No idea the conversation I'm jumping into here but on the 20/80-40/60 thing, it wouldn't necessarily be amiss to think this includes much broader subjects.
Gods, aliens, inter-dimensional beings etc. Could be covering up the fact that evil already won and we're living in hell. Or Rick/Morty fags get their Universe-in-a-battery reality.
Paraphrasing Q: "Some things have to remain hidden, for humanity".
The vast swathes of information that could qualify under that hidden % could be, literally, anything, of any alternate subject. Just something to bare in mind.
