Merseyside Lie Detector Test

10 Considerations Before Undertaking a Lie Detector Test in Merseyside with Lie Detectors UK, Honored as the Top Polygraph Testing Firm in the UK, and Owned by the Director of the UK Polygraph Association. Testing Costs £399 at HQ Office and £499 in Merseyside.

1. What is the Purpose of a Lie Detector Test in Merseyside?

A Polygraph, or Lie Detector Test, identifies deception by monitoring physiological responses in Merseyside. Trained and experienced Polygraph professionals in Merseyside employ this instrument to record and quantify physiological reactions to a series of formulated questions using an approved technique. Lie Detectors UK, based in Merseyside, is an acclaimed Lie Detection company that exclusively employs qualified APA and UKPA Examiners.

2. How Does the Polygraph Function?

The Polygraph tracks physiological changes, including blood pressure, sweat gland activity, blood flow, and upper body movement. The Polygraph Examiner typically compares reactions to various questions, including truthful and deceptive inquiries, to analyze charts and determine the subject’s veracity. The examination’s result is then reported by a certified Lie Detectors UK Examiner conducting a Merseyside Lie Detector Test.

3. What is the Reliability of a Lie Detector Test in Merseyside?

Numerous scientific studies indicate that when a qualified APA examiner utilizes the latest equipment and techniques, such as those employed by all Lie Detectors UK examiners, a single-issue test using the Utah technique achieves accuracy levels ranging from 92% to 95%. Some studies suggest even higher accuracy levels, although these are limited in scope.

4. What is the Cost of a Lie Detector Test in Merseyside?

Lie Detector Test fees with Lie Detectors UK vary from £399 to £499, with the lower rate applicable at our headquarters and the higher rate for home-based or nearby office tests. All prices are fixed and inclusive, with a deposit due upon booking and the remainder payable on the test day. Subsequent tests receive significant discounts; contact us for a quote.

5. Which Questions Are Used and Why?

We prefer an initial phone discussion to ensure a Polygraph Test is suitable for your case. Our most accurate technique is a single-issue test, consisting of three closely related questions on a single matter, maximizing Polygraph Test accuracy. We focus on fact-based questions, avoiding emotional or intent-based inquiries. Lie Detectors UK Examiners in Merseyside also consider potential excuses in case of test failure.

6. Questioning Techniques Employed in Merseyside Lie Detector Tests

During a Merseyside Lie Detector Test, subjects face three question types: directed lie comparison, irrelevant, and relevant questions, tailored to each case following accuracy guidelines. The Lie Detector Examiner collaborates with you to craft suitable relevant questions, ensuring all parties are satisfied before conducting tests.

7. Pre-Test Interview in Merseyside

Before initiating a Merseyside Lie Detector Test, a pre-test interview lasting up to an hour commences. The Examiner thoroughly discusses the case with clients, explaining the process and addressing their queries. A basic Polygraph Test is conducted to familiarize the subject with the experience, allowing the Examiner to make minor adjustments for better chart readings. Subsequently, a comprehensive review of all questions ensures the subject’s full comprehension.

8. Data Collection and Chart Scoring in Merseyside

Each subject undergoes a minimum of three tests, with questions presented in slightly varied sequences. The Lie Detector Examiner in Merseyside calculates an average of these charts to determine a result, which can be No Deception Indicated (Pass), Deception Indicated (Fail), or the rare Inconclusive result. Test results are conveyed verbally and in a three-page report, available upon request and mailed to your Merseyside residence. At our headquarters, we provide printed reports for you to take home.

9. Age Requirements and Pregnancy for Merseyside Polygraph Tests

The minimum testing age is 14. For individuals under 18, we mandate full parental consent and assess the minor’s maturity. Pregnant women can undergo a Lie Detector Test in Merseyside, provided their pregnancy is complication-free.

10. Historical and Future Perspective of the Polygraph

In 1906, Scottish Surgeon James McKenzie invented the Lie Detector test, originally focusing on heart surgery. The instrument we now recognize as the Polygraph or Lie Detector evolved from the capability to measure and record variations in increased heart rate and sweating. In 1921, American Police Officer John Larson improved the Polygraph for forensic use, and in 1925, Leonarde Keeler enhanced Larson’s equipment by substituting ink pens for smoke paper, increasing efficiency.

Accurate Results From a Lie Detector Test in Merseyside

Accuracy of a Merseyside Polygraph Test Merseyside Polygraph assessments demonstrate up to 95% accuracy when conducted with suitable equipment, trained examiners, and appropriate questions. Lie Detectors UK exclusively employs the single issue method for utmost precision during Merseyside Lie Detector Tests. Accuracy may diminish due to improper questioning, unqualified examiners, outdated equipment, or unsuitable testing environments.

Can Nervousness Implicate Falsehood? Certainly not; this frequently asked question is unfounded. Nervousness persists throughout the test, but we assess reactions to questions, not anxiety. In reality, nervousness would result in universal failure, yet we observe pass rates of approximately 80%. Our Merseyside Polygraph Examiner strives to ensure your comfort throughout the process.

Control Question Technique Merseyside Lie Detector Examiners at Lie Detectors UK employ the Control Question Technique as a physiological baseline. Control queries help establish correlations with relevant questions to detect deception. A skilled Examiner adheres to the Directed Lie Approach when selecting appropriate test questions. All questions are thoroughly discussed with the examinee before the Merseyside Polygraph Test.

What Is Eye-tracking?

Eye-tracking, a screening tool, measures pupil dilation but offers 85% accuracy, less reliable than Polygraph Tests. Subjects must possess proficient reading skills. Eye-tracking for Lie Detection scrutinizes minute eye movements within the pupil to assess truthfulness in response to a series of queries.

Voice Stress Analysis

Voice Stress Analysis, previously utilized, is highly unreliable, assessing variations in voice intensity, frequency, and pitch.

Brain Observations

Functional magnetic resonance imaging (fMRI) scans identify oxygen utilization in the brain, highlighting oxygen-utilizing brain regions to detect deception. However, results have proven this method to be unreliable.

Nonverbal Behaviour

High-speed cameras observe micro-expressions or involuntary facial gestures, potentially revealing truthful or untruthful behavior. Nonetheless, this method lacks reliability in numerous case studies.


Historically, truth drugs like Ethanol, Sodium Thiopental, and Cannabis were employed to extract information involuntarily. However, no single substance universally yields results, as various drugs have been tested without consistent effectiveness.

Frequently Asked Questions

Private Polygraph Examiner reports are presently not admissible in UK Courts, despite the UK Government employing over 40 Polygraph Examiners to assess sex offenders on probation and terrorism suspects. Our primary client base includes private individuals and businesses both in the UK and abroad. While a significant portion of our work at Lie Detectors UK involves relationship-related cases, we also handle allegations, theft, and various other case types, including Pre-Employment matters in Merseyside Lie Detector examinations.

A Polygraph, commonly known as a Lie Detector machine, records a subject’s physiological autonomic responses to questions. These physiological indices encompass blood pressure, blood flow, pulse rate, respiration, skin conductivity, and movement.

A Merseyside Polygraph Test entails no discomfort or pain. Some minor discomfort may arise from the blood pressure cuff during the examination; however, each test typically lasts only three to four minutes.

The overall duration often varies based on the specific case and the examinee. However, the entire procedure typically spans around two hours, with no duration shorter than ninety minutes. It comprises three stages: the pre-test, the examination, and the post-test phase.

Results are verbally conveyed to you upon test completion if the Merseyside Examiner does not require a second opinion. This allows ample time for a thorough discussion of your test with the Lie Detectors UK Examiner in Merseyside. A comprehensive report will subsequently be furnished, either via email or as a printed copy, or both upon request.

Reducing the number of questions to lower costs is not feasible. A multi-issue Lie Detector Test, addressing multiple matters, significantly diminishes accuracy levels. We generally discourage such tests, and if conducted, clients are informed of the reduced accuracy compared to a single-issue test.

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!

Got in touch to ask about taking a lie detector test due to problems within a relationship I was part of. Jason was great with comms, honest and sincere after I explained my predicament to him. His honesty stretched to the point where we both agreed that taking the test wasn’t in my best interests due to the circumstances I am in and for me that’s highly commendable. Thank you Jason, integrity is high on my agenda and I can safely say it is on yours too after our recent comms.
