Is it possible to know if someone is lying to you? Sadly, not really. You can’t always tell the difference between an honest answer and a liar with lots of practice. Listen to your gut and look for patterns.
My mom used to say she could look into my eyes and tell if I was lying. I don't know what she was looking for, but some people spot lies by watching for changes in a person's demeanor. Things like eye movement, fidgeting, and acting nervous are supposed to be dead giveaways. It's not that simple.
Every liar has a tell. Once you spot it, you'll know their pattern and the lies will be easily spotted. Here are some patterns:
Omission
Some people lie by omission. They'll leave out important details. People who lie by omission will do it over and over.
You: "Who'd you go to lunch with?"
Liar: "Bob"
Later you find out that he also went with Raquel.
You again: "You lied! You didn't tell me that Raquel was there, too!"
Liar: "I didn’t lie; I just didn’t tell you."
Um...ok.
Adding details
These liars will introduce characters that don't exist to cover something up. They also might add details to the story.
You: "Who'd you go to lunch with?"
Liar: "I went to lunch with Raquel, Bob, Bill, and Steve. Bob told us about his fishing trip."
Later you find out that he had lunch with only Raquel.
The exaggerator
This type of liar will tell tales that are based on fact but stretch the truth a lot. In the movie Grease, you'll see Danny do lots of this when he's bragging about his "Summer Nights" with Sandy. We find out later that Danny is an exaggerator. Yes, he and Sandy did spend the summer together but let's just say that it didn't go exactly as he described.
The key to an exaggerator is that their story usually can't be verified. In the movie, he thought Sandy returned to Australia and he'd never see her again. Unverifiable claims like Danny's usually can only be spotted by using the "Oh really" test. But do this internally. Don't call them out.
You: "Have you ever been to Los Angeles?"
Liar: "Totally. I had the best time hanging out with the Kardashians!"
You (to yourself): "Really? Really? You hung out with the Kardashians?"
Here are your options when dealing with an exaggerator.
- Let it go.
- Avoid them.
- Change the conversation.
- Call them out. I don't recommend this.
- Ask follow-up questions (my preferred approach).
You: "Oh wow! So fun! What is Kim like?"
Exaggerators can be a lot but just accept them. If you can't deal, they aren't friendship material anyway.
Projection
This type of liar will blame you for something that they're doing. Remember that cheaters think everyone cheats and liars think everyone lies. Use this to your advantage. If someone is overly suspicious of you for no reason, they're telling you not to trust them.
Projection liar: "I saw you flirting with Raquel!"
Later you find out she was flirting with Steve.
Questioning the source
Clever liars almost always question the source of the information first. They might even do this in an intimidating manner. On the other hand, an honest person will look confused as to why the question is being asked.
Check this out:
You: "Did you eat my cupcake?"
Liar: "Who told you that!?!"
Honest Person: "We have cupcakes? Anyway, I've been gone all day."
You can't always go by that, though. If the liar knows the question is coming, they will be ready with a straight denial. A firm denial doesn’t mean anything but a lack of denial, combined with questioning the source, is almost always a lie.
Trust
If any of these describes you, please stop. You should never trust anyone that lies to you and don't expect trust if you're a liar.
