WifeofAGoodGuy:  a rant is exactly what your post is.  Let's review your post:

My husband also has ADHD, and likely has mild Asperger's syndrome.*I* know that he doesn't have the same kind of affect as normal, neuro-typical people, but a 20-something polygrapher, w/ no more training than a barber, probably doesn't.

Ok, and you know the examiner was a 20-something how?  Were you there?  Did the examiner inform you he was a 20-something?  Of course not.

Also, my husband and I are both religious, and he *told them that*.Thanks to this site, I know that probably flags him for deception.You can't freaking win with these people!!!!!

Being religious "flags one for deception"?  Really???  Which religion?  Jew?  Gentile? Muslim?  Your statement is utterly ridiculous.  Why?  Because DOD regulations specifically prohibit issues of race, religion, and political beliefs from being addressed during any DOD polygraph exam.  Furthermore, federal agencies prohibit any discussion of religious topics, either during pretest or posttest.

Because of his convictions, he won't get on this site, or read anything I've downloaded, or let me try to coach him in any way.I even tried to slip in some suggestions, and he gave me the "look" and changed the subject.

This statement is more comical than ridiculous.  If you're both religious, then why are you researching this but your husband is not???  Perhaps you're both of different religions, and his condemns him to eternal hell if he researches polygraph!! ;D

And to answer your initial question, an independent review was already conducted by senior NSA polygraph supervisors.  If they did not concur, your husband would have been invited back for a retest.

Oh, and BTW, any idiot with a PhD can call himself "Doctor";  unless he is a medically-trained physician, he is not a doctor, just someone with a doctorate, like "Dr" Richardson.
