they arent scientific at all, in fact, a liar that isnt all that skilled can beat them, and as far as i know, a spy must be a very skilled liar. i know local law enforcement requires this scam for employment, but i find it hard to believe that the feds would use it to catch spies, but then...the feds did start a war in the name of national security, meanwhile both borders are scarily un secured........

They NEVER used the polygraph to catch spies. They use polygraph EXAMINERS to catch spies. The machine only intimidates people. The person BEHIND the machine is the lie detector.

Counterintelligence polygraphs are still required for employment in some federal agencies such as the CIA, FBI, and DoD. A quick look at employment criteria at these agencies and others will confirm this for you.

No they use eye scans to see if someone is telling a lie.
