JB would already have been questioned over the years ( 27 psychiatrists in all ) psychoanalysing him in their different fields of psychiatry. I would doubt that anyone could further that,apart from having a scan
This isn't the same as being questioned by a psychologist/psychiatrist. Read the information - it claims to be 100% accurate in tests and real life studies; producing no false/positives and no false negatives. It does however, rely on the accuracy of the individuals memory and only works where there is information that only the killer could know, it also depends on the accuracy of the information held by the authorities etc. If the police believe that a certain thing happened during the crime, but it didn't then clearly, this test would provide a negative result but that doesn't mean the person is innocent (or guilty). It doesn't measure lies or truth, guilt of innocence - just memory.
Dr Lawrence Farwell and his team even offered $100,000.00 to anyone who thought they could beat the test and taught them countermeasures that had previously been effective in non-brain fingerprinting tests. No one has been successful yet.
It's interesting and a BIG step forward from the polygraph IMO.
