Edwin Sutherland developed differential association theory, which states that criminal behavior is learned through social interactions and exposure to criminal and anti-criminal groups. The theory proposes that individuals learn techniques of crime and motives by associating with others who engage in or reject criminal behavior. Sutherland argued that the more one interacts with those who condone criminal acts, the more likely they are to engage in crime themselves. He supported this with a case study of a thief, showing crime is learned through social circles. Sutherland also applied this theory to white-collar crime among respected professionals.
