Potentially offering a powerful new tool against terrorism, researchers have found a novel way to detect deception: in the liar’s blushing face.
The technique, described in the journal, Nature, uses a thermal camera to detect sudden, involuntary shifts of blood flow in the face. The system performed as accurately as a traditional polygraph, the scientists report.
Yet the camera can provide answers instantly, and does not require a highly trained specialist to operate it or interpret its results. This makes it far better suited than the polygraph for a new, high-tech approach to security that is already raising the hackles of civil libertarians: the screening of large numbers of citizens, at airports and other sensitive areas, who have done nothing wrong.
"The next decade is going to see the development of truly accurate lie detectors, "said Stephen M. Kosslyn, an expert on detecting lies and a professor of psychology at Harvard University.<
