We were all getting wierded out by B*sh's rapid-fire blinking last night , and we were trying to figure out what it meant psychologically. I mentioned that I instinctively don't trust people who are blinking all the time, so this morning I ran a quick google query to see if my suspicions were based on a common understanding of body language. It turns out I'm on the right track, blinking is a huge indicator of deception.

The eyes communicate more that any other part of the human anatomy. Staring or gazing at others can create pressure and tension in the room. Gangs have fought over the way someone looked at them. Researcher suggests that individuals who can routinely out gaze another develop a sense of control and power over others not so inclined. Maintained eye contact can show if a person is trustworthy, sincere or caring.
Shifty eyes, too much blinking can suggest deception. People with eye movements that are relaxed and comfortable yet attentive to the person they are conversing with are seen as more sincere and honest.
Eyebrow muscle draws the eyebrows down and toward the center of the face if someone is annoyed. If
someone is empathetic and caring during dialogue the eyebrows will not show the annoyed facial grimace.
Bodily cues are the most reliable of all nonverbal signals of deception. This is because a person generally has less conscious control over these than other signals. (Springer, 1996; Ekman & Friesen, 1974). Hand-to-face gestures and shrugs are strong markers of deception. Playing with or touching things nearby during conversations has been found to be associated with deception (Cody & O'Hair, 1983). Deceivers also are likely to have increased illustrator activity--quick and animated use of hands/arms during speech.
Vocal cues can predict deception. More and lengthier pauses during conversation; a lot of such sounds as "uh," "um," word repetitions; intruding sounds not part of the actual speech, less lengthy answers or explanations where they would be expected to be.
