In the documentary, a short amount of time from the testing process was shown for timing purposes, but the interview in fact lasted seven hours. In addition, Chris' results were not only negative, they were shockingly low.
According to reports, he scored a minus 18, when the average score to indicate when a person is lying is around the minus four mark.
