Lie to Me Season 1 Episode 1 – Pilot

Leakage & Emblematic Slips

Dr. Lightman showed the law enforcement class how micro expressions helped him find out where this nasty, Nazi-sympathetic, orange-suited, prisoner had planted a bomb.

While the prisoner kept his mouth shut he couldn’t prevent a micro facial expression of delight slipping out when he learned from Lightman that the FBI was wasting time, searching the wrong church. When Lightman told him he had figured out that the FBI should look elsewhere, the suspect broke his silence: “You don’t know what you are talking about”. The leakage this time wasn’t in the face, but a gesture – a one-sided shoulder shrug that contradicted his words. Catching that contradiction reassured Lightman he was going in the right direction.

In these few seconds “Lie To Me” illustrated two of the most valuable sources for clues to deceit. I call them leakage because they occur despite a person’s intention not to reveal the information that leaks out. Typically people who leak don’t get wet; they don’t know that the information has leaked.

Micro facial expressions are involuntary; the person showing a micro expression is unaware of doing it. Most people don’t see micro expressions unless they have obtained training.

The prisoner also showed what we call an emblematic slip, the equivalent in gesture of a slip of the tongue. I use the term ‘emblem’ for any gesture that has a precise meaning known to all members of a cultural group – such as the A-OK emblem in the U.S. (Watch out; emblems are specific to each culture. Someone will slug you if make the A-OK emblem in Sicily where it refers to what is considered a perverse sexual practice!)

Typically emblems are made in what I call the ‘presentation position’, very noticeable because they are performed right in front of the person making it and very pronounced, with a beat. Emblematic slips are made outside of the presentation position, and usually they are only a fragment of the full emblem, performed without a beat. That is what the prisoner did, he showed just a fragment of the shrug that means ‘I don’t know’ or ‘I can’t do it’. The person showing the emblematic slip knows what he or she is thinking but doesn’t know it has leaked out.

Looking While Lying

Lightman is right that people often look away when they are trying to remember something, but you might have missed how Lightman could be so certain that it was proof the boy was lying.

People look away when they are thinking carefully and considering each word before it is spoken, not just when they are making it up. The boy knew his teacher was murdered and he is the prime suspect. He would be wise to be cautious in giving his answers. But Lightman noted that the boy wasn’t cautious, didn’t look away, when he answered other questions. It is this difference that made the difference, which justified Lightman’s interpretation. Lightman correctly said that breaking eye contact doesn’t prove lying; that is a myth.

Eyebrows Give You Away

Oblique eyebrows are a very reliable sign of sadness. Very few people can make this movement voluntarily, so it is virtually never faked. And few people can prevent it if they feel sad.

Yes or No?

Lightman commented on the emblematic slip — shaking the head ‘yes’ very slightly when saying ‘no.’

Note that it was slight, not pronounced. I have seen this in my research subjects when they lie and in real life criminal and celebrity lies many times.

Naturals & Wizards

In inviting Torres the TSA officer to join the Lightman group, Foster called her a natural, one of those people who without training can spot a liar.

We call them the wizards. They are very rare but they do exist. Dr. O’Sullivan is writing a book about them. The Paul Ekman Group does train TSA surveillance people in what is called the SPOT program (Screening Passengers by Observational Techniques), as does the Lightman group.

Distancing Language

Distancing language is a sign that there is some strong emotion about the topic that the person using that language is trying to step away from. As in “I did not have sex with that woman…”

Going Backwards

Foster’s request that the congressman retell his account of how he spent the night backwards is a standard technique used by many interrogators. Liars prepare a frontwards story and have a much harder time telling the story backwards.

Shame

While there is no facial expression unique to signaling shame, often people who are feeling this emotion try to hide part of their face.

The Polygraph

Foster accurately describes the problem with the polygraph – it only tells you he was feeling guilt not what he was feeling guilt about.

Fear Kicks In

Lightman is using information about skin temperature and emotion that Robert Levenson, a professor of psychology at UC Berkeley, and I discovered. The hands get cold during fear, because the blood flows away from the hands to the large muscles of the legs to prepare for flight. Just the reverse happens with anger, when blood flows to the hands and arms to prepare for fighting, raising the temperature of the hands. It is not that we have to either flee or fight, but evolution has prepared us to do what most people who survived over the history of our species did do.

Don’t Know the Answer?

When people know the answer to the question they are asked, often the brows are raised; when they don’t know the answer, the brows may be lowered. A tip off that Lightman makes good use of. So can adolescents when their parents ask them, “What time did you come in last night?”
