Let there be Lightman

Dear reader,

part of doing hypnosis and especially hypnotherapy, is to observe the client. Something very important is to look for incongruence. That's when the body contradicts the spoken word. You may have experienced this in your daily life before. Usually, I guess, we get a strange feeling. "Something" isn't quite right. It's when I'm with a friend and ask him if he wants to come over to my flat. His mouth says "yes", but he's shaking his head "no". So which is it now?

A certain Albert Mehrabian did an experiment and found out that if someone is incongruent, we break down his non-verbals and what he says. According to Mehrabian, about 55% is body language as such, 38% is speech (how fast it's said and that kind of thing) and only 7% is what's actually said. This means that when we're in doubt and someone is incongruent, we tend to trust the non-verbals and body language more than the actual talk. Mehrabian found that out in 1971. People still like to quote that study. But they misquote it badly actually. They leave out that his study was for incongruence and say that we trust the words only 7% all the time. That's wrong! I guess this misquoting and misinterpretation happens when people take out of the study what they like and other people quote the people quoting that study. I believe that rather few people actually read the original story, but (mis)quote it all over the internet. That's so sad.

Another person worth mentioning when the talk is about body language, incongruence and lies is Paul Ekman. He's the lead expert on deception and lies. According to Ekman, there are 7 basic emotions, which are the same with every human around the globe. They are:


The pictures above show Tim Roth and the pictures have been made as part of the tv series "Lie To Me", where he plays the deception expert Dr. Cal Lightman. He's modelled after Paul Ekman, who also worked as consultant for the show. So "Lie To Me" isn't just any wanna-be-science show. Much of the science on that show is actually true and really works. FOX, which by now has cancelled LTM in the middle of season 3, has since taken away Paul Ekman's blog where he explains aspects of his science on almost all episodes. There are only a few exceptions, for episodes in which nothing special regarding his science came up. You can still read it here now: http://www.paulekman.com/lie-to-me/

Personally I have so far only read "Why Kids Lie" by Paul Ekman. It's a nice read. Especially I found it interesting that the book was a family project really. Paul started of, then his son took over to write from a child's point of view, including some advice for what parents should be doing or can do. And then his wife, who worked as an attorney, wrote the last chapters.

What fascinates me about body language and lie detection is the aspect of so called micro-expressions. That's very quick expressions you make showing your real emotion and then hide it with another expression. Paul Ekman is better at explaining this, so I'll let him talk here: http://www.youtube.com/watch?v=EXm6YbXxSYk
I think it's helpful to know the science of facial expression. Probably we don't need to bring it to perfection to see micro-expressions. Knowing the science of facial expressions as such, does help though. Lightman makes that point at the end of the second episode of season 1. In the pilot episode they get a new staff member, Ria Torres, who is a natural. She can see and correctly read facial expressions, including micro-expressions, without formal training. Lightman seems a bit annoyed by her and teases her quite a bit in that second episode. There are scenes when Torres says nothing, but Lightman reads her face and she shows negative emotions. She pays him back in the final scene when she reads his face. However he shrugs it off. When she calls him a liar, he simply tells her to get used to it. Seeing things is one thing. He tells her that without the science, she's unable to see the whole picture and people get hurt. I have to agree with him, that with the science of it in mind, we get a deeper understanding.

Paul Ekman also created programs to train yourself in recognising facial expressions as well as micro-expressions. If you're interested in those kind of things, check out his website.

One thing about detecting lies: It's a widely accepted myth that liars would break eye contact with you. The idea being that the liar can't stand looking you into the eye for a longer time. Probably for fear of you seeing he's lying. Actually eye contact says nothing about whether someone lies or tells the truth. As Lightman and his colleagues repeatedly state: The important thing is to have a base line. Some sort of reference point which tells you what the person is like in a fairly relaxed state. If you don't know what a person is like in a relatively relaxed state, you're unable to tell anything about him. If he has a twitching hand, even when you're talking small talk, it's likely to be a normal behaviour for him and has nothing to do with nervousness or impatience or anything like that. If that person has calm hands in a small talk situation and the hand twitches when the talk gets to more serious matters, it's likely that something is going on now. But a twitching hand as such means nothing. Similarly, if someone crosses his arms and legs, it doesn't necessarily mean disagreement. Notice what the person is like when you think he's fairly relaxed and telling the truth. Once the person does something else and breaks this behaviour in some general way, these may be signs of holding back informations and/or telling lies.

The british magician, or self-proclaimed "psychological illusionist" Derren Brown makes those points of how to tell a lie in his book "Tricks of the Mind" as well. He also explains a trick/experiment you can do with anybody willing to take part. If you go for the three main sensory systems we have visual, auditory and kinaesthetic. Ask a person five or so questions for each of those sensory systems. They should tell you the truth. It can be really simple questions. Notice how they move their eyes. If you think you know their pattern, you can ask them to tell you a number of things (say five again) and one should be a lie. The lie is when they don't keep their usual pattern of "truth telling", as you established before. Derren Brown makes it seemingly even more interesting and mysterious as he tells the person only to think of the answers and not say them aloud. Here's a video of Derren Brown doing this trick with car salesmen: http://www.youtube.com/watch?v=Gi2cvop3vbM
Go with Derren and make your choice about which facts are lies. Again: don't just go for eye contact or breaking eye contact. Eye contact or not are no indicators for lies or truths!

The blog title today comes from... you guessed it, Cal Lightman. In episode 2, season 3, we see him having problems starting to write his new book. Instead he procrastinates big time with making beans on toast at 4 a.m. and even sets off the fire alarm when he burns the toast. He's distracted with a video he watched on his laptop. So his daughter Emily comes down to see what's going on. She suggests writing just any sentence. Lightman rejects her first line, so he types into the laptop: "Let there be Lightman." and presents it with his arms stretched in a "ta-da!" kind of fashion. Emily tells him to hire a ghost writer and decides to go to bed again. I love the scenes with the two of them. Sometimes Emily seems much more grown-up than her dad. He often does what he feels like doing, which isn't always appropriate and sometimes even dangerous. See for yourself.

Well, I think that's it for now. My take on body language, truth, lies and those kind of things.

I'll keep you posted! Stay tuned!
