Many British citizens know of lie detector tests through American talk shows, but not everyone is aware that lie detection services are available here in UK. If a test is conducted by a competent and experienced polygraph examiner, the results have an average accuracy of 96%. Studies also show that by using the latest training, techniques and equipment (along with an experienced examiner), the accuracy levels are as high as 98%. These are the most common incidences where polygraph tests are used in the UK.
Most people generally associate polygraph testing with the criminal justice system. It can be a key investigative tool within the courtroom, but it doesn’t provide indisputable evidence. Polygraph services are available to defendants and also to government departments and law enforcement agencies. Using a polygraph service has become more popular as it speeds up trialling time and in most cases, at a lesser expense.
Lying in a family court has become increasingly popular within the past decade. Anything can be fabricated from a person’s income to their assets. Falsely made claims of child abuse and domestic violence have also been an issue. Now the accused can use a polygraph service to help in their cases and to ensure all parties are truthful.
Proving falsely made allegations
Whether you are accused of theft, fraud or going against a severe allegation like murder, a polygraph service can help you in proving your innocence. There was a case, based in Ireland, where a defendant (a county councillor) voluntarily took a lie detector test as he was being convicted of assaulting a man in a pub at Trafrask. He presented his lie detector results to the High Courts and they quashed his conviction.
Investigating new employees for corporations has been made easier since polygraph testing was introduced. Now recruiters are able to substitute curriculum vitae checks, drug screenings and security background checks by issuing a lie detector test. Not only would this significantly streamline and speed up the hiring process, it would also reduce the costs associated with hiring a new employee. It would also result in a more honest employee base. Even though this is more common for corporations based in the U.S, there is still many companies and government departments that would employ an examiner to give random periodic polygraph screenings in the UK. This is particularly common within government departments to ensure that there are total honesty and security in their line of work.
Corporate fraud and theft
Fraudulent behaviour in the workplace can take many forms. Misrepresenting a company’s financial information or activities is one of the most common cases. It’s done to mislead the public and to increase profits. When this is carried out and investigated, you can be looking at a sentence starting at 5 years for each indictable offence. You can use the results from a lie detector test to help your case or even get it overthrown.
Resolving domestic disputes
Polygraph services often play a key role in resolving domestic disputes. Many who wish to take a polygraph test are seeking peace of mind. The most common case for polygraph testing within relationships are accusations of infidelity. This can be as broad as being sexually involved with another person or used to determine the extent of your partner’s ‘sexual’ activities conducted over the internet. Polygraph testing can determine if visits to pornographic sites or dating sites were made but it is important to have an experienced examiner as it could make a difference in this particular area. The wording of test questions is crucial to achieving a successful examination as people interpret words differently. Other disputes can arise from accusing your partner of having a gambling or drug/alcohol addiction.
Verification of media sources
The 21st century has brought us new ways to find information like never before. The growth of social media allows anyone to share potential newsworthy stories. This has changed how journalists find and distribute stories, but with that comes an increased danger of misinformation. Sources found by journalists must be reliable or else the integrity of their publication could be at risk. If they question the honesty of a source, then a polygraph test can be a great way to ensure that the truth is being told. Many tabloids and magazines publish stories without fully examining their sources. But, if your publication values facts and honesty, a polygraph test could preserve your reputation.
As you can see from above, there are many uses of polygraph testing here in the UK. Have you any experience or questions with any of the cases mentioned here? If so, get in contact with us or comment below!Read More
A s a beginner to the lie detectors, you have to understand how lie detectors work. Lie detectors do not give a result about truth or lies almost immediately. They have the best stuff to provide data. As polygraph testers, we receive and analyze these data by using various resources. We are very conscious about what is going on in a suspected person’s body. This is because we have to analyze these changes in a proper way for enhancing the overall accuracy of the result.
Residents of many countries believe in the lie detector these days. This is because advanced resources and scientific data do not give an inaccurate result.

The government security checks involve the lie detection system because criminal investigations in a proper way. You have to keep focusing on every aspect of this lie detector test and make a good decision.
There are so many questioning techniques used in the polygraph testing service in our time. Control question test is one of the most important questioning techniques used for investigating the criminal case. This test is conducted to arouse the overall concern of the subject’s past trustworthiness. A person who tells the truth feels fear towards the control questions.
A clear pattern of physiological responses to relevant questions is very helpful to identify the deception easily. A good response to every control question indicates no deception. There may be a chance for an inconclusive result when there is no difference between control and relevant questions.
The guilty knowledge test is the most outstanding polygraph procedure at this time. This multi-choice test involves some elements related to the guilty subject. If a guilty suspect has answered these questions correctly, then he or she involved in the crime. This kind of test is conducted when investigators ensured that a guilty suspect can answer the question.ectors.
There is no doubt that the polygraph is highly reliable, providing the person using it is properly trained and the technique they use is validated. The American Polygraph Association (APA) has gathered over 200 studies on the subject. Based on twelve separate studies involving 2174 actual cases since 1980, evidence suggests that qualified polygraph examiners are 98% accurate in their overall decisions.
The overall reliability of the polygraph testing is not questionable nowadays. This is because the most advanced resources provide the absolute support to polygraph testers worldwide. London Polygraph Ltd has the most successful records in this highly competitive profession. We use the latest yet reliable resources to conduct the polygraph test as efficiently as possible.

It is too difficult to decide on anything associated with the test devoid of the way in which figures are calculated. There may be a risk in terms of the oversimplification of such figures unreasonable. In such situations, companies, private individuals and government officers conduct a polygraph test for the second time.
Individuals who use a polygraph testing nowadays do not take account of the inconclusive test results as negative. They do not use such elements against the examinee of the polygraph test.
Things involved in a polygraph test
A lie detector test includes the following elements
- A pretest interview
- Charts collection
- The polygraph chart analysis
- Consultation with relevant people
The time required to conduct a polygraph test for an average case last two to three hours. Pretest interview is the longest part in every polygraph test. You have to understand this truth and improve your expertise about this test.
We give crystal clear instructions about the actual polygraph testing phase. We make sure that examinees understand all these instructions without any doubt. We are happy to make clear their doubts and answer their questions regarding this profession.
We understand our role to define legal rights related subjects in detail as per requirements of examinees. We do not fail to explain how every aspect of polygraph equipment provides the most accurate result. We discuss about the main subject of the polygraph test in detail. We review all questions that we will ask during the polygraph test.
Polygraph test components
Once we and the examinee have geared up to take part in the polygraph test, we attach the most relevant components to the examinee. Even though these components are very stressful, they are not painful. We attach a couple of pneumograph tubes across the upper chest as well as the abdomen of the examinee. The next step is to attach two metal plates on the index and ring finger of the examinee. We attach a blood pressure cuff around the examinee’s upper arm carefully.
We ask questions that we were reviewed more than a few times before the polygraph test. We conduct two to three different polygraphs. We record all these processes in the audio and or video format. We make sure that the examiner and the examinee only in the room where the polygraph test is conducted.
How do polygraph examiners detect the lie?
An ideal polygraph can test the human physiology in the following aspects
- Changes in the skin resistance
- Relative blood volume and the pulse rate
If a person is not truthful, then his or her physiological changes reveal it. A person is considered to be deceptive when the following physiological changes take place.
- Increase or decrease in the heart rate of blood volume
- Changes in perspiration and respiration
If a person is truthful, then his or her physiological patterns remain same. Opponents and proponents of the polygraph techniques argue about the overall differences between their statistics regarding the test.
There may be a false positive or a false negative error in the polygraph test. A false positive takes place when an honest examinee is reported as deceptive. A false negative takes place when a dishonest examinee is reported as truthful. The main reason behind the polygraph error of any category is a lack of professionalism of polygraph examiners.
If polygraph specialists misconduct the test or misread the physiological data revealed by the polygraph charts, then there will be such mistakes. The examinee has to be honest in what he answers during the polygraph test. The examiners of the polygraph test have to keep concentrating on every change in the pulse rate, blood pressure, muscle movements, perspiration and respiration of the examinee.
Some people argue that people who have failed to be aware about the polygraph test may feel frustrated and failed to prove their innocence during the test. On the other hand, highly qualified polygraph testing service providers in our company are very conscious about their professionalism and accuracy of the result.

- An appraisal of the overall emotional state of the examinee from the beginning to end of the polygraph
- Medical records that indicate the physical condition of the examinee
- The most appropriate techniques for overly nervous and responsive examinee
- A few genres of control question for appraising the response capabilities of the examinee
- The factual analysis of different aspects of the case information in detail
- Detailed review of questions
- A pretest interview
- Quality control reviews
Lie detector accuracy
The more popular the polygraph becomes, the bigger the disagreements about its use. And it has become very popular. With each new challenge comes the need of, once again, proving that the lie detector is a legitimate device to be used in all kinds of cases and as technology develops, so does the accuracy of the device. It is only a matter of time for it to be a fully usable tool.
So what is the secret of the polygraph? Although it is sometimes called a “Lie Detector”, that’s not what it does. Of course at the end of the day, the result of the tests is a verification if a given statement is true or not but before that happens, many processes have to be completed. So in general the polygraph (or Lie Detector) is responsible for measuring the reactions of the body while a statement is given. Thanks to the monitoring of heart rate, breathing rate, pulse or skin conductivity we are able to determine what reactions have taken place in the body and what could their consequences be.
Years of research have shown, that the body has natural reactions of hidden nervousness when a false statement is given. These reactions are all uncontrollable by the mind which is what makes the whole examination so accurate. A person has no control over their pulse or blood pressure. It just changes. Many scientists and researchers have not only discovered that the body reacts to lies but have also determined what these changes look like.Iit is the polygraphs job to make it possible to identify symptoms of lying.
Discussion have been raised about the possibility of cheating the test. Though explained many times, this matter tends to come back over and over again. It is practically impossible for a normal human to cheat the test. As mentioned above, the examination is very dependent on the body’s reactions, which, as we established, are impossible to control. Therefore in order to cheat the polygraph, one would have to attain the ability of controlling one’s pulse and blood pressure which is highly impossible for a normal person. Of course, there have been individuals which have managed to crack the test and it is said that specialist training will give the ability of cheating, but such things are only available for certain individuals. As an example we can use all kinds of secret agents. During their training they go through a special course allowing them to learn how to control their inner processes. This is performed in order for them to be able to keep any state secrets even when connected to a polygraph. Only such extreme cases may be taken into account which leads to the odds of such a person taking the test to be minimal.
There is also fear about the so-called false positive. This may sometimes occur but is very rare. The matter itself is heavily dependent on the examiner and his knowledge. False positives may be caused by stress of the examinee as also technical issues connected with the lie detector. A professional examiner will realize such factors and will take them into account when analyzing the results.
