Tongue Jutting

The FiveThirtyEight blog noted the frequency with which McCain stuck out his tongue during last Friday's debate. The behavior is known as "tongue jutting." It's a well-known "tell" that professional interrogators and poker players look for. According to retired FBI agent Joe Navarro, this is what it means:

Tongue-jutting behavior is a gesture used by people who think they have gotten away with something or are “caught” doing something... This behavior has several meanings – depending on specific situations – but is usually associated with one of these: I got caught (taking candy from a drawer), gleeful excitement (look at what I just did, Mom), I got away with something (and I didn’t get caught), I did something foolish, or I am naughty.

I'll add that tongue jutting (or tongue protrusion) is also a behavior often seen in the animal world. Reptologists have developed the "tongue flick attack score" which is "a common method for quantifying predatory behavior in squamate reptiles." A higher score (i.e. more tongue flicks) indicates a greater predatory response.

Tongue protrusion is also a form of sociosexual behavior that has been observed in nocturnal Owl Monkeys. It is part of a range of mating behavior that includes lip-smacking, squinting, partner-marking, and urine-drinking.

So the question is, was McCain's tongue jutting more reptilian or primate? i.e. was it more predatory in nature, or sociosexual? I'll leave that to you readers to decide.

Dammit outeast, you beat me to the partner-marking joke!

trueconservative, I agree that's very likely. However, did you see the Colbert Report last night? When they showed all of the instances of licking, one right after the other, it was hilarious!

Not until November 5th.

It's interesting that McCain displayed all this nervous behavior, while Obama was described as, "cool as a cucumber."
