I bet you Trump could lie and pass a lie detector test.

[Solomon]

He's had no reason his whole life to ever have to doubt anything he's ever said. He's always made his own reality.

I bet you he believes his own lies so much that he would sail through a lie detector test with flying colors.

Covid is blowing his mind though. He keeps telling it to magically disappear but it won't.

1. Sociopaths can beat the machine because all it does is measure stress.

Sociopaths don't get stressed out by lying so they can lie their asses off without the polygraph showing a single hiccup. This is one reason polygraph tests aren't admissible as trial evidence.

[Mike 03]

3. Yes. This is discussed in John Douglas's books on profiling,

and it's also mentioned in Forensic Psychiatrist Ronald Markman's book Alone with the Devil. And the more time that elapses between the event you want to examine a suspect about and the polygraph examination, the more likely even a non-sociopath is to pass the examination, because they have time to fully justify (in their minds) that their actions were justifiable.

This is interesting stuff.

2. Lying is his native tongue.

4. Presactly

[WyattKansas]

5. I don't think he actually knows what a lie means.

Unless he thinks lying means that you don't ever have a comeback when you are called on it, regardless of how ridiculous it sounds.

6. Back when I worked in IT, I had to take a computer security class...

One of the instructors was a real cop/detective. As part of the class, we all took lie detector tests.

I was able to fool the lie detector, by the simple technique of convincing myself that what I was saying was the truth.

The instructor was... impressed. LOL.

I think I learned that technique when I was a kid and broke or spilled something and didn't want to get caught. Or something.

Maybe I'm presidential material?

[Laelth]

7. I agree.

He believes in his own fantasy world. To him, his lies are the truth.

This is typical of people who suffer from Cluster B personality disorders.

8. Considering the fact that they are utterly worthless . . .

sure.

[RockRaven]

9. I'm not sure Trump has enough epistemology rattling around in his pumpkin head to be able to

explain, even just to himself, the difference between a lie and a truth.

[misanthrope]

10. Costanza

[Midnight Writer]

11. Yes. I had a "friend" who was a sociopath, and he beat lie detectors repeatedly.

He surprised himself.

He had no idea how he beat it, but he bragged about it anyway.

[Disaffected]

12. You don't have to be a sociopath

to pass a lie detector test. There are simple techniques that anyone can apply (and can find on the inter-tubes).

It is also easy BTW to fail when telling the truth - the things are hocus-pocus.
