When a deceptive person is devising a story to tell a lie, there’s an increase in cognitive load, or brain activity. If someone has the capacity to create a story without increasing how the brain reacts to this process, then that person will appear less deceptive. The pupils react involuntarily to an increase in cognitive load and for that reason EyeDetect has shown a superior level of accuracy compared to all other lie detection solutions on the market used to pre-screen job candidates and to conduct periodic evaluations of current employees.
