The body doesn't lie.

From the book Communicate by Verberber and Sellnow "Nonverbal communication is inevitable, multichanneled, intentional or unintentional, possibly ambiguous, and the primary means by which we convey our emotions. The sources of nonverbal messages include use of body motions, use of voice, use of space, use of time, and self-presentation cues." Since it is the main way we communicate our emotions, it is perhaps a good way to know if someone is lying

There are indications to notice in a body language which are always telling the truth unless you are a very talented actor/actress. But then the heartbeats can be an indicator for knowing if the person is telling the truth. Gestures tell much, if someone does not look straight into your eyes. Body language and gestures tell many more messages than words. But you need to know that language to know what's the message. I can even now a days interpret from choosen words what's true or not. Words says much about who the person is.

Hi thetis! I am not really an observant person so I can't really tell if a person is lying to me or not. I just can tell that something is fishy through the words they are saying. If they are stammering or if what they are saying does not make any sense. However, I do believe that body language does not lie. Pupil dilation, odd habits, or whatever the body signs that signal lying, have been studied so extensively in the communication field. And they really do tell more than what the mouth says. That is why, those liars who are really good with what they do, really have their minds over their bodies (matter).

yep. you're totally right with that discussion you've started. non-verbal cues are more powerful to believe than verbal cues. like for example when someone is physically hurt and you wanted to know more about the characteristics of the pain, non-verbal cues are more reliable. there are these people that do not really say what they feel. there are times wherein they say it's not painful at all, but as her body language and facial expression shows - you might notice that he's already grimacing and unable to move. and even if you'll touch that certain body part that hurts, a slight touch would aggravate the pain that they feel. so in short, it's better to recognize the non-verbal cues rather than the verbal cues. however, these two should also be combined in order to obtain what the person is trying to let his listener get his point. this situation also the same with out emotional aspect..

Hi, there! Whenever I talk to someone, I usually observe his/her gestures and look at him/her in the eye. In that way, I could tell if someone is telling the truth or the other way around. I must agree with you that the body doesn't lie. It's a good sign to observe when you want to identify if a person is saying the truth or not. :) Nice topic you have here. :) Keep it up..

if the the person touch his nose or ears, he's lying!hahaha

I do believed in body language. We have this saying "action speak louder than words" Me especially trust my instinct most of the time. I can since the person especially i know him/her very much. Just through the actions i can tell that there is something wrong going on. So i trust most on body language.

I also am an observer of body language to see if somebody is telling the truth or not. Some people are sincere and some are not. If someone can look directly to my eyes while speaking then I know he wasnt lying.
