How do polygraph tests work?

polygraph test uk

Polygraph examination was developed within psychology and the behavioural sciences to use physiological indicators of deception to accurately detect lies.

The earliest version of a polygraph instrument was developed in 1921.

Physiological recording for deception indication has undergone technological development to bring about the devices and techniques used today.

The modern polygraph is now an integrated, state of the art, computerized system that involves continuous physiological recording, technique, data analysis and science to determine whether a subject is being honest in his or her responses to specific or relevant questions.

Lie detector tests record different bodily responses that occur in the subject during testing, and which study and research within the behavioural sciences have shown whether a person is being deceptive or not, to accurately detect lies.

When people lie they cause an increased activation within their sympathetic nervous system; this is shown within increased heart rate, blood pressure, respiration and perspiration.

Different sensors are attached to the body of the examinee to enable the recording of subtle physiological changes.

Physiological changes that are recorded and analysed within lie detector tests include:

  • Skin conductivity or galvanic skin response (sweating)
  • Blood pressure or blood flow
  • Heart rate or pulse
  • Respiration/breathing rate
  • Body temperature
  • Movement or fidgeting

Examination formats allow the combining and analysis of data collected from recording these physiological changes to assess the probability of a subject responding truthfully or deceptively and, essentially, to tell you whether a person is lying or being honest.

What happens in polygraph examinations?

We recognise at Bond Rees that booking and attending a lie detector test can be a daunting, unfamiliar and sometimes embarrassing process; we guarantee that you will receive an understanding and warm response to your enquiry with us and all of our examiners are friendly, non-judgemental and discreet.

Our polygraph examiners will listen to your needs and put you at ease, supporting you through the formulation of your test and the actual polygraph test itself and answering any questions you may have.

We have provided the below guide to advise you on how to book a lie detector test with Bond Rees and what testing consists of:

A guide to the testing process:

  • Call us today to discuss your needs and book a lie detector test at a time and location that suits you. We can often provide lie detector tests at short notice.
  • Once you have paid a deposit through card payment, one of our friendly and professional examiners will contact you to discuss the issues behind your need for a polygraph test and find out from you what questions you need answers to.
  • We use a model of lie detector testing which allows us to ask 3 main questions per test and enables specific incident testing; your examiner will help you to decide what 3 questions will get the answers and clarification you need.
  • The examiner will then write a bespoke and individual test to meet your needs, carefully formulating relevant questions to ensure the most valid and reliable results are achieved from your lie detector test.
  • The examiner will visit you at your chosen location and time and undertake a full and comprehensive polygraph test which will take between 30 to 60 minutes to complete depending on each individual test and the person sitting the polygraph examination.
  • Polygraph examination or lie detector testing uses sensors that are placed on the examinee’s body to detect physiological or bodily changes.
  • The examiner will undertake a short pre-interview with the examinee to gain a fuller understanding of the issues surrounding the test, explain the test to them, gain their consent to take part and help them understand what they need to do to ensure the test is valid and accurate.
  • The examiner will then place the sensors on the examinee’s body. The sensors are not uncomfortable and there is no pain caused by lie detector testing; it is all completely safe. You will not need to be unclothed for the sensors to work but you will need to remove a heavy jumper or coat so ensure you are wearing a suitable T-Shirt or similar underneath on the day of the test.
  • The examiner will conduct a practice or “acquaintance” test with the examinee which will ensure that the equipment is able to record their physiological reactions correctly and that the subject is suitable for polygraph testing.
  • An innocent person or persons answering truthfully need not worry about being found to be deceptive due to nerves or stress they are experiencing as a result of sitting the test; the practice test will provide a baseline for the polygraph examiner to distinguish which bodily responses indicate nervousness and which indicate deception in an individual.
  • The lie detector test will involve the examinee answering 3 sets of 11 questions; these questions will include the 3 relevant questions that you wish the test to resolve. They will also include irrelevant and comparison or control questions which provide the environment to enable the body to provide clear indication of deception or honesty, and to heighten the physiological reaction of a guilty person.
  • Polygraph tests record physiological responses made by the examinee through a computer software programme that converts this into data.
  • After the test, in some cases the responses provided by the examinee are obvious and the examiner will be able to give you a verbal result on the day. However, in most cases, the examiner will need to go away and thoroughly analyse the statistical data obtained using empirical scoring to ensure a valid and accurate result is provided.
  • You will always receive a clear and full report within 2 days of your lie detector test which will tell you the outcome of the polygraph testing undertaken. The polygraph test report will be emailed to you at the email address you provide and is yours to keep and share with those you want to prove the result to.

Your examiner will be an experienced professional and will not judge or react to anything you say or share so you can feel comfortable and confident about being honest and open about the questions you need to be answered.

How accurate are lie detector tests?

The American Polygraph Association is the leading world body for the use of evidence-based and scientific methods for detecting deception and credibility; it estimates the general accuracy of polygraph testing to be 87%.

Any agency or individual who advises you that their testing is of greater accuracy than this is providing you with an invalid and non scientifically verified figure and is likely to be dishonest or guessing. Accuracy claims need to have been subjected to robust, independently reviewed, objective testing and studies before they can be deemed valid and reliable and cannot just be made up to sound good!

However, psychologists agree that this is only half the story and accuracy is actually largely dependent on the polygraph examiner themselves; the robustness of polygraph evidence is dependent on how thorough an examiner is in the formulation of questions and the conducting of the polygraph test, and the extent of their knowledge and understanding of the physiology and psychology behind polygraph testing.

Many companies offering lie detector testing in the UK make reference to using “qualified polygraph examiners” or to being members of the American Psychological Association, the American Polygraph Association or the British Polygraph Association; in reality, there is no recognised UK polygraph examiner qualification and no official recognised body that regulates polygraph testing in the UK.

Lie detector testing is not a controlled or regulated industry and there is no universal standard in the UK. There is no law that prevents companies offering this service from being dishonest about their training or membership of alleged official bodies. Companies and examiners can also operate without the all-important in-depth background understanding or knowledge of human psychology that lie detection is based on.

However, you can feel reassured that at Bond Rees we choose to do things differently and to be honest and upfront with you about the qualification and validity of our lie detector test service.

UK Law and Polygraph Testing

In the United States of America, polygraph testing is employed within the criminal and legal system and used to provide evidence within the court. It is a respected and significant practice within the American legal system.

The results of polygraph testing cannot at this time be used or submitted to a UK court to prove a case.

Whilst polygraph testing is not currently recognised by English or Welsh courts presently, its value and use are not without support from official bodies; the highest-profile use within the UK of polygraph tests is by the probation service.

Optional use of lie detectors has been in place since 2007 in England and Wales for serious sex offenders that are on parole. Since 2014 the probation service has been permitted to impose mandatory polygraph examinations that are attached to the release conditions of an offender.

In February 2018, it was reported by the Ministry of Justice that 166 sex offenders had been returned to prison since the polygraph examinations had been introduced and highlighted concerning behaviours.

Currently, the same measures of mandatory polygraph examinations are being considered as part of the Domestic Abuse Bill when releasing domestic abuse offenders in England and Wales.

The National Police Chief’s Council is also undertaking work to understand the benefits of polygraph testing within policing and whether its use could be expanded. Currently, seven police forces in England and wales utilise polygraph tests on a voluntary basis for existing and suspected sex offenders.

Corporate lie detector testing is already used to assist companies in screening potential employees, within comprehensive pre-employment interviews or to determine the honesty of current employees when issues or theft or information breaches has been identified.

Polygraph results have the potential to be used in tribunals but are generally utilised at an earlier stage to settle disputes within employment. It would be the individual decision of the presiding judge whether to admit polygraph evidence or not to a tribunal.

Essentially, whilst currently, in the UK a polygraph report cannot be submitted as evidence to a criminal court, it is clear that this is a well respected and established practise that is used and endorsed by high profile official bodies.

What sort of issues can a lie detector test address?

Lie detector tests can be used in any areas where you think someone is lying to you or where you need to prove your honesty.

At Bond Rees we are experienced in and undertake lie detector tests for a range of different matters from getting to the bottom of suspicions in relationships to evidencing the guilty party in relation to theft or data breach within large companies.

You may be in a situation where you have little evidence but a hunch or suspicion that you need clarifying. A lie detector test can fill the gaps and provide the evidence and assurance you seek.

A lie detector test is a quick and stress-free way of resolving suspicions, arguments and accusations. Innocent subjects can prove their honesty and guilty persons are found out.

We are the UK's leading professional Polygraph Testing service

We undertake lie detector tests to resolve uncertainty in the following matters:

Relationship difficulties:

Do you think your partner, husband or wife are cheating on you or have cheated on you in the past? Do you feel that your partner is lying to you or keeping secrets from you? Are you being accused by your partner of cheating and want to prove your innocence to them and their family? Polygraph tests are able to resolve this matter quickly and clearly with relevant questions focused on the specific issues you wish to address.


Has something gone missing or been stolen from you? Do you have suspicions about who might have stolen from you but can’t prove it? Are there two or several suspected perpetrators and you can’t determine who is the guilty party, who was involved or who knew about the theft? Is someone accusing you of stealing and you want to prove your innocence? Polygraph testing offers a quick and definite way of determining who is and who is not responsible for a theft, who was involved and who knew what was going on or aided the crime. Careful formulation of test questions will enable you to find out all the answers you need regarding a crime you have been a victim to.

Employer Concerns:

Do you think an employee is lying to you and making a false illness claim? Do you think an employee has stolen from your company or shared information inappropriately? Do you think an employee has not been operating in the best interests of your company or has another agenda they are using your company to achieve. Polygraph tests can clarify any of your suspicions and uncover fraudulent or criminal behaviours, providing a secure base from which you can further address these behaviours with the perpetrator and take action to resolve the problem.

Issues with family or friends:

Do you think someone in your family or friendship circle has been lying about you, keeping secrets or behaving in a suspicious or concerning way? Do you think something is being kept from you or has a family member or friend done something that might be harmful to you or those you care about? Find out the truth about who you can or cannot trust, or what has happened in the past, with a lie detector test.

Frequently asked questions

Can I beat a lie detector test?

There are numerous hints and tips provided on google and other search engines around how to beat a lie detector test. Do they work? The straightforward answer is no! Very strong-willed human beings may be able to calm themselves enough to provide a steady pulse or breathing rate but polygraph examinations rely on the combining of data from several different physiological responses; no human is able to simultaneously control their temperature, blood pressure, body movement, respiration, perspiration and heart rate whilst also listening to and answering questions at the same time! It is simply not humanly possible! There is no substance that you can take that would achieve the bodily regulation required to pass a lie detector test either. Can you beat a lie detector test? No you can’t! Observed purposeful non-cooperation with a lie detector test will be recorded as an indicator of deception.

Can I take a lie detector test when I am pregnant?

There is no published evidence that pregnant examinees cannot be safely and effectively tested. There are individual cases where the pregnancy is risky and in these instances, a lie detector test would not be recommended purely for the increased stress and anxiety this may place the examinee under. The polygraph examiner will talk through any questions or worries you may have about undertaking a polygraph test when pregnant and will ensure that you are calm and comfortable throughout the process and do not experience any distress. Pregnant examinees are allowed to take as many breaks as they need during the testing process and this will not affect the results in any way.

Can I take a lie detector test when I am on prescribed medication?

Some medications can affect how your body responds:

Anti-hypertensive medication or medications that affect heart rate and blood pressure can affect polygraph results.

Antidepressant or anti-anxiety medications can also affect how your body responds to polygraph testing.

However, the practice or “acquaintance” test that is undertaken with the subject prior to the actual lie detector test will enable the examiner to calibrate the system to reflect any bias and establish a baseline for each individual on the day of testing. It’s important that you inform the examiner of any medication you are on so that they are aware and can prevent this from providing an inconclusive result.

Can I take a lie detector test when I am using alcohol or illicit drugs?

Being under the influence of alcohol or any illicit drug such as cannabis or cocaine will prevent you from being able to sit a polygraph test and achieve a valid and accurate result. You will need to wait until you are no longer under the direct influence of alcohol or illicit substances before taking a lie detector test.

If you are a chronic user of any substance you will need to make the examiner aware as this could impact on your physiological reactions. The examiner can then utilise the practice or acquaintance test to calibrate the system to your current baseline to prevent this from impacting on your results or causing an inconclusive result.

Can I use polygraph test results in a criminal court as evidence?

The results of polygraph testing cannot at this time be used or submitted to a UK court to prove a case.

How accurate is polygraph testing?

The American Polygraph Association is the leading world body for the use of evidence-based and scientific methods for detecting deception and credibility; it estimates the general accuracy of polygraph testing to be 87%.
