New therapies challenge the myth that psychopaths cannot change

Psychopathy remains one of the most challenging personality disorders to treat. While only about 1% of the population displays psychopathic traits, this group is linked to a significant portion of violent crime. Recent research, however, suggests that new therapies could offer hope where older methods failed.

Historically, treatments for psychopathy have faced scepticism due to stigma and the difficulties in forming therapeutic relationships. But studies now indicate that some interventions may help manage behaviours associated with the condition.

Early attempts to treat psychopathy often proved ineffective. One controversial programme, the "Total Encounter Capsule" at Ontario's Oak Ridge Division, ran from 1965 to 1978. Patients, including Mathew Charles Lamb between 1968 and 1973, were subjected to intense sensory deprivation and confrontation techniques. These methods did little to address core psychopathic traits, reinforcing the belief that the disorder was untreatable.

Research from 2019 found that individuals with psychopathic traits show reduced physiological responses when viewing fearful facial expressions. This blunted reaction may explain why they struggle to recognise how their actions harm others. Some studies now propose that psychopaths lack the motivation for empathy rather than the ability itself.

More recent approaches have shown cautious progress. Cognitive behavioural programmes in prisons have led to modest drops in reoffending rates among inmates with and without psychopathy. Dialectical behaviour therapy and mentalisation-based treatment have also helped reduce self-harm and aggression in those with borderline or antisocial personality disorders.

A UK-based initiative called Building Choices is now testing new ways to improve emotion regulation and relationship skills in offenders. While results are still emerging, the programme suggests that structured interventions could make a difference where past efforts failed.

The shift from pessimism to cautious optimism reflects growing evidence that psychopathy may not be as untreatable as once thought. With targeted therapies, some individuals now show improvements in managing aggression and building healthier relationships. The focus remains on reducing harm—both for those with psychopathic traits and the wider community.
