Could a Yeerk fool a lie detector?

[ThinkAgain]

Still, a lie detector is based on heart rate, skin temperature, and other physical factors. If a yeerk could set these to "normal", it could say whatever it wanted and the machine would not be able to detect a discernible difference.

Which is exactly why lie detectors should not be accepted as evidence in court. Who knows what terrible crimes people with alien slugs in their heads could be getting away with?!

I think if parasitic alien slugs are taking over people's minds, I think we have far larger things to worry about that whether or not some guy stole some jewelry.

Agreed

True, but it's the principle of the matter. Aliens could be committing all kinds of criminal activity and lying about it without detection! The fiends!

yes somethig should be done to stop them. mabey a secret organiation. that wear suites..... black suites

[ThinkAgain]

Yeah! Who cares if they're enslaving people, as long as they aren't stealing things!

Okay, as far as I know a polygraph is worthless it can only tell if a person is nervous or giving off physiological responses. So if someone is nervous and they are telling the truth it will detect a false positive and the inverse. Several experiments have been done and all to the same result... they can be easily tricked. So decieving a lie detector for a yeerk who has complete controll over its host is pretty much easy.

I don't even think they would use a lie detector in the first place. They would be smarter then resorting to that.

[Phoenix004]

Depending on how reliable it is, even an untrained person can beat a lie detector if you know how to trick it. I read a book once that mentioned a couple of ways of getting around them.

[ThinkAgain]

Don't count on it. A modern polygraph with a trained person administerring the test, and even a well practiced person will have a run for their money to beat it.

I just think that because a Yeerk can have at least some control over body signs and functions, it should be much easier for them.

The Israelis have a lie detector based on voice that is 98% reliable in detecting lies. This was experimentally verified by myself as a psychology project several years ago. Because the host is liying forcibly, it would be picked up.

[Stasiea]

Everyone can fool a lie detector, it's only American people that really believe that this this really works. No offence.

[Phoenix004]

Anyone with the right training could, but the cops are likely to know who has that training. You are right about America though, as I believe America is the only country where lie detector tests can be used as evidence in court.

[Stasiea]

So why do they need the lie detectors then?

So we can get away with stuff of course. I mean come on, we're a bunch of gray slugs trying to enslave humanity here, we like for you to think that you can successfully use lie detectors that don't require a full brain scan since obviously that would reveal us, ruin the invasion, and totally irritate the Visser and . . . oh, you mean Americans . . . okay uh  . . . so we can't get away with stuff?
