Most times, there are quite a few ways to tell if someone is lying to you; some signs are obvious while others are more discreet. Someone is probably lying if:


- A change in demeanor or talk. When a conversation turns to a point where the other person is lying, they may begin speaking faster or start moving their hands a lot. On the other hand, they may become more quiet and stop looking you in the eye. [1]


- They avoid using the word "I" when speaking about themselves. For instance, if your boyfriend is lying to you, he may something like "This guy here stayed in all night'. Avoiding the word helps them to distance themselves from the lie. [1]


- They keep repeating the same thing over and over again. Repeating allows the liar time to come up with something believable to say. It also means they are trying to convince both you and themselves that the lie is true. [2]


-They provide you with too much information. Many liars believe that providing a blow-by-blow account of something that they seem more believable. They think you will think their openness equals truthfulness; don't fall for it! [2]


- They keep covering their mouths. In their subconscious, the liar believes covering their mouth prevents them from lying. [2]

Often when people lie their bodies give them away. In order to successfully know when someone is lying to you, you need to master the art of human lie detection. We can spot a lie with only 54% accuracy. Human lie detectors read facial expressions, body language, voice tone and statement analysis to detect deception. Research has shown that learning human lie detection techniques can help you improve your lie spotting ability up to 90%. [1]

 

 

Human lie detection is like a humanized polygraph. The science trains the naked eye to see guilt, nerves and hidden emotions in a similar way that a polygraph measures heart rate, respiration rate and sweat.

 

The first step to human lie detection is baselining

 

A baseline is how someone acts when they are under normal, non-threatening conditions. It is how someone looks when they are telling the truth. When you want to better read a person’s emotions or spot when they lie, you will need to find their baseline, or notice how they look, sound, act and behave when they are telling the truth. To do this you want to discuss neutral topics.

 

Step two happens when you suddenly notice a change in baseline. This is called a hot spot area. Like a polygraph picks up spikes in heart rate or sweat, you can pick up on sudden ticks or a jiggling foot that was not there before. Specifically a hot spot area is when you notice someone differs from their baseline. Some cues that indicate a person is lying include; 

 

Opposite Nodding: This happens with nodding. For example, someone will lie and say “yes” but without realizing it, shake their head no.


One Sided Shoulder Shrug:It has been discovered that people have the tendency to slightly lift their shoulder when they lie. It is almost as if they are shrugging because they don’t believe what they are saying. [2]

There are a few signs that indicate that someone is lying to you. First, pay attention to the person's head movements [1]. They may inadvertently jerk or tilt their head, right before they answer a question. Also, as a way of "convincing" you of their story, the liar may give you too many details (including information that you don't need to know) or may simply repeat the same information over and over again. Also, watch the person's eyes. If they blink a lot or attempt not to meet  your eyes, they may be lying.

 

A few other things to watch out for are throat clearing, swallowing, and leaning backward [2]. However, keep in mind that there is no sure-fire way to determine that someone is lying. If you notice several of the indicators above, it could be a possibility, however.
