As the saying goes “Actions speak louder than words”. Nonverbal acts have a way of sending a message across, that a verbal act can sometimes lack in. It’s through our body language that we may be transmitting a particular idea or revelation of oneself. The amazing thing about it is, most of the time, we are unaware of such. Think of a weekend poker game with your friends. When you play poker a good amount of reads and planning a certain strategy are directly in relation to the nonverbal communication, in this case, body language, that can be used to one’s advantage in order to win the game. The FBI has been using body language to their advantage for years. They’re playing a game however. As opposed to spotting someone bluffing on the left, or with a strong hand on the right, they are tasked in finding spies. Decoding one’s body language to get the necessary information needed to flush out the moles. In today’s video we dig in on BODY LANGUAGE THE FBI USES TO KNOW IF YOU ARE LYING.


People are often unaware of what their lips look like to other people. This in itself is a major giveaway, as lip compression is often associated with being bothered. The harder you press on these lips, the more it is said that something is really bothering us or there is something negative going on with the person. In fact, rolling lips to point of disappear is a strong sign that someone is lying by omission. Strongly pursing your lips can mean that someone is holding back certain emotions or facts. A study shows that people who are asked sensitive questions often purse their lips as a sort of reflex signaling that they would not rather speak on the certain topic.


Our brains are wired in such a way that our verbal/nonverbal behaviors to naturally matchup. This is the equivalent of asking a friend, a family member, a workmate or a colleague that classic question, “Are you okay?”. We may notice while they may say they’re doing good, their body language is hinting to the contrary. It’s a strong sign that someone is lying, to you and to themselves. Lying can be pointe out by reading specific behavioral patterns that may not be parallel to what they are saying. In short, their nonverbal expressions aren’t matched with the verbal expressions that they are giving off. Like saying thank you, accompanied with a frown, but quickly shifting to an unconvincing smile. Be on that lookout fellow Youtubers.


While in the process of a negotiation, it’s important to note some people who will say “Yes” and few moments later shifting back to a firm “No” or maybe even backtracking as far as saying “I don’t know”. It could be that the party was lying, what some FBI Negotiators do, like former FBI Agent, Chris Voss, is using the “The Rule of Three” to make sure the yes you get, is a resounding solid yes. “The Rule of Three” is getting the opposing party to agree to the same thing, whether it be a statement or a fact, three times in the same conversation. Since it is said to be hard to repeatedly lie and face conviction. There is a tactic to avoid redundancy and giving away your intentions. The first question is usually them giving you a verbal commitment. The second is summarize what they said and word it differently which can result to them saying “Yup, you got it” or “That’s right”. While the third, is usually a “How” or “What” sort of question that will need the opposing party to explain again, solidifying the yes for a third time.


As quoted by Al Pacino in Scarface. “The eyes chico, they never lie”. Looking away, staring, even blinking more than usual can indicate lying. For example, when one looks to the right, it is associated with the right side of the brain that stores memory whether it be auditory or visual. As opposed to the left, which is said to be the creative or imaginary side of the brain. Which means when you ask someone a question, and their eyes look to the left, more often than not that means that person is looking to their creative side to construct something or make something up that wasn’t there previously. Or in short, they’re lying. Research also shows, that for people who are left-handed, the opposite occurs. The right side is the creative one while the left side is for information already there. It’s now always the case however, but can still be used as a powerful tool.


Liars often pause a lot, to construct or make up details to explain something that never really occurred. You ask them a question, and then after a pause they begin to explain. Now there’s a fine line between pausing to think and remember and pausing to think and come up with something so you don’t get spotted. Paying attention to these pauses is key as the person may be making up facts as they are speaking along the way. It is also known that people who pause in between speaking, usually are thinking hard and can show brief gaps in between conversations that is consistent with people who lie. However, the context of the question should be taken into account. When we ask a question such as “Do you remember what you did two weeks ago?” It would obviously take some time for the person to respond as their brain goes through a process of remembering that said information. As opposed to “Two weeks ago, do you remember meeting this certain individual?” the specificity of the question should incur and immediate response.


Anxiety plays a role when it comes to detecting liars. On a physiological standpoint, questions can often cause anxiety and as a result, dryness or discomfort can be apparent in the mouth and throat. When a person clears his throat, or does an obvious swallow, experts believe that he is lying due to the uneasiness brought upon by the situation. The anxiety also comes from the person lying and not wanting to be figured out. The Cognitive load also plays a factor, as it causes the brain to concentrate on a particular issue or memory. A Cognitive Overload happens when the person spends too much external stimuli on the working memory. Liars do what they can to sound convincing. This added emotional stress triggers a fight-orflight response which can result in the moisture in the throat, redirected to the skin which results in one needing to clear his throat that is often seen as a sigh of deception.


Strange isn’t it? That a person standing completely still can be a sign of someone not telling the truth. But consider this, when a person decides to lie in order to avoid a hasty situation, they may stand still for a few moments as they figure out how to make their detection as plausible as possible. Due to tension and nervousness, they may keep their movements to a minimum. As opposed to a normal situation, people are usually relaxed and appear to be more fluid with their body. While liars on the other hand, become stiff or rigid as a result of the discomfort of withdrawing certain information. These signs are often telling that a person is not being truthful.


Keep it simple. Answer the question, Yes or No? If they fail to answer the simple Yes or No question, then that presents a considerable red flag. If someone gives an unclear answer, ask them again. If it still persists, chances are they are lying. The fact that they couldn’t give a straight up answer, or answered in a way that avoided the question in itself, then it likely that the person opted for the route of deception. With a yes or no question, if someone starts their answer with a “Well…” it usually results in an answer that the person asking wasn’t expecting.


Thumbs are a part of the body that is usually correlated with how we really feel or how well we relate or agree with a statement. It is said that lowering the thumbs or even hiding the thumbs is usually a sign of a lack of commitment or communicates insecurities. It tells us there is an issue at hand as while someone may be emphatic with what he is saying, the thumbs usually point up or show themselves as way of the body being parallel to that emphasis. The opposite shows a contradiction, and that the person is potentially telling you a lie or not giving it all to you straight.
