    If IQ scores in the prison system are not normally distributed, it's certainly plausible that there might be 20% gifted (with at least another peak below the general population mean IQ). I've no idea if this is the case- just sayin'.

    Thank you, Talentdifferent, for sharing the details on this study.

    It seems there was a significant element of self-selection, as eligible inmates elected to take the IQ assessments... or not.

    It is interesting that it was determined this self-selected group was representative of the overall incarcerated population... based on "responses within an expected range". To me, this gives the appearance of a study designed to reinforce a foregone conclusion.

    As this dates back to 1984, and 33 years have passed, possibly it is time for a new study; one that might include several cities.

    Then again, the vast and invasive data collection that we live under may have this information already stored for nearly 100% of the population... including incarcerated persons. It would just be a matter of extracting and reporting.

    Interesting. The book from that article is available on Amazon - Criminal Genius: A Portrait of High-IQ Offenders, by James C. Oleson, September 6, 2016. There is a "Look Inside" feature to allow potential purchasers to sample a few pages of the book.
