Ive always wanted to ask this question. Their are military ops people who can pass a polygraph any day of the week. But does anyone know of any obvious signs eg; eyemovement, sweatty palms; pupils dilating, etc...

Decide the truth beforehand (very easy - requires absolutely no previous knowledge). Then assess the validity of their statements on what you already know to be correct.

From personal experience:

People tend to tell you too much information when they're lying. i.e. If someone is refering to a past event and are covering something up or just plain making something up, they will tell you details that they would never have bothered with if they were telling the truth.

People also tend to touch their face more or avoid eye contact more when lying. Eyes (especially) and expresions remain more constant until the point where they reach the "climax" of the lie, at which point they usually look at you expentantly. As if waiting to see if you bought it. More blatantly they will look away then sneak "covert" glances to assess your belief level.

Different people also have diferent habits. Once you're a little used to a persons speach habits, its easier to discern the changes in them that indicate altered though process (i.e. lying, withholding information, hinting, attempting to redirect conversation, etc).

I'm a social animal and I like to watch other peoples interactions as well as watch my own. You can larn a lot by watching how you react in different situations. Its become so easy to determine what people are up to that I dont even say anything. I just play along and watch it unfold. People are very interesting creatures.

and also, lying takes more thought, so new technology has machines you put on your head and detects higher thought levels

If you want to be able to pass a polygraph test, practice lying all the time. It measures things such as increased heart rate, sweaty palms, and the things already mentioned in order to determine if you are lying. The only reason it works is because people get nervous when they lie - especialy when hooked up to a machine they believe to be infallible at detecting whether they are lying or not. So, just know that the machine can't tell what you are thinking if you aren't nervous, and lie with confidence.

That would work quite nicely. Find the target of the interrogation, set their pants on fire, and then conclude they are lying since their pants are in fact on fire. All makes perfect sense. :)

... Its been a long month ...

To pass a polygraph you have to put yourself in a state of mind where you actually believe you aren't lieing. My grandad has an old one and I used to mess around on it.

But there's so much hassle involved in giving someone plastic surgery before you can accuse them of lying... its just so... so messy.

Forget whether he's lying or not, can someone tell me if he's even human? :rolleyes:

I mean really - a nose like that? Then again, I guess we'd have trouble accusing him of lying. :D

Supposedly pupils get larger when people are lying. How you are ever supposed to get close enough to actually observe such a ridiculous thing is beyond me.

if they weigh the same as a duck, they float and thus they're made of wood. you can then see that they would burn just like a witch and therefore they're lying.

First off, the polygraph is a dumb machine. All it can do is report is 'measured response'. That's why they 'baseline', so they can see any physiological response that deviates from the baseline.

The reason most people get nervous when they lie, is because there is a factor of discovery involved-- leading to an _emotion_ called fear. It is emotion which causes the release of chemicals such as adrenaline, causing pupils to dialate, hair to stand up, body to sweat.

This is called the 'fight or flight' response. The body does these things in preparation for heightened awareness, heightened muscle activity/strain, and excessive exertion.

The first thing one must understand is this-- perception is reality. Which means in most cases only you know the 'truth'. They wouldn't be asking if they didn't know it. That truth can be whatever you wish it to be. Whatever you believe it to be. Heck, you _want_ them to find out the truth-- the truth you present.

Believe in your answers, and think about sex. Get an erection, or a buzz, depending on your gender and maintain it. Sex is the number one way to mediate your emotions because it causes a whole-body physiological response that you can control. Do that after you baseline. Adopt a 1000-yard stare, visualize sex to the point of exclusion, and then just answer questions slowly and monotonously. don't flex unless it's your pud, keep fingers and toes lose.

And remember-- polygraphs aren't legally admissible, so there is no risk anyone. No risk, no fear.
