This is an excerpt from an article HERE about how some CIA agents moonlight for such firms as Hedge Funds, Merchant Banks, and other Global Financial Giants. Isn't it nice to know that all that expensive publicly funded education and training is helping out the private sector, especially Hedge funds?
“Tactical Behavior Assessment.”
"Unlike polygraph machines, the TBA technique allows examiners to work without hooking up their subject to a series of wires. The subject never knows he’s being scrutinized.
Polygraph machines work by measuring a person’s physical responses, such as heart rate, that indicate stress. Analysts using the machine need to sit with their subject for a long time. They have to establish a person’s physiological baseline, so they begin with a “control” conversation about neutral topics, before they can begin grilling the subject. Conducting an interview and doing a thorough analysis of polygraph results can take hours.
TBA focuses on the verbal and nonverbal cues that people convey when they aren’t telling the truth. Psychologists familiar with the method say it works because human beings just aren’t hard-wired to lie well. Holding two opposing ideas in your brain at the same time — as you have to do in order to tell a lie — causes a phenomenon they term “cognitive dissonance,” which creates actual physical discomfort. And when people are uncomfortable, they squirm. They fidget ever so slightly, they pick lint off their clothes, they shift their bodily positions.
Agents look for the physical indicators of lying. They watch for a person shifting anchor points. If the person is leaning forward on one elbow, does he switch to the other one? Interrogators watch for grooming gestures such as adjusting clothes, hair or eyeglasses. They look to see if the person picks at his fingernails or scratches himself. They watch for the person to clean his surroundings — does he straighten the paper clips on the table or line up the pens? If he does, he could be lying.
(I would like to say, to be honest, that people have all sorts of reasons to shift around in chairs, not the least of which is a bad back or even a sore hemorrhoid.)But, I digress....
"To obtain verbal clues, agents listen for several kinds of statements. They’ll listen for qualifying answers, phrases that begin with words like “honestly,” “frankly” or “basically.” The agents will be listening for detour phrases like “as I said before ...” They’ll want to hear if the person invokes religion — “I swear to God” — or attacks the questioner: “How dare you ask me something like that?”
Other red flags: Complaints —“How long is this going to take?” Selective memory —“To the best of my knowledge.” Overly courteous responses —“Yes, sir.”
