Social control mechanisms exist in both formal and informal varieties. The latter type involves unofficial, often subtle, ways in which society encourages adherence to norms and values. These mechanisms include expressions of disapproval or approval that are not codified in law or official policy. A disapproving glance for cutting in line, or a compliment for holding the door open, exemplify this type of social influence. These everyday interactions shape behavior by signaling societal expectations.
The significance of these unofficial controls lies in their pervasiveness and immediate impact on individual actions. They are integral to the maintenance of social order, acting as a constant, often unconscious, regulator of conduct. Historically, these methods of social influence have been primary in smaller, less complex societies. Even in modern, complex societies, they continue to play a crucial role, supplementing legal and institutional controls by reinforcing shared understanding of acceptable and unacceptable behaviors.
