Self-Reported Violent Offending Among Subjects with Genius-Level IQ Scores

Abstract

While research indicates offenders have IQ scores approximately eight points below the population average of 100, very little is known about the crimes of individuals with above-average IQ scores. The current research is not limited to acts of family violence, but it describes the self-reported offending of 465 high-IQ subjects for eight violent crimes: robbery, carrying a concealed weapon, making a serious threat, serious assault, homicide, constructing an explosive device, kidnapping, and attempting suicide. Rates of prevalence and incidence are reported and compared to the rates from a control group of 756 individuals with average IQ scores. High-IQ subjects reported higher rates of prevalence, incidence, and arrest, but lower levels of conviction, than controls. A significant positive correlation exists for offenders between IQ score and lifetime incidence rate for robbery, homicide, and kidnapping, and a significant negative correlation exists between IQ score and incidence of attempted suicide. © 2012 Springer Science+Business Media, LLC.
