Few things are easier than telling a lie, and few things are harder than spotting one when it is told to us. We have been trying to suss out liars ever since Cain fibbed to God about murdering Abel. God was not fooled, hearing the blood of Abel cring out from the land, the rest of us do not have such divine lie-detection gifts! But that doesn't mean we are not trying! Quitely over the past five years, the US Dept. of Defense have dramaticcaly stepped up the hunt, millions of dollars are believed to have been poured into lie-detection techniques as diverse as infrared imagers to study the eyes, scanners to peer into the brain, sensors to spot liars from a distance, and analysist trained to scrutinize the unconscious facial flutters that often accompany a falsehood! Wazee mnasemaje, je bongo tunahitaji hiiitechnology kama ipo?
