Study Finds the Easiest Way to Spot a Liar

It turns out the way to tell if someone is lying isn't what a person says - it's in how they look when they're saying it.

A research study from the University of British Columbia found that four muscles in the face can help you figure out if you're getting the truth or not.

Researchers studied the facial expressions of 52 people, half genuine, half lying. They found... that certain facial muscles actually leak signs of whether or not a person is being honest.

When the people were telling the truth, two areas in their face gave them away: the corrugator supercilii, in between the eyes, and the depressor angulioris, in the lower face.

When someone tells the truth, you'll see the inner eyebrows together and pointing upwards. The muscles around the mouth pull the lip corners down, like a frown. Then, the chin muscles contract and show dimples.

With liars, there was more smirking, as well as movement in the forehead that made them look surprised. So when someone is lying, you'll see a little smirk or half smile.

Another sign: They can't use the muscles that draw the inner eyebrows together and upwards. Instead, they're only able to raise their eyebrows and forehead, so they looked surprised.
