Labelling theory argues that acts are not inherently criminal, but become defined as deviant when labeled as such by others in society. For labelling theorists like Becker, a deviant is someone who has successfully been given the label of deviant. Moral entrepreneurs play a role in leading campaigns to change laws in ways that create new groups of outsiders and expand the power of social control agencies. Whether someone is arrested and charged depends on factors like their interactions with these agencies and characteristics like class, gender, and ethnicity. Lemert distinguishes between primary deviance, which involves acts that go unnoticed and unlabeled, and secondary deviance, where the label itself leads to further deviant acts and identity.
