Like other developmental disorders, there is not one single cause of psychopathy, with research indicating a complex interplay of genetic and environmental factors that work together to shape people into psychopaths. These factors could manifest themselves in fundamental biological differences at the neural level between psychopathic and non-psychopathic people — and a new study may have just spotted one such biological difference. …
