Types of Cheating Partner Tests in Cardiff
Different relationships need different kinds of cheating partner testing. We tailor each lie detector test in Cardiff to your exact situation.
Single-Partner Cheating Test
The most common option in Cardiff. One partner undergoes a targeted P300 EEG infidelity test focused on cheating, affairs and secret contact with other people.
- Ideal when you have strong suspicions about one partner
- 3–5 focused questions on sexual or emotional affairs
- Clear yes/no outcome to help you decide what to do next
Couples & Repeat Testing
- Couples Testing in Cardiff – both partners tested to rebuild trust
- Follow‑Up Tests – for ongoing concerns or new incidents
- Online Cheating Tests – focused on dating apps, sexting and messaging
- Historical Infidelity Tests – exploring behaviour earlier in the relationship
Every cheating partner test in Cardiff is designed with your situation and questions in mind, not a one‑size‑fits‑all checklist.
No Wires. No Straps. Just a Headband.
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.
Right: P300 EEG – minimal, non-invasive headband.
How Accurate Is a P300 EEG Lie Detector Test?
The science is clear — P300 brainwave testing is in a different league to the traditional polygraph.
P300 EEG: 90–95% Accuracy
The P300 response is an involuntary brainwave fired when the brain recognises something it already knows. You cannot suppress it. You cannot fake it. Peer-reviewed studies consistently report accuracy between 90% and 95% — making it the most reliable method available to private clients in Cardiff.
Polygraph: ~60% Accuracy
The polygraph measures sweat, heart rate and breathing — all of which are heavily influenced by anxiety, nerves, medication and deliberate counter-measures. Independent research puts polygraph accuracy as low as 60%, meaning roughly 4 in 10 results may be wrong. It is not admissible in UK courts for this reason.
Why does P300 accuracy hold up? Because it measures memory recognition in the brain — not how nervous you feel. A guilty person's brain fires a characteristic 300-millisecond response when it encounters information only they would recognise. An innocent person's brain simply doesn't. Anxiety, medication and nerves cannot change this response.
P300 EEG vs Polygraph — See the Difference
This is why Cardiff clients choose P300 brainwave testing over a traditional polygraph. One produces a clean, unmistakable scientific signal. The other produces noise.
P300 EEG Brain Response
Clean spike at 300ms — recognition confirmed. Involuntary. Cannot be faked.
✓ One clear, measurable response. Scientific. Objective. 90–95% accurate.
Traditional Polygraph Reading
Chaotic stress signals — sweat, heart rate, breathing. Anxiety looks identical to deception.
✗ Noisy, subjective, ~60% accurate. Innocent people fail. Guilty people pass.
The P300 spike is a neurological fact — not an interpretation. When the brain recognises information it shouldn't know, it fires. Every time. No amount of nerves, medication or counter-measure training can stop it. That is why clients in Cardiff are choosing P300 EEG over the polygraph.
Lie Detection Accuracy Compared — Cardiff
Peer-reviewed research accuracy rates for each method. The difference is not subtle.
Accuracy figures based on published peer-reviewed research. P300 EEG data sourced from Farwell & Donchin (1991), Rosenfeld et al., and subsequent independent replication studies.
