Over my thirty years in the polygraph business I Have heard many negative remarks about precision and its effectiveness. Plus it always appears the way that it operates and these remarks consistently come from those who have absolutely no direct understanding of polygraph. This comes from judges and senators, representatives and state legislators and a number of other people who've not ever even seen a prueba del poligrafo (Polygraph test) managed, much less analyzed any studies performed by a few of the very reputable institutions of governmental agencies and higher learning in this nation.
The matter which makes this school unique is they have an infinite supply of individuals to discover prueba del poligrafo. Each morning they might bring through ten soldiers to the institution. There were ten students within my class, so we each had a man to run on a test. They might take two or three of the ten soldiers and make a "mock" offense to allow them to have perpetrated. This included things like a robbery, theft, etc. As pupils to run evaluations to them to discover who was guilty, it had been our job. This testing never ceased to amaze me how we pupils "status beginners" that we were, would always come up using the right answer every day. To this day whenever I hear some nay sayer knocking on the truth of polygraph I wish see how incredible this system actually is and only one of these would go.
