From The Psychopath Test, by Jon Ronson.

In 1975, the top people in the world, who might have something to say about psychopaths, were invited to a ski resort called Les Arcs. The purpose was for the experts to pool their observations on the minutiae of psychopaths’ behavior, the verbal and the nonverbal tics. Were there patterns? Did they involuntarily use giveaway turns of phrase? Their conclusions became the basis for the now famous twenty-point Hare PCL-R Checklist. (Also know as the psychopath test.)
Which was this:
The Psychopathy Checklist is a complex clinical tool for professional use only. Do not attempt to use this on yourself or someone you know. A diagnosis requires explicit training and access to the formal scoring manual. People who are not psychopaths may have some of the symptoms described here. Many people are impulsive or glib, or cold and unfeeling, or antisocial, but this does not mean that they are psychopaths. –Robert Hare, Without Conscience
