Without judging the validity of the poly itself (I concur, it's garbage), it's also not the sole basis of any decision, and the actual people doing the investigation build a case to show that you have lied about something, because you an appeal their decisions to a judge. It's not just 'meh, the line wiggled so no clearance for you'.
You'll forgive me if I have no faith in a system that uses polygraphs as input, has inspired leakers like Snowden, and has come up "courts" like the FISA "court".
Being told by the IC it will be reviewed by a judge is not reassuring.
