11 signs someone is lying to your face

A majority of the people you talk to on a daily basis are big fat liars.

A 2002 study conducted by University of Massachusetts Amherst psychologist Robert S. Feldman found that 60% of people lied during a 10-minute conversation, and they told an average of two to three lies in that time.

Luckily, fibs are fairly easy to spot - you just have to know the signs.

Dr. Lillian Glass, a behavioral analyst and body language expert who has worked with the FBI on unmasking signals of deception, says when trying to figure out if someone is lying, you first need to understand how the person normally acts. Then you'll want to pay careful attention to their facial expressions, body language, and speech patterns, she writes in her book "The Body Language of Liars."
