The Shadow Brain: Unpacking the Biology of Psychopathy Research on psychopathy has revealed a profound difference between individuals with and without psychopathic traits – their brain's reward centers are wired differently.
A study published in the Journal of Psychiatric Research found that people with psychopathic tendencies have a larger striatum, a brain region responsible for motivation, decision making, and response to rewards.
This finding underscores the role of biology in shaping behavior and challenges the assumption that psychopathy is solely a product of environment and upbringing.
