Antisocial personality disorder, also called psychopathy, is caused by an individual’s brain structure. This paper analyzes the methods, limitations, and findings of the research that supports this claim. Case studies and correlational studies show a connection between gray matter volume in brain regions and psychopathic emotionlessness. Experiments show the inner workings of a psychopath’s brain as they display dishonesty and lack of empathy. Furthermore, this paper will also explain the relevance of this research to the field of psychology, and the practical applications of the research in society as a whole outside, including in the fields of law and medicine.
