Become a Human Lie Detector

This knowledge is also useful for managers, employers, and for anyone to use in everyday situations where telling the truth from a lie can help prevent you from being a victim of fraud/scams and other deceptions.

This is just a basic run down of physical (body language) gestures and verbal cues that may indicate someone is being untruthful.

Body Language of Lies:

• Physical expression will be limited and stiff, with few arm and hand movements. Hand, arm and leg movement are toward their own body the liar takes up less space.

• A person who is lying to you will avoid making eye contact.

• Hands touching their face, throat & mouth. Touching or scratching the nose or behind their ear. Not likely to touch his chest/heart with an open hand.

Emotional Gestures & Contradiction

Timing and duration of emotional gestures and emotions are off a normal pace. The display of emotion is delayed, stays longer it would naturally, then stops suddenly.

• Timing is off between emotions gestures/expressions and words. Example: Someone says "I love it!" when receiving a gift, and then smile after making that statement, rather then at the same time the statement is made.

• Gestures/expressions don’t match the verbal statement, such as frowning when saying “I love you.”

• Expressions are limited to mouth movements when someone is faking emotions (like happy, surprised, sad, awe, )instead of the whole face. For example; when someone smiles naturally their whole face is involved: jaw/cheek movement, eyes and forehead push down, etc.

Interactions and Reactions

• A guilty person gets defensive. An innocent person will often go on the offensive.

• A liar is uncomfortable facing his questioner/accuser and may turn his head or body away.

• A liar might unconsciously place objects (book, coffee cup, etc.) between themselves and you.

Verbal Context and Content

• A liar will use your words to make answer a question. When asked, “Did you eat the last cookie?” The liar answers, “No, I did not eat the last cookie.”

•A statement with a contraction is more likely to be truthful: “ I didn't do it” instead of “I did not do it”

 Liars sometimes avoid "lying" by not making direct statements. They imply answers instead of denying something directly.

• The guilty person may speak more than natural, adding unnecessary details to convince you... they are not comfortable with silence or pauses in the conversation.

• A liar may leave out pronouns and speak in a monotonous tone. When a truthful statement is made the pronoun is emphasized as much or more than the rest of the words in a statement.

• Words may be garbled and spoken softly, and syntax and grammar may be off. In other
words, his sentences will likely be muddled rather than emphasized.

• The use of distancing language. 

Other signs of a lie:

• If you believe someone is lying, then change subject of a conversation quickly, a liar follows along willingly and becomes more relaxed. The guilty wants the subject changed; an innocent person may be confused by the sudden change in topics and will want to back to the previous subject.

• Using humor or sarcasm to avoid a subject.

Final Notes:

Obviously, just because someone exhibits one or more of these signs does not make them a liar. The above behaviors should be compared to a persons base (normal) behavior whenever possible.

Most lie detecting experts agree that a combination of body language and other cues must be used to make an educated guess on whether someone is telling the truth or a lie.

Eye Direction and Lying

Eye Movement and Direction & How it Can Reveal Truth or Lies 

This is a continuation of our previous article Detecting Lies. Many comments by our visitors asked about how eye direction can indicate the presence of a lie.

Can the direction a person's eyes reveal whether or not they are making a truthful statement? Short answer: sort of. But, it isn't as simple as some recent television shows or movies make it seem.

In these shows a detective will deduce if a person is being untruthful simply because they looked to the left or right while making a statement.

In reality, it would be foolish to make such a snap judgment without further investigation... but the technique does have some merit.

So, here it is... read, ponder and test it on your friends and family to see how reliable it is for yourself.

Visual Accessing Cues - "Lying Eyes"

When asked a question a "normally organized" right-handed person looks (from your viewpoint, looking at them):

Up and to the Left 

Indicates: Visually Constructed Images (Vc)
If you asked someone to "Imagine a purple buffalo", this would be the direction their eyes moved in while thinking about the question as they "Visually Constructed" a purple buffalo in their mind.

 Up and to the Right 

Indicates: Visually Remembered Images (Vr)
If you asked someone to "What color was the first house you lived in?", this would be the direction their eyes moved in while thinking about the question as they "Visually Remembered" the color of their childhood home.

To the Left 

Indicates: Auditory Constructed (Ac)
If you asked someone to "Try and create the highest the sound of the pitch possible in your head", this would be the direction their eyes moved in while thinking about the question as they "Auditorily Constructed" this this sound that they have never heard of.

To the Right 
Indicates: Auditory Remembered (Ar)
If you asked someone to "Remember what their mother's voice sounds like ", this would be the direction their eyes moved in while thinking about the question as they "Auditorily Remembered " this sound.

Down and to the Left 
Indicates: Feeling / Kinesthetic (F)
If you asked someone to "Can you remember the smell of a campfire? ", this would be the direction their eyes moved in while thinking about the question as they used recalled a smell, feeling, or taste.

Down and To the Right 
Indicates: Internal Dialog (Ai)
This is the direction of someone eyes as they "talk to themselves". 

The Gist of it...

How this information is used to detect lies:

Example: Let's say your child asks you for a cookie, and you ask: "Well, what did your mother say?" As they reply "Mom said... yes.", they look to the left. This would indicate a made up answer as their eyes are showing a "constructed image or sound. Looking to the right would indicated a "remembered" voice or image, and thus would be telling the truth.

Final Notes:

*** Looking straight ahead or with eyes that are defocused/unmoving is also considered a sign of visual accessing.

*** A typical left-handed person would have the opposite meanings for their eye-directions.

*** As with other signs of lying, you should first establish and understand a persons base-behavior before concluding they are lying by the direction of their eyes.

*** Many critics believe the above is a bunch of bull***t. In my own experiments I have found these techniques to be more true than not. But, why not find out for yourself? Make up a list of questions that like the sample ones, and give them to your friends/family anyone who would be your guinea pig, observe their eye movements and record the results.

*** This guide is hardly in-depth, I recommend getting the book "Frogs into Princes: Neuro Linguistic Programming" by Richard Bandler and John Grinder for a more thorough explanation if the subject interests you.

Micro Expressions, Subtle Body Language and Lying

Is the show "Lie to Me" for real?

I am not a police interrogator, scientist, or other expert... I am however a mother & people watcher.

Years ago, when I wrote articles on How to Detect Lies & Eye Movement and Lying -- I knew of the Micro expression theory, but had a difficult time researching the subject well enough to relay it into an article.

Recently, I've come across tons of new research, websites, articles, videos, etc. about micro expressions and believe anyone who reads my old articles about lying & body language would benefit from micro expression research and theory.

What are Micro Expressions?

A micro expression is a momentary involuntary facial expression -- that people unconsciously display when they are hiding an emotion. They are quick & intense expressions of concealed emotion.

The main points to remember are that micro expressions are:

Brief - Micro-expressions can appear then disappear off the face in a fraction of a second. In other words micro-expressions occur so quickly, that most people don't even notice them.

Involuntary - A micro-expression is caused by involuntary movements in facial muscles. Most people cannot control these involuntary muscles which are affected by their emotions.

Micro Expressions are generally grouped into seven universal emotions: anger, disgust, fear, sadness, happiness, surprise, and contempt.

A Brief History of Micro Expression Theory

According to Wikipedia - Micro Expressions were first discovered by Haggard and Isaacs in the 1960s. In 1966, Haggard and Isaacs outlined how they discovered these "micromomentary" expressions published under the title: "Micromomentary facial expressions as indicators of ego mechanisms in psychotherapy".

Although it is not included in most histories of micro expressions; I would like to point out that Darwin's book "The Expression of the Emotions in Man and Animals" published in 1872 deserves a mention.Darwin noted the universal nature of facial expressions, the muscles used in facial expressions, etc. 

Most websites I can find next list William Condon as a pioneer who studied hours of tapes in the 1960s frame by frame to discover micro movements like micro expressions. I can find little info on this research but there is some other interesting body language & verbal expression / NLP research by a Dr. William S. Condon  (I'm 99% sure it's the same dude - contact me if you have any info on the 1960s micro expression research by Condon as cited on wikipedia). Others mentioned as pioneering researchers in the field include John Gottman and Paul Eckman.

Dr. Paul Ekman's research (along with the work of Silvan Tomkins ) in the study of emotions and their relation to facial expressions took Darwin's work to the next level proving that facial expressions of emotion are not culturally determined, but biological in origin and universal across human cultures. Eckman co-developed the Facial Action Coding System (FACS)  with Wallace V. Friesen in 1976. FACS is a system to taxonomize human facial expressions, and still used today by psychologists, researchers and animators.

Detecting Deception Using Statement Analysis®

How People's Words Betray Them

Introduction by Blifaloo: I am super excited to introduce my readers interested in lie detection to "Statement Analysis®" -- a technique used by police and other investigators to determine the truthfulness of written or spoken words.

Guest author Mark McClish is a well-respected retired Deputy United States Marshal, and an expert in interviewing techniques. You'll find more info & links about his research at the end of this article.

Intro to Statement Analysis

Statement Analysis is the process of analyzing a person’s words to determine if the subject is being truthful or deceptive. The reason these techniques work is because people’s words will betray them.

There are usually several ways you can phrase a statement. People will always word their statement based on all their knowledge. Therefore, their statement may include information they did not intend to share.

It is nearly impossible to give a lengthy deceptive statement without revealing it is a lie.

The Statement Analysis techniques are very accurate because they are based on the English language specifically word definitions and the rules of grammar. For example, when a person states, “I am trying to be honest” he is telling us he is not being honest. The word “tried” means he is only attempting to be truthful. When a rape victim uses the pronoun “we” in her statement she is revealing she is being deceptive. The pronoun “we” not only shows plurality but it also means a partnership was formed. We would not expect a rape victim to partner up with her attacker. When a person uses phrases such as “later on” or “afterwards” he has withheld some information by skipping over something in his story.

An example of utilizing the rules of grammar would be to analyze the verb tenses in a statement. When a person is telling us what happened, he is required to speak in the past tense. Therefore, if present tense language appears in his statement, this is a sign he is making up the story. Consider the following statement:

“I was sitting in my car when a man opened my door, 
pointed a gun at me and tells me to get out.”

While the person starts out using past tense language, he switches to present tense language with the word “tells.” The present tense language is an indication he is not drawing his story from memory.

Another example of using the rules of grammar to detect deception is how a person uses articles within his statement. When we introduce someone or something that is unknown, we are required to use the indefinite articles “a” or “an.” Once the introduction has been made, we then use the definite article “the.” We see this in the following statement:

“A man approached me and pointed a gun at me. 
He stuck the gun in my ribs and forced me into the car.”

In the first sentence, the victim properly refers to the attacker and the weapon as “a man” and “a gun.” Having identified the gun, he then correctly refers to it as “the gun” in the second sentence. A problem arises when he refers to the vehicle as “the car.” Since this is the first time he mentions the vehicle, he should have called it “a car.” Using the article “the” tells us the victim either recognized the car or he is making up the story.

Many times the truth goes unnoticed because people like to interpret what a person has said. However, you should never interpret. First, one cannot read someone else’s mind. Secondly, people mean exactly what they are saying.

We see a good example of this with O.J. Simpson’s so called suicide letter. This was the letter that was discovered when Simpson failed to turn himself into the police. The letter starts out saying, “First everyone understand, I had nothing to do with Nicole’s murder.” That is how you heard it read on television. That is how you saw it printed in the newspapers and magazines. The problem is that is not what Simpson wrote. In his letter, he crossed out the words “I had.” His letter actually reads, “First everyone understand, nothing to do with Nicole’s murder.”

He took himself out of the denial.

So, why do most people include the words “I had?” Most likely because they believe this is what Simpson meant. However, people mean exactly what they say or in this case write. Simpson meant to cross out those words.

By using the Statement Analysis techniques, you can determine exactly what people are telling you. This allows you to obtain additional information that sometimes goes unnoticed. These techniques will also show you if they are lying or telling the truth.
