IQs of rapists were compared to IQs of nonrapist prisoners convicted of violent crimes and nonrapist prisoners convicted of nonviolent crimes. Subjects were 136 male convicted felons in the Kentucky State Penitentiary. Determination of violent vs. nonviolent crimes other than rape was made upon consultation with a Kentucky Commonwealth Attorney. The results revealed significantly lower IQs for rapists compared to nonrapists convicted of violent crimes and compared to heterogeneous nonrapist convicts. The present research supports the findings of Karacan and co-workers, indicating a general tendency for rapists to have lower IQs than other convicted prisoners.
研究人员将强奸犯的智商与因暴力犯罪被定罪的非强奸犯囚犯以及因非暴力犯罪被定罪的非强奸犯囚犯的智商进行了比较。研究对象为肯塔基州立监狱的136名男性重罪罪犯。除强奸罪外，暴力犯罪与非暴力犯罪的判定需咨询肯塔基州联邦检察官。结果显示，与因暴力犯罪被定罪的非强奸犯以及各类非强奸犯罪犯相比，强奸犯的智商显著更低。本研究支持了卡拉灿及其同事的研究结果，表明强奸犯的智商总体上低于其他被定罪的囚犯。
