As soon as you realize how body language influences a conversation, you will start asking yourself, if it's possible to fake body language.
Basically, you can learn to manipulate main gestures while lying to make your lie appear more like a true statement, but you can't control every single gesture that you make, because there are some expressions - the so-called micro expressions - that you can't control. Those micro expressions are facial expressions that occur in 1/15 to 1/25 of a second, when you try to repress or conceal how you feel. So they occur subconsciously.
People, who know that they will have to lie about a certain topic, will practise their lies in advance. Therefore their lies will appear more convincing and truthful. The reason is that you start believing your own lie, which is why you can tell a deceit without losing your way. Nevertheless you won't be able to plan answers to every single question in advance, which your interlocutor may ask you. While you're lying, your circumstances can also be insurmountable obstacles. One of many things that may happen to you, is for instance that somebody else joins your conversation and ruins your perfectly prepared lie.
Not only can a well prepared lie be ruined through the circumstances in that very moment, but also if emotions are felt at that point in time. The reason is that it's hard to conceal unexpected emotions. The stronger the emotion, the harder is it to control the altering of face expressions, body language signals and voice. But if an emotion starts to develop rather in a subtle, than in a strong way, the individuals, who are feeling this emotion, are barely aware of what they are actually feeling. If they themselves are aware of the change in sentiment, then it's very easy for them to conceal such a delicate emotion. But most of the time the fellow human beings are the ones, who realise that change in emotion through alterations of the behaviour.
Not only is it difficult to disguise certain emotions, but it is also hard to pretend to be feeling a certain emotion, that isn't being felt, because it's important to pay attention to look, sound and act the same way as any other person would, who really is having those sentiments.
"Often the signs of this internal struggle between the felt and the false emotion themselves betray the deceit." (Telling lies paul ekman - 48)
The reason is that the truly felt emotion appears automatically and isn't immediately controllable, when it is felt, whereas the false emotion is something you intentionally want to show. Therefore a mixture between those two emotions arises, which doesn't appear authentic to the interlocutor.
Although lies don't have to be about emotions, they often implicate emotions. For instance, more and more individuals are dyeing their hairs and have their wrinkles injected with Botox as soon as they feel that they are appearing older. When they are asked, how they managed to still look so young and fresh, many people tend to simply answer that they didn't to anything to achieve such an appearance, mainly because they are embarrassed to tell the truth. Therefore those persons not only have to lie about their auxiliary means, but also conceal their abashment. Basically every time somebody is lying, an emotion will be involved, because either the guilt about being untruthful to their conversational partner, the fear of being caught sooner or later or the pleasure in fooling somebody will bring up an additional feeling.
This is the reason why
When you lie while talking to a woman, this woman will more likely have doubts about what you said. In contrary to men, they are not only more able to spot a lie, but they are also better liars, because they tell more complicated lies, whereas men tell simple lies like: "I missed the train"
Immediately before making up a lie, you often look up and to your right, because you are visually picturing something that has never actually happened in reality. While lying, you sometimes start sweating, blush or look down and to the left. You are also inclined to grab your neck. Moreover you are more likely to do a modified version of "the three wise monkeys". You will find an explanation of "the three wise monkeys" in the following chapter ??
At times you shrug one shoulder or tap your fingers, when you lie. Furthermore, you tend to have more eye contact, because you believe that your lie would therefore appear more authentic, which it in fact does.
Allan and Barbara Pease organised series of experiments in which the participants had to tell several lies to others while being interviewed. About 30% of the liars permanently looked away, which was the reason why nearly 80% of the time, those lies were spotted. The rest of those liars did the opposite of what people would expect from somebody who is lying and so they maintained strong eye contact. Therefore the lies weren't as much caught as before: The average of catching the partakers in a lie decreased to 25%. Similarly women were more able to spot a lie, because their more intuitional brain is better in detecting voice changes or any other cue that exposes a liar like the ones that are mentioned in the beginning of this paragraph.
When you have finished telling a lie, you will automatically look at the person you are talking to, to see if that person is far from believing what you just have told or not.
The three wise monkeys
"These monkeys symbolise those who hear no evil, see no evil and speak no evil" aus Buch
If you are about to tell a lie or are already telling one, then you are most likely to use one of those three monkeys as your basis to the body language signal that you are about to use or are already using. As mentioned above, in chapter ??, you will use a minimalist version of those three wise monkeys while lying.
But it should be taken notice that body language is similar to any other language, which means that one word just like one body language signal can have different meanings, whereas the definition of any word is clearer, if it takes part of a whole sentence and a cluster of body language signals specifies the meaning of the appearance.
Therefore, just because you are utilizing a hand-to-face gesture, it doesn't always have to mean that you are lying. It only points out that you are withholding information from your opponent.
The younger you are, the more explicitly you use those hand-to-face gestures. If children, for instance, don't want to hear what their parents are about to tell them to, they just cover their ears. If they see something that scares them off or something that they just don't want to look at, they cover their eyes with either their hands or their arms. And if children lie, they quickly cover their mouth in order to stop themselves from lying. Gestures like that tend to be made quicker and less obvious as you grow up, but they still will appear as soon as you're being dishonest or keeping something from another person or while you are observing deceit.
Sometimes those hand-to-face gestures are used, when you are being doubtful, uncertain or when you are exaggerating.
The most widespread lying gestures
Grabbing your ear
The basis for this gesture is the body language signal that the "hear no evil" monkey does: covering up his ears.
There are a lot of variations for this lying gesture: You either put your hand around or over your ear or tug at your earlobe. Moreover you could manoeuvre your finger backwards and forwards inside your ear and sometimes you even bend your whole ear forward to cover up your ear hole.
Children use less complex, but more obvious gestures to imitate the "hear no evil" monkey. If they are sick and tired of hearing something that their parents or any other people say, they simply put their hands over their ears or put their index finger inside their ears. - siehe -
Rubbing your eye
As mentioned above in chapter ? , you use this gesture when you don't want yourself to be looking at something deceitful, doubtful or unpleasant or when you want to avoid having to look at your interlocutor while lying during a conversation. While children simply cover their eyes, grown-ups tend to make the gesture less obvious by only rubbing their eyes.
Men are more likely to rub their eyes energetically, whereas women tend to make a less vigorous gesture by smoothly touching their skin below their eyes. The use for this subtle gesture is either because a woman has been taught to use more tender gestures or because she only doesn't want to smear her make-up.
Covering your mouth
If you are being untruthful, withholding information from your interlocutor or doubting what your conversational partner is saying, then you will be tent to cover your mouth. This gesture can be used by putting a finger or more in front of your mouth or by even making a fist and sometimes coughing falsely thereto. Especially people, whose parents used to put their index finger in front of their mouth, when their children were ought to say nothing or to quite down.
The three gestures that have been mentioned above - grabbing your ear, rubbing your eye, covering your mouth - still belong to the different variations of "the three wise monkeys".
Other common lying gestures are for example:
Touching your nose
A nose touch can not only consist of a quick nose touch, but also of several fast strokes.
It's important to realise that this gesture is part of a cluster of gestures or else, you can't spot through this gesture a lie, because your interlocutor could randomly have a cold or maybe even hay fever.
In Chicago, there is a "Smell and Taste Treatment and Research Foundation" that has discovered the following:
Not only when you are lying, but also when you are distressed, angry or fearful, chemicals, which are known as catecholamines, are released. Those chemicals let the tissue inside our nose swell up. Scientist found out through cameras, which showed the blood flow, that even the blood flow increases while you are lying, which is why the blood pressure increases. Although the nose doesn't appear any larger, there's still one side effect: Your nose starts to itch, which is the reason why you scratch it a bit.
Moreover it is known through studies with Body Imaging Cameras that even the penis of men distends while they are being dishonest.
The reason why you utilize those different variations of the nose-touch gesticulation is the same reason for using the mouth-cover gesture: You don't only touch your nose when you are being dishonest, but also when you don't want to hear any more of the talking of your conversational partner, because you either don't believe what has been said or if you yourself want to speak.
Scratching your neck
"This gesture is a signal of doubt or uncertainty and is characteristic of the person who says, "I'm not sure I agree".
You are part of a group which is listening to their boss, who is explaining the following project for his company. After the clarification he made, he asks you all if you are able to relate to what he had just said. In order to leave a good impression, you answer: "Yes of course. I can see what you are visualizing.", while scratching with your forefinger the area of the neck underneath the earlobe several times. In the majority of cases five scratches are made, seldom less or even more scratches are used.
Pulling your collar
As with the swelling of the nose tissue while lying, a tingling feeling is caused in the neck tissues while being deceitful. With the intention of satisfying this itching, you stroke or rub your neck. Moreover the blood pressure increases just like it does in the nose (cf. chapter Touching your nose) and therefore you start to sweat on your neck, which is why you pull your collar in order to let some fresh air reach this area.
