How to tell if someone is lying

In our daily lives, we interact with different people with various intentions, but sometimes we cannot tell if they are telling the truth or just manipulating the situation. We often ask ourselves, “how to tell if someone is lying?” The fact is that despite many claimed indicators such as body language, facial expressions, and tone of voice that could give away a liar, none of them are scientifically reliable. But that doesn't mean they're completely useless! 

The ultimate way to detect deception is not by focusing on any particular actions, but rather on the difference between those actions and the person's natural behavior — the way they'd behave if they were being honest. Keep reading for a rundown of subtle cues that the words coming out of someone's mouth might not be totally truthful, or that they're on the edge of their seat about what they're telling you.

How to tell if someone is lying

It's not always easy to tell when someone is lying. But with a little bit of knowledge and intuition, you can start to recognize the tell-tale signs of deception. Here are ten signs to look out for:

1. Their Story Changes

One surefire sign that someone is lying is that their story changes, whether it be small details or major plot points. It's almost as if their lies have a life of their own and they can't keep them all straight in their head. Inconsistencies in their narrative become increasingly evident the more they try to maintain their falsehood.

However, it's not always easy to spot a liar, as they may be incredibly skilled at fabricating tales on the spot. But the more you probe and ask for specifics, the more likely it is that their inconsistencies will surface. Liars tend to lack coherence, and their explanations are often riddled with loopholes. 

2. They Avoid Eye Contact

It is not uncommon for individuals to naturally avert their gaze every once in a while, but prolonged avoidance of eye contact is an indicator of deceit. Truthful people usually establish a sense of trust through direct eye contact, and when someone is lying, they avoid it as it creates discomfort. 

If they look down or around, it may be a sign that they are trying to create a distance from the person they are deceiving. Avoidance of eye contact could also signal feelings of guilt and shame associated with the lie. A liar may be fearful of getting caught, and as such, will do anything to keep the fac?ade going.

3. They Fidget

It's common knowledge that liars often engage in deceptive behavior to cover up the truth. One telltale sign of lying is fidgeting, as it often signals discomfort, nervousness, or lack of confidence. 

When someone is lying, they may try to distract you by tapping their feet, playing with their hair, or even moving their hands erratically. These nonverbal signs may seem innocuous, but they can reveal a lot about someone's inner state. Liars feel a sense of discomfort and anxiety when they know they are deceiving someone. Fidgeting is a natural way for them to release some of this nervous energy.

4. They Use Defensive Language

When someone is lying, they often use defensive language to protect themselves from being caught out. It's their way of deflecting attention away from the truth and trying to shift the focus onto something else. Defensive language can take many different forms, but some of the most common signs to watch out for include using vague or non-specific statements, redirecting the conversation, or trying to place the blame on someone else.

One common tactic used by liars is to make themselves sound like the victim, rather than the perpetrator. They may say things like "I can't believe you're accusing me of this" or "Why are you being so unfair?" This type of language is designed to make the accuser feel guilty or embarrassed for questioning the liar's story.

5. They Repeat Phrases

Prolific liars tend to repeat certain phrases or words over and over again, as if trying to hammer their story home. This tactic can be an attempt to make the story seem more believable, but it can also be a way to buy time while the liar tries to think up new details. For example, if you ask someone about their whereabouts last night and they keep repeating "I was at home, I swear", it could be an indication that they're trying to hide something.

6. They Hesitate

When someone hesitates before answering a sensitive question, it could mean that they're lying or that they're simply taking the time to think about their response. However, if the hesitation is particularly pronounced or out of character, it's worth taking note. 

Perhaps the person is trying to come up with a convincing answer that will cover up the truth. Or maybe they're nervous about giving an answer that conflicts with what they've said before. Either way, hesitation is a red flag that shouldn't be ignored.

7. They Speak Too Confidently

It's often said that the key to successful lying is confidence, and there's some truth to that. Liars will often try to bolster their story by speaking with an excessive amount of confidence. They may seem almost too sure of themselves as if they're trying to convince you that what they're saying is true by sheer force of will.   

However, there's a fine line between confidence and arrogance, and it's not hard to spot when someone is overcompensating. Liars will often repeat themselves, trying to drill their false narrative into your mind. They may use phrases like "believe me" or "trust me" repeatedly as if to preempt any doubts you might have.

8. They’re Vague

A liar will intentionally avoid providing too much information in their responses as they try to avoid being caught in their lies. Their aim is to keep things simple and obscure so that they don't slip up or reveal inconsistencies.  

This is a clear indication that they are not confident in their ability to keep up their fac?ade and their answers will lack depth and specificity. A liar may also try to use filler words such as “um”, “like” and “you know” to buy time while they come up with a response.

9. They Smile Too Much

It's not unusual for a liar to try to cover up their dishonesty with an overly-friendly attitude. A fake smile or a nervous laugh might seem harmless, but it's actually a red flag that something's not quite right. In fact, it's one of the most common signs of a liar.  

Of course, it's important to keep in mind that not everyone who smiles too much is lying. Some people just have a more positive outlook on life, or they might be trying to ease tension in an awkward situation. But if you're trying to determine whether or not someone is telling the truth, it's worth paying attention to how often they're grinning from ear to ear. If it seems excessive, it might be time to dig a little deeper.

10. They Deflect

How to tell if someone is lying

One of the most effective tools in a liar's arsenal is deflection. When a liar feels backed into a corner, they'll try to redirect suspicion onto someone else, often by accusing the person they’re lying to of being paranoid or distrusting. This is done in an effort to make themselves appear innocent. 

For example, imagine that you suspect your partner of cheating on you. You confront them, and they respond by saying something like, "You're always so paranoid and jealous. You need to trust me more." By deflecting the blame back onto you, they are trying to shift the focus away from their own dishonest behavior.

Recognizing these signs can help you learn how to tell if someone is lying, and avoid falling for their deceit. But always trust your instincts and use common sense, and remember that even the best liars can be caught in their lies eventually.

Being able to tell when someone is lying is a valuable skill to have in many aspects of life. Whether you are trying to determine if someone is cheating on you, or if they are being dishonest in business, there are certain cues that you can look out for that will indicate if someone is lying.

1. Pay Attention to Their Body Language

2. Listen to Their Tone of Voice

Another trick regarding how to tell if someone is lying is by listening to their tone of voice. When people lie, they often speak in a higher-pitched, shaky, or faltering voice. They may also hesitate, stammer, or speak in an overly elaborate or rehearsed way. Pay close attention to any inconsistencies in their voice or language.

3. Look out for Micro-expressions

Micro-expressions are brief facial expressions that appear for a split second and are often difficult to see with the naked eye. However, when captured and slowed down, these micro-expressions can reveal the liar's true emotions. A slight frown, pursed lips, or raised eyebrows can be enough to detect if someone is lying or not.

4. Watch for Emotional Signs

Emotional responses are often the easiest way to spot a liar. Liars may display an overly exaggerated emotional response to divert your attention away from their lies. Alternatively, they may seem to be emotionless when discussing something that would typically elicit an emotional response.

5. Ask Open-ended Questions

Liars are more likely to slip up when answering open-ended questions than those with limited response. Avoid basic questions that can be answered with a simple yes or no and instead opt for ones that require an elaborate response. This way, you'll get more information and detect any inconsistencies.

6. Trust Your Instincts

At the end of the day, our gut instincts are often our best guide. If something feels off or suspicious, don't be afraid to question it. If you're still not sure if someone is lying, try taking a break and coming back to the conversation later with fresh eyes.
