The most accurate visual way of detecting lies is based on the movement of our gaze. They say that " eyes are the mirror of the soul", or "only your eyes can tell the truth", "your eyes don't lie."
Eye movement patterns are considered within the framework of its theory of Neurolinguistic Programming (NLP).
Observing a person, it is not difficult to notice that throughout the entire conversation his gaze is directed in one direction or another. Scientists associate gaze movement with the process of human perception and identify three main channels through which people receive and process information:
Visual channel. It is associated with visual images, everything that we see with our eyes;
Auditory channel. Associated with hearing, the sounds that we perceive;
Kinesthetic channel. All information related to sensations, feelings, smells, tastes, and experiences passes through it.
For each person, one of these channels, as a rule, is the leading one. Some of us live more by images, some by feelings, and some by stories and news and love with our ears! At the same time, each of us uses all systems as needed.
NLP Theory and Practice says:
- Eyes looking up give us figurative ideas.
- The eyes, walking along the horizontal axis, help us perceive and reproduce speech and sounds.
- If the gaze is directed downwards, this is associated with sensations or an internal monologue.
- At the same time: for right-handed people, the left side is the area associated with the past, the right side is associated with the future. For left-handed people it's completely the opposite.
Look at the diagram. It shows the movement of the gaze and the corresponding channel of perception. 
- The gaze is turned upward. It is difficult for a person in this position to think about anything (try it yourself). He's probably just avoiding the conversation and doesn't want to delve into the topic. Moves away
- VC. Look up and to the right (from the side of the interlocutor). Visual design. In this case, the person turns to the future or invents images.
- BB. Looking up and to the left - a person turns to the past, remembers some of his pictures (visual images). Visual recall.
- AK. Looking horizontally to the right - constructing speech, inventing.
- AB. Looking horizontally to the left - a person is in the past, he remembers speeches, words.
- Look down. Most likely the interlocutor cannot hear you. He was completely lost in his experiences.
- TO. Looking to the right and down is an experience, imagining oneself in the place of another;
- VD. Looking down to the left - internal monologue or dialogue, as well as recollection of one’s own experiences.
Let's try. Find someone to talk to who is willing to participate in your experiment. 
First, determine whether he is right-handed or left-handed. It depends not only on the leading hand. A person can also be a hidden left-hander. To determine this, there are special neuro-psychological tests. But at the beginning of the conversation, you can simply ask a security question formulated for the answer “Yes” - the answer to which you know for sure. Observe the oculomotor reaction. It is the very first, perhaps even fleeting, movement of the eye that is important. If it is directed to the memory to the left-up, side or bottom, then your interlocutor is right-handed. And vice versa.
Or: “Ask him to imagine green pancakes topped with red sour cream.” It’s unlikely he’s ever seen such a product. And look at the movements of his eyes, where his eyes often go when constructing an image. Please note that for some moments the gaze may be directed towards the memory of images (for right-handed people this is upward to the left), since a person, when inventing something new, always takes old memories and models them, changing them.
Enter into any dialogue and look into the eyes of your interlocutor and you will easily understand what he is doing now:
Remembers or invents images of familiar people and events;
Remembers stories told and someone’s speeches, or prepares to answer you by composing another phrase to himself;
Or perhaps your interlocutor is lost in his feelings, remembering feelings he once experienced, or he is very worried about your current conversation.
Did you manage to catch the trajectory of your gaze? Then boldly look your interlocutors in the eyes and learn further!
For right-handed people: looking to the right and up, to the right and to the side - that means composing.
For left-handed people it's the opposite.
Important! When you look at your interlocutor, if he has a “right”, then you have a “left”!
In addition, it is worth remembering that lying is accompanied by negative experiences of shame and guilt. This is why a person who is deceiving will most often avoid direct eye contact. At the same time, he can choose the opposite tactic, look straight without looking away. They say about such a case: “He lies and doesn’t blush!”
Then you need sharp vision, which will help you notice the constriction and dilation of the pupil. At the same time, if a person’s pupil narrows, it means he directs his consciousness inward - to memory; if it expands, then to the future, to design, to fantasy.
Remember that to establish the fact of a lie (when you are not yet experienced enough), always pay attention to: posture, facial expressions, gestures, voice, etc.

Our eyes usually follow our thoughts, and sometimes, just by looking into our eyes, other people can understand what we are thinking about. Would you agree that reading another person's thoughts through their eyes is a very useful skill? Thanks to this, everyone will be able to understand whether they are being deceived or determine whether your interlocutor is interested in what you are telling him about. Poker players master this useful skill perfectly.
Eyes to eyes
Such contact with the interlocutor indicates that he is very interested in talking with you. Prolonged eye contact may indicate that the person is scared and/or doesn't trust you. Brief eye contact means the person is anxious and/or not interested in talking to you. And the complete lack of eye contact indicates the complete indifference of your interlocutor to your conversation.
Man looking up
Eyes raised upward are a sign of contempt, sarcasm, or irritation directed at you. In most cases, such a “gesture” means a manifestation of condescension.
If a person looks at the upper right corner
He visually imagines the picture stored in memory. Ask someone to describe the appearance of a person, and your interlocutor will certainly raise his eyes up and look to the right.
If a person averts his eyes to the upper left corner
This indicates that he is clearly trying to imagine something. When we try to use our imagination to visually “draw” some picture, we raise our eyes up and look to the left.
If your interlocutor is looking to the right
This means that he is trying to remember something. Try asking someone to remember the melody of a song, and the person will definitely glance to the right.
Looking to the left, people make up sounds
When a person imagines a sound or composes a new melody, he looks to the left. Ask someone to imagine the sound of a car horn underwater, and they will certainly look to the left.
If your interlocutor lowers his eyes and looks to the right
This person conducts a so-called “internal” dialogue with himself. The person you're talking to may be thinking about something you said, or they may be thinking about what to tell you next.
If a person lowers his eyes down and looks to the left
He thinks about his impression of something. Ask your interlocutor how he feels on his birthday, and before answering you, the person will lower his eyes and look to the left.
Downcast eyes
We show that we do not feel very comfortable or even embarrassed. Often, if a person is shy or does not want to talk, he lowers his eyes. In Asian culture, not looking a person in the eye and looking down when talking is the norm.
These “rules” are generally followed by all of us. But left-handed people do the opposite: right-handed people look to the right, left-handed people look to the left, and vice versa.
How can you tell if someone is lying to you?
There is no absolutely correct algorithm by which you can determine whether your interlocutor is lying or not. The best option is to ask a basic question, such as “what color is your car?” If a person raises his eyes and looks to the right (or left, if he is left-handed), then he can be trusted. Thus, in the future you can understand whether you are being deceived or not.
For example, while telling you about something that happened in class, your friend looks to the right; When talking about his holidays, he constantly looks up and glances to the right. Most likely, everything he said is true. But when he tells you about the beautiful girl he met the other day, and his eyes are directed to the upper left corner, you can conclude that he is clearly “embellishing.”
Today people have learned to hide their emotions as skillfully as possible. Various tricks and manipulations help people play on the feelings of others, deceive and get their way. However, the eyes always reveal what a person actually feels, and any of them turn out to be a failure if the person’s eyes dart around or he blinks rapidly. How can you tell if your interlocutor is lying to you or telling the truth?
Even the most professional self-control will not help if a person is nervous inside or wants to lie. And no matter how hard they try to deceive you, always look your interlocutor in the eyes. There you will see the real truth. So, what are the signs of real emotions?
Eye contact
If you delve into the principles of various success trainings, you will see the advice to keep eye contact with people all the time. And all because a sign of a self-confident person is a direct, piercing gaze. But this trick is used not only by those who really want to show their openness in this way, but also by those people who want to tell a lie. When such a person speaks, he tries not to take his eyes off and seems to hypnotize his interlocutor.
You can check whether he is nervous in a simple way, which also works if you are being “processed” by a fortune teller on the street. You need to make a sharp movement to confuse a person, reports JoeInfo journalist Karina Kotovskaya. If he intended to fool you, then you will notice his fuss and incoherent speech after his high-quality lying monologue was stopped.
The person who intended to lie will begin to move away and behave unnaturally, remembering what else he wanted to say. If the person was truthful, then he will quickly remember the essence of the conversation and continue to express his thoughts without tension.
blinking
When people lie, they reveal their condition without noticing it. They may be confident in the impression they make, but if they are nervous, they simply begin to blink rapidly. This sign is the body's natural reaction to stress. Another reason for blinking is an unpleasant topic of conversation that a person would like to avoid. If a person blinks rarely, this indicates his calmness and good mood.
Eyes to the side
If you want to check whether a person is telling the truth or lying, then make sure when you ask a question whether he looks away from his eyes. If he takes it away, it means he either remembers something and wants to tell the truth, or intends to think through a lie.
Psychologists also emphasize that it is important in which direction the interlocutor averts his eyes. If he does this to the right, then he is lying, to the right and up means that he is thinking through a lie, to the right and straight ahead means that he is replaying his future lying story in his head, and when he looks to the right and down, then he is ready to voice what he says. what I put in my head. But this applies to a right-handed person. If the interlocutor you need to analyze is left-handed, he will look the other way according to the same pattern.
You can also identify a lie if you notice that the interlocutor, speaking to you, runs his eyes from one object to another.
Pupils
Particular attention should also be paid to the pupils if you want to learn how to read a person’s condition from the eyes. And all because it is not physically impossible to control the contraction and expansion. So, when a person lies, his pupils narrow, and red spots form around the eyes, due to the fact that the person is stressed and blood begins to rush to the face. If a person tells the truth, then the pupils dilate or remain in their normal state.
Remember that well-being is hampered and even the smallest changes in outlook can reveal not only insecurity, but also outright lies. And if you have noticed more than once that you are being lied to, think about it: perhaps at one time you also ran your eyes from object to object and blinked intensely. Not only do you love the truth, those around you also prefer sincerity.
Where does a person look when he lies? How can the direction of gaze indicate that a person is lying? These two questions were previously asked by our readers in the comments on the site.
The short answer to these questions is, "to a certain extent." It's not as easy as recent TV shows or movies make it out to be. There, a detective is able to determine whether a person is lying simply based on whether he is looking to the right or to the left when he speaks. In fact, it would be foolish to jump to such quick conclusions without further investigation... but a certain technique can achieve something.
So... read, think about it, and test it on your friends and acquaintances to understand for yourself how reliable it is.
The look shows the strength of the soul.

Visual Assessment Keys - "Lying Eyes"
As far as is known, the first use of the term "Visual Appraisal Keys" was by Richard Bandler and John Grinder in their book Frogs into Princes: Neuro Linguistic Programming. Based on their own experience, they found the following:When a "normally organized" person (who is not left-handed) is asked a question, he directs his gaze in one of six directions, as seen from the side of the questioner, looking at him:
1. Up and left
Indicates visually created images (VS)
If one is asked to imagine a "purple buffalo", then while the person is thinking about the question, imagining a "visually created" purple buffalo in his mind, his eyes will turn in that direction.
2. Up and right
Indicates visually recalled images (VR)
If you ask a person, "What color was the first house you lived in?" their eyes will turn in that direction as they think about the question, "visually remembering" the color of their childhood home.
3. Left
Indicates auditory created images (SS)
If someone is asked to imagine the highest possible sound, then when he thinks about the question, "creating an auditory image" of a sound that he has never heard, his gases will turn in that direction.
4. Right
Indicates auditory recalled images (ER)
If you ask a person to remember what his mother's voice sounds like, then when he thinks about the question, trying to remember the sound, his eyes will turn in that direction.
5. Down and left
If you ask someone the question “Can you remember the smell of a fire?”, this is the direction in which their eyes will turn when they think about the question, remembering the smell, sensation or taste.6. Down and right
Indicates own dialogue (D)
A person's eyes turn in this direction when he "talks to himself."
How can gaze information be used to detect lies?
Example: Let's say your child asks for cookies, and you ask him: “Did mommy allow it?” The child answers: “Mom said... it’s possible,” but at the same time looks to the left. This may indicate that he is coming up with a response, as his eyes show "creating an image or sound."Looking to the right will indicate "remembering" a voice or image, in which case he is probably telling the truth.
Concluding remarks
- A forward gaze or unfocused and non-moving eyes are also considered a sign of visual evaluation.
- Typically, a left-handed person will exhibit the opposite sense of eye direction.
- As with other signs of lying, it is necessary to first find out and understand the basis of a person's behavior before concluding that he is lying based on the direction of his gaze.
Many critics believe that all of the above is just nonsense. However, practice shows that there is something in this. But who's stopping you from finding out for yourself?
It is enough to make a list of questions like the ones above and offer them to friends and relatives who will play the role of test subjects. And then watch their eye movements and record the results.

If your interlocutor is looking right, this means that he is trying to remember something. Try asking someone to remember the melody of a song, and the person will definitely glance to the right.

By learning to control his gaze, a person can force others to trust him unconditionally. (How can you lie while looking a person straight in the eyes?)
