In this article, we'll look at how to tell if someone is lying. Certain behaviors and characteristics become apparent when a person lies, whether it's a little white lie or a significant one.

There will always be people who, after learning about these signs, start feigning confidence and acting in ways designed to avoid being found out. However, it takes a great deal of practice and mental control to stay aware of everything from our gestures and body language to how we explain things, and so on. Even then, the person is very likely to let something slip that gives them away.

Knowing when someone is lying can be crucial in many situations: if your pet has gone missing and you ask your neighbor whether they’ve seen it, in a crime-related situation, or in cases involving infidelity, abuse, and more.

How to Tell If Someone Is Lying: Look for These Signs!

It’s important not to make a habit of analyzing everyone around us, especially our partner. Some lies are harmless. For example, your partner might lie about where they were because they have a surprise planned for your birthday.

If you ask your boyfriend whether he likes that dress and he says yes even though he doesn’t, because he knows you always get upset when he says no—or if you ask whether he thinks someone is attractive and then get angry too, there’s no point in it. So use these tips only when it’s truly necessary and when doing so can help you or someone else.

Here are some important things to keep in mind when spotting lies and liars. These 5 points can help you tell if someone is lying.

A telltale smirk

Certain facial expressions can reveal whether someone is suppressing an emotion, lying, or has just told a falsehood.

The most common is a smile at the end of a lie—but not just any smile. It’s that tiny, almost unnoticeable smirk, the one we make when we’ve gotten away with something. You’ll recognize it because it’s an expression someone tries to suppress, but it comes out spontaneously.

Eye Contact

Watching someone’s eye contact is one of the best-known techniques. It’s something our mothers told us, just as their mothers told them, and so on.

The fact that this is so well known works against it, since it gives liars an advantage: they can learn how to maintain eye contact while lying and even get good at it.

As I mentioned earlier, there will always be a fleeting sign that gives away a liar, so maintain strong eye contact. If you suspect the person in front of you is lying, make your gaze more insistent, so they know you’re suspicious. Ask questions, even if they’re about the same thing, and pay attention to when they look away. That may help you find out whether someone is lying.

Note: Keep in mind that there are other reasons someone might look away, such as feeling intimidated, feeling shy around someone they like, being insecure, or feeling small in someone’s presence.

Body Language

Studies show that body language accounts for most of our communication: 30% of what we communicate is what we say, and 70% is what we show.

That’s why it’s important to pay attention to gestures, hands, posture, and how the other person behaves.

– Open palms

When someone is being honest, they show the palms of their hands. When someone is lying, they tend to keep their palms hidden.

– Covering the mouth

When someone is lying, they may cover their mouth with their hands from time to time, or touch their nose frequently.

– Crossed arms

Rather than indicating a lie, this posture suggests denial, insecurity, annoyance, and arrogance. If someone says, “I’m listening to you,” “I understand,” “I’m fine with that,” or “No problem,” but has their arms crossed and their legs creating a barrier between you, their words and feelings are not in sync. It may also mean they’re not receptive to you, either because they find the conversation uncomfortable or boring.

– The direction their body is facing

I remember a teacher once telling us to stop being so eager to run out of class, since it was almost time to leave. We all looked at her, wondering what we’d done wrong. She then told us that when someone feels uncomfortable or anxious to leave, their legs and feet will point toward the exit.

We all looked at each other, and sure enough, our feet were pointing toward the door. In fact, mine were already out from under the desk, angled as if I were about to run out.

So if someone is with you but their body is constantly facing the door, they’re probably bored, annoyed, or have somewhere else to be.

Well-crafted stories

People who lie rehearse their lies carefully. For example, if he already knows his girlfriend will ask him:

“Why didn’t you come yesterday?” “Why didn’t you reply to my message?” or “Where were you yesterday?”

He’ll probably come up with an excuse before seeing her and make up his story from beginning to end.

But what happens when we turn the story around? A person who is lying memorizes the details in chronological order, so try to dig further into their story by asking: “What did you say you did before that?”, “Where did you say you were?”, or “Don’t you always carry your charger with you?”

Dodging the Question

When someone answers with lies, they dodge the question, use longer pauses, or say things like “umm” or “uhh.” It’s worth noting that people also use these expressions when they’re thinking. If you ask, “Did you do your homework on Monday?” or “Have you been sick since the weekend?”, the person needs to remember, which will also take time. However, if you ask, “Do you like how this dress looks on me?” and he answers, “Umm, uhh… yes.”

People who are lying often respond with other questions, for example:

• Excuse me, Don Chuy, my dog went missing yesterday. Have you seen him?
• What, have I seen him? He went missing? Who? Me?
• Yes, you. Have you seen my dog today, Pancho? You know him very well. Did he come to the store?
• To the store? Who? Your dog?
• Yes, Pancho. Did he come by here today?
• Today?

They keep going around in circles without giving a clear answer.

Well, these are a few tips to help you stand up for the truth and expose a liar right in front of you.
