Gordon,

I have to say that I find it strange, and discordant, that on the one hand you value civilized discourse (as do I, and thanks for recognizing that, though I didn't find George's comments to you vituperative or non-substantive), yet on the other, you advocate a technique that in practice is often characterized by the polygraph examiner's abuse, distortion of the subject's words, arrogance, deception, crassness, vitriol, intimidation, and puffery.  

If it were just a pure diagnostic tool, that would be one thing, but the polygraph is used as a cudgel.  How do you reconcile this?
