P300 EEG vs Polygraph — Accuracy Comparison
Independent research consistently shows P300 EEG brain-wave analysis outperforms traditional polygraph across every key measure.
Sources: Farwell & Donchin (1991), Rosenfeld et al. (2008), peer-reviewed EEG literature.
What the Readings Actually Look Like
The P300 brain-wave spike is a single, unmistakable response. Polygraph produces four overlapping signals full of noise — see why P300 EEG results are so much clearer to read.
P300 EEG — Brain Wave Response
✓ One clear spike — unambiguous result
Polygraph — 4 Overlapping Signals
✗ Noisy, subjective, open to interpretation

"We had been together for eleven years when trust broke down over a specific incident. The P300 couples test in Stirling confirmed both our accounts were honest and the incident had been a misunderstanding. We're still together."

"My partner had been messaging an ex for months and claimed it was innocent. The P300 test in Newport confirmed deceptive responses around the nature of those messages. The examiner explained the results in plain language I could understand."
"We had both become suspicious of each other simultaneously which made things impossible. The P300 couples test in Wigan cleared both of us in the same session. The examiner handled the unusual situation professionally and without judgement."
"I had started to believe I was imagining things after months of dismissal. The P300 infidelity test in Harrogate confirmed I was not imagining anything. The examiner's calm delivery of a difficult result was handled with real sensitivity."
"My husband agreed to the P300 test in Dundee as a gesture of commitment after a period of distance between us. He was completely cleared. The result repaired something that six months of reassurance from him alone hadn't managed."
"I used the P300 unfaithful partner service in Paisley after a period of unexplained behaviour that had gone on for most of the year. The results confirmed my concerns were not unfounded. Hard day, but the right decision."

"The P300 test in Livingston proved my wife had been faithful despite what a mutual friend had suggested. The examiner was brilliant at explaining the results clearly. I owe my wife an enormous apology and this test helped me realise it."

"My partner kept changing their story about a weekend I hadn't been invited to. The P300 test in Swindon confirmed deceptive responses throughout the session. The examiner helped me process a very difficult result with real professionalism."
"My wife had been spending time alone with a neighbour regularly. The P300 test in Motherwell confirmed that relationship had become physical. I had suspected it for six months and finally having certainty allowed me to move on properly."
"We had rebuilt our relationship after a previous infidelity and new doubts were emerging. The P300 test in Gloucester proved my partner had stayed faithful this time. That result was the foundation we needed to finally trust each other again."

"My fiancée and I both took the P300 test in Inverness before our wedding as a mutual trust exercise. Both results were clear and the process brought us closer rather than creating tension. Highly recommend it for any couple with unresolved doubts."

"My partner came to the P300 test in Walsall voluntarily after I expressed serious doubts. They were proved completely faithful. The way the examiner explained the results made accepting them straightforward for both of us."

"My partner denied cheating for eight months despite evidence to the contrary. The P300 test in Gateshead confirmed deception in every relevant section of the test. The examiner was thorough, professional and kind throughout the whole session."
"I arrived at the testing centre in Mansfield not knowing what I wanted the result to be. The P300 showed my partner had been faithful. Whatever complicated feelings I had going in, walking out with that result felt like a genuine second chance."
"Years of uncertainty ended in one afternoon at the P300 testing centre in Keighley. The result confirmed a long-standing affair that had supposedly ended. Having a written scientific result rather than a promise finally gave me the confidence to act."
