1. Specific Expressions.

 Specific expressions are facial expressions that just on a person’s face for a flash of moment. It can reveal his / her emotions and the real truth behind the lie. There are many signals of emotions of those people who are lying that I think they will be helpful for you. For example, when people are lying, the eyebrows will be drawn upwards to their middle forehead that will cause short lines across the forehead’s skin.

2. Base On Specific Actions. 

When lying, people usually touch their nose more; this may be because of the effect of adrenaline to the capillaries in people’s nose that can cause their itching nose. Besides, a liar tends to cover his/her mouth with hands or to place the hands near his/her mouth. Or, if his/her mouth appears tense and his/her lips are pursed, then he is distress.

3. Base On Eye Movements.

If you want to know when a man or woman is remembering some events or something, you can base on his / her eye movements. In this case, his / her eyes move to the left (if he/ she is right-handed). The vice versa is true to the left-handed. Apart from this signal, when a person is lying, he also tends to blink faster. This condition appears in men much more than women.

4..Do Not Just Base On Eye Contact. 

As usual, people often think that a liar tends to avoid contacting their eye with others when lying. However, this is not totally true. Some people might deliberately make their eye become more sincere by practicing. In some cases, people usually enhance the eye contact level to prove for the investigator that they are not lying. So, using eye contact as a sole indicator of truthfulness is not always true.

Or, you can watch their eyelids to explore whether they are telling the truth or not. These eyelids tend to closer longer than normal if a person sees or hears something that he / she does not agree with. Yet, it is necessary for you to compare how that person blinks between normal condition (non-stressful) and the opposite one. One more signal of lying is that the hands or fingers tend to go to the eyes when a person is blocking out the truth.

In general, you should be careful when assessing someone’s lie because you need to combine many other factors to give a final conclusion.

1. Base On Sweating. 

There is a fact that if people sweat more, then this is a strong proof of lying. Yet, it is not always a reliable lying indicator. Many people tend to sweat more whenever they feel nervousness and shyness. You also should combine other signals like trembling or blushing.

2. Base On Nodding. 

If a person is nodding in opposition to things they are saying. This is a fierce evidence of “incongruence”. As proven, a truthful person will nod and answer nearly concurrently while the liar is opposite to.

4. Base On Throat Of That Person.

 When lying, a person might lubricate the throat by clearing their throat or swallowing. If they lie, their body will produce a substance called adrenaline that makes the saliva pumping. Whilst their saliva is emerging, the subject will gulpe it down. In the opposite case, the subject may clear their throat.

5. Base On Breathing. 

Of course, this is one of the most popular signals as well as lie detection techniques when determining whether that person is telling the truth or not. When lying, the mouth tends to be dry, and the breath is short; thus, the heart will beat more quickly, the lungs need more air.

6. Base On Body Parts. 

There are many lie detection techniques that you can learn; however, you should not omit the behaviors of that person’s hands, arms movements, or even his legs movements. In addition, folded arms, interlocked legs can be a sign of hesitating to give away information.

7. Base On Smile.

A smile 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.

2. Base On The Exaggerated Details.

3. Base On The Impulsive Emotional Responses.

You also can base on the timing and duration of the conversation to give the solution if that person is lying. If he does something like expressing the expectation to be asked or rattling off something, then he might lie you.

4. Ask The Person Repeat The Story Over Again.

If you are not sure about the story they are telling, ask them to tell again the story several times. In fact, it is difficult for everybody to keep track repeat something that is not truthful. If in the re-telling process, he seems to be inconsistent, then he is lying.

5. Base On The Person’s Sayings.

Liars tend to avoid exclusionary words like “nor,” “but,”, “except,” and “whereas,” because they have trouble with complex thought processes. Also, they are less likely to use the words “I,” “me,” and “mine.” In their attempts to distance themselves psychologically from their tall tales, liars tend to communicate using fewer personal pronouns.

6. Use Silence. 

It is very hard for a liar to fill the silence made by you. If you keep patient and remain the silence, a lot of deceitful people will keep talking to avoid suffering from that silence, embellishing and possibly slipping up in the process, without even being asked anything!

7. Establish A Baseline. 

A baseline is how someone behaves when he or she is not lying. By this way, you can define whether the actions they are acting are different from their normal actions or not. For someone who you have already known, you can check the lie and uncover the truth by asking some questions relating to things or what you already know the answer before. 

8. Follow Through. 

If possible, check out the truth behind what that person is telling you. A liar who is skilled may give some reason why you shoul not talk to those people who know the facts or the truth. So, you can check with the person you have been warned against. Anything factual that could be checked should be checked.
