Doc Bonn Explains: The Difference Between a Sociopath and a Psychopath"Psychopaths, on the other hand, often have charming and disarming personalities. They are manipulative and can easily gain people’s trust. They learn to mimic emotions, despite their inability to actually feel them, and will appear normal to other unsuspecting people. Psychopaths are often educated and hold steady jobs. Some are so good at manipulation and mimicry that they have families and other long-term relationships without those around them ever suspecting their true nature. An example of such an individual is the serial killer Dennis Rader (“Bind, Torture, Kill”) who had a family, career, civic life and avoided detection for 30 years."

It is likely that psychopathy is the result of “nature” (genetics) while sociopathy is the result of “nurture” (environment). According to the late David Lykken, a behavioral geneticist known for his studies on twins, psychopathy is related to a physiological defect that results in the underdevelopment of the part of the brain responsible for impulse control and emotions. Sociopathy, on the other hand, is more the product of childhood traumas and abuse."
