Labelling Theory questions traditional assumptions about crime and criminals. It considers why some behaviors are defined as criminal or deviant in some contexts but not others, why some individuals or groups are more likely to be labelled as deviant, and how responses from social control agencies can affect future actions. Key aspects of Labelling Theory include that deviance is a social construction rather than inherent in acts themselves, and that official labeling and treatment of individuals as deviant can increase further deviant behavior through restricting opportunities and reinforcing deviant identities.
