Lie Detector What Lies Beneath
These questions may well mark the common mans closest brush with the lie detector, while viewing the immensely popular American show, The Moment of truth, that portray contestants in a tight spot, answering a volley of 21 intrusive questions while being strapped on to a lie detector, amidst an attentive and interactive audience of friends and family members.
Lies prove very costly or truth always wins, as substantiated by the show - the truthful contestants walk away with prize money, sometimes thousands of dollars, commensurate with the number of truthful answers.
All of us are familiar with lies, and though most have resorted to lies harmless or otherwise at some point, universally, it is difficult to take a lie lying down. Even though it is believed that a thousand lies may be needed to conceal a single lie, which should ideally act as a deterrent, lies have witnessed a rapid growth trajectory, both in magnitude and content, making it unbelievingly tough to discern the truth. For those who have mastered the art of lying and are at their creative best, it may take only the systematic ways of machines to crack devious minds.
The quest for truth at the subliminal level, especially when knowing the truth can make all the difference between life and death, may have inspired the invention of the Lie Detector. The lie detector, also called the polygraph, is a fascinating development of employing machines to delve into the human mind, to verify the connection between thoughts and words, to detect the making of deceit.
Chinese and Russians Search for Truth
Lie detecting technology, born thus, may have also taken a leaf out of the Chinese method of lie detection, practiced way back in 1000 BC. The Chinese believed that stress caused by lying produced certain physiological changes.
To ascertain guilt, the Chinese filled dry rice into the subjects mouth; during the examination, if the subject was guilty of lying, the stress induced in the body was thought to cut salivation, causing the mouth to go dry. The presence of such changes in the body caused due to the stress of lying formed the basis of establishing truthfulness or deceit.
It may be interesting to hear how Russians tracked deceit. To detect liars, the accused had to hold a red-hot iron or dip their hands into a pot of boiling water and remove an object. The hands would then be completely sealed or bandaged and checked three days later for any signs of injury - absence of any injury would directly imply innocence. They believed in the combination of truth attracting divine grace and truth triggering positive forces in the body which could promote healing. Further examples of crude means of extracting a confession include the infamous Salem witch trials in the US and various Inquisitions recorded in history as having been practiced all over the world.

The polygraphs done on MOT are unreliable. The examiner, the late Nick Savastano, was not using approved techniques to come up with his conclusions. Let's hope his successor is better at his job.
