Detecting Terrorists by Smelling Fear
The technology relies on recognising a pheromone – or scent signal – produced in sweat when a person is scared.
Researchers hope the ”fear detector” will make it possible to identify individuals at check points who are up to no good.
Terrorists with murder in mind, drug smugglers, or criminals on the run are likely to be very fearful of being discovered.
Seems like yet another technology that will be swamped with false positives.
And is there any justification to the hypothesis that terrorists will be more afraid than anyone else? And do we know why people tend to feel fear? Is it because they’re up to no good, or because of more benign reasons—like they’re scared of something? This link from emotion to intent is very tenuous.
