The key difference
A polygraph measures **physiology** (perspiration, pulse, breathing). These are reactions of the autonomic nervous system.
Red Rabbit analyzes **behavior** (facial expressions, voice, eyes, movement). These are micro-signals a person cannot consciously control.
Which is more accurate?
Both approaches have limitations. A polygraph can be fooled with controlled breathing. One can try to fool the AI with controlled facial expressions — but controlling 5 channels at the same time is practically impossible.
