Which phrase best describes a social norm?

A social norm is best described as a community expectation because it reflects the unwritten rules and standards that govern behavior within a particular group or society. These norms arise from shared values, beliefs, and practices that members of the community agree upon, which guide their interactions and shape their understanding of appropriate behavior.

Unlike a legal requirement, social norms operate on a social level rather than through formal enforcement, meaning they are upheld by societal pressure rather than legal penalties. While personal preferences refer to individual likes or dislikes, social norms encapsulate collective expectations that can influence behavior on a broader scale. Similarly, a random choice lacks the structure and consistency characteristic of social norms, which are generally predictable and established over time. Therefore, the concept of community expectation captures the essence of social norms effectively.
