Has any news outfit or other organization ever conducted a sting to expose the fraud of polygraphy?  It wouldn't be incredibly difficult.  A news magazine posing as a government branch could hire a well known polygrapher to detect who stole some money or leaked top secret info or committed some other crime.  However, unknown to the polygrapher, no real crime has been committed.  The people taking the tests are coached actors, not real government employees.  Most use standard counter measures on control questions.  One person does just the opposite.  He uses those measures on the real questions in play "did you steal?" or "did you leak?", the idea being to create a false positive.  

Then when they get the false positive, the news magazine runs the story, showing how easy it is for false positives to happen.  

Anything like this been done? 

Thanks, that's a revealing vid.

Actually, polygraphy hasn't changed a lot in the past 25 years. While most polygraph instruments nowadays are computerized, the same physiological responses are being recorded and the same old techniques are being used.

While it's not quite the same as CBS 60 Minutes' classic exposé, see Harmon Leon's article, "Bullshitting the Lie Detector," wherein he recounts the prank he played on American Polygraph Association past president Ed Gelb and the producers of his show, Lie Detector:
