General

What is a polygraph?

A polygraph (= “many writings”) or lie detector is a device that continuously and simultaneously measures and records the course of physical parameters such as pulse, breathing or the electrical conductivity of a person’s skin during questioning.

Can I use it anywhere at home or on the go?

Yes. The Polygraph Pro is compact, light (~2 kg) and can easily be set up, whether at home or when traveling – all it needs is a stable surface and a USB cable connection to a laptop or PC.

What are lie detectors used for?

In principle, the lie detector can be used in any situation in which you need certainty about whether a statement is true. Whether as a fidelity test in a marriage or relationship, to solve a theft or simply as a party game – there are many possible uses.

How accurate are lie detectors?

More than 100 scientific studies on the accuracy of lie detector tests have been published. According to them, the accuracy of a properly conducted lie detector test is between 95% and 100%.

Can nervousness affect the lie detector test?

Being nervous before a lie detector test is nothing unusual. Nervousness cannot influence the test result – lies certainly can.

Is it possible to trick the lie detector?

Provided the person conducting the questioning is trained and qualified to carry out the test, this is very unlikely. The lie detector is a medical device that records changes in a person’s autonomic reactivity while they are being questioned. If a person tries to control their behavior in order to falsify the result, this becomes obvious to a trained examiner when looking at the polygraph recording.

How long should a complete lie detector test take?

A complete polygraph test usually takes 3 to 4 hours. It begins with a detailed preliminary interview in which the facts of the case are discussed and the test questions are jointly defined and explained in detail. The polygraph examination is then carried out in several standardized measurement runs in order to create a reliable data basis for the subsequent evaluation.

The polygraph examiner then analyzes the recorded measurement data and discusses the results in detail with the person tested. A professional polygraph examination is not a short test, but a structured and scientifically established examination process that is carried out with the utmost care, precision and sufficient time.
