Most people in the intelligence and CI business are well aware of the theoretical and practical failings of the polygraph, but are equally alert to its value in institutional, bureaucratic terms and treasure its use accordingly. This same logic applies to its use in screening potential and current employees, whether of the CIA, NSA, DOE or even of private organizations.
Deciding whether to trust or credit a person is always an uncertain task, and in a variety of situations a bad, lazy or just unlucky decision about a person can result not only in serious problems for the organization and its purposes, but in career-damaging blame for the unfortunate decision-maker. Here, the polygraph is a scientific godsend: the bureaucrat accounting for a bad decision, or sometimes for a missed opportunity (the latter is much less often questioned in a bureaucracy) can point to what is considered an unassailably objective, though occasionally and unavoidably fallible, polygraph judgment. All that was at fault was some practical application of a "scientific" technique, like those frozen O-rings, or the sandstorms between the Gulf and Desert One in 1980.
I've seen these bureaucratically-driven flights from accountability operating for years, much to the cost of our intelligence and counterintelligence effectiveness. The US is, so far as I know, the only nation which places such extensive reliance on the polygraph. (The FBI, to its credit in a self-serving sort of way, also rejects the routine use of the polygraph on its own people.) It has gotten us into a lot of trouble.
On the other hand, there have been episodes in which high-level pressures to use or acquire certain persons entirely override pious belief in the polygraph. One instance which made the press is that of the Iranian connection in the Iran-Contra affair.
I wish you well in this particularly important theater of the struggle against pseudoscience: the national security state has many unfair and cruel weapons in its arsenal, but that of junk science is one which can be fought and perhaps defeated by honest and forthright efforts like yours.
Sincerely,

P.S. I should say that all my outgoing mail goes through the CIA -- unlawfully -- for review, censorship and whatever use it chooses to make of it.
