AI developed with defective code can manifest similar personality characteristics. Recent research may have uncovered a significant biological distinction that differentiates psychopaths. They possess a greater striatal volume in their brains.
Striatal volume pertains to the dimensions of the corpus striatum within the brain. The striatum facilitates the connection between motivation and movement, enabling us to convert thoughts or objectives into actions. It also plays an essential role in decision-making, reward assessment, and social interactions. A study aiming to explore this was conducted by three researchers from Nanyang Technological University in Singapore, the University of Pennsylvania, and California State University, Long Beach. Through brain imaging, they discovered a 9% enlargement in striatal size among individuals with psychopathy.
This investigation was published in the Journal of Psychiatric Research under the title “Larger striatal volume is associated with increased adult psychopathy.” The study additionally revealed that characteristics such as impulsivity and thrill-seeking contributed to the association between psychopathy and increased striatal volume.
