My opinion is that Harry's taught enough rationality at Hogwarts that the lie will fall apart.
Not judging by everyone's reactions when Hermione was accused of murder. A select few individuals might manage to question it at best.
Now that I think about it, shouldn't some Hogwarts students and/or teachers have figured out that they should be studying Muggle science? It's possible that this was mentioned, and I've forgotten it, or that (since EY probably won't write sequels, the subject will need to be left to fanfiction of HPMOR.
It hasn't been, except for Harry's suggestion in the latest chapter. Most people, though, still haven't been exposed to any noteworthy Muggle science except individual "clever tricks" as used by Harry - nothing to compare with the obvious power of magic.
I didn't give a time frame for when Harry's lie will fall apart. :-)
I can hope that the students having learned some rationality will cause them to keep getting better at it.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 119.
Plans for next chapter release:
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
