The thought of undergoing a lie detector test can be terrifying and intimidate most people. Sitting there with wires and tubes attached and wrapped around your body give most people goose bumps. Even with nothing to hide, the sight of the metal box instruments sitting next to you will strike momentary fear into you. How then the lie detector does works and what are the procedures involved in taking polygraph tests?
A lie detector test, also known as polygraph testing, is becoming a popular method of proving innocence and finding out the truth in the UK today. Although there is widespread criticism of the techniques used in polygraph testing, the credibility of the test itself is still high, given the modern methods and new uniformity regarding the testing system used in lie detector tests. The main aim of a lie detector test is to find out if the person being tested speaks the truth or not. The test doesn’t read what’s on the person’s mind; it detects changes in the person’s physiological responses as a result of answering questions given to him during the test.
Since polygraph testing is all about questions, answers, and physiological responses, many people ask what exactly is the mode of questioning done during these tests. This article will cover two of the common questioning techniques examiners utilise during a polygraph test.

The Lie Detector Test has been internationally recognised as a psychological tool or instrument which enables a trained examiner to strategically interrogate a subject person to determine the truth. Historically, the test was used for detecting criminal...
Since its introduction in 1921, lie detector testing, as well as its accuracy, has always been a controversial issue in both the scientific and public domains. In fact, despite the popularity that it has gained in the cultural realm over the years, the veracity of polygraph tests continues to plague our endless search for truth.
Xenophanes once said: “Pure truth no man has seen, nor shall ever know.” While there may be some truth in this statement, man’s search for truth did not waver. Since the beginning of civilizations, man has struggled to distinguish the lies from the truth of his very existence and since then, techniques have been invented and reinvented to seek out the truth and weed out the lies.
One of the most prolific truth-seeking techniques that man has developed is the association of truth and lies to the physiological reactions exhibited by a person in the face of deception. Primitive as it is for some people, this simplistic technique has been used through the years, and up to this date, it has remained the most important consideration in truth-seeking examinations. This led to the modern-day polygraph or lie detector test.
As in every truth-seeking process, the polygraphic lie detection process starts with research. Relevant information on the examinee and the facts about the case surrounding the examination are gathered and studied. Action plans are also created before the actual testing is conducted. Once completed, the actual lie detection examination can start.
The polygraph is an instrument, more commonly referred to as the lie detector. It is used to measure, analyze, and record physiological reactions while the examinee is asked a series of Yes or No questions. Invented in 1921 by John Larson, a medical student and a police officer from Berkeley, California, this machine was originally developed in accordance to the mandate of the then-police chief of Berkeley, August Vollmer, for the police force to use science to be more law-abiding and avoid the third degree. It was first created to identify reactions based on the systolic blood pressure test pioneered by psychologist William Moulton Marston, who later on became more popularly known as the creator of the comic book superheroine Wonder Woman.
The polygraph is not only widely used by companies but also by private persons. Knowing when and where to use a polygraph is an absolute must-do for anyone who is seeking the truth. As it is publicly known people lie a lot, let us be honest, we lie all the time. Some are very talented liars and while doing it, they hardly give any signs which could make it possible to identify a fraud. Others have very visible signs which clearly suggest that the things that we are being told are not particularly true. That is why a lie detector can prove to be so useful. A professional polygraph accurately monitors reactions of the subjects body to certain questions asked and gives good foundations for the examiner to determine whether the person questioned is lying or not. Below are listed a couple of cases in which a polygraph should be used:
Polygraph testing has always been a controversial matter for all kinds of reasons. The most known controversy regards the devices accuracy as well as the possibility of cheating the results of the test. The lie detector produces it’s results based on the measurement of blood pressure, pulse, breathing or sweating. One can generally say that the polygraph is responsible for measuring the basic functions and operations of our body. A licensed examiner is responsible for the appropriate interpretation of the results of the polygraphs measurements and based on the differences found, certain conclusions are made concerning the fact whether the examined is telling the truth or not. This would mean, that the accuracy of the test depends greatly on the examiner. Which in some ways is true. The negative side of the polygraph test is that it is a form of an interrogation. For some people, especially innocent ones, this can prove to be extremely stressful, that on the other hand can have a significant influence on the results of the lie detector test, which in some cases could suggest that the innocent person examined is actually guilty. But there is no need to worry, a professionally trained examiner is able to determine whether a person is stressed because of the fact that he or she is lying or because of the fact that they are overwhelmed with the given situation.
After a sexual offence has taken place, the most important aim is to provide care and support to all victims and ensure that the person responsible faces the appropriate sentence. For sexual offenders, the time spent behind bars is meant to change their behaviour and prepare them to re-enter the society with a new state of mind. It is important that a person ending their time in prison returns to a normal life without the public taking a risk that he or she will repeat their crime and cause pain to their previous and new victims.
