The empirical research consistently indicates an association between intelligence and delinquency. In addition to the empirical discoveries, scholars continue to deliberate the exact processes by which IQ influences delinquent behavior. Furthermore, results from the literature have shown that juveniles of comparatively lower intelligence are more likely to participate in various forms of delinquency than those of higher intelligence. As such, the present study investigated the effect of verbal IQ as well as the control variables of age, gender and race on delinquency. A final sample size of 422, 10-12-year-old youths from the Children of the National Survey of Youth 79 secondary data were used. A logistic regression analysis was employed and predicted that the main independent variable, IQ, and two of the three control variables gender, race were predictive of juvenile delinquency. This study is important because it further extends our knowledge of the biological theory which emphasizes the effect of human biological characteristics on criminality. It should be noted as one of the recommendations for future studies, that there is a continued need for research enabling us to identify better factors predictive of delinquency to develop more effective prevention strategies.
