1. Lie Detector Tests were Created in 1906
Cardiologist Sir James McKenzie built one of the first polygraph tests in 1906. The polygraph machine has gone through many stages since then but it was only computerised in 1992.
2. Many Industries use Polygraph Tests
Polygraph machines are applied in a broad range of different sectors. Law enforcement agencies, the government, public defenders, attorneys and even some private companies all use polygraph tests.
3. Polygraph Tests are Used by Courts Even though Considered Unreliable
The precision of lie detector tests is undecided, but despite that, they are still being utilised in court as well as police departments all over the world. Determining that despite their uncertain character they are still seen as an adequate way to reveal the truth by many established authorities.
4. Showcased on TV
Surprisingly enough polygraph tests saw an increase in reputation not because of their use in criminal investigations but because of their performance on television.
5. The Polygraph Test Is Still The Most Accurate Test For Detecting Lies
A study was completed by The National Academy of Sciences to evaluate its effectiveness. The conclusion they came to was that although other methods are available none have been found to be as powerful as the polygraph test.
6. The Role Of The Examiner
Without a trained and qualified examiner, a lie detector test could quickly give strange interpretations. The analyst is responsible for preparing and administering the test, and they need effective presentation and logical abilities. The absence of an examiner is one of the principal causes home lie detectors are found to be inaccurate.
