In correctional facilities across the American interior, neuroscientists have peered into the architecture of over 800 incarcerated minds and found that psychopathy leaves an unexpected physical signature: not a diminished brain, but an expanded one, with greater cortical surface area concentrated in regions that govern our capacity to feel for one another. Published in Biological Psychiatry: Global Open Science, the work by Radecki, Kiehl, and Cecchetti complicates the long-held assumption that psychopathy is simply a story of neural deficit, suggesting instead a more intricate reorganization

No immediate consumer impact. Long-term potential: improved mental health screening could reduce recidivism costs and inform treatment approaches, potentially lowering incarceration expenses for households via taxes.
Findings may influence criminal justice reform, mental health screening protocols in prisons, and funding for neuroscience research. Could support arguments for early intervention programs and specialized treatment facilities, affecting government budgets and healthcare policy.
