Oxford Lie Detector Test

10 Points to ponder upon prior to undergoing a Lie Detector Test in Oxford via Lie Detectors UK, crowned as The Premier Polygraph Testing Firm in the UK, overseen by the Chief of the UK Polygraph Association.

1. What precisely is the function of a Lie Detector Test in Oxford?

The Polygraph, often referred to as a Lie Detector Test, identifies falsehoods by observing indications of physical alterations in Oxford. This device is employed by proficient Polygraph specialists in Oxford to measure and document physiological responses to a set of structured queries following a certified method. Lie Detectors UK, an established Oxford enterprise, is a celebrated and certified Lie Detection entity employing only accredited APA and UKPA professionals in Oxford.

2. How is the Polygraph operated?

The Polygraph tracks physiological alterations in a test-taker, including blood pressure, perspiration levels, circulation, and torso motion. Typically, the Polygraph Specialist will contrast varied reactions to designed questions over several tests, matching answers from honest and misleading questions to decipher the readings and determine the individual’s honesty. The test findings, presented post-analysis in a report style, will incorporate an evaluation from the adept expert at Lie Detectors UK conducting a Lie Detector Test Oxford.

3. What's the reliability of a Lie Detector Test Oxford?

Numerous scholarly investigations indicate that when a competent APA specialist employs cutting-edge tools and methodologies—as all Lie Detectors UK specialists do—a single-topic test employing the Utah method can attain a precision rate of 92% to 95%. Some select studies might suggest even higher precision rates, as certain firms might assert.

4. What's the expense for a Lie Detector Test Oxford?

Undergoing a Lie Detector Test via Lie Detectors UK costs between £399 and £499, the latter for services rendered at our primary facility and the former if it involves home visits or renting a nearby office. Costs are unchanging and comprehensive. A partial payment is required during reservation, and the balance is settled on test day. Discounts are available for additional tests—contact us now for an estimate.

5. Which questions are chosen and for what reason?

An initial telephonic conversation is preferred to assess the applicability of a Polygraph Test to your scenario. Our most reliable method is the single-issue test, encompassing three closely related queries on one matter, enabling optimal precision during a Polygraph Examination. We limit ourselves to factual inquiries, steering clear of emotional or intent-based ones. Lie Detectors UK’s examiners in Oxford also contemplate potential justifications someone might offer upon failing an Oxford-based Polygraph Test.

6. Approaches to Questioning within Lie Detector Examinations

During the Lie Detector Test Oxford, a candidate will face three kinds of queries presented by the Specialist. Lie Detectors UK adheres to established accuracy standards to devise comparative falsehoods, unrelated, and pertinent questions tailored for every situation. The Polygraph Specialist collaborates with clients to craft the most fitting relevant questions for the scenario, ensuring all involved parties are content before initiating tests.

7. Interview prior to the test

Before commencing the Lie Detector Test Oxford, a preliminary interview that might extend to an hour is conducted. In this duration, the Specialist discusses the case in-depth with clients, elucidating the entire procedure and addressing any client concerns. A rudimentary Polygraph Examination is undertaken, familiarizing the individual with the Oxford-based Polygraph Test experience. This also lets the Specialist fine-tune certain aspects for superior readings during the actual tests. An exhaustive review of every query ensures the participant comprehends each one and the response method.

8. Gathering Data and Chart Interpretation in Oxford

A minimum of three graphs are prepared for every participant, with questions rearranged subtly. A chart mean provides the outcome, and the Lie Detector Specialist in Oxford scrutinizes the collated data prior to announcing results, which could be No Deception Detected (Pass), Deception Noticed (Fail), or an Unclear outcome—a rarity with appropriate methods. The Lie Detector Test outcomes are conveyed verbally and through a comprehensive three-page document, mailed to your Oxford address upon request. Reports are also printable at our central office for immediate collection.

9. Age prerequisite for a Polygraph Test in Oxford & considerations for expecting women?

The youngest age eligible for testing is 14; however, testing individuals below 18 mandates complete parental approval, with added emphasis on the minor’s maturity. Expecting women can be tested, provided the pregnancy progresses without complications.

10. Polygraph's Past and its Evolution

  1. James McKenzie, a Scottish cardiologist, birthed the Lie Detector test concept in 1906. Capturing and measuring fluctuations in heartbeat and perspiration was this instrument’s primary functionality, now termed as the Polygraph or Lie Detector. Subsequently, in 1921, John Larson, a U.S. law enforcement official, introduced a refined and more precise Polygraph variant for forensic purposes. By 1925, Leonarde Keeler further enhanced Larson’s apparatus by swapping smoke paper with ink implements, elevating its efficiency.

Accurate Results From a Lie Detector Test Oxford

Oxford Lie Detector Test Precision Reliability of Lie Detector Examinations in Oxford When conducted using appropriate tools, competent professionals, and precise questions, Polygraph assessments can reach a reliability of up to 95%. Lie Detectors UK, when performing a Lie Detector Test in Oxford, strictly employs the single issue technique to ensure optimal precision. The effectiveness can be compromised by inadequate questions, an untrained professional, outdated tools, or an inappropriate testing environment.

Nervousness Doesn’t Equate to Deception, Does It? Certainly not; this query frequently arises in our daily interactions. An individual will consistently exhibit anxiety throughout the assessment, but we evaluate responses to specific queries rather than overall nervousness or stress. If anxiety were a significant factor, everyone would potentially display deceptive tendencies, yet we observe a pass rate of approximately 80%. The Polygraph professional in Oxford endeavours to make the procedure as straightforward and relaxed for you as feasible.

Approach to Control Questions In Oxford, Lie Detector’s UK professionals utilise the Control Question Test to establish a physiological reference point. Control queries are posed to correlate with pertinent questions to determine a subject’s veracity. A proficient professional will maintain the Directed Lie Methodology when selecting the most apt questions for evaluation. Prior to conducting a Lie Detector Test Oxford, all questions are thoroughly reviewed with the participant.

What Is Eye-tracking?

A method involving pupil variation exists, but with an accuracy rate of 85%, it isn’t as reliable as a Polygraph Test and mandates that the participant possesses proficient reading abilities. For Lie Detection, eye tracking examines minute eye movements, particularly in the pupil, to determine a respondent’s honesty in answering a set of queries.

Examining Voice Stress

Until recently, Voice Stress Analysis was employed, but it has been deemed highly inconsistent. It analyses fluctuations in voice strength, tone, and pitch.

Assessing Brain Activity

Functional MRI machines measure brain oxygen consumption and spotlight areas using oxygen to deduce if a participant is being deceptive. This approach, however, has often shown to be less dependable.

Analysing Non-verbal Cues

High-speed cameras capture micro or involuntary facial gestures. These micro expressions can hint at honest or dishonest behaviours, but in numerous studies, they’ve proven to be inconsistent.


Historically, agents such as Ethanol, Sodium Thiopental, and Cannabis, among others, were used to extract details from individuals without their knowledge. Despite multiple drugs being trialled, no single compound has universally effective results.

Frequently Asked Questions

Private Polygraph Examiners’ reports aren’t considered by UK Courts, even though the UK Government employs over 40 Polygraph Examiners for assessing probationary sex offenders and potential terror suspects. Our main clientele includes private individuals and businesses, both domestically and internationally. Most of our assignments at Lie Detectors UK involve personal relationships, but we also handle cases of allegations, theft, and a variety of other matters, including pre-employment screening with an Oxford Lie Detector.

A Polygraph, commonly termed a Lie Detector, gauges a subject’s physiological autonomic reactions to queries. It monitors indicators like blood circulation and pressure, heartbeat rate, breathing patterns, skin conductivity, and movement.

There is zero pain during an Oxford Polygraph Test. A slight discomfort may arise from the blood pressure cuff, but each assessment is brief, lasting only three to four minutes.

The length varies based on case specifics and the person being tested, but typically, it spans about two hours, never less than ninety minutes. It comprises three segments: pre-test briefing, the actual test, and the post-test discussion.

Post-test, immediate verbal feedback is provided by the Oxford Examiner unless a second opinion is necessary. This allows for a comprehensive discussion with the Lie Detectors UK examiner in Oxford. A detailed report follows, either electronically or in print, and if printing on-site isn’t feasible, a mailed copy is dispatched without additional charges.

Arranging for a Lie Detector Test in Oxford is efficient, secure, and discreet. Before finalising a slot, we prefer a preliminary chat to ensure the test’s appropriateness for your case. A non-refundable booking fee of £150 is necessary, post which you’ll receive confirmation details, including the Oxford address and examiner’s contact. Online reservations are available on our website.

The focus isn’t the number of questions but their nature. For optimal accuracy during a Lie Detector Test in Oxford, we encourage single-issue tests. Aiming to cut costs by reducing questions isn’t viable. Multi-faceted tests, where numerous topics are addressed, compromise the accuracy significantly. Lie Detectors UK prefers singular topics, alerting clients if a multi-issue test might offer reduced precision.

The £150 deposit for an Oxford Lie Detector Test is non-refundable to ensure commitment. After this, we reserve the time slot and make necessary preparations. The outstanding amount is settled on the test day via card payment.

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.

Could not have been any happier with the service. Jason was informative and friendly from the off and did everything he could to make everybody feel comfortable and at ease.
