Psychopathy May Be More Treatable Than Previously Believed, Researchers Say
For decades, psychopathy was widely viewed as one of the most difficult mental health conditions to treat. Characterized by shallow emotions, limited empathy, lack of remorse, and a manipulative interpersonal style, psychopathy affects an estimated 1% of the population but is associated with a disproportionate share of serious and violent crime.
Although psychopathy shares some features with antisocial personality disorder and sociopathy, it is considered a distinct condition. Growing evidence now suggests that psychopathy may be more complex than previously believed and that carefully targeted interventions could help some individuals reduce harmful behaviors.
Researchers Are Rethinking How Psychopathy Works
One of the defining features of psychopathy is a reduced emotional response to other people's suffering. Most people show automatic physical reactions when witnessing someone in distress, including changes in heart rate, sweating, or pupil size.
A 2019 study involving violent offenders found that individuals with stronger psychopathic traits displayed much weaker physiological responses. When they viewed photographs of fearful faces, their pupils showed little change, indicating reduced automatic emotional engagement with another person's fear.
Researchers believe these diminished responses may make it more difficult for people with psychopathy to recognize the emotional consequences of their actions. As a result, punishment alone may do little to change behavior, helping explain why many traditional correctional programs have produced limited success.
Prison-Based Treatments Have Produced Mixed Results
Many people with psychopathic traits receive treatment while serving prison sentences or in secure psychiatric hospitals. Cognitive behavioral therapy has produced modest reductions in reoffending among general prison populations, including some individuals with personality disorders.
However, not every program has been effective. The United Kingdom's Core Sexual Offender Treatment Programme, introduced during the early 1990s, was discontinued in 2017 after evidence suggested it failed to reduce reoffending and may even have increased risk for some participants.
Its replacement, Building Choices, takes a different approach by focusing on personal strengths, emotional regulation, healthier relationships, and developing a greater sense of purpose. Although early findings are encouraging, researchers say longer-term studies are still needed to determine its effectiveness.
Earlier treatment programs for psychopathy were often considered ineffective or even harmful. Reports of poor outcomes reinforced the belief that psychopathic traits could not be changed, although researchers now argue that many of those interventions were fundamentally flawed.
One Treatment Program Became a Warning for Mental Health Care
One of the best-known attempts to treat psychopathy took place between the 1960s and late 1970s at the Oak Ridge Division of the Mental Health Centre in Penetanguishene, Canada. Patients participated in a controversial intervention known as the total encounter capsule.
Participants were confined inside a small chamber for sessions lasting up to two weeks while food was delivered through tubes built into the walls. Reports later described forced nudity, involuntary participation, limited professional supervision, and the use of humiliation and coercion.
Mental health experts now consider the program both ethically unacceptable and clinically ineffective. Rather than improving outcomes, such degrading conditions may have worsened psychological difficulties.
These experiences also contributed to the long-standing belief that psychopathy itself could not be treated, instead of highlighting the shortcomings of the treatment methods being used.
Progress in Other Personality Disorders Offers Hope
Researchers point out that similar pessimism once surrounded other personality disorders. Borderline personality disorder, for example, was historically viewed as extremely difficult to treat because of stigma and the challenges involved in maintaining therapeutic relationships.
Over the past several decades, specialized treatments have changed that outlook. Dialectical behavior therapy has been shown to reduce self-harm, psychiatric hospitalizations, and crisis episodes by helping patients develop emotional regulation and interpersonal skills.
Mentalization-based treatment has also produced encouraging results in people with antisocial personality disorder. By strengthening the ability to understand both one's own thoughts and emotions and those of other people, the therapy has been associated with reductions in aggression and impulsive behavior.
These advances have encouraged researchers to investigate whether similarly targeted approaches could help people with psychopathy by focusing on empathy, emotional regulation, and reward processing.
Empathy May Not Be Completely Absent
Scientists have traditionally assumed that people with psychopathy are incapable of empathy. More recent neuroscience studies, however, suggest the picture may be more complex.
A brain imaging study conducted at the University of Groningen in 2013 asked criminal psychopaths to watch videos showing people experiencing pain. Compared with individuals without psychopathy, they showed weaker automatic brain responses linked to empathy.
However, when participants were specifically instructed to imagine what the people in the videos were feeling, their brain activity became much more similar to that of the control group. The findings suggest that the capacity for empathy may still exist but is not activated automatically.
If this interpretation is correct, treatments could potentially focus on encouraging perspective-taking and helping individuals better connect their own behavior with its impact on others.
Early Intervention May Offer the Greatest Opportunity
Some of the strongest evidence for change comes from research involving children and adolescents who display callous-unemotional traits. Although psychopathy is not diagnosed before adulthood, these characteristics can often be identified in children as young as two years old.
Children with elevated callous-unemotional traits typically show limited guilt, reduced concern for others, and shallow emotional responses. They also face a greater risk of developing persistent conduct problems and aggressive behavior later in life.
A clinical trial published in 2018 adapted parenting programs for children between the ages of three and six with these traits. Following treatment, participants showed fewer behavior problems, lower levels of callous-unemotional traits, and reduced aggression.
Parents were encouraged to use warmth, consistency, and positive reinforcement rather than harsh punishment. The approach aimed to make positive social interactions more rewarding while helping children recognize and respond to other people's emotions.
A 2022 study applied similar principles to adolescents by emphasizing personal strengths and positive social roles instead of focusing primarily on punishment. Researchers reported improvements in behavior, empathy, and family relationships.
Researchers Call for a More Nuanced Approach
The growing body of evidence suggests that psychopathy may be more responsive to treatment than previously believed, particularly when intervention begins early. At the same time, experts caution that psychopathy remains one of the most challenging conditions encountered in mental health and criminal justice.
The researchers emphasize that no single treatment is likely to be effective for everyone and that protecting public safety must remain a central consideration. More long-term, high-quality studies are needed to determine which interventions are most successful in reducing serious reoffending among adults with psychopathic traits.
Rather than viewing psychopathy as completely untreatable, many researchers now argue that future efforts should focus on developing evidence-based interventions tailored to the specific mechanisms underlying the condition. Early identification, individualized treatment, and continued research may ultimately offer the greatest opportunity to improve outcomes while reducing future violence and offending.
