"This study agreed with a recent study in Ohio and in general with the results of the tests in the army in showing that the inmates of penal institutions do not differ in general intelligence from the average of the population. The Army Alpha Test was used in these examinations."

Same study's secondary behavioral finding: prisoners in large numbers exhibited anomalies of behavior or mental attitude, usually not preventing normal social adjustment. No statistics printed.

"It was reported, however, that these prisoners in large numbers exhibited anomalies of behavior or of mental attitude. These anomalies, however, are not usually so serious as to make normal adjustment to society impossible."
