2. How Accurate Are Polygraph Tests?

3. Polygraph vs EyeDetect: Which Is Better?

Both technologies are highly effective, but for forensic-level certainty, they are best used together. Polygraph testing measures physiological stress responses, while EyeDetect analyses cognitive load. Cross-verifying results makes deception almost impossible to hide.
