"Popular culture is fascinated with the ability to detect liars. Lie detector
tests are a staple of police dramas, and TV shows such as
Poker Face feature
“human polygraphs” who detect deception by picking up tell-tale signs in
people’s behaviour.
Records of attempts to detect lies, whether by technical means or by skilled
observers, go back at least 3,000 years. Forensic science lie detection
techniques have become increasingly popular since the invention of the
polygraph early in the 20th century, with the latest methods involving advanced
brain imaging.
Proponents of lie detection technology sometimes make grandiose claims, such as
a recent paper that said “with the help of forensic science and its new
techniques, crimes can be easily solved”.
Despite these claims, an infallible lie detection method has yet to be found.
In fact, most lie detection methods don’t detect lies at all – instead, they
register the physiological or behaviour signs of stress or fear."
