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.

    Players were free to lie at will.

    When people are told they can lie for a game; any feeling of guilt or remorse are removed from most people.

    Whether or not you are talking to a complete stranger or to someone that you know personally makes a difference as well. How easy is it to lie with a straight face to your college buddy that you slept with their fiancée?

    A study like this is next to worthless.

    And the obligatory...
    How can you tell a politician is lying? Their lips move.

    I agree that the study is junk, but so is the notion that lie detectors - whether human or not - exist.

    Like... now? Very very had; I can't recall any joke with this punchline.
    'Cause otherwise no college buddy of mine has a fiancee today.

    Most people have an aversion to lying even if they are "free to lie at will". It's a learned reaction, but it's embedded in the lower brain, so not something you can consciously override, unless you're a sociopath or weren't brought up properly.
