This page discusses my creation of "The Psychopath Test" which I put on line in June 2012. It is not a replacement to any professional test of psychopathy as it is not a clinical assessment; it is just for fun.
The test is based upon the Hare Pscyhopathy Checklist (PCL), a professional instrument developed by Dr. Robert D. Hare through his study of prison convicts. He found that certain groups of individuals were much more likely to reoffend than others.
The criteria of the PCL could already be found many places on line when I began working on this project (see Wikipedia for the full list), however the problem is that the PCL items are very broad and require expert judgement to asses correctly.
My version of this test improves on this by asking more specific and narrower questions.
