This failure to identify with their future distress seems to be related to their lack of empathy. It's also what makes them likely recidivists. A supposedly reliable method for identifying the psychopath is putting them in an MRI unit and seeing how they react to various kinds of imagery that most of us find distressing. Another method, developed mainly through study of criminals, is the Hare checklist that is the title character in Ronson's book. When I read through the checklist, I couldn't help but think about a certain prominent figure. Here is the list and my untrained and inexpert scoring of the items. Each item is scored as zero one, or two, with zero indicating the subject does not exhibit the trait and two indicating that the trait is exhibited to a high degree.
Item 1: Glibness/superficial charm Score: 2
Item 2: Grandiose sense of self-worth Score: 2
Item 3: Need for stimulation/proneness to boredom. Score: 2
Item 4: Pathological lying Score: 2
Item 5: Conning/manipulative. Score: 2
Item 6: Lack of remorse or guilt. Score: 2
Item 7: Shallow affect. Score: 1?
Item 8: Callous/lack of empathy. Score: 2
Item 9: Parasitic lifestyle. Score 1?

Ronson, Jon. The Psychopath Test: A Journey Through the Madness Industry (pp. 97-98). Penguin Publishing Group. Kindle Edition.Feel free to guess whom I have in mind, or analyze your friends, neighbors and favorite bloggers. I get a score of 29 for the subject that I have in mind. According to the Encyclopedia of Mental Disorders:
A score of 30 or above qualifies a person for a diagnosis of psychopathy. People with no criminal backgrounds normally score around 5. Many non-psychopathic criminal offenders score around 22.
