Before you upload: how to read results
Most people tell the truth most of the time. Research shows roughly 60% of people tell no lies on a given day, and a small minority tell the majority of lies. This analysis looks for signals, not proof, and should be read against that baseline.
- There is no single gesture, expression, or vocal cue that reliably indicates lying.
- What someone says (content, detail, verifiability) matters more than how they say it.
- Even trained humans detect deception at ~54% accuracy — barely above chance.
Do NOT use this tool for
- Hiring, firing, or any employment decision (prohibited by EPPA in most US employment contexts)
- Law enforcement, border control, or immigration screening
- Analyzing minors (under 18)
- Analyzing any person who has not given informed consent
- Insurance claims, custody disputes, or legal proceedings as sole evidence
Intended use: self-analysis for communication coaching and research. This is not a lie detector.
Known validity limits
- Primarily validated on English-speaking, Western, neurotypical adults — may be unreliable outside that population.
- Neurodivergent individuals (autism, ADHD, anxiety) may trigger false positives.
- Cultural differences in communication norms can be misread as incongruence.
- Accuracy range in ideal conditions: 60-75% (peer-reviewed research). Real-world accuracy is lower.
