I think your decision to refuse the polygraph is a wise one. Should you need to justify your decision in court, you can explain that since the time you initially expressed your willingness to take a polygraph, you have learned about the unreliability of polygraphy. In doing so, feel free to mention this website. Chapter 1 of our e-book, The Lie Behind the Lie Detector (and the sources cited therein) provides a thorough debunking of polygraphy. You may wish to provide the court a printout.

Other documentation you can cite in support of your decision to refuse the polygraph includes Professor William G. Iacono's article, "Forensic 'Lie Detection': Procedures Without Scientific Basis":

If your lawyer were to contact former FBI scientist and supervisory special agent Dr. Drew C. Richardson through this website, you may also obtain a customized and signed copy of his "Evaluation and Opinion of CQT Polygraphy:

It is not "being uncooperative with the process" to refuse a polygraph. Rather, it's being rational. Those who would rely on such pseudoscientific nonsense as polygraphy in such a serious matter as this are guilty of exercising extremely poor judgment.

i was accused of a crime and went down to the station for interrogation... I answered there questions and asked if im willing to take a polygraph..i responded " sure no problem" but did not sign anything,,, they will be calling me in a week. Now i see taking the test is not in my best interest. WHat do i tell them when they call and ask for me to come down? I skimmed through the book but ran into a conflict .....

Complete Honesty
A second approach is to be completely honest with your polygrapher.
Tell him that you know the lie behind the lie detector. Explain to
him that you understand that the true purpose of the “stim test” is
to dupe you into believing in the validity of polygraphic lie detection.
Tell him that you understand the trickery behind “control” question
“tests”—whether probable- or directed-lie. Explain that you understand the difference between “control,” relevant, and irrelevant questions and that you have studied and know how to employ polygraph
countermeasures. Give him a printout of this book to prove it in a
way that he will not be able to later deny. Explain to him that you
are not a suitable candidate for polygraphic interrogation, and request
that your polygraph “testing” be waived.

then it says


If you’ve been polygraphed before, you can mention it. But don’t
tell your polygrapher that you’ve read this book or that you’ve
done research on the Internet and visited such websites as
AntiPolygraph.org! If you admit to having researched polygraphy,
your polygrapher will become suspicious. His next questions may
well be, “Why have you educated yourself so much about the polygraph? Do you have something to fear from it?” Instead, provide a
general answer to his question about what you know about polygraphy,"


what do i do?
