In the process of socialization, a person masters social roles, and assimilates cultural norms. Why?

It is impossible to learn a social role from books or by the method of a business game, although you can improve yourself in it in this way. Each social role includes many cultural norms, rules and stereotypes of behavior, invisible social threads – rights, duties, relationships – it is connected with other roles. And all this must be mastered. That is why the term “mastering” is more applicable to socialization than “learning”. It is broader in content and includes training as one of its parts.
