Deception detection is the process of determining whether someone is being truthful — using science, not guesswork.
When someone lies, their body and brain respond in measurable ways. For over a century, polygraph machines tried to catch those responses by tracking heart rate, blood pressure, and sweating. The problem is those signals are triggered by stress and anxiety — not deception itself. A nervous truthful person fails. A calm liar passes.
Modern deception detection takes a fundamentally different approach. Instead of measuring stress, our P300 EEG system measures what your brain recognises. When your brain encounters information it already knows — a name, a place, a detail from an event — it produces an involuntary electrical spike. You cannot suppress it, fake it, or train it away. That's what makes P300 EEG deception detection 95% accurate, compared to roughly 65–70% for a traditional polygraph.
We provide professional deception detection across Antrim and the wider Antrim and Newtownabbey area for relationships, family disputes, workplace accusations, corporate investigations, and legal matters. Testing is non-invasive, takes around 90 minutes, and starts from £499. We travel to you or you can visit one of our testing venues.
The P300 is a specific electrical signal your brain produces when it recognises something it already knows. Here's exactly how we use it.
Roughly 300 milliseconds after your brain sees a stimulus it recognises, it produces a measurable spike of electrical activity called the P300 event-related potential. This was first documented in peer-reviewed neuroscience research in the 1960s and has been studied extensively ever since. The P300 is completely involuntary — it happens before conscious thought. Your brain fires it whether you want it to or not.
You wear a lightweight BrainBit EEG headband that sits on your forehead and behind your ears — no wires, no straps, no chest sensors. You sit in front of a screen and are shown a series of words, images, or statements. Some are relevant to the case. Some are irrelevant controls. All you do is watch.
Our 8-channel EEG system records your brain's response to each stimulus in real time. When your brain recognises something relevant — a person's name, a location, a detail you claim not to know — the P300 spike appears across multiple channels. When the stimulus means nothing to you, the signal stays flat. That recognition vs no-recognition pattern is what determines the result.
Polygraph countermeasures work because they target voluntary body responses — you can control your breathing, clench your toes, or bite your tongue to disrupt readings. The P300 response is neurological and involuntary. There is no muscle to clench, no breathing pattern to change, and no mental technique that suppresses it. Published research by Farwell & Donchin (1991) and Rosenfeld et al. (2008) consistently shows detection rates between 90% and 98% in controlled blind testing.
Within the hour of testing, you receive a detailed 8-page forensic report covering the raw EEG data, P300 spike analysis for each question, deception scoring, and a clear truthful or deceptive determination. The report is suitable for solicitors, employers, HR departments, or personal use. Expert testimony is available on request.
Independent research consistently shows P300 EEG brain-wave analysis outperforms traditional polygraph across every key measure. Here's how the two methods compare for clients in Antrim.

P300 EEG measures an involuntary brain response directly. A polygraph measures stress and asks an examiner to interpret it — which is why the two produce different kinds of finding.
Polygraph results can be manipulated with breathing or muscle techniques. P300 brain-wave responses cannot be consciously controlled.
No chest straps, blood pressure cuffs or finger sensors. Just a lightweight headband — making results in Antrim more reliable and comfortable.
The P300 brain-wave spike is a single, unmistakable response. Polygraph produces four overlapping signals full of noise. See why P300 EEG results in Antrim are so much clearer to read and harder to dispute.
P300 EEG — Brain Wave Response
✓ One clear spike — unambiguous result
Polygraph — 4 Overlapping Signals
✗ Noisy, subjective, open to interpretation
Illustrative waveforms based on published EEG and polygraph signal characteristics.
A traditional polygraph straps sensors to your chest, fingers, and arm — measuring sweat, breathing, and blood pressure while you sit in stress. Our P300 EEG test uses a single lightweight headband that reads brain activity directly. No discomfort, no intimidation, and it's over in under 90 minutes.
Every P300 EEG test includes a detailed 8-page forensic report — covering raw brain-wave data, P300 spike analysis, and a clear truthful or deceptive determination. Delivered within the hour. Swipe through example pages below.

The formal name for what we run is a Concealed Information Test, or CIT — known in older literature as the Guilty Knowledge Test. The distinction matters, because it is what separates this from a polygraph and it is worth understanding before you book anything.
A polygraph asks whether you are lying. A CIT asks something narrower and far more answerable: does this person recognise information that only someone involved would know? You are shown a sequence of items, most of them irrelevant, with the critical detail hidden among them. If you recognise it, your brain produces a P300 — an event-related potential appearing roughly 300 milliseconds after the stimulus, before any conscious decision to conceal it is possible.
This is the oddball paradigm, and it is one of the most replicated findings in cognitive neuroscience. The response is not to deception. It is to recognition. That is why rehearsal, composure and confidence make no difference to the result — there is nothing to perform.
A CIT only works when there is genuine concealed information to test against — a specific detail, known to the person involved and not to anyone else. That makes it powerful for theft, fraud and event-specific questions, and unsuitable for vague ones. We will tell you at enquiry stage if your case in Antrim is not a fit, rather than take a booking that cannot produce a meaningful result.
No credibility assessment method is free of error, and any provider claiming otherwise is overselling. An accuracy figure describes performance across a population, not a guarantee about one result. Where the base rate matters — how likely deception was in the first place — we say so in the report rather than leaving you to infer it.
Every finding we issue states the protocol used, what was measured, and the limits of what it establishes. That is the difference between a documented result and a verdict.
