About 1.2% of U.S. adult men and 0.3% to 0.7% of U.S. adult women are considered to have clinically significant levels of psychopathic traits. Those numbers rise exponentially in prison, where 15% to 25% of inmates show these characteristics (Burton, B., & Saleh, F. M., Psychiatric Times, Vol. 37, No. 10, 2020).
