What Questions Are Asked in a Polygraph Test?
Question Types and Real Examples

The Three Types of Question

Every comparison-technique examination is built from three ingredients. Relevant questions address the issue under investigation directly - they are the reason the test exists, and everything else on the chart exists to give them context. Comparison questions are deliberately broad, mildly uncomfortable probes, typically about general honesty across the subject’s life, engineered so that almost everyone produces a measurable response to them. Neutral questions - confirming your name, the day, where you are sitting - establish a calm baseline and give the recordings somewhere to settle between the moments that matter.

The three types exist because the scoring is relative. The test never asks did you react - everyone wired to a machine with their relationship at stake reacts. It asks did you react more to the accusation than to the uncomfortable-but-safe comparison probes. That relative logic is what makes question quality so decisive: a badly worded relevant question contaminates the very comparison the entire result is built on.

Alongside the comparison method sits a second family - concealed information formats - which ask no accusatory questions at all. Instead they probe whether the subject recognises specific details only someone involved could know, hidden among plausible alternatives. These need case facts that can be kept secret, so they suit thefts and investigations more than relationship disputes, and they are the logic that modern recognition-based EEG testing is built on.

One Examination, One Issue

The single most important discipline in question design is scope: one examination, one clearly defined issue. A test that wanders across infidelity, missing money and something from years ago in the same session is a test engineered to produce noise - each topic drags its own emotional weight onto charts that are trying to measure one comparison cleanly, and the scoring degrades accordingly. Every credible practitioner standard says the same thing, and it is the first thing cheap providers abandon.

This has a practical consequence for buyers that surprises people: if you genuinely have two separate questions - did the affair happen, and separately, where did the money go - the reliable answer is two examinations, not one sprawling test. A provider who cheerfully offers to cover everything in one sitting is optimising for your money rather than your answer. A provider who tells you to choose your single most important issue is doing their job.

Within the single issue, three to five relevant questions is the professional norm. Fewer than three leaves the finding resting on too little; more than five dilutes the charts and exhausts the subject. Each question then gets asked multiple times across repeated chart collections - so a compact, precisely worded set is repeated and measured, rather than a long list skimmed once.

What Separates a Good Question From a Useless One

Good relevant questions share a grammar. They describe concrete acts, not feelings or intentions - have you had sexual contact with, did you take, did you delete - because an act either happened or it did not, while feelings cannot be tested. They carry defined time frames - since a named date, during the employment, while staying at the house - so the subject cannot truthfully answer a different period than the one you care about. And they use words whose meaning has been agreed by everyone: in an infidelity case, what counts as cheating gets defined explicitly during the consultation, in the couple’s own terms, before any question containing it is finalised.

The banned list is just as instructive. No compound questions - did you take the money and lie about it forces two answers into one chart response. No legalese or euphemism the subject might parse differently under pressure. No questions about states of mind, memory of feelings, or what someone meant. And nothing the subject finds ambiguous even slightly: a question the person in the chair has to interpret mid-test produces a reading of their confusion, not their honesty.

Notice who benefits from this rigour: both sides. The commissioning client gets a result about exactly what they need answered; the subject gets a test they cannot fail through misunderstanding. When examiners push back on a client’s proposed wording - and good ones push back constantly - that friction is the service working, not the service being difficult.

What the Questions Look Like by Case Type

Infidelity and relationship cases - the most common bookings in the UK - build questions around specific acts within the relationship’s own definitions: whether the person has had sexual contact with anyone other than their partner since a named date; whether they have had physical intimacy with a specific named individual; whether they have deleted messages or apps to conceal contact; whether they have met someone in person that they told their partner they had not. Where the couple’s real dispute is about online behaviour, the questions say so explicitly - vague questions about faithfulness are exactly the ambiguity a good examiner refuses.

Theft and family-dispute cases centre on the item and the knowledge: did you take the specific money or property; do you know who did; have you knowingly given false information about it. That second question - knowledge rather than action - matters enormously in family matters, where the wound is often not only the missing jewellery but the suspicion that someone is covering for someone else.

Workplace and business cases follow the same grammar with tighter scoping: did you take the missing takings; did you share the client data with anyone outside the company; have you deliberately withheld information from this investigation. Historic-allegation and pre-relationship clearing-the-air cases can also be tested, provided the allegation can be pinned to concrete acts and periods - the consultation does the pinning, and an honest examiner will say plainly when an allegation is too diffuse to test reliably.

How the Questions Get Agreed

The pre-test consultation is where all of the above happens, and it follows a predictable arc. You bring the situation and what you need answered - in whatever state it is in; nobody arrives with test-ready wording. The examiner extracts the single issue, drafts precise questions, and then walks them with both the client and the subject: every word explained, every definition agreed, every ambiguity surfaced and reworked. The final set is fixed before testing begins, and nothing outside it will be asked.

The subject’s position in this process is stronger than most people expect, and a professional service keeps it that way. Testing is voluntary and consent is a requirement, the subject sees and agrees every question in advance, and a subject who genuinely cannot accept a question’s wording has it reworked rather than sprung on them. None of this weakens the test - it strengthens it, because a subject with nothing to fear from ambiguity produces the cleanest possible charts, and a deceptive subject gains nothing from wording they helped agree.

When you book with us, question design is part of the service, not an extra: bring the situation, and the consultation turns it into a testable examination. If you already know roughly what needs asking, bring that too - it shortens the journey. And if what you have is only a knot of suspicion and no idea how to phrase it, that is more than enough to start from; turning that knot into three precise questions is exactly the craft you are paying for.
