Chapter 17 Observing the Liar's Body Movements
The FBI pointed out from years of interrogation experience: perfunctory language and fake expressions can conceal the true inner thoughts, but body language can reveal secrets.Facing the FBI, a master at reading body language, there are no secrets to anyone's body language.

A person's fingers, hands, arms, legs, and the movement of them, reveal the true emotions of the person.Most of us don't realize that our bodies can speak; when we try to deceive others with words, the truth is revealed quietly.Here, the FBI will decipher a liar's body language for readers.

§§§ Section [-] The pupils of liars will dilate

Psychologists in the West once did such an experiment: let 10 people fast for four or five hours to keep them hungry; let another 10 people just eat food.At the same time, put all kinds of delicacies in front of them, and observe the changes in their eyes.The experimental results found that the pupils of the former were 2.5 times larger than those of the latter.

Because the pupil is involuntarily controlled by the nervous system, the pupil will involuntarily betray the liar. The FBI noted that when people see or are mentioned about someone they like, their pupils dilate, and conversely, when they see someone they dislike, the pupils shrink.

Female colleague Lucy: "Hey, are you interested in Vice President George?"

Female colleague Daisy: "How is it possible, nothing."

Female colleague Lucy: "Stop pretending, it's all written on your face."

Female colleague Daisy: "Ah, what?"

In the example of two people, one of them must be lying.Observe the two people's eyes change very obviously as the conversation continues to deepen.When the female colleague Daisy's pupils involuntarily get bigger as the conversation deepens.Generally speaking, the size of the pupil is affected by the light and shade, and it will also change with the change of the person's interest in a certain issue.

§§§The eyes of liars are more changeable in the second section

The FBI believes that people's eyes are the most likely to reveal people's true feelings, personality, health status, etc.Strabismus and frequent blinking are considered common signs of lying.

Typical signs that people tell a lie are: frequent blinking, looking around aimlessly, eye rolling, etc.Strabismus is the result of the mentality of "don't want others to see through your heart".I feel uneasy because of lying, so I try to collect as much information as possible in order to transfer anxiety or regain a sense of security.

Many people think that looking away is a sign of lying.This, they assume, is because the liar feels guilty, guilty, and anxious, making it difficult to look directly at the person being lied to, so he looks away.However, based on the actual experience of the FBI, this is not the case.

First, the pattern of gaze is rather fluid.When the child is lying, he has a guilty conscience, so his face is red, his eyes are flickering, erratic, and he often looks down.However, it is not so easy for an adult to tell a lie. A liar can stare at the other person's eyes, or even pretend to be very honest and stare at you intently, and lie without blushing.However, if you look carefully, you can also see clues in the staring eyes.

Some liars look away, while others increase the amount of time they spend looking at others.Because the gaze is easily controlled, a liar can use his eyes to reinforce the impression that he is being honest.Knowing that other people perceive gaze aversion as a sign of lying, many liars do the exact opposite, deliberately looking more at the other person to give the impression they are telling the truth.So if you want to know if someone is lying, don't limit yourself to eye contact.Also pay attention when someone is looking at you more intently than usual!
Another putative sign of lying is rapid eye blinking.When we get excited or our minds are racing, the rate of blinking does increase accordingly.The average human blink rate is about 20 times per minute, but when we feel stressed, it may increase by four to five times.People tend to get excited when they're lying, or when a liar is looking for an answer to an awkward question, their minds race.In this case, lying does have something to do with blinking.But we have to remember that sometimes a person blinks quickly, not because he is lying, but because he is stressed.Also, some liars have a very normal blink rate.

Eyes can easily betray a liar. For this reason, the FBI suggests using such a method to judge whether the other party is lying: ask him some detailed questions that must be recalled before he can remember, such as "Which people did you meet on the way to buy clothes that day? Talk to them about something."Observe the other person's eyes at this time: If the other person looks into your eyes and answers immediately without thinking, it means that he is telling a lie that has been made up; if his eyes turn upward and then to the left, it means that he is recalling the truth situation; if the eyes roll up and then to the right, he is telling a lie.

§§§Section [-] Liars often touch their noses
In the FBI's study of liars, an alternative behavior to touching the mouth was touching the nose.By touching their noses, liars experience the instant comfort of covering their mouths without risking drawing attention to what they are doing.In this maneuver, touching the nose is an alternative to covering the mouth.It's a sneaky body language that looks like someone is scratching his nose, but his real intention is to cover his mouth.

This is because when a person is lying, the blood pressure in the nose will rise, which will make the nose swell and stimulate the nerve endings of the nose, so it is necessary to rub the nose to relieve itching.Some experts in the West have made a scientific demonstration of the relationship between the nose and lies: "When a person tells a lie, the erectile muscles of the nose will become congested and swollen, and the swollen nose will itch, forcing the liar to scratch, rub his nose or touch his nose." nose."

There is also an idea that touching the nose is a sign of deceit, but the action has nothing to do with the mouth.One of the proponents of this view, Alan Hirsch, along with Charles Wolfe, provided a detailed analysis of Bill Clinton's grand jury testimony in August 1998, when the president denied ever having sex with Monica Lewinsky had an affair.They found that when Clinton told the truth, he barely touched his nose, but when he lied about his affair with Monica Lewinsky, he touched it every four minutes on average.Hirsch called this "Pinocchio Syndrome," after the famous fairy tale character's life.Every time the character finishes telling a lie, the wooden nose grows longer.Hirsch pointed out that when people lie, the nose will become congested, which can be relieved by touching or rubbing the nose.

However, there are at least two arguments against the "Pinocchio syndrome" claim.One that thinks nose touching is just a sign of nervousness, not a sign of lying.Another point of view is that when people lie, they feel anxious and afraid of being discovered, and these emotions are related to the depletion of blood in the face.In other words, it causes blood vessels to constrict, not dilate.That's the view of Mark Frank of Rutgers University.Frank also points out that experimental research on lying has shown that touching the nose is not a common sign of deceit.Of course, this may be because touching the nose did not appear in the experimental site.The stakes are low there, and even if the lie is exposed, the costs people pay for it are not too high.There's also the possibility that nose-touching isn't a sign of fraud for everyone, and it might just be a trademark body language tactic for some, including Clinton.

§§§The fourth liar scratches his neck and ears
When people are nervous, they always like to grab something to find a sense of security. So do liars. When they lie, they often scratch their necks or ears.

1. Liars scratch their necks

The FBI concluded based on observations that every time people scratch their necks, the index finger usually scratches five times.The number of index finger movements is rarely less than 5 or more than 5 times.This gesture is a sign of doubt and uncertainty, and is equivalent to saying, "I'm not sure I agree with you."

The inconsistency is especially evident when the spoken language does not coincide with the gesture.For example, if someone says "I totally understand how you feel" while scratching his neck at the same time, we can conclude that he really doesn't understand.

2. Liars often scratch their ears
To avoid scolding from their parents, children will cover their ears with both hands, while adults will use the gesture of scratching their ears.There are also many variations of ear scratching gestures, including rubbing the back of the pinna, inserting fingertips into the ear canal to pick out the ear, pulling the earlobe, folding the entire pinna forward to cover the ear hole, and so on.

People may also scratch their ears when they feel they have heard enough or want to speak.

Scratching the ear can also mean that the person is in a state of anxiety.Prince Charles often makes ear-scratching and nose-rubbing gestures as he walks into packed rooms or passes crowds.These movements reveal the nervousness inside him.

§§§The details of the body movements of the liar in Section [-]
People are always nervous unconsciously when they lie, but some good liars are good at covering up, so it is not easy for others to detect.If sitting on a stool, the nervous person will sit shallowly on the front half of the seat, with legs bent and waist bent, as if ready to pop out of the stool to take action at any time; sometimes the legs will keep shaking Rubbing your feet together to distract your attention and reduce the panic in your heart.If you are calm in your heart, you will appear to be slack in spirit, and you will sit firmly on the chair and stretch out your feet at the same time, very leisurely, indicating that you will not stand up immediately.

When the police interrogate prisoners, they like to let the suspect sit in a room with only one chair and no shelter, and then use strong lighting to remove the environmental conditions that are conducive to lying and observe the prisoner's body movements at a glance.

1. Liars often cover their mouths with their hands

The FBI points out that when a person subconsciously covers their mouth with their hands, it means that the liar is trying to restrain himself from telling those lies.Some people fake a cough to cover up their mouth covering gesture.Sometimes people cover their mouths with a few fingers or a clenched fist, but the meaning is the same.

If you hold a meeting in the company and you see the audience covering their mouths when you speak, you should pay attention at this time.In this situation, you should stop speaking and ask the audience, "Do you have any questions?"

2. Liars put their fingers between their lips

Toddlers put their thumb or index finger in their mouths as a substitute for the mother's nipple, while adults put their fingers between their lips, or smoke, hold a pipe, chew gum, hold a pen, or bite glasses frame etc.People often make this gesture in stressful situations.

3. Liars rub their eyes
When a child does not want to see something, he covers his eyes with his hand.And when we adults don't want to see something, we will subconsciously rub our eyes.The brain rubs the eyes in an attempt to prevent the eyes from witnessing deception, doubt, and unpleasantness, or to avoid confronting the person who is being deceived.Movie actors often use eye-rubbing gestures to show the hypocrisy of characters.

A man who is trying to cover up a big lie is more likely to turn his face away.In contrast, women make less eye-rubbing gestures, and they generally just touch gently under the eyes.However, like men, women also turn their faces away when lying to avoid the gaze of the listener.

4. Liars often pull on their collars
The FBI study found that when a person lies, it often causes a tingling sensation in the sensitive facial and neck tissues, necessitating rubbing or scratching with the hands.When the liar feels that the other party suspects him, his neck seems to sweat, and at this time he consciously pulls his collar.

When a person is angry or frustrated, he will also pull the collar away from his neck, so that cool air can pass into the clothes and cool the anger in his heart.When you see someone doing this, you might as well say to him, "Please tell me what you have to say, okay?" or "Please say it again, please?" Such words will make the person who is trying to lie Show his feet.

5. Liars shrug quickly
Shrugging usually conveys two messages of ignorance or indifference: "I don't know" or "I don't care."When people shrug their shoulders, it's usually a sign that they're willing to communicate the message.However, if the shrug is done very quickly, it means something else.

This situation is a bit like a person who is embarrassed by a joke but pretends to think it is funny, then there will be a smirk on his face that only moves his lips instead of a smile on his face.

6. Liars cross their arms
This posture expresses a sense of defense, rejection, and protest, and shows the existence of psychological factors such as contradictions, interaction of multiple situations, or tension.When a person is telling a lie or is afraid that his lie will be exposed, he always has a defensive mentality towards the listener, and he does not want others to approach or obtain any information.When it is inconvenient to express in words, he adopts a certain gesture to show refusal,
