polygraph

What do Leandro Aragoncillo, Karl Koecher, Aldrich Ames, Ana Balen Montes, and Gary Ridgeway, the Green River Killer, have in common? Yes, that’s right: they were all, except for Ridgeway, spies who beat the polygraph!

The polygraph is one of the greatest hoaxes perpetrated on the intelligence community since it was sold to the US Government. The problem is that it can easily be beat by anyone trained to do so: spies, and counter-intelligence…and some who don’t need to be trained, such as psychopaths. The reason for this is that it relies on a number of physiological responses to questions: changes in heart-rate, blood pressure, breathing, and even perspiration. As such these don’t really take into consideration the effect of a “test” environment on a subject. Or, if a subject has not been evaluated as to whether they are a psychopath, the subject might actually pass a polygraph test.

As far as those like me who’ve experienced both sides of an interrogation (I was the subject in a Vietnamese political prison, and in other parts of the world, I assisted those in counter-intelligence), the polygraph makes a phenomenal non-intrusive tool of intimidation for an interrogator to be able to observe the subject’s whole scheme of tells, which are impossible to detect in a normal field environment.

But, you know what I also learned from seeing a polygraph being used? Depending on the knowledge and experience of the subject, you could get the same effect out of using a D battery and current tester. It’s all based on what the subject believed and how they would react. If someone believes that a current tester is a lie detection machine, they’ll respond when the current from the concealed D battery draws a reading: they see the pointer move and are told that it’s registering a lie. The real lie detection occurs as the result of how the subject responds, and the interrogator’s interpretation of all the tells, and the information in the subject’s file—I can’t stress enough the importance of how much information can be collected on a prisoner in the field, that a interrogator could use in the room.

That file, that information, can be coordinated with a questioning to tell the difference between lies and truths when observing all that a subject offers: tells and dialogue–information. Examples of tells are, but are not limited to: micro-expressions, subconscious releases of nervous energy through foot, head, hand movements, and overall fidgeting; flushing of the skin; sudden eye movements; dilating of the eyes; touching of self, such as a brushing of the nose, eyes, or ears, baring of the neck; shift in breath rate and intensity, so many, that a trained lie detector needs to be aware of and interpret correctly during questioning of the subject.

This is a lot of information, I know. The key to becoming an efficient lie detector, is getting proper instruction and training, and then applying that information and knowledge in real world scenarios to gather information and discern truth from lie.
