Electric Machine To Tell Guilt Of Criminals

The “psychometer” described in this article works in the same way as modern polygraph machines.

But the technology is still far from being “perfected so as to be infallible.” You needn’t look hard to find harsh criticism of lie detectors including tips on how to beat one. In an episode of Penn & Teller’s Showtime program Bullshit, they talked to “people whose lives were ruined by faulty lie detector results.”
