Lie detector test

Snowdrop

Has anyone ever taken one of these? A friend of mine is thinking about asking her partner to take one. He has a history of cheating but promises it has not happened for a long time and will never again. She has her doubts but no proof. There are people in the UK who carry them out and they will come here.

I'm guessing this is a polygraph test. Waste of money. The results are totally unreliable.

You can skew the results by just having a thumb tack in your shoe and pressing down on it to produce the elevated physiological reactions whenever you want

Faith

Her: "Honey, I don't trust that you're faithful to me despite your reassurances. I want you to take a lie detector test, m'kay?"

Him: "You're clearly a bit of a psychopath and I'm not taking a lie detector test to "prove" I didn't cheat on you. You're dumped."

Just my interpretation of how the conversation might go. If she doesn't trust him, she shouldn't stay with him. There's no point at which a lie detector test becomes necessary.

Anyway, like monkeyfudge said, they're unreliable.

really if she needs that kinda proof show him the door. if not perhaps couples counselling.

that is one of the most ridiculous things i have ever heard. why is she with him in the first place? there is obviously NO trust what so ever. save herself the money and find a new partner.

what is the country coming to when people are talking about bringing lie detector tests into their relationships. i know, why dont you suggest they go on Jerry Springer or the Jeremy Kyle Show. at least then we can get a good laugh out of it too.

regardless of the trust issue, they are just not reliable

that seems quite extreme. it'd come across bunny boiler style.

Polygraph tests are entirely misrepresented by the media and general public. They measure electro-dermal response. This is basically fluctuations in the voltage of your skin created by your skin ducts filling, and empyting of sweat. Such fluctuations are thought to be induced by change in emotion, amongst other things, but this is as far as it goes. A spike on the graph could be caused by thinking about cheese, blinking, or even muscle twitches. They do not, and can not predict lies.

Ask at the psychology section of the board and they should tell you the same.

Top fact... the guy who invented the polygraph test also invented Wonderwoman... That's why she had that lasso of truth thing...

I've seen this one: it Turn's out Jack's brother aided the terrorists.

the test is unreliable, and she is clearly out of her mind. If she needs to go that far then she needs to dump his ass.

He should beat her more. The cheating wont seem so important then.

Mythbusters tied that method and failed.

They can be beaten by someone well used to lying. They are chiefly effective against people who tell the truth most of the time so people who've spent their lives lying, can beat it pretty easily.
Speaking of which, my dad (a garda) brought home one of the breathalizer machines and i figured out how to beat that too

Banned.

Back on topic please.

I think monkey fudge has been watching "harsh times"

I cant see him agreeing to go. Either he'll be completely offended because he didn't cheat or he'll be worried that the test will reveal the truth if he did. Cant see a scenario where he'd actually go tbh

there is a method that is supposed to work.

every time you are asked a question you are supposed to ask yourself a different question in your head that you already know the answer to. so say if you were asked a question and the real answer was going to be a lie, then you are supposed to ask yourself a different question in your head that has a truthful answer. your body doesnt think it is lying then so the detector wont pick up on it.

i would say you would have to have the mind power and concentration of Derren Brown to pull it off though. becuase you would need to block out the proper questions altogether and just go through the questions in your head.

This isn't about beating lie detectors. Back on topic. :rolleyes:

She should dump him if there's so little trust that she feels the need to put him through a polygraph. He should dump her if she feels the need to make him jump through hoops like that.

Personally, I agree with that. Lack of trust is a massive barrier in any relationship between people.

Lie detector's are very effective for some people, they often see people as telling the truth, when they're not. But very rarely as telling a lie when when they're telling the truth. It may be a good indicator, but they are about as accurate as a drunk man aiming for the toilet. Might get it right, might not.

Instead, the OP's friend should purchase one or two ebooks online, and read into other ways to beat the truth out of people. They can be extremely effective, if done properly. I have a few free ebooks here, which I will pm on request, but the best ones aren't free.
