Pretty much everyone is going to lie about something at least once in their life. What people do not understand is that their lies will eventually come back to haunt them. There is a good chance that they’re going to be called out on their lies at some point or another. There are numerous signs that can potentially tell you that someone is not telling the truth. By taking the time to analyze a person’s behavior, there is a pretty good chance that you’ll be able to determine whether or not they’re nervous or anxious. They could fiddle with their hands or play with their hair. This could a sign that they’re being deceptive about something.

What should you look for when attempting to determine whether or not someone is being deceptive? You’ll discover the top 10 signs of deception in the article below.

Look At Their Eyes

As the old saying goes, the eyes are the doorways to a person’s soul. By taking the time to analyze a person’s eyes, there is a good chance that you’ll be able to learn a great deal about them. If you look into someone’s eyes, you can determine how they feel about you. You can also figure out precisely how they’re feeling at the given time. You’ll know whether or not they’re feeling upbeat and happy or down and depressed. At the same time, there is a pretty good chance that you can use the participant’s eyes to determine whether or not they’re being deceptive. Deceptive individuals tend to exhibit similar eye behaviors.

Liars tend to have a difficult time making and maintaining eye contact. Good liars will know how to control their eyes to avoid looking guilty, but most people will not. Speak with the individual in question and see how their eyes react. Do they immediately look downward? Do they look away? Do their pupils widen? These are all things that point to someone telling you a lie. If they look away or their pupils become noticeably wider, there is a good chance that they’re telling a lie.

The Mean Length Of Utterance

By listening to someone’s words, there is a good chance that you’ll be able to detect deception pretty easily. Sometimes, their sentences matter far more than the words themselves. Take the time to listen to the person’s sentences and sentence structures. On average, the mass majority of people speak in sentences consisting of ten to fifteen words. When they’re lying about something, this changes significantly. Liars will normally drag out their sentences to a great degree.

When someone is anxious or nervous, they’ll usually lengthen their sentences. Other people may actually make the sentences a little bit shorter. Listen closely to the participant to determine whether or not their sentence structure has been lengthened or shortened. If you notice a change, there is a possibility that the participant is lying to you.

Twitching

Have you ever experienced twitching when you’ve gotten nervous? Have you noticed that your arm twitches or shakes when you’ve been caught in a lie? This has something to do with the nervous system and it can prove to be very effective for helping you determine whether or not something is being untruthful. When speaking to someone that you believe may be lying about something, you should carefully monitor their behavior and their body language.

Do you notice any uncontrollable or unforced movement? Does their eye twitch? Does their hand shake? If the person is attempting to hide a lie, there is a good chance that their body will tell on them. They’ll become very nervous and their body will exhibit the signs of nervousness. Twitching or shaking could very well be a sign that the person in question is telling you a big lie.

Changing The Subject

Have you ever spoken with someone, who consistently tries to change the subject? Have you tried to chat with your girlfriend or boyfriend about their weekend? Have you noticed that they glance over the topic and try to shift to something new as quickly as possible? While this isn’t always a surefire way to detect a lie, it could prove to be a very important sign. When someone becomes concerned that they’re going to get trapped in a lie, they’ll do everything humanly possible to avoid the subject all together.

Bring up the subject once again and see what happens. Does the person once again try to shift the blame to something else? If the person seems constantly on edge and always eager to avoid the subject in question, there is a real chance that they’re hiding something from you.

Stuttering

Unfortunately, some people are born with a stutter. Each and every time they open their mouth, some people will have a difficult time trying to finish a sentence, due to a stutter. Of course, it is absolutely pertinent to realize that stuttering problems are actually very rare. Only a small percentage of the population will have to deal with such problems in their lifetime. However, it is also important that stuttering can be circumstantial. For instance, some people will actually stutter their words when they experience a tumultuous situation. Some people stutter, because they’ve encountered a situation that makes them anxious.

If you chat with someone that usually never stutters and you begin to notice a stutter, there is a possibility that they’re nervous about something. Does the person stutter over their words when you mention a specific subject or ask a certain question? This could a real sign that they’re worried and are trying to hide something from you. Pay close attention to a stutter to determine whether or not the person in question is lying to you.

Giggling

There is often a misconception that giggling is a sign that someone is happy and upbeat. This is true sometimes, but not always. In fact, giggling can sometimes mean something entirely different. Depending on the situation at hand, there is a chance that the giggle could mean that the person is nervous at the given time. It is sometimes referred to as a nervous laugh or an anxious giggle. Pay close attention to laughs or giggles that happen when they shouldn’t. If you’re chatting about a very serious topic and the participant lets out a giggle, they’re probably anxious about something.

When a giggle happens at the wrong time, the laugher is probably worried or hiding something. Pay close attention to this and use the giggle to help you determine what is really going on at the given time.

Constant Movement

During the pretesting interview, the examiner will go over the process utilized for the lie detector exam. At this time, the examiner will explain the important of remaining calm and keeping body movements to a minimum. If at any time, the individual becomes fidgety, the examiner will know that they are trying to alter the results of the test. While there is truly no real way to determine if the individual is being deception, this behavior is a good indication of deception. The key to achieving accurate results will depend on the individual remaining calm and move as little as possible.

Since you will be connected to several medical devices, just the slightest movement will throw off the test. An examiner will observe your behavior throughout the test and if you are too fidgety, it will be noted and considered deception.

Sweating Profusely

Just the thought of knowing your past activities are going to be exposed can be nerve-wrecking. Everyone has skeletons in their closet and has done things that they are not proud of. While the lie detector test is designed to bright these to light, it may not be focused on those particular elements of your past. Just the mere thought of these activities coming out can cause one to perspire profusely. With this said, if you attempt to cover up your past indiscretions during the lie detector test, it is possible that your body will work overtime, by producing a lot of sweat.

The examiner will not only observe your behavior throughout the test, but also will note any changes in your physical appearance. If you begin to sweat, the examiner will think you are trying to be deception. The sweat beads will appear on your upper lip, forehead and continue to spread throughout your body. It will be entirely impossible to keep your body from sweating, because it is an autonomic response.

Speaking Too Low Or Too High

Most experienced examiners that have conducted innumerable lie detector tests throughout their career will have seen it all. What this means is they will have seen people do some crazy things in an attempt to cover up their deceptions. One particular thing comes to mind is speaking to loudly or too low. During the pretest interview, the examiner will explain to you that your normal voice should be utilized, when answering the “yes” and “no” questions. You should always avoid speaking out of the norm, because this could alter the test results.

It is true that some people have tried to alter their results, by answering the questions in a very loud or low tone. The examiner will know if you are being deceptive, so do not even attempt to replicate this behavior.

Forcing A Smile

Another telltale sign of deception is a forced smile. While the lie detector machine is not capable of measuring facial expressions, the examiner will always be on the lookout for them. If you force a smile, when the examiner asks a specific question, he/she may consider this a sign of deception. Just try to maintain your composure and never force a smile, because it is not necessary to answer the question properly.
