Clues that suggest people are lying may be deceptive, study shows
Researcher Jia Loy, from the University of Edinburgh, created a computerised two-player game in which 24 pairs of players hunted for treasure. Players were free to lie at will.
Researchers coded more than 1100 utterances produced by speakers against 19 potential cues to lying -- such as pauses in speech, changes in speech rate, shifts in eye gaze and eyebrow movements.
The cues were analysed to see which ones listeners identified, and which cues were more likely to be produced when telling an untruth.
The team found listeners were efficient at identifying these common signs.
Listeners make judgements on whether something is true within a few hundred milliseconds of encountering a cue.
However, they found that the common cues associated with lying were more likely to be used if the speaker is telling the truth.

That's normal. It's far more likely that somebody that glances away is telling the truth because they don't have to monitor the reaction so closely to know if they're getting away with it.
Ultimately, there isn't any way of really knowing without having the facts in hand or in the future scanning their brain.

It's easy to tell when a politician is lying. There are at least three 100% reliable tells. The first is if they open their mouth to speak. The second is if they set pen to paper. The third is if they begin to press keys on any type of keyboard, real or virtual.
I thought I was wrong, once, but I was mistaken. Why do you ask?
