This isn't how you're supposed to play with paradoxes.
I laid awake in the night, grinning a coyote grin at the ceiling.
Dr Glass rolled over, politely explained that my grin was so loud he could hear it, and demanded an explanation.
I explained the Bedtime Paradox: "If Pinocchio says 'this next statement will cause my nose to grow two inches,' then what happens to his nose?"
Dr Glass sighed wearily, scraped himself together into a slightly more conscious state, and produced a preliminary lecture outline on the perennially interesting topic of "precision vs accuracy," but I cut him off.
"Nope! It's better than that. The question is: does Pinocchio's nose know what he knows?" I illustrated this with my "DID YOU GET THE PUN DID YOU SEE WHAT I DID THERE" face, which is even more horrifying in the dark.
"Basically," I lectured, "If we're being utterly logical and sticking to the confines of the story, Pinocchio's nose should only grow if he explicitly contradicts external evidence that he knows to be true, for the purposes of deceit. Unfortunately, there's a lot that Pinocchio just doesn't know, and he probably has lots of beliefs that aren't based on evidence. In any case, the paradox isn't particularly airtight; presumably Pinocchio already has allowances for rhetoric, sarcasm, anxiety, accurate description of feelings, etc.
"If Pinocchio's nose only knows what Pinocchio knows, then all that matters is that Pinocchio believes or doesn't believe in what he's saying, and it all comes down to questions of knowledge, intent and tone. If this is how we're playing it, Pinocchio wouldn't be able to get answers to questions like "Do I love her?" by making yes/no statements (I love her / I don't love her) and watching his nose, because he doesn't actually know, and neither does his nose. By making a claim about what his nose will do, he's practicing levels upon levels of self-deceit, so who knows what his nose thinks of that?"
"However," I went on gloatingly, "The paradox WOULD be truly mindblowing if Pinocchio's nose knows what Pinocchio does NOT know."
"If Pinocchio's nose knows what Pinocchio himself doesn't know, then his all-knowing nose grows when Pinocchio contradicts any absolute truth. This would truly be a paradox - and it would be invaluable. He would be our only accurate lie detector. One could distill one's research into a yes/no question, then ask Pinocchio if it was true - even if he didn't have the faintest idea about particle physics or nanodiamonds, he'd be able to confirm or deny your findings. Put the question to him properly and he can detect criminals, predict natural disasters, and pick the best politician for the job."
I took a deep breath. "We're going to find that little fucker, hold him upside down and shake him until the evidence falls out."
