Crank Plain-English Summary

In simple terms, this Crank study shows that our P300 EEG system can reliably tell the difference between people who recognise important information and those who do not. This is the same scientific principle we use in our P300 lie detector tests in Crank.

Instead of relying on breathing, heart rate or sweating like a traditional polygraph, the P300 method measures how the brain reacts when it sees meaningful details. In this controlled Crank research, the BrainBit EEG system reached 95.2% accuracy compared with only 48% for polygraph equipment – a major difference for any investigation or lie detection scenario.

These results provide a strong scientific foundation for using EEG-based lie detection in Crank, particularly for cases where objective, research-backed evidence is important.
