Polygraphs are intimidation devices with no scientific merit. They don't work. By making people believe that they do work, sometimes interrogators are able to get people to admit things they otherwise wouldn't.
Polygraphs are not admissible as evidence in court and civilian employers are not allowed to administer them to employees. Regardless, the US Government still uses them for security clearance.

- marshmallow_12 6y agoyour answers and the fact that no one is defending polygraphs indicates to me that i'm not far off the mark. In which case, why on earth is the FBI messing around with it? My conclusion, corroborated by this story is that they are not so professional as they would like you to think. This is compensated, probably with interest, by being very heavy handed. But surely that is no way to run a large agency.
- boomboomsubban 6y agoThe FBI is nowhere near as professional as people are led to believe. The lie detector test isn't even unique, we are not even a decade removed from evidence showing nearly all their forensic techniques were utter shams.
- pure_simplicity 6y agodo you have some resources on this?
