Intellectual imbalance in either direction, that is, V is greater than P or P is greater than V, proves a useful predictor of the probability of becoming delinquent. For a sample of 513 male juvenile delinquents, P is greater than V proved not to be an artifact of lower overall intelligence quotient (IQ), lower verbal IQ, or socioeconomic status. Once a youth becomes delinquent, the frequency and severity of delinquent involvement can be predicted by the degree of P is greater than V discrepancy with socioeconomic status and race held constant. In sum, the P is greater than V sign emerges as a valuable tool of corrections psychologists. A V is greater than P profile can be regarded a marker predictive of good behavior in the general population and a P is greater than V profile a marker predictive of delinquent behavior in the general population. 1 table and 23 references
