Several years later, he admitted to me that he had committed the theft. Another friend was accused of a burglary and "failed" the polygraph, even though he was with me, 40 miles away when the burglary was committed. The polygraph has validity equal to voodoo.

Note that the polygrapher was in a position to know whether or not the author had taken the money before the polygraph was administered. A hand signal or a silent page from the polygrapher's partner could have tipped him off. It's doubtful that the polygrapher, knowing that he's polygraphing a writer, would leave such things to chance. Yoffe's anecdotal tale is no substitute for a controlled, double-blind experiment, and it's not safe to make any inferences about the difficulty of fooling the polygraph based on it.

I had heard it (it was early in the morning and I was asleep). I didnt think much of it. The police asked me to take a lie detector test. I complied and they gave me a polygraph test. They started asking me questions trying to implicate me in robbing my neighbor. Totally ridiculous. At the end of it the officer who gave me the test said that I had failed. He said I had either done it, or knew who had done it. I told him his technology was faulted and I am only taking the test because the police had asked me and I wanted to cooperate in helping as much as they wanted me to. Take it for what its worth. They dont work. That was 4 years ago, maybe they have improved. Someone kicked down my neighbors door one day. I had heard it (it was early in the morning and I was asleep). I didnt think much of it.
