Quote:Several coworkers of said relative have failed and re-taken - sometimes 2 or 3 times - and then passed. So I really don't know what to make of this whole thing - if you fail and have to retake and then pass, where is the validity in that???
Good question. Short answer is that the polygraph is not scientifically valid. It actually an interrogation DISGUISED as a scientific test.
Once a person totally understands that, a lot of things start to "make sense". Why the examiner seemed to "twist my answers", or "kept asking the same question over and over", or "seemed to be trying to make me unsure of my answer"...etc. These are all interrogation techniques. Not a problem. If you are applying for "sensitive" job, they have an obligation to interrogate you. Just realize that THIS is what they are doing. They are INTERROGATING you not TESTING you.
Just don't play their game. Stick to your answers. Don't be talkative. Don't speculate on why your blood pressure, breathing or other autonomic function fluctuated when asked a certain question. Just answer that question truthfully and stick to it.
Try not to answer open ended questions, like "tell me about your trip to Mexico"...etc. Ask them to be more specific. Say "what do you mean?", or "what would you like to know about my trip to mexico?"
At the NSA and CIA, really good applicants, and employees (taking a periodic "update" poly) are sometimes tested and tested and tested until they pass. It's a game! Long time employees who are used to it, know to just "hang in there" and just don't "give'm any rope". They just sit through it and think about baseball, their upcoming vacation trip, what a joke the whole thing is...etc.
In my case (NSA), the hiring committee and security (poly folks) got into a "pissing contest" over my hiring. I don't blame the poly folks, as I got so pissed I ripped off the straps and used some, uh, colorful nautical terms, to let them know what I thought of their so-called test. I think I even mentioned the false negatives of "Aldrich Ames" and used the word "bogus"(not recommended

) So, I'm pretty sure I made some "enemies" in their office that day.
Anyway, to my surprise, six months later, I got a call from HR offering me a retest! But is was just to make the hiring committee happy. They had no intention of passing me. I had disparaged their profession and offended their god. I had ripped off the "sacred straps" and blasphemed against the "holy box" .

So they were just going through the motions, and trying to dig up some "dirt" they could take gleefully back to the hiring board. So bet it!
I must have really pissed them off, because they reported me to the FBI, who investigated me for poss espionage and found absolutely NOTHING! The SA I talked with was even apologetic about it.
Just remember, don't trust them if they offer you a retest. Don't be belligerent either, just trust them or buy their line that they are there "to help you get through this...."
Study TLBTLD, and thoroughly learn and understand what employment screening polygraphs are all about. Kind of like studying up on car salesman "tricks and tactics" before visiting a car lot.
Good luck,
TC
P.S. I have this FBI SA's report on file obtained through a FOIA request.
