Lie Detection

Lie Detection Techniques

There are five major categories that are used to detect a lie, these are;

Many people who lie give themselves away by eye patterns, cadence of speech, body language, and emotional gestures.

Almost all liars will do something that will fall under these 4 categories. This is applies to most people, but not everyone. Habitual liars are so used to lying, that they begin to believe themselves. If you believe what you are saying, you do not exhibit the body language of a liar, emotional gestures of a liar, or eye patterns of a liar. However, people with a sense of integrity will subconsciously express their guilt through their movements or speech.�

Top 5 myths about Lying

1. ) The biggest and most renown myth is the myth that someone is lying or deceiving you because they are fidgeting, or not maintaining eye contact.

2. ) An individual is lying because he/she is replying with curt responses.

3. ) It is particularly difficult to detect lies that your close friends or family tell.

4. ) An individual is lying because he/she looks content, or appears to be smiling.

5. ) If someone fails a polygraph, they are lying.

Myths debunked

1. ) This myth is debunked in the eye patterns of a liar section. There is a myriad of reasons why someone could be avoiding eye contact. For example: something behind you caught their attention, they have social disabilities, or something as simple as embarrassment.

2. ) This myth is unambiguously false. In fact, short and pithy responses are excellent indications that someone is NOT lying. The more someone elaborates on their story, and adds unnecessary details, the greater the chance he is lying.

3. ) This is also another myth that needs to be debunked. It is not anymore difficult to detect lies that your close friends or family tell. In fact, its actually much less difficult to detect a lie from a family member or close friend, rather then a stranger. Why? This is because you are aware of all their natural habits, and when they break their natural habits you know some thing is wrong. Knowing how to tell if a stranger is lying is much more difficult then your family or close friend.

4. ) How many times have you been told, “your lying, I can see it all over your face.” Well most of the time when they say, “I can see it all over your face” they are referring to that big grin spread across your face. Think about this: why would someone smile if they are lying? If someone really is truly lying, then wouldn’t they try to deceive you and not make it so perceptible?

5. ) It’s true, the polygraph is an admirable tool when you think someone is lying. Yet, the much vaunted polygraph is not impermeable. A polygraph is only accurate less then 95% of the time. In addition, people have discovered ways to “cheat” on the polygraph. Some people even go to such an extreme as to take pills to help them relax, which precludes the possibility of accurate results. Lastly, it is possible for an individual to have polygraph training, which allows them to easily pass a polygraph.

There are thirteen different lies a person may commit. When someone commits a lie, it can be catagorized as either:


When someone submits a statement as the truth, but does not know if the statement is actually the truth.

Bold- faced lie

A bold face lie is a lie that is told, but is obvious to everyone listening/reading

Lying by omission

Lying by omission is a lie when you state the truth, but you leave something out. Have you ever heard the phrase,” it’s till lying if you don’t tell all of it”? Well that is an example of lying by omission.


A lie that makes a mature subject acceptable to children.

White Lie

A white lie would cause no harm if discovered, and is usually beneficial to the liar and the hearer. White lies are often used to avoid offence.

Noble Lie

A noble lie is a lie that will cause great discord if uncovered, and usually has the effect of helping someone maintain power.

Emergency lie

A strategic lie told in dire situations.


Lying under the oath


Pretending to have an intention or capability that someone doesn’t actually have.


Stretching the truth.

Jocose lies

Teasing or sarcasm

Contextual lies

Stating something in a particular context. The statement may be true, but without complete information it gives a false impression. A contextual lie may also be a misleading tone in your voice.

Promotion lies

Advertisers lie or exaggeration such as: “You will love our product”�

Using Eye patterns to detect lies

Have you ever been accused of lying just because you refused to make eye contact with someone? Well it’s not if you’re not looking, but it’s where you’re looking that gives you away. Every time you look in a direction, there is a reason, it’s not just a coincidence. Your subconscious mind is responsible for this. Before determining if someone is lying by just their eye patterns, be sure you get to know their natural movements. Remember, there are exceptions in everything. The six different eye patterns listed below are the average person’s natural habits. Statistically speaking, most peoples eye patterns match the patterns below. Be careful, because not everyone is average. Their is a small percentage of people who’s eye patterns are reversed, so you should get to know their normal eye patterns first.

To the right– When a persons eyes look to the right, they are constructing an auditory thought. (your left)

Example #1: Tell someone to think of the noise of thunder and watch their eyes. They will move to the right as they attempt to listen to the noise of thunder in their mind.

Example #2: think of the sound of church bells

Up and to the left– This indicates a visually remembered image. (your right)

Example#1: Ask someone to remember the color of their house, and watch as their eyes quickly move up and to the left. In their mind, they are visually remembering the color of their house.

Example #2: What did you wear yesterday?

Up and to the right– This eye movement indicates a visually constructed image. (your left)

Example #1: If you ask someone to picture a sailboat sailing on the ocean, this will be the direction their eyes will move.

Example#2: Picture a giant ice cream with a scoop of every single flavor.

To the left– Looking to the left is an indication of an auditory memory. (your right)

Example #1: Ask someone to listen to their favorite song in their mind, and they will look in this direction.

Example #2: Remember the sound of your father’s voice.

Down and to the right– Typically this is an indication of someone creating a feeling or sensory impression. Their eyes will move this way when they are trying to recall a taste, smell, or feeling. (your right)

Example #1: For example, ask someone to remember their last meal, and watch as their eyes move down and to the left.

Example #2: How does it feel when you walk barefoot on mud?

Down and to the left– This is the direction someone’s eyes will move while they “talk to themselves” (your left)

� The above eye patterns are typically used when someone gives an extended response to an answer. It is impossible to use these when a person replies with a yes or no answer. If a person replies with a yes or no answer, watch their eyes carefully. A person replying with a yes or no response that is lying will usually close their eyes very briefly, maybe half a second, then respond.

How does this help me detect a lie? Typically, if you ask someone a question and they glance to the right (your left) they are creating something, or in other words lying. When someone looks to their left (your right) they are recalling something, and are telling the truth. Of course their always will be exceptions to these eye patterns, as their are exceptions in everything. The most vital thing to do to be the most accurate would be to get to know their normal eye patterns first and to make sure that this person is not an exception. Also, do not think you can detect a liar solely based on their eye movements, you will need to put forth some common sense while you are contemplating on whether or not they are lying. The eye patterns of left-handed people may be reversed. �

Cadence of Speech

There are many different tactics one can use while trying to catch a liar. Nothing is going to work 10 out of 10 times, but there are patterns that you may find. Patterns in their eyes, patterns in their movements, and patterns in their speech. When there is an irregularity in their patterns, something is obviously wrong. Below are the most common irregularities in ones speech while they are lying.

� Think back to the last time you were falsely accused of lying. How did you react? How did you feel? When falsely accused of lying, the average persons normal tendency is to be overcome with fury from the false accusation. This is because they are trying to defend their pride or honor. A normal persons response would be something like “How dare you accuse me of such a thing!” However, a liar will not attempt to protect his honor. A liar will focus exclusively on attempting to convince you that they are not lying. A liars response will generally over use the word “no”.

� A liar will repeat the question for reassurance.

Example: Where you at this party last night? Answer: No, I was not at that party last night. If the person was telling the truth, they would just say no.

� Responses using contractions are more likely to be truthful.

Example: Did you take the last cookie from the cookie jar?

Response: No I didn’t

Liars response: No I did not

� Liars will sometimes imply answers instead of denying them.

Example: Did you send him on a wild goose chase?

Answer: Would I really do that?

� A guilty person is not comfortable with awkward silences and pauses, therefore making them talk more then usual. They think by adding unnecessary details, it will help them convince you.

� Some liars will attempt to use humor or sarcasm to either avoid a subject, or avoid answering a question truthfully.

� Some liars may talk very fast because they want to get the lie over with.

Body language of A liar

In certain situations, you can tell a lie not by what you hear, but what you see. A Person’s physical movements will give him/her away every time. Just like the human eye, every movement has a reason backed up behind it. If you can read body language, you will gain the upper hand in any confrontation. The liar will not know he is giving himself away by making certain body movements, because they are all done subconsciously. The subconscious mind is a powerful part of your brain that the average person under estimates. A lot of the movements you make are orchestrated by the subconscious mind.

Knowing what each body movement means is so important because if you can observe some ones body language, then you can decipher it and ultimately decide whether or not the person is lying, or telling the truth. Below are the most common traits of a liar.

Body Language Of A Liar:

� Liar’s physical movements will be limited and stiff.

� Little arm and hand movement

� In some cases, they will avoid eye contact. There could also be numerous other reasons they are avoiding eye contact. Some people may have social disabilities, or it may even appear they are avoiding eye contact, but they are just looking at something. Other reasons could be cultural, or someone is embarrassed. You have to take all these factors into account before you make a judgment. The best thing you can do when someone is avoiding eye contact is to think about the persons normal behavior. If he normally maintains eye contact when he talks to you, and all the sudden he breaks it that might be a little suspicious.

� Hands are more likely to touch their face or mouth.

� More likely to scratch behind their ear, or touch their nose

� Not likely to touch his chest with an open hand

� Sometimes they will shake their heads no as if their saying no but they say yes. This is a subconscious movement, so it means they don’t believe in what they just said. Have you ever seen someone so disgusted at someone, and all they can do is just shake their head? Sometimes liars will look like this when they are speaking.

� Palms will face down when they are lying, because the subconscious mind thinks you are more vulnerable when your palms are face up.

� Some will place objects between you and themselves, this subconscious act is to create a barrier between you and the liar. It helps give them more reassurance. Be aware of the smallest things they place between you and themselves, such as cups, utensils, chairs, and more.

� Some people may be described as “illustrators.” An “illustrator” is a person who uses him/her hands while talking, giving hand gestures to aid them in describing something. While an “illustrator” is lying, their hand gestures become drastically less frequent, or even halt completely.�

� Licking your lips after saying something is a strong sign of deception. When people get nervous, their saliva glands cease to produce saliva, and our mouths become dry. There are two reasons why a person could lick their lips after saying something. They are either nervous, or are uncomfortable with what they just said. �

� Touching the collarbone. When a man touches his collarbone while speaking, or being spoken too, it signals insecurity. This subconscious movement is unusual for men. However, when women touch their collarbone it indicates stress.�

Just because the person exhibits 1 of these behaviors does not mean they are lying. If they are exhibiting 3 or 4 of them, chances are he is. Just remember, to think about their normal behavior while you decide if they are lying. �

Emotional Gestures and Contradictions

Observing emotional Gestures and contradictions can tell you a lot about a person. The most significant thing it does is tell you if someone is faking an emotion. People fake emotions all the time. They do it for several reasons, most are justified

People will fake emotions to please someone. For example, smiling while receiving a gift they do not like. You would be able to tell the person is faking it just by observing their smile, because a natural smile uses more muscles then a fake smile. People will fake emotions for other reasons such as safety, to fit in, or even to obscure their insecurities. Regardless of the reason, fake emotions are very simple to distinguish once you know how.

Using the information below, you can ferret out almost all fake emotions.

� Timing and duration of emotional gestures and emotions are off a normal pace. The display of emotion is delayed, stays longer then it would naturally, and then stops suddenly. This indicates the person is faking his/her emotions

� Some gestures and motions timing will be off.

For example: when someone told you their having a surprise party for you and you walk in and act surprised before or after they yell surprise.

� Gestures/emotions don’t go along with what they are telling you.

Example: Smiling while saying, “that is so sad”

� When someone is faking their emotions, their facial expression is limited to a mouth movement. For example: when someone smiles for real, their whole face is involved, but when they fake smile, mostly the mouth is involved.

� When a person attempts to conceal anger, or any strong emotion, their face will display the emotion for a split second. These expressions are called “micro expressions.” Very few people ever notice these because they are so inconspicuous.

� The micro expressions are universal. Every person on Earth will display the same micro expressions while attempting to conceal specific emotions.

� Some muscles located in your face are not under conscious control. Thus, your face will display these micro expressions and you will be completely oblivious.

� People will subconsciously catch micro expressions, but since they have not been trained to decode these micro expressions, they will be oblivious that they saw them. When people claim that they have a “gut feeling” that someone is lying, it’s because they subconsciously catch these micro expressions. These micro expressions are below the threshold of conscious awareness for most people, and consequently the average person can not identify them, or even establish that they even saw them.

With this information you should now be able to determine whether someone is sincerely “happy for you” when you win money or accomplish something, and if someone is truly sad about your adversity. If you ever catch someone with contradicting emotional gestures, under most circumstances you probably should not confront them about it. They will always deny it, and the person will end up getting mad at you.


This section contains information that did not belong in other sections, so it has its own section. This section talks about the legendary eye contact myth. For some reason, this myth has not been abolished, and has been around for ages. People think that if you do not maintain eye contact you are lying. This is only true in certain cases, you will have to read further to find out more.

Lie detection is tricky to apprehend, but if you apply everything you learn, you will rarely be lied to again! A wise man once said “Knowledge is not power until it is applied”. You may know everything in the world, but if you do not use that knowledge it is worthless.


� Lying takes longer than telling the truth, so the time to answer may indicate a lie. Lying will take longer because liars need more time to think of an elaborate and plausible story.

� A liar will try to avoid eye contact because lying goes against their moral code. Looking someone in the eye is an intimate act. Liars find it hard to maintain eye contact for long periods of time, if at all. People can look you in the eye and lie, but when someone knows their in a great amount of trouble or they know their guilty, they have a much harder time looking you in the eye as they lie due to eagerness, anxiety, and agitation.

� Contradicting the last statement, some liars may make AN EXCESSIVE amount of eye contact, to try to be more believable. You just have to know their natural behaviors to decide which behavior is irregular.

� Everyone has their own baseline – pattern of behavior, and basically if this person breaks their baseline their lying

� Professionals use the changing subject technique to ferret out liars. Someone who has been lying about a subject will become more relaxed, and will welcome this change in subject. A person who is telling the truth will have a cryptic expression on their face when you change the subject, and will try to direct the conversation back towards that subject.�

How to tell if a person is bluffing�

� When someone is bluffing, they are trying to desperately manipulate everyone they are confident and or have an advantage when they don’t. The average person falls for this bluff, because they think “If he is acting so confident, he must have an advantage.” Think about this: if a person truly is so confident, they would feel no need to portray it.

� Think of it like a game of poker. If a person has a good hand, why would he act confident? Any rational person would act like they have a poor hand, so people would add more money to the pot.

� More often then not, an ample display of confidence is a unambiguous sign of bluffing, because if someone is truly confident they would feel no need to convince other people they are.

Here are the four lie detection techniques:

Making up a fact – technique number 1

Step one

After listening to someone’s story, if you believe he or she is deceiving you, ask your friend a very specific detail pertinent to the story that he or she could not possibly know unless he or she was telling the truth.

Example: Your friend tells you that he picked up a really pretty girl and she was really into him. You ask him what her name was. He says a name.

Now to tell if he’s lying, this is what you do. As soon as you hear the name you pretend like you know her, and you can introduce an assumption by saying “oh yeah, I know her we used to be best friends when we were little. I just saw her recently. Does she still have the nose ring and the tongue piercing?(you are completely making this up)

Step two

Let their be a silence and watch carefully how he reacts

If he goes along with your little fake story, and says “yeah that’s her!” Your once trustworthy friend is now a liar. If he says I have no idea what you’re talking about, he probably is not lying.

Second example:

You ask your girl friend where she was last night. She responds by saying she was just at her friend Samantha’s house.

Step 1.) “Oh god I heard what happened were you their when it happened?”

She will say when what happened. “When the blankets on her bed caught fire, thank god she put it out before the whole house burned down.”

Step 2.)Watch her react. “Yes I was, it was horrifying!” SHES LYING!!! She wasn’t at her friend’s house.

Lie Detection Technique number 2

If you think someone lied about a subject, make sure you get their attention, speak clearly, and hit them with a question pertaining to that subject out of the blue. If their answer is “what”, or “huh” they are most likely lying. Saying these things is a defense mechanism, and as you’re restating the question their using that time to come up with a plausible response.

Important note: Wait a minute until the subject has passed, it is important to make sure the person you are asking is not still thinking about the subject.

Remember, it is important that you time these lie detection techniques right.

Lie Detection Technique number 3

Professionals use the changing subject technique to ferret out liars. If a person’s mien is off, and they are appearing to be deceptive, then you should change the course of the conversation, and switch topics very abruptly. Someone who has been lying about a subject will become more relaxed, and will welcome this change in subject. After you change the subject, watch attentively as their face lightens up. A person who is telling the truth will have a cryptic expression on their face when you change the subject, and will try to direct the conversation back towards that subject.

Lie Detection Technique number 4�

This lie detection technique may seem like common sense, but it is an extremely effective and powerful tool in your arsenal. This is what you do:

Allow your suspect to do a full recount of the story, and listen closely to the sequence of events in the story. Afterwards, politely ask him to tell the story once again, but this time have the person recount it backwards. The person may give you a belligerent response, because the request may sound very outlandish.

You must be persistent, and once he does recount the story backwards, listen for any discrepancies in the story, or discrepancies in the sequence of events. Unless this person has an unbelievable memory, their will be many discrepancies in the sequence of events if he is lying. It is extremely difficult to recall events backwards in the same sequence if you made them up.

If you do not believe this technique works, ask someone you know to make up a story. Then tell them to say it backwards. Watch as they grow frustrated, and give up.�
