 Is her face giving it away?

You may think a smile can easily disguise your true feelings, but the expressions that flash across a liar’s face will give away what she’s really thinking—whether she knows it or not. Experts advise paying close attention to hard-to-hide micro-expressions; these clues are often so difficult to detect that even trained experts have trouble discerning them. But you may be able to spot a liar by the red color on her cheeks since anxiety can cause people to blush. Other ways to tell if someone is lying? Flared nostrils, lip nibbling, deep breathing, and rapid blinking, which hint that the brain is working overtime. These are the worst lies you can tell in a relationship.

Does the body language follow the story?

It’s more important to examine a person’s entire demeanor, as there’s no one feature that’s apt to give away how to spot a liar. Honesty is characterized by features that are in sync with one another—so besides posture, note the fit between face, body, voice, and speech. Like an animal avoiding detection, a liar may pull his arms and legs inward or keep his movements to a minimum—anything to appear smaller. Liars often shove their hands behind their back because those fidgety digits might give them away.

How is the person smiling?

How to tell if someone is lying could come down to something as simple as a smile. A bright grin can sometimes mask a person’s true feelings. Pay close attention to how a person smiles as well as other facial movements. You may be able to detect the emotions he or she is trying to hide—such as fear, anger, and disgust. A true smile will incorporate both a person’s lips and eyes. Watch out for these little lies people are guilty of telling every day.

How is the person speaking?

What is the person saying?

These are common lies people tell their doctors—and why you need to stop.
