Good quote. We actually know next to nothing about how to rehabilitate offenders with high psychopathy scores. Conventional talk therapy, which is still used for most offenders, seems to be counterproductive for them, while a “tough on crime” approach focused on deterrence, strict monitoring and isolation from the surrounding community actually works unusually well. Other incentive-focused approaches—essentially, providing enrichment (education, training etc.) to at-risk subgroups, in order to heavily incent them into lawful activities and deter criminal behavior—also have good potential, but are very expensive.
