Another possibility is that you are a lying fed stirring the pot. For instance, a fed could point to your comment as evidence that antipolygraph.org is inciting people to break the law, which is a gambit they have used before.
All I'm saying is... if you are about to take a polygraph, or think you will in the near future: it is in your best interest to read this guide. On another note, after you read the guide and possibly benefit from it...you might find your attitude towards them changed. If the polygraph remains the de facto "lie detector", then we can all rest easy: because they are trivial to pass.
This is why a (good) defense attorney advises you against taking a polygraph if one is offered during a trial. If you pass, the case is not magically dismissed: it's useless. If you fail, you aren't automatically convicted, but the jury has their view of you negatively influenced by your failure of the test. You have nothing to gain by taking and passing one in court, but you have an undefined jury sentiment to lose should you fail.
For example, the control question I got in at least 7 examinations was the same: "Have you ever stolen anything in your life?"
When I heard the question, I did three things at once:
1) Mentally tried to divide 1717 by 3, over and over, knowing that I would not solve it and allowing that to make me anxious.
2) Increase my rate of breathing(pretend you are inflating party balloons).
3) Tense my entire body, by imagining fire ants crawling up my legs, about to reach my groin.
A few seconds later(don't wait to long), I answered "no". The examiner pauses, and asks if I have told him the truth. I confess to petty crimes such as stealing candy from my sister as a young child, and further confess I knew it at the time I answered, but was ashamed to tell him.
There will be several more control questions, and some of them(obvious ones) will be of that type(an expected lie, but not relevant to the topic of the examination). When you give the expected lies, you want to raise the baseline. When you give expected truths(such as "Are the lights on in this room?"), you want to answer normally. The end goal, is that any response your body has to a real conceived lie, should be lower than what you exhibited during the control questions for expected lies.
