What term describes a shared guideline for appropriate behavior among members of a society?

The term that describes a shared guideline for appropriate behavior among members of a society is social norm. Social norms represent the unwritten rules that govern the behavior of members within a community or society. They influence how individuals are expected to act in various situations, shaping behaviors around issues like respect, communication, and social interactions.

Folkways, while related to social norms, usually refer to more informal norms that dictate everyday behavior without significant moral implications. Social networks pertain to the relationships and connections among individuals rather than norms of behavior. Positive sanctions refer to rewards or affirmations received for conforming to social norms, but they do not describe the norms themselves. Therefore, social norm best captures the essence of the concept related to guidelines for behavior within society.
