The Lie Generator: Inside the Black Mirror World of Polygraph Job Screenings

The continued use of polygraph "tests", as if they have any validity whatsoever, is honestly a scandal.

> Boy, they sure didn't open with a case I could be sympathetic with. Lied to the state police, lied when applying to a city PD, but this time, oh, this time he's telling the truth!

You misunderstood the article. There's no evidence to suggest he lied ever.

Apparently in 3 tries Mythbusters managed to fool the fMRI lie test once. They didn't experiment much with different techniques, I would fully expect success rates to get much worse than that as people get more time to find good techniques for beating the test.

I once was gassing up at a station, and for whatever reason the card reader on the pump wasn't charging, but would let me pump gas anyways. So me, and everyone else who'd used that pump that day, received a phone call from the police telling me to go pay for the gas. I figured it was just an honest mistake and didn't think anything of it.

Fast forward a bit, to where I am undergoing a polygraph examination for the NSA. The exam made me uncomfortable and nervous, but I thought everything was going well. Except for when my interviewer came back and told me I was showing sensitivity towards the hiding crimes question. WTF? And when they do this, they're just giving you enough rope to see if you hang yourself with it. But I had no idea why (or even if) I was showing sensitivity to this question.

They called me in for a 2nd polygraph, this time I didn't show sensitivity to hiding crimes, and I figured I was good to go.

No. I get called into a 3rd exam (each exam was separated by a couple months, mind you). This time the interviewer told me "You did better at the hiding crimes question than I thought you would" W.T.F.?!?! The interviewer then left the room and came back with a manilla folder, from which he procures a piece paper which he reads that I had a suspected larceny charge back at home. I honestly had no idea what he was talking about until I remembered the gas station incident. But after I try telling him about it, he tells me that he doesn't believe me and that he thinks I stole that gas. This leaves me extremely flustered and the rest of the polygraph was a train wreck.

3 strikes and I'm out, my conditional employment with them was terminated.

What irks me the most though, is that when I got back home I retrieved the larceny report from the court house, and in that document the whole story was laid out and my account of the situation was corroborated. So what the hell? Why throw me through such a ringer?

Fuck the polygraph.

I don't support the use of homeopathy, but I don't think that's a great analogy. Polygraphs are used as an interrogation technique, where psychological tricks and deception on the part of law enforcement are "fair game" (we could enter a long discussion as to whether or not deception during interrogations/interviews should be permitted, but regardless, that's the status quo right now).

Trickery and deception when it comes to medicine and personal health are never fair game. I think there's definitely a difference between police telling a suspect "we know you did it" (when they don't actually know) and a doctor telling a patient "take this and you'll feel better" (when the drug actually does nothing).

Also, polygraphs are a little bit more functional than homeopathic medicine: a polygraph can not only induce nervousness, but can also notice it in some cases (even if the nervousness may not be concerned around a particular question and may not necessarily indicate deception and even if there are false positives). This helps create a feedback loop which makes it more powerful than a pure placebo (e.g. a "lie detector machine" you hook someone up to which isn't powered on at all and does literally nothing).
