Get definitive answers in Cardiff with 95% accurate P300 brain analysis.
Don't let suspicion rule your life. In Cardiff, our P300 lie detector test service provides the closure you need. By identifying whether a person holds specific 'guilty knowledge' in their memory, we provide a black-and-white result that allows all parties to finally close the chapter.
Instead of relying on sweating, blood pressure or breathing like a polygraph, P300 EEG testing looks directly at how the brain reacts to information it recognises.
When you see or hear something meaningful, your brain produces a characteristic “P300” wave. During the test we mix neutral and relevant details while our EEG system tracks this response in real time.
If someone in Cardiff claims not to know certain facts but their brain reacts strongly to those exact details, that can indicate concealed knowledge or deception. This provides a more objective basis for assessing truthfulness.
Sensors sit gently on the scalp – there are no needles or pain. The person being tested simply sits comfortably while we run a carefully structured set of sequences and record the data.

Measures brain recognition responses to key information, rather than just physical signs of stress or anxiety. This makes our P300-based lie detector service far more resistant to counter-measures.
Monitors sweating, blood pressure and breathing – all of which can be influenced by nerves, fear or simple counter‑measures. This is why many clients now prefer a modern lie detector service based on brain responses.

Our Cardiff lie detector service is built on established neuroscience, not guesswork. The P300 response has been studied for decades in laboratories and forensic settings.
The P300 is a measurable brainwave that appears around 300 milliseconds after a person recognises meaningful information. During testing, we show or read a mixture of neutral and case‑relevant items while the EEG headset measures these responses.
Unlike changes in heart rate or sweating, the P300 response is generated in the cortex – the memory and decision‑making areas of the brain. It is extremely difficult to consciously suppress or fake this response, which is why research shows up to 95% accuracy.
Our protocols are based on peer‑reviewed “guilty knowledge” and “concealed information” test designs used internationally. We are transparent about limitations and always advise Cardiff clients to see results as strong evidence, not an automatic court verdict.
