What is a lie detector test and how long does it take?
The principle behind a lie detector, or polygraph, is relatively straightforward. Traditional interrogations provide ample opportunities for seasoned liars, as even experienced detectives can struggle to distinguish truth from lies. A lie detector, however, can discern the person’s true intentions by measuring subtle physiological reactions to questions, driven by subconscious instincts.
These reactions include:
- accelerated breathing,
- increased blood pressure,
- activation of sweat glands.
It’s important to note that some individuals should not undergo a polygraph test, particularly those with diagnosed neurological disorders (such as Alzheimer’s or Parkinson’s). Nonetheless, most tests yield reliable results. During a polygraph session, not only are case-related questions asked, but also control questions that help assess baseline responses.
How long does a lie detector test take, for instance, in the Border Guard or other services?
The duration of a polygraph test can vary significantly depending on the situation; tests may last up to several hours, though the short wait time for results often compensates for this.
Is the lie detector test reliable?
Professional and reliable polygraph tests are available at affordable prices, which is why they are widely used in state services and institutions. Lie detector tests are administered to police officers as well as officers and employees in agencies such as the KAS, Border Guard, and ABW. Given the widespread use of this solution, the answer to whether a polygraph test is reliable is nearly self-evident. Its main advantages are its accuracy and thoroughness— the device objectively measures physical reactions and expressions. Lying is a conscious act, always preceded by a brief instinctual response. The polygraph helps detect these critical subtleties in the examinee’s behavior, which would be challenging to observe by traditional means.
