Not all psychopaths are criminals – some psychopathic traits are actually linked to success
Each man gave a videotaped speech about his personal flaws. Raine and his colleagues found that the men they considered successful psychopaths displayed significantly greater heart rate increases, suggesting an increase in social anxiety. These men also performed better on a task requiring them to modulate their impulses.
The bottom line: having a modicum of social anxiety and impulse control may explain why some psychopathic people manage to stay out of trouble.
