Labelling theories argue that deviance is not inherent in acts themselves, but rather defined by societal rules and the labelling of those who break them. Certain groups, like the police, benefit from expanding definitions of deviance and enforcing laws in a way that discriminates against the working class. Once labelled as deviant, people are more likely to take on that identity and continue deviant acts due to limited opportunities. While labelling can increase deviance, reintegrative shaming that distinguishes acts from persons may discourage continued deviance and encourage reacceptance.
