my title on polygraphplace is WDC III. Because WDC and WDC II got banned,
anyway, in my experience of 4 FBI exams, after they knew I knew the format, the test format changed. I was not notified of the control questions ahead of time and they were not of the "did you ever lie to your mother" variety. They were always periphery issues to the relevants. for example, "have you ever been in the presence of people using drugs" or "are you afraid of failing this test" or "does anyone else know that you have failed an FBI polyrgraph test" and so on.
I think it hurt me that i knew the format, but that is the fault of the stupid assumptions of the test. To me the biggest weakness of the CQT is that it relies on the examiner developing control questions(probable lies) that should make you nervous after a 20 minute interview. I found many of the controls I was asked over my 4 tests laughable. let me elaborate with some of my favorites.
1. (After informing my examiner that i was a programmer)
"Have you ever gained access to prohibited computer files. "
I see, so all IT workers are unethical hackers and MUST have done this at some point. #1 "hacking" is a specific set of skils that most programmers do not posses as there is generally no need to be good at this unless you are a security expert, and that is more often Network admin types, not software developers.
(after saying that I drink socially)"Have you ever abused Alcohol"
ah ha, so everyone who drinks as either been a drunk or drunk driver. Sorry, but I have never done either. Thats a stupid assumption. Why would this be a "probable Lie"
and my favorite...(during my 4th and final exam)
"does anyone else know that you have failed an FBI polyrgraph test"
Hell, yes, hundreds, thousands. you think Im ashamed of failing when im innocent? what reaction is this suppose to cause except exasperation and amusement.
