Psychopaths camouflage their predatory nature with what the 20th century psychiatrist Hervey, called a mask of sanity. They tend to be more charismatic, charming, and confident than most people. This social allure is partially a function of the fact that psychopaths experience far less stress, fear, and anxiety than the rest of us. But it is also the result of the psychopath's remarkable capacity to lie about their past,. Their lies mesmerize and sometimes psychologically paralyze their victims.
