IQs of violent sexual offenders (rapists) were compared to those of alleged nonviolent sexual offenders, nonsexual violent offenders, and nonsexual nonviolent offenders. Data were gathered from defendants referred to the medical coauthor for pretrial psychiatric evaluation. Rapists scored lower in the IQ test, but this difference did not appear to be significant in the pairwise X2 comparisons. This held true after controlling for the race of the defendant.
将暴力性犯罪者（强奸犯）的智商与非暴力性犯罪嫌疑人、非性暴力犯罪者以及非性非暴力犯罪者的智商进行了比较。数据收集自被转介给医学合著者进行审前精神病学评估的被告。强奸犯在智商测试中的得分较低，但在两两卡方比较中，这种差异似乎并不显著。在控制了被告的种族之后，情况依然如此。
