I have done several examinations on people who likely fit the diagnosis of "Psychopath." None have been capable of circumventing the polygraph. However, it is important to keep in mind that the polygraph is a device, and the examiner is a human being. Polygraph is the best method available to assess deception but we never claim to be perfect.

Thanks for the information. I believe also that a Psychopath can "end run" the Polygraph, but not necessarily the Examiner. What is your opinion on this?
