Researchers at University of Edinburgh have found that the perception that a person has fidgety eyes when telling a lie was wrong as eye movements does not indicate whether a person was lying or not.
The researchers used two groups of volunteers for the study with the eye movements of the first group being recorded when they were telling lies or truths.
AdvertisementThe recordings were then shown to the second group of volunteers who were asked to identify whether the person was lying or not.
The researchers found that the volunteers were unable to identify correctly who was lying or who was telling the truth by just watching eye movements. "A large percentage of the public believes certain eye movements are a sign of lying and this idea is even taught in organizational training courses. Our research provides no support for the idea and so suggests that it is time to abandon this approach to detecting deceit", lead researcher Dr Caroline Watt said.
