Behavior which fulfills these norms is called conformity, and most of the time roles and norms are powerful ways of understanding and predicting what people will do.There are norms defining appropriate behavior for every social group.
We do not expect people to behave randomly but to behave in certain ways in particular situations.
Each social situation entails its own particular set of expectations about the “proper” way to behave. One way in which these expectations become apparent is when we look at the roles that people play in society.
son, daughter, sister, brother, students, worker, friend etc.
Each social role carries expected behaviors called norms.
Social roles are the part people play as members of a social group.
With each social role you adopt, your behavior changes to fit the expectations both you and others have of that role.
In every aspect of society, there are social norms.
Without norms, there would become chaos because we need norms that define behaviors as proper and others as improper.
