Wouldn’t it be nice to know how to tell if someone is lying?

Did you know that just 54 percent of lies can be accurately spotted? Extroverts also tell more lies than introverts and at least 82 percent of lies go undetected.

To identify a fib, you first have to have a baseline for how someone acts when they're being honest, says Traci Brown, body language expert and author of How to Detect Lies, Fraud and Identity Theft: Field Guide. For example, watch how someone responds to a basic question such as, Where are you from? Where do their eyes go? How does their voice sound?

Lying and deception are common human behaviors. Until relatively recently, there has been little actual research into just how often people lie. Some surveys have suggested that as many as 96 percent of people admit to lying at least sometimes. One national study of 1,000 U.S. adults found that 60 percent of respondents claimed that they did not lie at all. Instead, the researchers found that about half of all lies were told by just 5 percent of all the subjects.

People lie for many reasons. Sometimes people lie to save face and other times they lie for personal gain. Spotting a lie becomes particularly vital when you want to avoid being conned or scammed. Although there's no surefire way to do it, there are many signs to watch out for to determine if someone's being untruthful.

Telling when someone is lying is all about sub-communication and body language. Especially the eyes. There are things known as access ques - what this means is that you can tell when someone is lying, by the direction they look at, as they speak. Watch the facial expressions. When people tell the truth, they are at ease. When they are lying they go back in their mind to make up situations.
