Time for the lie detector

[Jane]

It doesn't prove anything from my point of view either BUT unlike you at least I have seen a test take place talk about how the test works and listen to stories of all those who failed such an easy test.

Then obviously, it's you who should think about working with him as you have such confidence in his ability to work a machine.

You should ask Terry for a job you are more of an expert than he is

Also why do you think it's up to you whether people release their test results. That is not up to anyone else to do

As I said if anyone released a guilty result no doubt you would be all over it

Check it out....lots and lots of people fail but for once they do as you see fit and don't release the answer

You seem to change your perspective to suit

Do you work for self proclaimed "polygraph expert" Terry Mullins?

That's Terry Mullins who will only go so far as saying the tests are 90% accurate despite his living depending on people spending hundreds of pounds for meaningless results.

Less partisan commentators put their reliability at no better than 50%. 

It would be great if they worked but they never have.

I'd say that's accurate enough to call it SPOT ON!!!

For Armchair Detective.I had no idea lie detectors were so unreliable.I will do some research and see if this is true.

[lookout]

I think JB was with Mr Mullins for 3 hours during the test and in between times JB would be asked the same question within other questions in no specific order. Anyone lying would get tied in knots if they were human. I'd fail because I'd feel bogged down and not because I was lying. I'm a tad on the impatient side, but so are hundreds of high-functioning psychopaths who don't necessarily kill people.

I'm not lying!

For Armchair Detective,You are correct ,they are definately not 100percent accurate and it states any polyograph tests should be treated with scepticism.

[lookout]

I wouldn't like one. Strewth, my blood pressure rises at the thought of a blood pressure check---even when I do my own at home     I'm hopeless.

Of course, I'm always right. 

Let's put it another way. Let's say you are wrongly accused of a serious crime. The evidence is weak cos you didn't do it but you have no alibi and then you are told you have failed a polygraph and not only that but some genius wants to be able to tell a jury that you failed a "lie detector" - "but they don't always work" you say as you are led off to the prison van..

If you had a calculator that was only 99.9% accurate, you would throw it away because it cannot be relied on.

I think polygraph examinations should be rejected:

According to an American polygraph expert they are easy to cheat if you know how.

A lot depends on how skilled the examiner is, a polygraph is more likely to produce false positives (someone innocent fails) than the other way round.

The fact someone is willing to take it to me alone is quite a statement.

To everyone.Sorry i have wasted your time with this thread ,i truly didnt realise lie detectors were so unreliable.Maybe they will improve the test in future,someone is probably working on it right now,Dare i mention hypnotism or truth drugs,this seems to work in the movies ,isnt there something called sodium penthanol or something like that.I think i heard it mentioned in The guns of Navarone as a truth drug.

Don't apologise it was a interesting thread, polygraphs are generally thought to be around 90% accurate.

Thanks Rob,that makes me feel better.

AWW!!! Please DON'T be sorry. It's been a good thread. It doesn't matter what the outcome has been, it's been debated. I think you are referring to the/a truth drug. They may have become more sophisticated since Guns of Navarone was filmed!!! and it would be good to debate the merits, or otherwise, of hypnotism.
