DHS To Use Body Odor As a Lie Detector

The US Department of Homeland Security is studying lies, damned lies, and smells. They hope to prove that human body odor could be used to tell when people are lying. The department says they are already "conducting experiments in deceptive behavior and collecting human odor samples" and that the research it hopes to fund "will consist primarily of the analysis and study of the human odor samples collected to determine if a deception indicator can be found."

Polygraph, and other assorted gadget do NOT detect lie. Ever. What they possibly detect is stress, (fear and its little cousin nervousness for example) which in some case may or may not be correlated to a lie. It is all based on putting the idea that "it works" in the mind of people it tests, and indeed sometimes law enforcement get confession from people (they CAN use the confession but may not use any lie detector crap, and recently even that was put under fire). There isn't really a good scientific background on it The Lie behind the lie detector.

Using odor instead of breathing heart beat and so on will not bring anymore science is this than pissing into a violin and expecting a concerto.
