Abstract and Keywords
Detecting lies is a difficult task. People lie frequently, and most lies are trivial. However, some lies can have very serious consequences. Research has repeatedly demonstrated that people are not good at detecting deceit, with accuracy typically equating to a guess. Indeed, there are many impediments to the process, including that most people are quite adept at lying, there are large individual differences in people’s behaviour when they lie, often the person suspected of lying is not known to the lie detector, and that people look for the wrong cues to deceit. Technology has produced numerous aids which are claimed to detect deceit, but the problem is that such technologies typically detect anxiety, but lying may or may not lead to anxiety. Conversely, so may truth-telling, hence the difficulty. However, recent research, discussed here, concentrates on making the liar’s task more difficult, and shows promise in distinguishing liars from truth-tellers.
