Lie detector: questions
Can a phone detect lies?
No. Phones can't measure anything that shows whether someone is lying, and even real polygraphs are not reliable enough for most courts. This is a prank game: the result is random, unless the host uses the secret below.
How does the lie detector prank work?
The suspect holds their thumb on the scanner while answering. After three seconds it shows TRUTH or LIE DETECTED. Secretly, the host can decide the result.
What questions should I ask?
