Bristol Lie Detector Test

10 Things to consider before taking a Lie Detector Test in Bristol with Lie Detectors UK who were awarded The Best Polygraph Testing Company in the UK and are owned by the Director of the UK Polygraph Association. Tests are £399 at the HQ Office and £499 in Bristol.

1. What exactly does a Lie Detector Test in Bristol entail?

A Lie Detector Test, also known as a Polygraph, identifies falsehoods by observing physiological shifts in Bristol. The Polygraph is the tool operated by the certified and skilled Examiner in Bristol. This device measures physiological responses to specific questions using a proven methodology. The Bristol-based firm, Lie Detectors UK, is a recognized and certified Lie Detection entity that employs only accredited APA and UKPA professionals in Bristol.

2. How does the Polygraph function?

The Polygraph tracks physiological variations such as blood pressure, perspiration activity, circulation, and torso movement in the individual being examined. Typically, the Polygraph Examiner contrasts varied reactions to set questions over several tests against answers from honest and deceptive queries to interpret the data and determine if the individual was lying or being honest. The outcome provided post-examination in a report showcases the conclusions from the certified examiner at Lie Detectors UK conducting a Lie Detector Test in Bristol.

3. What's the accuracy of the Lie Detector Test in Bristol?

Numerous scientific analyses indicate that when an accredited APA professional utilizes contemporary equipment and methods, like those at Lie Detectors UK, a single-issue examination using the Utah method can achieve a precision rate of 92% to 95%. A handful of studies suggest even greater accuracy, as some businesses might claim.

4. What's the price of a Lie Detector Test in Bristol?

The cost of our Lie Detector Test ranges from £399 to £499. The lesser fee applies at our main office, while the greater charge is for at-home visits or nearby office rentals. All rates are all-inclusive. A deposit is taken upon reservation, with the balance due on the test day. For multiple tests, we offer significant discounts on subsequent ones. Contact us for a detailed quote.

5. Which questions are used and for what reason?

Initially, we advise discussing your situation over the phone to determine the Polygraph Test’s appropriateness. Our most precise method involves a single-issue test comprised of three closely related questions about one topic, optimizing Polygraph Test accuracy. We focus on fact-based questions, avoiding emotional or intent-related ones. Lie Detectors UK examiners in Bristol also consider potential excuses someone might present after failing a Polygraph Test in Bristol.

6. Techniques used for questioning in Lie Detector Examinations

During the Lie Detector Test in Bristol, the Examiner poses three distinct question types. Lie Detectors UK adheres to accuracy standards, crafting directed lies, irrelevant, and pertinent questions tailored to each situation. The Examiner collaborates with you to frame the most apt questions for your scenario, ensuring everyone’s satisfaction before commencing tests.

7. Pre-assessment discussion

Before initiating the Lie Detector Test in Bristol, a preliminary interview spanning up to an hour takes place. Here, the Examiner delves into the case details, elucidates the entire procedure, and addresses client queries. A basic Polygraph Test is conducted, acquainting the subject with the experience. This helps the Examiner make any adjustments for optimal chart readings. A thorough review of all queries ensures the subject comprehends each one.

8. Gathering Data and Scoring Charts in Bristol

At least three charts are generated per subject, with questions rearranged. A chart average establishes the result. The Bristol Lie Detector Examiner conducts a comprehensive data review before presenting outcomes: No Deception Detected (Pass), Deception Detected (Fail), or the infrequent Inconclusive outcome when proper methods are used. Results are shared verbally and via a detailed three-page report, which can be mailed to your Bristol residence or printed at our main office.

9. What are the age requirements for a Polygraph Test in Bristol, and can it be taken during pregnancy?

We can test individuals as young as 14, but testing those under 18 necessitates complete parental approval and a maturity assessment. Pregnant women can be tested, provided the pregnancy is complication-free and progressing normally.

10. Polygraph's Past and Future

In 1906, James McKenzie, a Scottish Surgeon, introduced the Lie Detector test, building on his cardiology background. The core of this instrument, now called the Polygraph or Lie Detector, was the ability to capture and evaluate heartbeat and perspiration fluctuations. In 1921, John Larson, an American Policeman, refined this tool for forensic applications. Then in 1925, Leonarde Keeler enhanced Larson’s design, substituting smoke paper with ink pens, increasing its efficacy.

Lie Detectors UK, when conducting a Lie Detector Test in Bristol, always employs the single-issue approach to maximize precision. The validity may be compromised by inappropriate questions, an uncertified examiner, outdated machinery, or an unsuitable testing setting. Will My Anxiety Show as Deception When I’m Truthful? Definitely not. We frequently address this widespread concern. Test-takers often exhibit nervousness throughout the entire process; however, we assess responses to specific questions rather than the individual’s overall anxiety or nervousness. To put it plainly, if anxiety was a significant factor, the failure rate would be much higher. Instead, we observe around an 80% success rate. The Polygraph Examiner in Bristol will collaborate with you to ensure the experience is as straightforward and reassuring as possible. Baseline Question Examination Lie Detectors UK’s professionals in Bristol employ the Baseline Question Examination to establish a physiological reference point. Baseline questions are posed in conjunction with pertinent questions to determine the truthfulness of a respondent. An adept Examiner will adhere to the Directed Lie Technique while selecting the appropriate queries for the examination. Before undergoing a Lie Detector Test in Bristol, all questions are thoroughly reviewed with the participant.

What Is Eye-tracking?

This method employs pupil changes, yet its accuracy, at 85%, doesn’t match that of a Polygraph Test. Eye-tracking for Lie Detection in Bristol observes minute shifts within the pupil to evaluate a subject’s honesty in response to questions, but it demands the individual to be proficient in reading.

Voice Stress Analysis

Until not long ago, Vocal Stress Analysis was in use. However, its credibility has been questioned. It examines fluctuations in voice strength, tone, and pitch.

Brain Observations

Functional MRI scans track brain oxygen utilization, spotlighting regions engaged when assessing truthfulness. However, findings suggest it’s not consistently dependable.

Nonverbal Behaviour

Using fast cameras, involuntary facial cues or micro expressions are captured. In Bristol, these fleeting expressions can hint at honest or deceptive tendencies. But many studies show their inconsistency.


Historically, compounds like Ethanol, Sodium Thiopental, and Cannabis were used to extract information without a person’s agreement. Even though various substances have been tried in Lie Detector Tests in Bristol, no single drug is universally effective.

I was very satisfied by the professionalism of the examiner. The service was absolutely necessary for me and even though it is expensive I consider it money well spent in the larger picture of life. Couldn't have managed without the support they gave me, I really felt my nerves would let me down but as explained they didn’t.

I never thought I'd be put in a position to have to do a lie detector test but after 6years of being accused of cheating I decided to do the test for my own peace of mind. I had visions of the jeremy Kyle show but everything was explained to me and Jason put me at as much ease as he could. After getting the true result I wanted it cleared my name and made me realise the whole issue was deeper within my partner as he made every excuse to not believe the test. The test is 100% accurate as I could not control what my body was doing it will only give a result of lying if you are lying. Jason was brilliant with aftercare to myself and my partner and I cannot thank him enough for what he done. Finally i have closure that I needed and I recommend anybody to do this test and with this company if you are ever in that position I found myself in!
