The Academy researchers even provided a pertinent example for the Feds. Given the modern polygraph's strengths, the machine could uncover 8 out of 10 spies working at, say, a national atomic laboratory with 10,000 hypothetical employees. Sounds good, but the detection comes at the price of finding 1,600 innocent employees guilty of spying. While about 8,400 good employees would pass the test, 1,600 careers would be ruined.
