several times for *ahem* background investigations for clearances.

Most notable? Polygraph operators usually have little sense of humor for smart-assed answers.

Just sayin...

Guess that's why they were calibrating it. :D

If you're up for a US Gov. security clearance, they're sometimes more interested in the reaction to the question than they are in the answer to the question, depending on the level of clearance.

one guy i knew said he was unphased by the whole affair.
the other one wanted to kill anyone wearing a suit for 4 months

are you allowed to post here what kind of questions were asked, what the atmosphere was like, how silly the interviewer(s) appear b/c they take their job too seriously?

i can't imagine it's a very intimidating or intrusive ordeal, but i have nothing to go on.

oh, & i haven't done anything "interesting" in the past 10 years.

I've had a CVSA ( Computer Voice Stress Analysis)...which is the new form of Lie detector. It runs off your heartbeat and vocal choird stress. Much more accurate. They SUCK!

Like AMS said, it's more for reaction and to me it was more of a truth detector.

They ask a series of reference questions, i.e. Is you name _____, do you lived at______ to establish a sort of baseline.

Then they ask you control questions, i.e. sort of questions you pretty much have to lie at, the its pretty mundane after that.

I got asked a lot of questions on one back in the 80s after the Jerry Whitworth spy scandal in the Navy. Mainly because I had the same last name and held a security clearance.

All in all, pretty boring affair.

However..do NOT make joking references to choking chickens or any activity that would involve Velveeta cheese...

CSVA doesn't work with a damn. It's on par with chance. Poly is only marginally better and it depends on how good the examiner is at his job.

Oh, and as it's been stated, they don't have a sense of humor at all...........

It worked perfectly when I took mine 3 years ago for my pre-employment tests. Nailed everything on the head.

I don't know how CSVA would be worse b/c the CSVA in this thread stated it use heart rate (like a polly) with the addition of voice deflection/tone?

Well, they're now banned by the DOD, no alphabet soup agency will touch it, and all the research is show less than 50% accuracy.

You got lucky it went the right way.

Wow, most local law enforcement agencies around me still use them. Hadn't heard that.

Traditional poly uses HR, breath rate, GSR and BP, and basically they looks for a change in them.

Basically in CSVA HR is a signal to the system to look for the voice strain.

A lot do, doesn't mean they work. DOD had them at Gitmo and found out how bad they were. A rape case in vegas a year or two ago got thrown out because they used it.

Poly can be really inaccurate, but it's everywhere too.

That is because you can learn to beat them.

You can also be too stupid and just fail them (see PSP's post above).
Has nothing to do with beating it. It's a coin flip even when you're not trying to beat it.

According to the main people that push them, you shouldn't be able to beat it, because it's an involuntary reaction.

Of course the people that "push" it will say that it cannot be beaten...

:disgust1:
The theory it's based on says it can't be. So if you can, then it doesn't work in the first place.

They do make nice props to make people nervous though.............

Works mainly off your physiological reactions to the control/baseline questions. Bunch of crap.

Just dont tell the guy giving the test that you dont beleive in the efficacy of the test, that is not admissable in court, or that you know how to beat it. Sure way to get off on the wrong foot.

I think they learn to give the test by mail order...kind of like locksmithing.

Are you sure it was a polygraph.... :twitch:

What he said. There is generally zero tolerance for screwing around. If you try to be evasive or try to answer deceptively, you will fail.

Used to screw with the operators at my HS job at a large retail sporting goods store. Smart ass HS kid giving the frustrated chain smoking old guy a hard time. They dont like "maybe" answers after they have told you 15 times to answer yes or no...
What were they going to do, fire me from a minimum wage geek job?

I've taken one when i got hired with the fire department. They are jacked up. The most random s#it pops into your head at the worst time. A polygraph obviously doesn't work all the time that's why most places that require you to take a polygraph also require you to take a psyche exam and background investigation. Basically if you admit that you smoke pole in your background and fail to mention it in the poly and psyche then there are discrepencies. Based on the magnitude and quantity of descrepencies, then an employer will decide to hire or not hire you.
 
Folks used to review chicken entrails and tea leaves to determine truth.

Now they look at recordings of physiological function.

Neither approach is useful, other than to give the examiners an inflated sense of self-importance and to provide a rationale for the subjective judgement du jour.

Yes the polygraph is a joke. Huge waste of money with no support from the scientific community in a long time.
