The relationship between IQ and delinquency is complex. Recent studies on the relationship have concluded:

There is an inverse relationship between IQ and delinquency.

Explanation:

Recent studies in criminology have shown that the relationship between IQ and delinquency is an inverse one. People who have a lower IQ are generally more likely to engage in criminal behaviour. However, it is important to remember that this is a general trend, and not an absolute necessity. Moreover, many other factors can play a role in delinquency, including peer pressure and family problems.
