Fear Detector To Sniff Out Terrorists

Hugh Pickens writes "Evidence that the smell of fear is real was uncovered by US scientists last year who studied the underarm secretions of 20 terrified novice skydivers and found that people appear to respond unconsciously to the sweat smell of a frightened person. Now the Telegraph reports that researchers hope a 'fear detector' will make it possible to identify individuals at check points who are up to no good. 'The challenge lies in the characterization and identification of the specific chemical that gives away the signature of human fear, especially the fear in relation to criminal acts,' says Professor Tong Tun at City University London, who leads the team developing security sensor systems that can detect the human fear pheromone. The project will look at potential obstacles to the device, such as the effects of perfume and the variances in pheromone production and if the initial 18-month feasibility study is successful, the first detectors could be developed in the next two to three years. 'I do not see any particular reason why similar sensor techniques cannot be expanded to identify human smells by race, age or gender to build a profile of a criminal during or after an incident,' Tong added."

      Y'know.... a man can change the scent/pheromones his body gives off as easily as taking a drug like cyproterone. The effects are temporary, but taking it in doses of about 50mg/day for a week before flying will have a big enough impact on the way your body produces pheromones that most people won't be able to read you properly. Stop taking the drug, and your body resumes normal operation...

      Not suggesting, of course, that the terrorists would think to use a drug that, in people with a Y-chromosome, is usually used to treat transgenderism (and occasionally used to treat prostate cancer), but there are a very large number of drugs out there on the market, some available over the counter, that will affect your body's hormone balance, and will in turn affect the pheromones that your body produces. With so many ways to screw with the results available, I'd be very surprised if they could get such a system to work properly with an acceptable false positive/false negative rate....

      That is exactly what I would assume to be the case. Though there may be the fear of getting caught but... I doubt it. I think the false positive rate on anything like this is going to be through the roof.

      Frankly, I will laugh and hoot the first time someone is awarded a huge sum because of the trauma they experienced when their panic disorder brings on the start of an attack and trips off the sensor. Because, as we all know, being suddenly pulled aside by a person in uniform is exactly the sort of thing that a person having an uncontrollable panic attack needs to calm them down. The sort of ham handed treatment typical of people who feel that someone paying them and putting them in a silly uniform gives them the right to harass other people is exactly the sort of thing that will really move their treatment forward.

      Terrorism is a largely imaginary threat. Panic disorder is a real and debilitating disorder.

      I am seriously against damaging real people to catch imaginary ones.

      Terrorism is a real threat, it's just nowhere near as large a threat as some would make it out to be.

      Yeah, well, we're talking about airport terrorist screening here. Terrorism on airplanes is pretty much over. The idea that we need to protect against guys getting on with box cutters is absolutely ludicrous. If anything, the shift in public perception of hijacking should have allowed a relaxing of security at airports, as the passengers will immediately hogtie, pummel, and sedate any idiot dumb enough to try anything. Really, the only thing left to look out for is explosives, and that's a fairly simple chemistry problem. All this shit with taking off shoes, smelling us for fear, and peering through our clothes with machines is expensive security theater to mitigate a problem that's already been solved.

    The idea that there's a special chemical signal for "fear in relation to criminal acts" seems to come out of absolutely nowhere. Shouldn't there be some research into whether such a chemical signal exists before device development occurs? If it's not a magic detector of latent emotion or the cause of emotion so I'm not sure how much better it would be than noticing which people "look a bit afraid". It's going to be just as susceptible to picking up people who find flying difficult or are worried about being falsely accused of being a terrorist because they look funny.
