In an oral history posted on YouTube, musician Tom Henry recounts the story of how, as a young Navy seaman, he was caught with a pound of marijuana in his locker, but escaped punishment after fooling the lie detector:
The technique Tom thought of for fooling the lie detector (dissociation) wasn’t very sophisticated. But it evidently worked against what, given the time (1966) was very likely a Relevent/Irrelevant polygraph “test.” For more on various polygraph techniques and how they can be manipulated, see The Lie Behind the Lie Detector (1 mb PDF).
Tom Henry’s story helps highlight the foolhardiness of relying on polygraph results. For more background on how Mr. Henry came to have a pound of marijuana in his locker, see his preceding video, Busted for Pot.
