Modernizing the Measurement of Psychopathy to Reduce Criminal Justice Costs

June 13, 2025 - 14:31

A UC Berkeley psychologist, Keanan Joyner, advocates for a contemporary approach to evaluating psychopathic traits, suggesting that the current checklist, dating back to the 1970s, is outdated. Joyner emphasizes that by refining the criteria used to assess psychopathy, there is potential not only to improve the accuracy of diagnoses but also to significantly lessen the financial burden on the U.S. criminal justice system.

Currently, the economic impact of psychopathy on the system is staggering, estimated at $460 billion annually. This figure encompasses costs related to incarceration, rehabilitation, and recidivism, all of which could be mitigated through more effective identification and treatment of individuals exhibiting psychopathic behaviors.

Joyner’s call for an updated measurement tool reflects a growing recognition of the need for innovation in psychological assessments, aiming to enhance both public safety and the efficiency of legal processes. By adopting a more modern framework, the hope is to facilitate better outcomes for both individuals and society at large.
