The Influence of Delinquent Peers: What They Think or What They Do?*

Although the association between delinquent friends and delinquent behavior is well established, the mechanism by which delinquency is socially transmitted remains unclear. Sutherlands theory of differential association holds that delinquency is a consequence of attitudes favorable to the violation of the law, attitudes that are acquired through intimate social interaction with peers. An analysis of data from the National Youth Survey indicates that peer attitudes do affect delinquency. But the effect of peers'attitudes is small in comparison to that of peers behavior, and the effect of peers'behavior remains strong even when peers, attitudes and the adolescent's own attitude are controlled. Moreover, when the behavior and attitudes of peers are inconsistent, the behavior of peers appears to outweigh or override the attitudes of peers. These findings suggest that delinquency is not primarily a consequence of attitudes acquired from peers. Rather, it more likely stems from other social learning mechanisms, such as imitation or vicarious reinforcement, or from group pressures to conform.
