DIA’s polygraph differs from the polygraph program at the Central Intelligence Agency (CIA) and National Security Agency (NSA). DIA requires its employees complete a Counterintelligence (CI) Polygraph while CIA and NSA require a more invasive Full-Scope Polygraph.
The attached DIA brochure gives an idea of what a polygraph entails. I do not have any experience with DIA’s polygraph program. I have only been polygraphed by NSA and CIA personnel. Both were unpleasant experiences. Polygraph operators are permitted to ask personal questions and accuse their subjects of crimes without evidence. For example, my NSA polygrapher told me one of his subjects was unable to pass his polygraph, the illegal drug question, until he confessed to him his past hard-core (I can’t remember which drug, it wasn’t marijuana) drug habit. He had attempted to conceal his drug habit but once he confessed to his polygrapher, got this off his chest, he passed. The polygraph experience is invasive and humiliating lacking oversight.
