Lying is a common part of human interaction. We all lie, sometimes for good reasons, sometimes for bad. But how can you tell if someone is lying to you? There are a few things you can look for, both verbal and nonverbal.
When someone is lying, they may try to avoid eye contact. They may also fidget or move around a lot. They may also have difficulty speaking smoothly, or they may use a lot of filler words, such as "um," "ah," and "like."
In the following section, we will take a closer look at some of the specific verbal and nonverbal cues that can indicate someone is lying.
How to Tell if Someone Is Lying
Look for these signs of deception:
- Lack of eye contact
- Fidgeting or moving around
- Difficulty speaking smoothly
- Use of filler words
- Contradictions in their story
- Vague or evasive answers
- Sudden changes in tone or pitch
- Sweating or blushing
Keep in mind that these are just general guidelines. Not everyone who exhibits these signs is necessarily lying. However, if you notice several of these cues, it may be a sign that the person is not being truthful.
Lack of eye contact
One of the most common signs that someone is lying is a lack of eye contact. When people are telling the truth, they tend to look the other person in the eye. This is because eye contact is a sign of honesty and sincerity. When someone is lying, they may try to avoid eye contact because they feel guilty or ashamed. They may also be afraid that their eyes will give them away.
However, it is important to note that not everyone who avoids eye contact is lying. Some people simply have a hard time making eye contact, even when they are being truthful. Additionally, some cultures view direct eye contact as disrespectful. Therefore, it is important to consider the person's cultural background before making a judgment about whether or not they are lying.
If you are unsure whether or not someone is lying, there are a few other things you can look for. For example, liars may also fidget or move around a lot. They may also have difficulty speaking smoothly, or they may use a lot of filler words, such as "um," "ah," and "like."
If you notice several of these cues, it may be a sign that the person is not being truthful. However, it is important to remember that these are just general guidelines. Not everyone who exhibits these signs is necessarily lying.
If you are concerned that someone is lying to you, the best thing to do is to ask them directly. Be polite but firm, and let them know that you are not going to be fooled. If they are lying, they will likely become defensive or try to change the subject. If they are telling the truth, they will be able to answer your questions honestly and directly.
Fidgeting or moving around
Another common sign that someone is lying is fidgeting or moving around excessively. When people are nervous or anxious, they may try to relieve their tension by moving their body. This can include fidgeting with their hands or feet, tapping their fingers, or pacing back and forth.
- Biting nails or cuticles
This is a common sign of anxiety or nervousness. If someone is doing this while they are talking to you, it may be a sign that they are not being truthful.
- Playing with their hair or clothes
This is another sign of nervousness or anxiety. If someone is constantly twirling their hair or picking at their clothes, it may be a sign that they are trying to hide something.
- Pacing back and forth

It is important to note that not everyone who fidgets or moves around is lying. Some people simply have a nervous habit of fidgeting. However, if you notice that someone is fidgeting or moving around excessively, it may be a sign that they are not being truthful.
Difficulty speaking smoothly
When people are lying, they may have difficulty speaking smoothly. This is because they are trying to keep track of their story and make sure that they are not contradicting themselves. As a result, they may hesitate or stumble over their words. They may also speak in a monotone voice or use a lot of filler words, such as "um," "ah," and "like."
- Hesitation or stumbling over words

- Changing the subject
If someone suddenly changes the subject, it may be a sign that they are trying to avoid answering a question or that they are lying. Pay attention to the context of the conversation and see if the subject change makes sense.
It is important to note that not everyone who has difficulty speaking smoothly is lying. Some people simply have a speech impediment or a nervous habit of stuttering. However, if you notice that someone is having difficulty speaking smoothly, especially if they are also exhibiting other signs of deception, it may be a sign that they are not being truthful.
Use of filler words
Filler words, such as "um," "ah," and "like," are often used to stall for time or avoid answering a question. When people are lying, they may use filler words more frequently than usual in an attempt to buy themselves time to think of a lie or to avoid saying something that will incriminate them.
In addition to using filler words more frequently, liars may also use them in a strategic way. For example, they may use filler words to pause before answering a question, or they may use them to interrupt the flow of the conversation. This can make it difficult for the listener to follow what the liar is saying and to detect inconsistencies in their story.
Here are some examples of how liars might use filler words:
- "Um, I was at the store, and I saw, like, this really cool shirt."
- "Ah, I don't know. I guess I just, like, forgot."
- "Well, you see, I was, um, running late, and I didn't have time to finish my homework."
It is important to note that not everyone who uses filler words is lying. Some people simply have a habit of using filler words when they speak.

One of the most common signs that someone is lying is contradictions in their story. When people are telling the truth, their story will usually be consistent and coherent. However, when people are lying, they may forget what they said earlier and contradict themselves. This can be a sign that they are trying to cover up their lie or that they are simply not being truthful.
- Forgetting key details
If someone is lying, they may forget key details about their story. This is because they are trying to keep track of their lie and make sure that they are not contradicting themselves. As a result, they may forget important details or they may get their facts mixed up.
- Changing their story
If someone is lying, they may change their story over time. This is because they are trying to cover up their lie or to make it more believable. As a result, their story may become more elaborate and less credible.
- Contradicting themselves
If someone is lying, they may contradict themselves directly. This is because they are trying to keep track of their lie and make sure that they are not saying anything that will incriminate them. As a result, they may say one thing and then say something else that contradicts it.
- Being evasive
If someone is lying, they may be evasive when answering questions. They may try to avoid answering the question directly or they may give vague or incomplete answers. This is because they are trying to avoid saying something that will incriminate them.
It is important to note that not everyone who contradicts themselves is lying. Sometimes, people simply make mistakes or they may forget things. However, if you notice that someone is contradicting themselves frequently, especially if they are also exhibiting other signs of deception, it may be a sign that they are not being truthful.
Vague or evasive answers
When people are lying, they may give vague or evasive answers to questions. This is because they are trying to avoid saying something that will incriminate them or that will reveal their lie. They may also be trying to buy themselves time to think of a lie or to come up with a good explanation for their behavior.
Here are some examples of vague or evasive answers that liars might give:
- "I don't remember."
- "I'm not sure."
- "It's complicated."
- "I can't talk about that."
- "I don't want to answer that question."
Liars may also use vague or evasive language to try to avoid giving a direct answer to a question. For example, they may use words like "maybe," "possibly," or "kind of" to make their answer less definitive.
Here are some examples of vague or evasive language that liars might use:
- "I might have been there."
- "It's possible that I did it."
- "I kind of remember seeing them."
- "I'm not really sure what happened."
It is important to note that not everyone who gives vague or evasive answers is lying. Sometimes, people simply do not know the answer to a question or they may not want to share personal information. However, if you notice that someone is giving vague or evasive answers to multiple questions, especially if they are also exhibiting other signs of deception, it may be a sign that they are not being truthful.

Additionally, some people may experience changes in their voice due to medical conditions or vocal strain. However, if you notice that someone is experiencing sudden changes in their tone or pitch of voice, especially if they are also exhibiting other signs of deception, it may be a sign that they are not being truthful.
