Lie detector

[I give Up]

I devoured the search engine on the forums, but I found no threads dealing with this topic, so sorry if this bizzare question has been asked before.

And, sorry if its way off topic.

I have a chick that I feel may be lying to me. I understand that there are certain phsyiological methods to use to see if someone is telling you a lie, and I was wondering if anyone has any prior experience to using them or on knowedge on how to use them.

For example, someone lying to you might:

Cross their arms or legs
Cover their face
The pupils might get smaller
They may look in certain directions
They will fidget etc.....


Anyone know anything else in regards to the type of tests that cops use to detect deception?

Well they have done many studies on this and most of them come to the same conclusions -

that it is VERY difficult to tell when someone is lying to you. Even people that are trained at it have a very poor success rate.

If I remember correctly the group of people that are actually the best at it is the Secret Service. And even they were only able to spot the liar around 56-59% of the time. I can't remember the exact figure but I'm pretty positive it was lower than 60%. Not much better than a random 50-50 guess.

I really can't remember what the signs are to look for - what I do remember from the study was that some of the signs that you would intuitively think would mean a person was lying were either unrelated or actually very misleading (they may be some of the ones you've listed above).

One of the signs that I'm pretty sure is legit is when you ask a person a question and they look up and to the left (means that they are accessing the right side of the brain which is the creative side) - BUT to be completely honest I'm not 100% sure about that one.

The only other thing that I know that I do if I am going to lie to someone is to be sure to be very detailed in the lie - vague responses often will lead someone to believe that you are lying.

For instance let's say I was out banging some girl yesterday afternoon and my girlfriend asks where I was.

A weak lie would be: "Uhhh, I took my little brother to get ice cream".

A strong lie would be "I took my brother over to that place on Main St to get ice cream. He let it drip all over the carpets in my car and I wound up dropping $20 on a full service car wash to get everything cleaned. Clumsy ass kid."

You get the idea. The only problem with telling detailed lies is that LATER on you might get things confused and cross yourself up.

Lier Beware!

Found this searching the net:

Couldn't find the study itself though.

"In a 1991 study conducted by the American Psychological Association, more than 500 college students, judges, Secret Service agents, psychiatrists and federal polygraphists were tested on their ability to spot a liar. Only the Secret Service agents performed significantly better than 50/50.

However, there are several common ways to tell if someone is lying: Nonverbal cues include little or excessive eye contact, constant swallowing, shrugging, scratching, blank facial expressions and dilated pupils. Verbal signs include an increase in voice level or pitch, an avoidance of contractions (using "did not" rather than "didn't" to convince people they are telling the truth) or using modifiers and qualifiers, such as "not necessarily" or "ordinarily.""

Here's the link:

See if you can find the actual study though.

Not only does it tell you the best ways to cue in on when someone's lying but it tells you the "cues" that are actually irrelevant - which is important to know as well.

It might be better if you posted the situation, what they said and why you think they're lying. Certain things could be spotted by us (blow off lines, etc.) others--maybe not.

Anyway--what's at stake if they're lying to you?

This is something playing in the back of my head for awhile---

Most of immediately assume and without question that lying is bad. In general, it probably is. I won't get into the small, useful "keep the peace" lies most of use or the "honesty is the best policy" morality discussion--we've all been over that repeatedly since the age of 2.

But I wonder if they've ever gone thru and figured out "if this person is lying to me, does this really fvck with me?" I mean--Pook's Get a Life is ringing in my head--but if you're living your life (and chicks aren't the center of it) then whatever lies or games she's pulling won't really affect you. Eventually she (or whoever) will slip up, but you're centered and won't be thrown by it. But if your worth is tied up in the other person, then their lying to you will inordinately affect you.

--that's all stated kinda rough, I haven't thought it thru, but thought I'd toss it out there.

I've posted this recommendation several times:

Neuro linguistic programming. If their eyes go leftand down they're making something up , if thei eyes go right and up they're remembering something.Try it wiht a friend. Ask him to calculare 6x7 and watch where his eyes go.

 

[I give Up]

Hey

the eye directions that you guys indicated seem oppsosite to me. When you guys say right and left, do you mean from the perspective of the liar or the observer?

 

[neosynthetic]

It's from the liars perspective, they are accessing their right/left side of their brain.

 

[drixsa]

yea one of my cousins is in the CIA and he taught me how to administer a lie detector test to a person without machines

awsome sh!t

ive been messin with so many ppl

 

[I give Up]

UM.

Well, thats what I though. It is from the liars perspective. But I had always been told that of they access their right side, they were lying. And if it was their left side, they were telling the truth.

Well there's a huge over-simpification of a complex topic anyway.

And change your damn username, it's way too pessimistic!

Osc.

I can't tell when a person is lying to me as much as I can really, really tell when they're nervous letting me know something, especially if it's a friend. Sometimes this is because they're lying, but there's many other reasons, too.
