Deception Is Futile When Big Brother's Lie Detector Turns Its Eyes on You | Threat Level | Wired.com: The US Army founded a polygraph school in 1951, and the government later introduced the machine as an employee-screening tool. Indeed, according to some experts, the polygraph can detect deception more than 90 percent of the time—albeit under very strictly defined criteria. “If you’ve got a single issue, and the person knows whether or not they’ve shot John Doe,” Honts says, “the polygraph is pretty good.” Experienced polygraph examiners like Phil Houston, legendary within the CIA for his successful interrogations, are careful to point out that the device relies on the skill of the examiner to produce accurate results—the right kind of questions, the experience to know when to press harder and when the mere presence of the device can intimidate a suspect into telling the truth. Without that, a polygraph machine is no more of a lie-detector than a rubber truncheon or a pair of pliers.
