Body Language a Sign of Truthfulness

A politician's body language is often just as important as the words.

Aug. 28, 2008 — -- As more politicians get ready to hit the stage during the presidential nominating conventions, they should be cautious about what they say -- and what they don't. Body language can speak volumes.

Whether it's blinking too frequently (a sign of discomfort) or gesturing frenetically (a sign of dishonesty), body language analysts say that perfecting the text of a speech is only one of many hurdles good speakers must master before approaching the microphone.

One man who has become somewhat of a public speaking guru, according to Greg Hartley, a former Army interrogator and author of "I Can Read You Like a Book," is former President Clinton, who spoke Wednesday evening at the Democratic National Convention.

"Bill is a pro," Hartley said. "He uses his face and hands to draw people in to what he's saying."

Hartley, who watched the former president and the Democratic vice presidential nominee Joe Biden speak, said that Biden's authenticity was shown through something as seemingly insignificant as his lips.

"Biden was licking his lips a tremendous amount -- it shows genuine emotion," Hartley said. "It's the human side of him and the animal side of him.

"When you see someone purse their lips, that's a typical male response to choke back emotion," he said. "It was good and genuine."

For those who plan to watch speaker after speaker take the podium, Hartley and other public speaking analysts said there are several cues one can look for when trying to determine the truthfulness of politicians.

As a general rule, Hartley encourages people who are unsure of a speaker to pay attention to the way his or her body moves, perhaps even more so than the words coming out of the speaker's mouth.

"Illustrators, or body movements, are indicators of what your brain is thinking," Hartley said. "It's your body punctuating your thoughts. A person should have synchronicity between the two."

Politicians Should Listen to Their Mothers: Pointing Is Rude

There are few politicians, Hartley said, who are capable of keeping their pointer finger under wraps during a speaking engagement, despite the negative effect on an audience.

"Pointing makes people feel like you're accusing them of something," Hartley said. "It shows the person is trying to make you believe something."

Last night, Clinton managed to reel in his desire to point at the audience, Hartley said.
