How do you tell when someone is lying?

Answer 1

When they don't keep eye contact while talking.

Answer 2

If not keeping eye contact is a sign of lying, I've never had an honest conversation. You can tell when I'm lying because I can't stop laughing.

Answer 3

Fidgeting

Fidgeting is the most obvious giveaway. Watch for hands and legs that are shaky, rubbing, stiff, self directed, touching the face, nose, chest or behind the ear. Arms crossed over the chest while speaking is the body language for protection and sense of insecurity linked to lying. Other actions include biting the lip, covering the mouth, rubbing the forehead or temple, squinting of the eyes or rubbing of the neck. Women tend to touch their throat’s trachial area.

Over Denial
Repeating protests of innocence.

Lack Of Detail
Liars’ stories often lack detail. Push for particulars. The more specific details that a liar has to provide, the more likely he is to slip up.

Uncooperative
Liars are noticeably less cooperative. They are also more likely to complaint, make more negative statements and appear unfriendly to minimize slip ups.

Eye Contact
Unwillingness to make or never breaking eye contact is often sign of deceit.

Dilated Pupils
Dilated pupils and a rise in vocal pitch are more common in liars than people who told the truth.

Pausing
Forced to make up a story on the spot, most speakers will take a beat or two to collect their thoughts. Lies require a quick mental review of what they have told others to avoid inconsistency and to make up new details as needed.

Inconsistency
Having someone to repeat the story again will enable you to for inconsistencies to ferret out lies.

Consciously Trying Too Hard
Someone who consciously is trying to make you think he’s honest may be lying. For example you may hear the phrase ‘to be honest’ more often than not. Most people assume they will be trusted most of the time. If someone expects otherwise, take a moment to think.

Being Open To Possibilities

Liars succeed in the area where listeners themselves do not really want to know the truth. So be honest with yourself about what it is you want to hear. A boss may want to believe that a trusted employee didn’t have his hand in the cookie jar. However, does the story make sense?

Eye Direction

Their eyes are not fixed upon whom they are speaking to. If the person looks up to the left upper corner of their eye, they are pulling strategy from their right side of the brain, which is the creative side, therefore creating a situation or lying. Looking at the right upper corner of the eye will invoke the left side of the brain which indicates visual recalling.

Stuttering
Stumbling over words without natural fluency.

Change Of Subject

Change the subject quickly. A liar will definitely welcome the change and try to maintain the subject. Their interest are clearly seen. An innocent person will appear confuse and may also try returning to the previous subject.

Level Of Comfort

When someone comfortable with you while answering your questions they will move to their comfort position like tilting their head to one side or the other. When asked a question they might lie about or feel threatened by, they will straighten or stiffen up, no longer tilting their head.

Unusually Longer Response
Q : Are there any drugs or weapons in your car?
A : There shouldn’t be.
Q : Is this your car?
A : Yes.
There are drugs and/or guns/knives in the car. An innocentperson in their own car would answer with an emphatic ‘NO’. Unusually much longer responses or too many details may tip you off to their desperation to get you to believe them.

Filling The Gap
Someone trying to lie may also ‘bridge’ over something they do not want to tell you.

Ah’s Um’s Er’s

People using um, ah, hmm, before answering questions are trying to think of an answer, that more times than not, is going to be a lie.

Over Formal Speech
Use of long words, painfully correct grammar and the full forms of words or phrases that would normally be shortened, suggesting a scripted speech rather than natural conversation.

Very Few Gestures And No Pointing
As physical movement illustrating something being described are a quite common and natural activity.

Justification
Attempting to justify every detail with lengthy explanations.

Conflict In Verbal And Physical Projection
You can find many discrepencies between lie and action. You may also find mismatches between tone of voice and expression. Be sensitive to the person’s emotional expression, specifically the timing and duration, which tends to be off when someone is lying. Emotions can be delayed, remain longer than usual, then stop suddenly. Likewise, they might not match appropriately with verbal statements.

Most Obvious Giveaway
On paper. Seeing what someone said in writing is much more effective at detecting lies than listening to them.

If someone who knows what he is going to be asked will surely have prepared himself. The best liars in the world are the most thorough ones. For example, when Bill Clinton looked at those reporters and told them he never had relations ‘with that woman’ and never blinked or gave ANY indication he was lying, he broke the mold.

Answer 4

Their mouth is open.

Seriously, the more they look me in the eye, the more they are lying

Answer 5

lots of ways...like the avoid eye contact when their telling their lie...or they give too many details in their fabricated story...they get nervous and bite their lip or play with their hair or they cross their arms in front of themselves or put their hands in their pockets. they stutter when they talk or they just look nervous. I deal with liars all the time!

Answer 6

ask them to repeat the story a week later, if they don't tell it the same, they were lying.

also you can ask specific questions about whatever they are talking about.
if they are lying, they will generaly slip up somewhere.

then you can laugh at them, thats the fun part!
*~lol~*

Answer 7

Well, with the people I have been around lately I can tell because they are talking.

Answer 8

Most people will cover their mouth, touch their nose, rub their eye, grab their ear, scratch their neck or pull their collar when they lie.

Answer 9

they will say something that is strange and perhaps laugh a bit. they might look away from you and not make eye contact and they might change the subject

Answer 10

They fidget by shifting every which way, won't look you directly in the eyes, and possibly change in their voice when they speak to you.

Answer 11

when someone is lying they smile and you can see it in their eyes. =] =P
