excessive attraction of visitors to certain works, and participation in political and social issues in protest and social movements. In the Internet world, it is also seen as a form of crowd psychology that groups gather to post malicious comments on SNS of certain people who are likely to be robbed or criticized.

This is called social loafing in organizations. Although it is expected that performance will increase as the number of individuals participating in the group increases, the per capita contribution to the performance decreases. This means that they put less effort into working together in a group than when they work alone.
