According to this theory, everyone has a "primary deviant", but only those who are labeled as "primary deviant" can embark on a "deviant life". The labeling of a person is closely related to the process in which social members in the surrounding environment define or calibrate him and his behavior. Therefore, an important task of social work is to restore those who were originally thought to have problems to "normal people" through a process of redefinition or calibration.
