nondeviant
Nondeviant is an adjective used to describe behavior, actions, or individuals that do not depart from established norms or expectations within a given social context. In sociology and related disciplines, deviance refers to violations of norms; nondeviant behavior, by contrast, aligns with those norms and is typically viewed as conforming or ordinary within that setting.
The term is less common in scholarly writing, which more often uses terms such as conformity, normative
Because norms vary across cultures and over time, what counts as nondeviant is contextual and may change.
