DHS To Use Body Odor As a Lie Detector

Posted by samzenpus on Thu Mar 12, 2009 06:57 AM
from the we-can-smell-the-truth dept.
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."

      It just dawned on me. Collecting "scent samples" is the same thing the East German government did. For every citizen. Is Homeland Security taking us down that same road?

        They took "smell samples" from prisoners, to track them down with dogs. What they didn't know (or didn't want to know, you'll never be sure) was that dogs don't really track using the scent of the "game", they follow the trail it leaves on the ground until late in the hunt. And by the time the dogs are close enough to pick the target out by scent, you can use visual identification (i.e. see him).

          Um, no. Every creature on earth has an unique scent. Scent will actually come out of a human being, or other "game" in cone shaped form. This is why search and rescue units will work a patch of land moving in the expected cone shape (based on what the dog picks up) when trailing a victim in a search. I have done search and rescue and that is the logic they use because it works. The first thing they do when a new volunteer comes on is show them how it works. Tracking, what you were referring to, also uses the same concept but, with the individual scent being left by brushing against the ground itself.

          In a nutshell, this scares the hell out of me.

              Land's End, Cornwall (the most south-westerly point of Great Britain) to Inverness (most northerly city in Scotland) is only 730 miles.

              Many people in the UK would fly that distance -- though it would be awkward, both places are very remote. But our alternative -- a train, with lots of legroom, space for luggage, a table, a power point for your laptop, a toilet etc -- doesn't really exist in the USA, outside a few locations.

              (A train from Land's End (Penzance) to Inverness takes 14 hours, or 16 hours if you take a sleeper train overnight.)

          Well, okay, but here's the simple fact: DHS pulls aside for additional questioning or searches fewer than 10% of all passengers. If you don't want to be searched or questioned, simply don't give them a reason to do so.

          That may be OK individually, but generally (not just with smells and aeroplanes) it's a dangerous route to go down collectively. Only a few are questioned, so everyone tries to conform to what they think the authorities consider normal. So the authorities lower their thresholds and then everyone becomes even more conforming, etc. It leads to everyone 'self-censoring' their behaviour to some degree to please government and security guard's prejudices.....it's far better for people to feel secure against unreasonable harrassment. It's not that your suggestion is necessarily bad - but if you can be bothered with baking soda then you ought to also be bothered opposing it politically.

      It won't be able to reliably tell anything about anyone, except perhaps that they were a little bit nervous about something, just *exactly* the same way current lie detectors do.

      The problem with lie detection, as quite a number of people have said endlessly over the years, is that the assumption is made that a lie is something that somehow the body has a physiological problem with. Clearly this is swan songs of morality, as amorphous and dynamic as they are, being applied directly to the human nervous system, and somehow people are surprised to discover that there hasn't been a lie detector in the world that's been proven unquestionably to work at all.

      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).

        and if a lie is not detected you could be

    People being interrogated would frequently be asked to sit with their palms face down on a piece of cloth, usually stuck to the chair. After the interrogation, the cloth would be removed and placed in a jar for later analysis. I don't believe it's ever been admissible as evidence in any western court, but that's obviously what the whole DHS "proof" is all about.

    Quite why one would invest so many resources in this when fingerprints and DNA are already reliable forms of identification I don't know, and I strongly suspect that the "indicator" of deception will be flawed for much the same reasons the results of a polygraph are flawed - I can understand how someone who's stressed might well emit a different sort of sweat than someone who's just hot, but trying to define a "liars sweat" reeks (hohoho) of pseudoscience to me.

    Who knows, maybe there's something in it, maybe the article is making too much of things, maybe I've got my paranoid hat on. But it still seems worryingly like the whole "this man is the serial killer cos his writing is all weird" argument to me.
