Listed below is the Hare Psychopathy Checklist-Revised, a diagnostic tool used to identify psychopathic traits.

It was compiled by Dr. Robert Hare, Emeritus Professor of Psychology at the University of British Columbia, where he has taught and conducted research for more than four decades, devoting most of his academic career to the study of psychopathy.

Dr. Hare created the psychopathy checklist as a tool to determine the length of stay for criminals in prison. It’s obvious that the degree of psychopathic traits present in criminals would play a deciding factor on the length of stay. Dr. Hare ranks each trait on a scale of 0-3. For example, if a prisoner ranks 1 on all 20 traits, then he or she would rank 20. Someone who ranks a 3 on all 20 traits would receive a score of 60 and would probably receive a longer length of stay in prison.

Dr. Hare spends much time with each prisoner and consequently, scores them to his best abilities. But even to Dr. Hare’s own chagrin, he has been duped by many psychopaths. With that in mind, please do not read through the traits and instantly analyze everyone in your life. This information is meant to give you an overview and it’s something you can use as a tool to assess yourself and to use wisely when assessing others.
