Which of the following refers to unwritten rules that govern behavior in a society?

The concept of unwritten rules that govern behavior in society is accurately described by informal norms. These norms exist without being formally codified and shape societal expectations and interactions among individuals. They are based on shared understanding and social expectations rather than official laws or regulations.

Informal norms can include behaviors such as greeting someone with a smile, dressing appropriately for certain occasions, or adhering to table manners during a meal. These norms are learned through socialization and contribute significantly to maintaining order and promoting cohesion within communities.

In contrast, formal norms are codified laws or regulations that are explicitly written and enforced by governmental or institutional authorities. Cultural norms refer more broadly to the values, beliefs, and practices of a particular culture, while established norms might suggest a more general concept that could include both formal and informal aspects. Thus, identifying informal norms as the correct answer emphasizes the significance of these unwritten social rules in shaping everyday interactions and societal structure.
