If there were a sign that signalled to others that that person is lying, they would not do it. However, there isn’t one. No one piece of nonverbal communication can tell us if someone is deceiving us or just lying. People would like lie if there were. 

The only way we can tell if someone is lying to us is by looking for tell-tale signs of deception. We need to learn to read facial expressions, body movements, tone, and cadence of voice before we can make a decision if that person is lying to us. Spotting deceit requires understanding what behaviour’s a liar will exhibit as they make up their story.

It is not an easy thing to catch lies.

Why Words Are Less Important Then You Think

Why Words Are Less Important Then You Think

Facial expressions, voice inflection, posture, breathing habits are all important factors to consider when reading body language.

These different sources may transmit information simultaneously and at the same time, competing for the attention of a lie catcher.

It’s only natural that the lie detector needs to focus on areas where there are signs of possible dishonesty or discrepancies in testimony.

Not every source of information in a conversation is equally reliable. Some sources leak more than others.

Most people are more focused on the least trustworthy sources, such as words and facial expressions and so are easily misled.

A study has shown that most liars don’t try to cover up all of their actions and tell themselves it’s believable. In most cases, people probably wouldn’t be capable of doing so even if they were trying.

People who lie try to keep what they’re hiding from being seen by the person they’re lying to.

Those who lie typically try to be more careful about their choice of words. Most people learn early on in life that people listen closely to what is said, so liars are often cautious about what they say.

Words are the most effective way to communicate because they can convey so much more than any other medium. Covering more topics in less time is an area where words allow you to excel.

Liars tend to edit their speech so as not to expose sensitive material. They do this both because they know it’s possible that you’re paying close attention and because they know they’ll be held more accountable.

The Face

The Face

People will often say things about how you look, including to your face. You may hear things like they gave me a sideways glance, they are checking me out, etc.

People usually focus on a face, something that’s meant to symbolize what really makes us who we are. It distinguishes us from other people and is often the first thing we see upon meeting a person

People pay a lot of attention to faces. The face can display emotions and can communicate how the speaker feels about what they’re saying.

Making eye contact is an important part of a conversation. If someone’s looking your way, it might show that they’re paying attention and understanding what you say. But there are exceptions to the rule: sometimes people will smile or nod while not really listening to what you’re saying.

Liars often monitor which aspects of their words or body language people might focus on more. When speaking, they will usually answer in a manner that will seem more believable for this reason.

It is important to pay attention to the signs of deceitful behavior since words are not always the best place to look. The face is usually better for this since it connects directly with areas of the brain related to emotions and words do not;

For example, emotions such as anger may affect our faces involuntarily. However, we can learn to control these expressions by habit or intentional choice.

One of the most accurate ways to figure out if someone is lying is through their body language. You can evaluate this by noticing if there are any changes from their baseline or normal behavior.

There is a lot of information out there on the internet and elsewhere on how to spot a liar, but we’ve compiled the most common signs below.

The Face Can Be a Valuable Source of Information

People use their facial expressions to express a range of emotions, but there’s no way of telling when they’re telling the truth or lying.

Lying typically involves sending one message and hiding another. This is often done by showing one face but concealing another.

Sometimes people lie and sometimes they tell the truth. One major way to find out is to look for a facial expression – a lie might be betrayed by a face that looks fake, while someone telling the truth often can’t help but have some feelings leak through.

False but convincing expressions may occur one moment and concealment of said expressions happen the next.

It is even possible for the felt and false facial expressions to be shown in different parts of the face within a single blend expression. Most people are unable to detect lies by looking at the face because they are unsure of how to distinguish between false facial expressions.

The true, genuine expressions of emotion are caused by uncontrolled facial movements.

It is possible to voluntarily control the face for communication, although this does not make communication any more reliable.

Is Yawning A Sign Of Lying

Is Yawning A Sign Of Lying

Nope. Yawning by itself is not indicative of deception.

When someone yawns they are opening their mouth wide. This makes it hard to lie because the person now has to move their mouth around in order to talk, which is hard to do with a huge open mouth.

Yawning is a sign of being tired, but the consequence of yawning being a body language for lying still stands.

Is Blushing A Sign Of A Liar

Is Blushing A Sign Of A Liar

Typically, people blush when they are embarrassed about something. It’s sometimes used to conceal that they are feeling ashamed or embarrassed about what has happened. It’s worth noting if you spot someone blushing a data point. As ever we must read in clusters to give you more of an idea on how to read people please check out our beginner’s guide on body language…….

Is Touching Your Face A Sign Of Lying

Is Touching Your Face A Sign Of Lying

This is a very interesting question. When you touch your face, the skin on your hands is sensitive to the touch and becomes redder. This is called blood flow and is increased when we lie.

The reason for this is that the person lying will feel guilty and they will start to sweat. Sweat produces an itch which results in people touching their face in order to relieve it.

It’s important to note that this sign isn’t 100% accurate as it can be used as a method of deception by those who are good at what they do such as professional poker players, actors, and politicians.

Remember that we must read in clusters of information and that no one body language action can indicate someone is lying to us.

The Eyes

The Eyes

While it is impossible to know for sure if someone is lying, there are some tell-tale signs that will give you a pretty good guess.

Eye movements are one of the easiest ways to notice if someone is lying. If eye movements toward the mouth or forehead increase when they speak, this may show that they are trying too hard to make their story believable. People who lie often look up and to the right more often than people who are being honest which researchers think might be because liars are trying to come up with what they are going to say next. More on eye movement below and why it could be true or false depending on the person.

Noticing Changes In The Eyes

There is no way to tell if someone is lying with their eyes.

The most common statement that people believe is that liars will avoid eye contact. We don’t agree with that statement. A liar will feed you information and watch you like a hawk to see if you have bought into the lie. If anything lairs will not avoid eye contact at all, it’s not in their favor to do so.

All people turn away or lower their gaze when not wishing to confront an object. This appeases a number of emotions, such as sadness, guilt, and disgust. Liars however might show little signs of avoidance, seeing as they know no one expects to be able to see deception in the eyes.

Pupil Dilation

Pupil Dilation

Pupils dilate when people are emotionally aroused, but there is no voluntary pathway that allows anyone the option to make this change by choice.

Pupil dilation is produced by the autonomic nervous system.

While increased pupil dilation is often linked with feeling aroused, it does not tell us what the person is feeling.


It’s normal to cry when stressed, but crying doesn’t always mean a person is sad. Tears happen in moments of distress, sadness, relief, or too much laughing.

If someone is truly crying, their eyebrows should also move or show signs of moisture, too. You should be able to feel the moisture behind the tears, if you don’t, this is another data point worth investigating. noting.

Not all tears are true.

Is blinking a lot a sign of lying? You can baseline someone’s blink rate and notice an increase when they’re under stress. The average blink rate is between eight and twenty times per minute. If you see an increase in blink rate, this is a strong data point and one not to be dismissed.

The blinking reflex, which cannot be suppressed voluntarily, is a basic autonomic behavior that does not usually command attention. We can use it to our advantage when analyzing some body language.

When a blink rate changes, we know something has changed internally. We need to pay extra attention to this to see what is wrong.

Body Language Lying Looking To The Right

Head movements are an important component of facial expressions, they are often unconscious movements that are made without any conscious intent. We make head movements in order to express our thoughts or emotions about what we see or hear in the environment.

If you see the head move to the right or the eyes move down to the right this could indicate an emotional reaction to something that was said or implied.

It’s worth noting the conversation beforehand and digging into the context a little more.

Body Language Lying Looking To The Left

We’ve all seen people on TV, in movies, or in our own lives who seem to tell the truth through their body language. They shake their head left and right to say “No” when they mean “Yes.” The truth is that any head movement does not necessarily indicate lying on its own. If you notice a shift in behavior and it’s within a few minutes of the first time, this could mean deception. However, you need to read body language in clusters of information, so you can get a good interpretation of the situation.

Classic Body Language Signs Of Lying

There are many classic signs of lying include: averted eye contact increased swallowing, fake smile, shallow breathing, and lack of facial expressions. 

Is Touching The Ear A Sign Of Lying

Is Touching The Ear A Sign Of Lying

People use this gesture when they feel they have been caught in a lie or made a bad decision and want to escape from it as quickly as possible. This is known in the body language world as a pacifier or self-soothing behavior. It is worth noting when you see someone touching their ear whilst being questioned.

Remember that there are no absolutes. We should always read in clusters of data and know one piece of body language cannot indicate desperation on its own.

Psychology Body Language Signs Of Lying

Psychology Body Language Signs Of Lying

Understanding the human brain is no easy task. Some basic things like what kinds of food are good for you, how sleep impacts your mental well-being, and how to tell when you’re in danger are some essential information that people need to know.

The primary function of the brain is to send signals from one place to another. The messages are sent through a type of electrical signal called a neuron. Neurons send messages and transmit them from one area in the brain and transmit them to another.

Our brains create a chemical circuit that keeps changing and moving every time we interact with people. Every time we try to figure out what they’re trying to say, we also send them these signals back.

There is no easy way to tell if someone is lying to us. If there were no people, they wouldn’t do it.


Body language experts say that there are certain cues to keep in mind when you are trying to detect lies.

First of all, be aware of their eye contact. If they look away or blink more than usual, they might be lying to you. They may also avert their gaze more than usual, which is another indication that they are not telling the truth.

If they seem to be sweating more than usual or showing signs of anxiety-like rubbing their hands together or fidgeting too much, these could also indicate that they are not being honest with you.

Lastly, if the person feels uncomfortable in some way and is using more hand gestures, for instance, this could mean that something is wrong and it’s time for you to investigate further.

We hope this post has been useful to you and has shown you that detecting lies is hard but not impossible. At the very least, you will have a good understanding of what to look for when a person is trying to deceive you.
