We hear anywhere from 10 to 200 lies a day, and we spent much of our history coming up with ways to detect them, from medieval torture devices to polygraphs, blood-pressure and breathing monitors, voice-stress analyzers, eye trackers, infrared brain scanners, and even the 400-pound electroencephalogram.
Dnevno čujemo od 10 do 200 laži, a kroz cijelu smo povijest tražili načine da ih prepoznamo, od sredstava za mučenje  u srednjem vijeku, detektora laži, kontrole krvnog tlaka  i disanja, analizatora glasa, nadzora pokreta oka,  infracrvenih čitača mozga, pa čak i EEG-a teškog 180 kg.
