Deviance (sociology) In sociology, deviance describes an action or behavior that violates social norms, including a formally enacted rule (e.g., crime),[1] as well as informal violations of social norms (e.g., rejecting folkways and mores). Although deviance may have a negative connotation, the violation of social norms is not always a negative action; positive deviation exists in some situations. Although a norm is violated, a behavior can still be classified as positive or acceptable.[2]
