Guideline to Catching Liars by Examining Nonverbal and Verbal Behaviour - Observational Guidelines (5): Do not make up your mind too quickly about whether a person is lying. Judging whether someone is lying is not straight forward, however once people have made up their mind whether someone is telling the truth or not they have a tendency to interpret additional information to support their decision (the confirmation bias). This is where lie detectors run the risk of failing to notice further important information - or misinterpreting the information.
