How to tell if someone's lying to you

Did you know that you hear between 10 and 200 lies a day? Spotting a liar can be difficult, especially when you're dealing with a pro, but one language expert says there are tell-tale signs in the way people talk that could reveal when they're not being truthful.

Noah Zandan, a science communicator, says the key to uncovering a lie is "linguistic text analysis," and it's based on sentence structure.

According to his TED talk, there are three specific things to look out for:

1) Liars are more negative when they lie, possibly because they feel guilty.

2) They also distance themselves from the lie by speaking in third person or talking about other people. TED video points to Lance Armstrong. In 2005, he denied using performance-enhancing drugs and used hypothetical situations about someone else. But when he finally told the truth in 2013, he got a lot more personal.

3) Liars also use very simple terms when explaining a story. It's easier to keep track of a lie when the details are basic and not so complex.

Liars also tend embellish to make the story sound more convincing.

Mark Twain once said, "If you tell the truth, you don't have to remember anything."

If you find yourself still struggling to spot a lie, you might not be completely hopeless.

Smartphone app developers are working on facial recognition technology that could detect a user's emotions and tell when they're lying.

But a wise word to liars: If you can't tell the truth, it's best to just not say anything at all.
