From what I've read about it, it works to some extent as long as people believe in it. They want to get their clearance and believe cheating could be detected, so they tend to be more truthful. It's based on intimidation and observation. The examination starts when you enter the building and stops when you leave it.
- dev_dull 8y agoSomething that tells the truth inconsistently and nondeterministically sounds worse for our society than just asking the question under oath.
- droithomme 8y agoIt's not inconsistent though. It's never caught a single spy. So it's got a 100% false negative rate. That's very consistent and reliable.
