When it comes to telling when someone is lying, we currently have very few options, but a team of Israeli researchers claims to have come up with something better than anything we’ve seen before.
Using stickers printed on soft surfaces containing electrodes that monitor and measure the activity of muscles and nerves, a team of researchers led by Prof. Dino Levy from Tel Aviv University, discovered that some people involuntarily activate muscles in their cheeks and eyebrows when they lie. No sensors had been able to measure these subtle muscle contractions before, but the innovative ones invented by Prof. Yael Hanein and sold by Israeli company X-trodes proved sensitive enough. Tests revealed a 73% success rate of lie identification, better than any existing technology.
“Many studies have shown that it’s almost impossible for us to tell when someone is lying to us. Even experts, such as police interrogators, do only a little better than the rest of us,” Prof. Levy told Israel21. “Existing lie detectors are so unreliable that their results are not admissible as evidence in courts of law – because just about anyone can learn how to control their pulse and deceive the machine. Consequently, there is a great need for a more accurate deception-identifying technology.”
Based on the assumption that facial muscles contort when we lie, Prof. Levy’s team attached the novel stickers to a number of test subjects’ cheeks and eyebrows, and made them sit across from each other while uttering a series of words, some true and some false. One of them wore headphones and had to repeat the words being told to them, only sometimes they had to lie. The person sitting on the other side had the difficult task of figuring out when they were being lied to. At some point, they changed roles.
