How do a sociopath and a psychopath differ?

Overlapping terms: The two terms are often used synonymously. There is disagreement about the differences between the two terms and there is also difference of opinion regarding how to best measure psychopathy and whether there is a spectrum of psychopathic behavior and symptoms. Essentially, both are conditions where there is poor behavioral control, illegal behavior and a lack of remorse for hurting others.

Nature vs Nurture: Psychopaths are born temperamentally different - impulsive, w/ cortical under-arousal, and lack of fear that leads them to risk-taking behavior and an inability to internalize social rules. Sociopaths are born relatively normal. Their personality disorder is seen to be more an effect of negative sociological factors like parental neglect, bad peers, poverty, iq and other situational factors.

Interchangable: Essentially the terms are interchangeable, with neither really being worse than the other. The full, true clinical term is antisocial personality disorder, the hallmark of which is for the most part, a person who has no conscience.
