How to tell if a guy is lying?

It is in the details.  Guys lie in color.  They give you details you didn't ask for, want or are not part of the conversation.  If you pay attention they will slip up in some manner.  They always do and the truth comes out.  Be patient and you will find out soon enough.

You should ask him directly something you know he will lie about and you have proofs about the lie. I dont think you necessarily should do it in front someone else, but tell the liar next time you catch him lying there you will tell relatives and friends about his behavour and spread all around that he is not reliable.

you can ask. but just because you ask doesn't mean you are going to be told the truth. \n\nsigns of cheating:\nchange in dress habits\nchanges the way he looks\n(^^^although, he could want a new look, those 2 are tricky)\nhe's never around for you and when he is, he's looking at the clock for when he can leave\ntakes calls in another room so you don't hear them\nhe doesn't answer the phone for you when he normally would and when you do talk to him, he doesn't have a straight answer for why he didn't answer\nasks if your cheating on him\n\njust google 'signs of cheating' and a whole bunch of links show up. Read a few and compare it to your situation.\n\nGut feelings are nothing to ignore. If you truly believe he is cheating, maybe you should go with your heart and leave him.

if the person is already lying im sorry to tell you he will never tell the whole truth.Plus even if he does tell you the whole truth how do you know he isnt lying then.I hope you can figure a way out to find out if he is telling the truth

I'd ask him, but it really does seem like he likes you. so I think he's lieing.

He's lying to you so you don't dump him.  A man will say anything as long as he gets what he wants.

WELL~ ppl always say DONT YOU LIE TO ME. but we are now living in a world where lie is everywhere. I think whether you are going to tell the truth or not ,is depending on who you are dealing wiht. What do you tihnk of him. YOU lie coz, you think you are protecting from the bad so he wont get hurt, coz, you think you know better than he does, and you should decide his life? what kinda desicsion he iwll make? or you lie for yourself.\nI dont think lying is a big deal, ONLY IF its good for both of you.\nSo, i said, Lie, that means, you care and love him, When you found that you dont even worry about this lie thing, he/she means nothing to you. To lie is to care :D

this guy may really do like you meaning that he understands you and he is interested in you but from a female to another you cant believe everything he tells u because dudes do lie now days for no reason. horrey_06@yahoo.com

well if he is telling the truth then he has just told a lie because he just told the truth, and if he just lied then not everything  that he says is a lie, which means that sometimes he is telling the truth and what he just said is a lie. so the truth is that he does lie!

I think that guys feel that they have to lie because they dont feel to comfortable about themselves and they want to impress the girl. It's like if their with their friends and they want to make a cool impression without changing the guy stereotype which is to a bunch of women that all men are dogs which is'nt true. Yes some guys are ass holes but I mean a woman can be a bitch. It's like the stereotype for women that their all manipulative which is also not true. Their not all after your money. Hell cant a woman just like you. But.. back to the origional thing why guys lie; guys seem to lie more and more to impress they dont want to let the girl down and sure lying isnt the best way to make a good impression and I'm not even going to try and back that up but hey were not all perfect. If you feel like the guys lying to you confront him, I know it's not always the easy thing to do but you want someone nice and it's not "nice" to lie so their you have it. If he admits to lying the best thing to do is give a second chance. If he does it again you have every right to kick his but right out that door just tell him "Watch your step on the way out of my life." and leave him.

my boyfriend cant look me in the eye when he's lying...but sometimes u just cant tell...depends on wat kinda guy he is. some guys can look u in the eye and lie to ur face and not give u any signs he's lying but most of the time,if he wont look at u or hes picking with his clothes or fidgeting hes lying.

Ask him. Point blank, out of the blue, look him straight in the eye and say: "Are you cheating on me?" His reaction will tell you exactly what is going on.

I agree that asking would not work.  If you try asking here are some clues that he may be lying.  He says "What" when you ask him.  He asks for more details (what do you know) like "When" or "With who", he takes a longer time to respond (he's thinking of a lie), also it has been my experience that people are actually more calm when they lie, think about it if someone asks you if you did something wrong that you didn't do you'd be like "No Way!" and you'd get more agitated if they persisted.  But if you did do this bad thing you'd be kinda calm/monotone/Homer Simpson-like "No, I didn't do that" and you'd get more nervous if they persisted.  I would try spying on him first and see what you can dig up before you go asking questions that make you look distrustful.

It depends on how well you know the person.  If you suspect someone is lying just ask round about questions on the subject in question and see how different the answers are.  Works like a charm.

just ask him directly and look into his eyes...actually if you really feel love for this person, you will right away see it thru his eyes if he's lying...

No there is not.\nIn all of my years of lying and being lied to in various walks of life I've learned that everybody lies, everybody gives it away, and detecting a lie is more detective work than "dead give-away".\nYes there are lots of bodily quirks to pick up on when someone lies. These (like the eyes for example) reflexes really do not indicate a person is lying. They rather indicate that a person is nervous. Very often that is because they are lying but sometimes it is for any one of many other reasons. For example a murderer might pass a lie detector and even fool seasoned detectives, but you might fidget and cry and do all sorts of strange things if the cops stop at your door and ask where you were yesterday even if you were home quietly minding your own business.\nThe truth is to get to the bottom of a lie you have to be aware of what a particular person does when they lie. To do this you must be calculated and patient. \n1.)Wait to be told a lie that you know is a lie and begin to note any significant or slightly unusual behaviours (such as body language and voice tone out of the ordinary).\n2.) Engage the liar in a conversation where you request as much detail about the lie as you can. Make careful note of body language etc., and note the details of the conversation. Sound interested and convinced and you should get enough info for later.\n3.) Be patient. Find more proof.\n4.) You have to wait until the "LIE" surfaces a second time. You can elicit this it can be in the same conversation.\n5.) Make sure you heard right, ask them to repeat the lie. Make note of all body language etc.\n6.) Make a note of time date or other significant information at the time so you can remember enough to be certain for yourself that you know they have been caught.\n7.) Now this is where this all pays off. You sit your liar down and YOU initiate the conversation about any suspected lie. This time you start talking like your convinced and get them to repeat the suspected lie yet again. Watch the body laguage the whole time. You do not ever have to confront them.\n\nPLEASE NOTE:\nThis is a little trick meant to find out what a PARTICULAR PERSON does when they lie. It is meant to help determine the DIFFERENCE BETWEEN nervousness due to lying and other nervous behaviour one might exhibit when they are not lying. It is not meant to find out a lie. The liar always gives it away you just have to figure it out for your own liar.\n\nYou need a lie you know is a lie and they must think you believe it. The more you talk about the lie you know the more you have to watch and see. The more lies you do it with the more accurate you will become. This is something you can do dozens of times with a coworker or nieghbor before you confront them. The more often you do it before confrontation (if you choose confrontation) the more likely  you will be accurate. \nIf you make all of this happen (which could be done with someone you know but probably not a single encounter with a stranger) you should have a solid list of reflexes, behaviours, etc, that you can apply to ONLY THAT PERSON\nYou should be able to have no more than 95% odds that you can detect A person lying. If you want to keep your friends and family don't do this to them.\nYou will be surprised (and not too happy) to know who is really lying to you and about what. But I hope this helps and hope the lie is not too big. \nREMEMBER THE HUMAN MIND IS INCREDIBLE AND NOTHING IS FOOL PROOF.
