A form of collective social behavior that persists over a long period and gradually finds place as a tradition is called a custom. Examples:

Saying a prayer before each meal--Latin American custom (although it's a custom in other places too, and not every Latin American does this)
it is because various information media do not generally display or analyze all aspects of a subject or event. They may present only part of the story....
