Summary – Chapter 16

We began this chapter knowing full well that lie detection through nonverbal means was difficult at best. However, we did cover a huge amount of clues that can help us by raising suspicion and provide us with leads to delve further. We began the chapter by looking at the reasons for lying which includes hiding feelings, preferences and attitudes. We found that lying is used to reduce disagreements and hurt feelings and is a useful skill in impression management. We listed the nine reasons people lie which are to avoid punishment, to gain access to a reward, to protect another person or one’s self from being punished, to win admiration of others, to avoid awkward social situations, to avoid embarrassment, to maintain privacy and to gain at the expense of others.

We found that by grilling someone for the truth it is often enough to cause someone to feel stress thereby creating the behaviour instead of uncovering it. Contrary to popular belief we discussed that eye contact can often increase during lying rather than decrease due to “duping delight” where a person receives a charge from pulling one over on someone else. We learned that lying is hard work so should expect that when someone is caught with difficult questions that they should exhibit more nonverbal leakage and might even ‘appear’ to be thinking harder. Nervousness and guilt was touched on which showed that at times liars can give themselves up through a higher pitch, faster and louder speech, speech errors or stuttering, blushing, an increase in blink rate, fidgeting, dilation of the pupils or sweating, but that these cues only reveal liars that actually feel guilt, and not all do. Liars can also tend to “freeze up” and reduce movement and we related it back to professional poker players. Next we looked at how liars remain uncommitted to their lies, and thereby use less exuberant gesturing, and can stop or reduce touching when they lie.

Next we looked at the “truth bias” which shows that an average of sixty-seven percent accuracy is found when detecting the truth, whereas forty-four percent is found while detecting deception because people expect to be told the truth so have adapted to detect it. We found in this chapter that truth tellers (and liars) are sometimes less cooperative, but not always, and looked at the FACT or the facial action coding system as another way to detect lies. “Microexpressions” were defined as facial expressions that flash across the face in 1/25 to 1/5 of a second and can betray liars because they are difficult to consciously control and appear more honest. We discussed that while lying requires fabrication, telling the truth can be just as difficult since details must be recalled from memory. Police officers, we found, are fairly good at detecting lies, but this is in spite of what they are taught rather than because of it. Lying language in children was discussed and then we classified the major gestures that are usually associated with lying, but that aren’t always actually indicative of it. Our aim in doing so was to avoid doing them so we can avoid being mislabeled as untruthful by others. These commonly associated gestures include touching the face and ears, scratching the neck, pulling at the collar, touching the eyes, mouth, or nose and closed body language. We also examined eye patterns in lying, verbal and paraverbal cues and nervous body language as they relate to lying. We discovered that machines such as the fMRI, thermal scanners, eye trackers, pupillometers and stress sniffers had a much greater success rate when compared to people, but were also expensive and impractical.

We finished up the chapter by examining true success which is achieved by the experts; the CIA who scores seventy-three percent, sheriffs sixty-seven percent, psychologist sixty-eight percent and the secret service who scored sixty-four percent as well as techniques for actually detecting lies by comparing the baseline of a person as they shift from comfort to discomfort based on questioning or other stimulus.

So Which People Are Good At Detecting Lies?

At this point in the chapter it might seem out of place to admit that some individuals can actually detect lies better than chance, but this is true, and has been backed up empirically through research. Studies have shown that while the rest of the world is limited to fifty percent, or the same accuracy as that which would occur by chance, the CIA (central intelligence agency) scores seventy-three percent, sheriffs sixty-seven percent, psychologist sixty-eight percent whereas the secret service scores sixty-four percent.

So why do the experts have an advantage over the layman? Well, part of the explanation lies in experience. The group of psychologist was chosen due to their special interest in lying and lie detection, not to mention their willingness to participate in a two day seminar covering various topics related to lying and lie detection. Each group including the psychologists, the CIA, and the secret service all have an interest in lie detection coupled with the training to back it up. Experts are drawing on information from many facets about a person, including their paraverbal and nonverbal language as well as other cues as we have covered which is unlike regular lay-people who have little if any experience in analyzing people, let alone the ability to repeatedly test their skills. Because lie detection and reading people is a huge part of their occupations, they get a lot of practice and feedback.

Personality characteristics might also play into the ability to detect lies. For example, empathy, sensitivity to social cues, and conscientiousness can all help in reading people more accurate because it allows a person to put themselves in someone else’s shoes. Experts are also more aware of the truth bias, which we covered earlier, and so can properly adjust for this phenomenon. It is important to conclude on these matters that the accuracy, while impressive in relation to ordinary people, is still far from perfect. While the experts are far from perfect, they do give us some hope that lie detection is more than a chance operation. No doubt, by reading this chapter alone, you will be able to make huge strides in reading others, perhaps not pegging every liar dead on the spot, but the cues in this chapter will help you at least identified those who are worthy of a second look.

The Truth Bias

A review of the literature on lying and truth telling shows us that an average sixty-seven percent accuracy is found when detecting the truth, whereas forty-four percent is found while detecting deception. In other words, people’s accuracy at detecting truths is usually higher than their accuracy at detecting lies! This is what is called the truth bias. Some possible explanations for the truth bias stem from the fact that in everyday encounters we usually deal with honest people. While lying is pervasive, it doesn’t happen nearly as often as does lying. Thus, we expect people to be telling the truth and are therefore better at detecting it.

Another possible reason for our inherent truth bias is because it would be detrimental to act suspiciously while speaking with others just in case they were telling the truth. If our default was to label other people as deceptive, we’d be constantly interrupting others to clarify statements, or our suspicion would have our minds busy fact checking at a later time. Our conversations would be littered with statements such as ‘That can’t be true’ or ‘Really, I can’t see that’ or ‘I’ll believe that when I see it’ which sometimes it is, but usually not. This would be time consuming and counterproductive given the nature of real to life situations, that is that people normally tell the truth. Our social rules also do not permit us to act suspiciously and if we did so would alienate others and prevent us from formulating alliances or friendships. In fact, ignoring the faults of others is the primary reason we allow ourselves to associate with anyone at all. Those with a memory for detail find it hard to ‘let things go’ or ‘ignore subtle unimportant flaws’ which can be detrimental for relationships. The truth bias tells us that letting little ‘white lies’ go, is an integral part of human nature, perhaps even necessary.

Other Complex Seating Arrangements

It is possible to create a highly influential seating arrangement when we wish to influence a particularly important, but as yet undecided individual. The first person or the main presenter (Pr) should sit head-on with the “object” in the face-to-face competitive position (Ob). This competitive position aligns the “object” with the person he most expects to object with. Next, we add an affiliate (Af) to the objects left or right, that is, at the casual corner position to act as a friend, or to their side in the cooperative position (Co). The subconscious effect can be powerful if the positions are matched with the outlooks they should hold. That is, the cooperative position should play the advocate against the competitive position in cooperation with the object, except (of course) showing a bias towards agreement with the competitive position.

The affiliate can also “bait” the competitive position and control the conversation by giving up relevant points without sounding pushy. This person can demonstrate ‘the other side of the coin’ and work through the dialogue saving the object from having to voice negative positions himself. This saves him from going through counterproductive mental reasoning that can prove a damaging exercise. Powerful negotiators can use the affiliate to blow the argument out of proportion thereby forcing the object to side with the competitor and bridge the original argument. Obviously this isn’t a simple strategy and requires some advanced preparation, but when it is an important matter it is justified, not to mention fun!

Affect Or Emotional Displays

Affect displays is subset of nonverbal language that reveal our emotional state. For example, if we are happy we can show enthusiasm, or if we are telling a sad story, we correspondingly show somber. Affect display include facial expressions such as smiling, laughing, crying or frowning.

Awareness of various kinds of affect and how it is used in speech will provide vital clues about the speaker and his or her intent. Affect displays occur in synchrony and within the rhythm of speech. They emphases certain words or phrases and are an integral part of speech and thought. They can tell us about the expressiveness of a person and also what they find most important in their speech by which words they choose to emphasize. Posture can also signal emotion as can a variety of other gestures.

Affect is also different from culture to culture. For example, Russians tend to smile much less than Americans and therefore an American might come across as overly friendly to a Russian. Conversely Russians might come across as disinterested or aloof to Americans because they smile less frequently. In reality, both cultures are neither aloof nor overtly content, they simply appear to be so as they are viewed through a complimentary cultural norm bias. There is no right or wrong way to display affect, which is to say that no culture is better or worse because it smiles, frowns or cries less or more than another during expression.

A Caution About Biases During The Baselining Process

Self hugging can mean that he's shy or just a place to put his hands.

We also have inherent biases which we must be careful of when try to read other people. Our dislike of certain people could influence us to read their language in a less then favourable light. Knowing that this bias is an inherent possibility, can at least protect us in terms of accuracy, and set up conditions that avoid possibly destructive fallout. This is only one factor to be careful of while reading people as it relates to baselining. Reading lying body language, by example, is very difficult and not having anything to compare it to essentially makes it impossible.

Poker is an excellent game that hones our nonverbal analysis of people, and the best modern day poker players will, with the advent and popularity of televised poker, review thousands of hours of video on their opponents. While some of the time they are watching to pick up on specific “tells” they are also developing their baseline. By doing so, even prior to meeting them they can have some players pegged. They can then use their baseline to determine actions, especially novel ones, that are out of the ordinary. If you’ve ever walked into a new poker group, you understand exactly what I mean. You might know some of the people, but usually there are others that you haven’t yet met add to this a novel context and you’ve got your work cut out for you. Since you don’t know the other player’s baselines you naturally end up being cautious and if you know poker cautious being “tight” can be just as bad as being “loose”. Over time you build their character and they start to “make sense”. In everyday life we call this process “getting to know someone” but in the body language world, we are formulating their baseline. Baselining is really about having the ability to compare someone to themselves.

Nose crinkle can mean a negative thought as in a game of poker.  I've, however, see this gesture feigned (and yes I lost the hand over this bluff).

The ‘nose crinkle’ can mean a negative thought as in getting a bad card in a game of poker. I’ve, however, seen this gesture feigned (and yes I lost the hand over this well executed bluff).

Let’s look at arm crossing or even touching the nose. Everyone thinks that arm crossing means that someone is closed and unreceptive. This might be true for some people some of the time, but to others, it means that they are comfortable. If I were to cross my arms, just now, would it mean I was closed? No, it wouldn’t, it simply means that my arms are crossed. The same goes for nose touching as an indication of lying or deception. Some people touch their nose at the end of every sentence – it’s their idiosyncrasy. Does this mean that every word that comes from their mouth is a lie? It could be, but it is not likely. Once we’ve caught someone in a lie we can backtrack and look at the clues that preceded the lie and those that followed the lie to pick up on cues that might have given him away. Poker players do just this, although for them it’s simpler since there really are only two possible scenarios, he is bluffing, or he really has a strong hand. Video even provides professional poker players with one hundred percent of the information at hand, there are no secrets and so baselining can happen very quickly. In real life, things are not as obvious and there is a lot of gray in between the truth and a lie so it takes a lot more effort do develop baselines, however with practice even novel situations with unknown people will begin to appear similar to other past experiences and people. So baselining provides us with information that we can use in the future when lying or any other emotional behaviour is suspected, where we can draw from our database of “tells” and make educated guesses about the truthfulness, or emotional state of our subject or subjects.

Introduction – Chapter 2

Mastery of anything begins by first learning the basics, and body language is no different. A solid structure can not be built without first forming and pouring a solid foundation. This chapter is aimed at accomplishing just that, as we tackle the basic, but very important rules of body language. It might seem as though reading body language is as easy and simple as just reading cues and postures, but it isn’t. At times it can be downright confusing, although the aim here is to simplify the language by breaking it apart then reassembling it, but not until the cues are first put through a strong filter. One of the filters we use is based on the five cardinal rules of body language which says that we need to use the rule of four. This rule tells us that we need at least four related cues to form a conclusion. We also need the cues to ‘jive’ called congruence, they must be taken in context, fit along some baseline of behaviour and finally must not be filter through a bias, meaning that they must be true rather than created fictitiously for an ulterior purpose. We will examine the five cardinal rules in detail in the pages to follow.

Just like regular spoken language or written language, silent speech or nonverbal communication also has what is called flow. Body language has rhythm, syntax and all the other nuances associated with general communication and ignoring this flow is akin to throwing away valuable information. We will also see that body language is much more reliable than spoken words because people generally pay little attention to it, and because of this, people will monitor it less readily allowing it to appear naturally and untainted. We will see that when body language and spoken language contradict one another, we should rely more heavily on what is happening non-verbally.

We will also cover the differences in body language reading ability between men and women, how age can influences reading, which may or may not be surprising and how leaders or alpha members of our society call the shots even when it comes to body language. We will touch a bit on good posture, how best to use touching, and how body language relieves pent up energy and displaces it. Finally we will touch briefly on the meaning of fashion and how it plays into nonverbal communication.
