Look at this Bush photo, then read this article about "Micro-Expressions"

[Stephanie]

It's a long article from the New Yorker by Malcolm Gladwell, who wrote The Tipping Point. I posted this earlier as the definitive Bush photo, but I didn't explain why. His truth is revealed in this photo, IMO. He is scared shitless. The article explains the science of micro-expressions, as used in law enforcement. We are biologically incapable of hiding our true emotions. They will flash across the face, however fleeting. This photographer caught one. Bush in the headlights, frozen with fear.

ANNALS OF PSYCHOLOGY

Can you read people's thoughts
just by looking at them?

Ekman calls that kind of fleeting look a "microexpression," and one cannot understand why John Yarbrough did what he did on that night in South Central without also understanding the particular role and significance of microexpressions. Many facial expressions can be made voluntarily. If I' m trying to look stern as I give you a tongue-lashing, I'll have no difficulty doing so, and you' ll have no difficulty interpreting my glare. But our faces are also governed by a separate, involuntary system. We know this because stroke victims who suffer damage to what is known as the pyramidal neural system will laugh at a joke, but they cannot smile if you ask them to. At the same time, patients with damage to another part of the brain have the opposite problem. They can smile on demand, but if you tell them a joke they can't laugh. Similarly, few of us can voluntarily do A.U. one, the sadness sign. (A notable exception, Ekman points out, is Woody Allen, who uses his frontalis, pars medialis, to create his trademark look of comic distress.) Yet we raise our inner eyebrows all the time, without thinking, when we are unhappy. Watch a baby just as he or she starts to cry, and you'll often see the frontalis, pars medialis, shoot up, as if it were on a string.

Perhaps the most famous involuntary expression is what Ekman has dubbed the Duchenne smile, in honor of the nineteenth-century French neurologist Guillaume Duchenne, who first attempted to document the workings of the muscles of the face with the camera. If I ask you to smile, you' ll flex your zygomatic major. By contrast, if you smile spontaneously, in the presence of genuine emotion, you' ll not only flex your zygomatic but also tighten the orbicularis oculi, pars orbitalis, which is the muscle that encircles the eye. It is almost impossible to tighten the orbicularis oculi, pars lateralis, on demand, and it is equally difficult to stop it from tightening when we smile at something genuinely pleasurable. This kind of smile "does not obey the will," Duchenne wrote. "Its absence unmasks the false friend." When we experience a basic emotion, a corresponding message is automatically sent to the muscles of the face. That message may linger on the face for just a fraction of a second, or be detectable only if you attached electrical sensors to the face, but It's always there. Silvan Tomkins once began a lecture by bellowing, "The face is like the penis!" and this is what he meant--that the face has, to a large extent, a mind of its own. This doesn't mean we have no control over our faces. We can use our voluntary muscular system to try to suppress those involuntary responses. But, often, some little part of that suppressed emotion--the sense that I' m really unhappy, even though I deny it--leaks out. Our voluntary expressive system is the way we intentionally signal our emotions. But our involuntary expressive system is in many ways even more important: it is the way we have been equipped by evolution to signal our authentic feelings.

"You must have had the experience where somebody comments on your expression and you didn't know you were making it,"Ekman says. "Somebody tells you, "What are you getting upset about?' "Why are you smirking?' You can hear your voice, but you can't see your face. If we knew what was on our face, we would be better at concealing it. But that wouldn't necessarily be a good thing. Imagine if there were a switch that all of us had, to turn off the expressions on our face at will. If babies had that switch, we wouldn't know what they were feeling. They' d be in trouble. You could make an argument, if you wanted to, that the system evolved so that parents would be able to take care of kids. Or imagine if you were married to someone with a switch? It would be impossible. I don't think mating and infatuation and friendships and closeness would occur if our faces didn't work that way."

Ekman slipped a tape taken from the O.J. Simpson trial into the VCR. It was of Kato Kaelin, Simpson's shaggy-haired house guest, being examined by Marcia Clark, one of the prosecutors in the case. Kaelin sits in the witness box, with his trademark vacant look. Clark asks a hostile question. Kaelin leans forward and answers softly. "Did you see that?" Ekman asked me. I saw nothing, just Kato being Kato-- harmless and passive. Ekman stopped the tape, rewound it, and played it back in slow motion. On the screen, Kaelin moved forward to answer the question, and in that fraction of a second his face was utterly transformed. His nose wrinkled, as he flexed his levator labii superioris, alaeque nasi. His teeth were bared, his brows lowered. "It was almost totally A.U. nine," Ekman said. "It's disgust, with anger there as well, and the clue to that is that when your eyebrows go down, typically your eyes are not as open as they are here. The raised upper eyelid is a component of anger, not disgust. It's very quick." Ekman stopped the tape and played it again, peering at the screen. "You know, he looks like a snarling dog."

Ekman said that there was nothing magical about his ability to pick up an emotion that fleeting. It was simply a matter of practice. "I could show you forty examples, and you could pick it up. I have a training tape, and people love it. They start it, and they can't see any of these expressions. Thirty-five minutes later, they can see them all. What that says is that this is an accessible skill."
