Can you tell when someone is lying and how?

I have a friend. he is a professional in lying. believe me no one can figure out if he lies or not. but last week he said something that i already know it is a lie and I noticed that he rubber his forehead. so that was the sign. I now know when he is gonna lie he will rub his forehead.

Ah, so your children have 'tells' and you've learned them. That's a good thing. With my daughter, I don't have so much luck. I can kind of tell, but at four years old is more like her little brain is trying to tell people what she thinks they want to hear. Perhaps, telling people what they neeed to near so she doesn't get in trouble. I have a feeling that her answers are strongly determined by the tone of the questions when asked. There are ways that police officers train to figure out if someone is lying. Certain 'tells' (like in poker) like looking up and to the left when thinking of an answer. I don't have much skill at this. I can only look someone in the eye and see how steady their gaze is.

With my daughter she just avoids eye contact when she is fibbing. Sometimes she even makes a fist out of discomfort. And I know right there she is being dishonest. That is actually one of the biggest ways you can tell if anyone is lying! How can they look you in the eye if they are not telling the truth (though some people are very good at it they can find a way).. for the most part, if they don't look at you while they are telling you something.. they are most likely lying.

when people are lying they tend to subconshasly over sell what there saying, so look for more noding than usaual and also a longer emphasis on the word. Plus blinking alot is a sign of nerviousnes

My younger daughter would struggle to lie to save her life and not show her 'tell'. (Which everyone has btw...even the best liars in the universe have a tell of some sort.) Anyway, she can't look at you, and she gives a mumbled response that almost doesn't make sense. Like I said- she couldn't lie to safe her life. My oldest daughter, however is a master at lying...she's had years of practice. To be honest, I don't know what her 'tell' is when she is lying. But recently it became apparent that if she thinks she got away with it she gets very nice and talkative and all sweet. Then you know for sure.

Yes I can tell with my eldest she is 4 and this morning she was saying daddy said she could do something well I knew she was lying lol cos she tryes so hard not to smile and it doesnt work, she is a bad a liar as her daddy. Her dad cant like for anything and I always know cos he will wipe his hand over his face and cant look me in the eye lol I even told him how I know and he still does it like if he tells me they lost their snooker match but they won really I always know he is lying lol!

I can't tell it for everyone but i can definately say when my bf is lying. He has this habit of not looking at me when he is lying. ~pinks~

Dear Vicki, there are many signs which the liars show. But not all who show these signs are liars. You have to be sure about this. VISUAL CLUES: Expression of anger, fear,disgust and embarrassment, shaking of the head, as if to clear it, Touching the face every now and then as if something is showing, Avoiding eye contact ( this is one of the main ones ), shifty eyes, they cannot ever look at you, licking the lips as it gets dry due to mental tension, restless arms and legs, will keep shifting them at all times. Just keep a look out for any of these signs. What you have given an example is not a lie but not the truth either. Your daughter does not want her friend to get hurt. What you have to do is to tell your daughter , that there are ways to tell the truth without hurting or bein blunt. I am also of the type, I cannot hurt intentionally. I'll just tell if it is my friend ' maybe not much, but you have started to put on, it would be better for you to lose a little weight. you might go overboard later on' etc So teach your daughter accordingly. She'll learn that in time.

I think it is quite easy to spot a lie if you are loking for signs. Generally lack of eye contact and a story that doesn't sound quite right is what helps me.
