Though the terms are used interchangeably, it is currently believed that psychopathy generally comes from genetic factors, such as parts of the brain not developing fully, while sociopathy results from an interruption in personality development by abuse or trauma in childhood. Sociopaths have less consistent behavior than psychopaths. Psychopaths are more controlled and charming. Their manipulation is more detached. They plan ahead. Sociopaths experience anxiety and find rage far harder to control, and they have a harder time assimilating. Inconsistencies between their words and their lives are often easier to detect.
