Social norms are unwritten rules and expectations that dictate acceptable behavior within a society or group. These norms govern how individuals should act, dress, and communicate in various social contexts. They can range from simple etiquettes like saying "please" and "thank you" to more complex expectations related to gender roles, family dynamics, and cultural traditions. Researchers study social norms to understand how they are formed, maintained, and changed. They explore the influence of social norms on behavior, attitudes, and beliefs, as well as the factors that shape and reinforce these norms, such as socialization processes, peer pressure, and group dynamics. Additionally, researchers examine how social norms can either promote or hinder social cohesion, cooperation, and collective action within a community or society. Overall, the study of social norms provides valuable insights into the complexities of human behavior and social interaction, and offers important implications for promoting positive social change and addressing issues like discrimination, conformity, and social justice.
