Why are psychopaths the product of the environment?
A model of the brain made in the 1930’s imagines a brain as a hill and our mental path as that of a marble rolling down it. We have a fixed path that the marble would follow but if a force were exerted such as a traumatic childhood or brain injury this path would change. The implications of this are that psychopaths are encouraged down the cerebral path by their environment and not as much their preordained track.
Psychopaths are truly a product of their environment. They have brains hardwired for it, but only their circumstances set the proverbial marble rolling. There is a large body of research suggesting that an individual’s upbringing combined with exposure to a negative environment is a leading factor in the development of psychopathic tendencies.
