Defining a psychopath

The NY Times reports:

Academic disputes usually flare out in the safety of obscure journals, raising no more than a few tempers, if not voices. But a paper published this week by the American Psychological Association has managed to raise questions of censorship, academic fraud, fair play and criminal sentencing — and all them well before the report ever became public.

The paper is a critique of a rating scale that is widely used in criminal courts to determine whether a person is a psychopath and likely to commit acts of violence. ...

Dr. Hare’s clinical scale, called the Psychopathy Checklist, Revised, is one of the few, if not the only, psychological measures in forensic science with any scientific backing.

In other words, there is only one psychological measure with any credibility in court, and even that one is probably bogus.

There are no reputable psychological measures that are used in the family court. The forensic psychologists in family court are nearly all quacks.
