Use of lie detector in relationships

Trust is the most important factor in a relationship. Almost every relationship is based on trust and once the trust of the other person is lost, the relationship fails. No matter how hard you try to make things work, the relationship cannot survive without trust. It may sometimes take years to regain the lost trust and even after that, it is not certain that the trust will be restored. In many cases, adultery cannot be proved definitively and the only way to be certain about it is by going through the lie detection lie detector test. The results of a polygraph lie detector test are 90-95% definitive and thus can help to mend a broken relationship back. Also the results of such exams also widely depend on the experience of the person conducting the lie detector test. If the person conducting has a lot of experience, then the lie detector

What Polygraph Examinations Are

The term polygraph – literally meaning “many writings” – pertains to the method of simultaneously recording various physiological activities and observing any pattern changes in them. Those who wish to determine the truth behind a statement will often rely on a polygraph examination, or in simpler terms, a lie detection test. Law enforcers often utilize this method of examination to determine the innocence of an individual. What Comprises a Lie Detector Test A typical lie detector test includes three areas: a pre-test interview wherein the required paperwork is collected and the examinee is asked a few short questions, chart collection wherein different polygraph charts will be collected by the examiner, and the analysis of test data wherein the generated charts are studied and interpreted. This is when the results are determined. If deemed appropriate by the examiner, the examinee will be allowed to explain his or her responses to the

When Lie Detection Tests are Used

Most people know about the use of lie detectors to detect deception. However, many may have a limited perception as to the range of purposes they can be useful for. Cases When Lie Detection Tests are Used Resolution of Criminal Cases Lie detection systems are most useful in giving strength to an accusation or defense when there is lack of physical evidence that links a suspected offender to the particular criminal case. They also help ensure the truthfulness of the persons testifying in court and the reliability of their testimonies. Since lie detection tests are not infallible, there are several courts in the USA that do not allow the presentation of test results as useful court evidence. However, there are certain states and federal courts that allow it in special cases and when there is mutual agreement between parties involved in the criminal investigation. Scrutiny of Sex Offenders There are

The Facts You Need to Know

The Facts You Need to Know about Lie Detectors and Their Reliability There are times when you need to ascertain if somebody is telling the truth or not. There are people who are good at telling lies. Sometimes, there are also cases of one person’s word against another. A lie detector test or a polygraph test can be helpful in these instances. The test is considered to be essential for matters that concern security, crimes, and personal affairs. What is a Lie Detector Test? Lie detector tests, commonly referred to as polygraph tests, measure and analyze key body reactions through a series of “yes or no” questions. Based on the person’s body reactions as he answers the questions, these tests can tell whether a person is telling the truth or is lying. The body reactions refer to the physiological functions of the body. These are subconscious reactions to circumstances. These

The Fundamentals of Lie Detector Testing

Lie detector testing is a method that is commonly used to arrive at the truth when something is being investigated. While the validity of the polygraph tests is still up for debate, modern technology has made it possible for these lie detector tests to yield more accurate results. Polygraphs record and measure several physiological indices during testing. These indicators include blood pressure, blood volume, pulse rate, respiration, and skin conductivity among others. Results are evaluated and compared against accepted standards. Professional opinions are based on the discrepancies noted on the recorded data. Historical Backgrounder In 1921, John Augustus Larson developed an instrument that measured a diverse amount of physiological indices. A medical student at the University of California Berkeley and a police officer assigned to the Berkeley Police Department, Larson used the instrument for forensic investigations. Larson’s instrument provided continuous readings of physiological data which improved on the prevailing system

How does a Polygraph Test Happen?

Polygraph tests are not things to make fun of. Lie detector testing is the process of verifying the truthfulness of statements made by persons of interest. These statements are often part of an investigation and it is important that lie detector tests establish the truth behind them. Device Components A typical polygraph test machine has three major components, namely the blood pressure cuff, the pneumographs, and the galvanometers. Blood pressure cuffs are attached around the upper arm of an examinee. It covers the branchial artery and provides a continuous tracing of the person’s cardiovascular activity such as his heart rate, blood pressure, and blood volume. Pneumographs are the two rubber tubes fastened around the person’s chest and abdominal areas. These tubes are used to monitor his respiratory activity during the test. Galvanometers are the two protruding electrodes attached to the client’s fingers. These components are used to obtain a reading

All About the Polygraph Exams

Polygraph tests are vital to various departments and institutions because of their capability to prove the innocence – or guilt –of an individual. The results may not be acceptable evidence in court, but they can turn tables and influence people. It captures various physiological activities such as the following: Blood Pressure The heart rate or the blood pressure is measured through a cardio-sphygmograph cuff on the upper arm of the examinee. A length of rubber tubing is attached to the cuff and runs to the polygraph machine. If a digital polygraph is used, the signals obtained are converted to electrical signals. Respiratory Rate Two air-filled rubber tubes, called pneumographs, are placed around the examinee’s chest and abdomen. Displacement of air takes place inside the tubes as muscles of chest or abdomen expand. Electro-dermal Activity This measures the amount of sweat that appears on your fingertips. Science shows that the fingertips

Uses and Benefits of Lie Detector Tests

Lie detector tests are often portrayed in film and television as a method by which truth is extracted from the person taking the witness stand. In these shows, the wires attached to the perpetrator’s body is also connected to a machine, which etches a couple of lines onto a piece of paper. A qualified professional would then determine whether the person is telling the truth or not. To the untrained individual, it all seems like a figment of one’s imagination. However, there is a science to it. Psychology reveals that a person experiences physiological responses that varies depending on the situation he’s in. Experts believed that when a person tells a lie, he experiences internal changes, which is often unseen by the naked eye. Thus, they have devised a method which is able to determine whether a person is experiencing these internal responses. They were able to come up with

All about Lie Detector Tests

The polygraph test, also known as lie detector test, is a method by which a person’s physiological indices are measured and recorded while being asked a series of questions. These indices include, but are not limited to, blood pressure, pulse, respiration, and skin conductivity. A person is believed to have varying physiological responses depending on his thoughts. This is where lie detector tests are anchored. It is believed that these responses will be able to reflect the truth or falsity of a person’s statement. Brief History Humanity’s quest for wanting to know the truth dates back to the Middle Ages. Back then, torture was used to elicit information from a person’s lips. Luckily, these are no longer sanctioned in these modern times. Fast forward to 1895, a device invented by Cesare Lombroso was used to aid police cases in determining a person’s blood pressure. Later on in 1904, Vittorio Benussi

Uncovering the Truth about Lie Detector Tests

In a dark room with several lights glowing, there sat a tall, lanky guy. There were several wires hooked to him while two men in uniform hawked around him. ‘Did you steal the money inside the vault?’ sternly asked the taller guy in uniform. The tall, lanky guy sweated like a pig as he whimpered and said no. The other guy nodded his head as he looked at a machine scribbling lines and letters on paper. This is how a polygraph test is usually depicted in movies and crime dramas. But this dark room scenario is far from reality. A lie detector test is done in a clean and well-lit room. The polygraph technician is seated in a table facing the machine and a computer. The apparatus is hooked on to the examinee. The examiner politely asks the questions. As depicted in the scenes above, a polygraph is an apparatus
