Many psychopaths describe the traditional treatment programmes as finishing schools where they hone their skills. Where they find out that there are lots of techniques they had not thought about before.

Language and words for psychopaths are only word deep; there is no emotional colouring behind it. A psychopath can use a word like, ‘I love you’ but it means nothing more to him than if he said, ‘I’ll have a cup of coffee.

For most of us even the imagined threat of criticism functions to control our behavior. We are haunted to some degree by questions about our self-worth. As a consequence, we continually attempt to prove to ourselves and others that we are okay people, credible, trustworthy, and competent.

A psychopath can tell what you're thinking but what they don't do is feel what you feel. These are people without a conscience.

Too many people hold the idea that psychopaths are essentially killers or convicts. The general public hasn't been educated to see beyond the social stereotypes to understand that psychopaths can be entrepreneurs, politicians, CEOs and other successful individuals who may never see the inside of a prison.

Psychopaths view any social exchange as a ‘feeding opportunity,’ a contest or a test of wills in which there can be only one winner. Their motives are to manipulate and take, ruthlessly and without remorse.

Not all psychopaths are in prison - some are in the boardroom.
