Your argument supposes that Harry - at age 11 - has mental defenses better than Flamel at age >600.
It's almost as if Harry is a mental clone of the most powerful Legilimens in recorded history.
Seriously, no.

"Perenelle has lived this long by knowing her limitations," said Professor Quirrell. "She does not overestimate her own intellect, she is not prideful, if that were so she would have lost the Stone long ago. Perenelle will not try to think of a good Mirror-rule herself, not when Master Flamel can leave the matter in Dumbledore's wiser hands...
Eh.. Voldemort is a legimens. But he isn't an unusually good one at all. He actively dislikes actually reading peoples minds. He simply had a very impressive talent for entirely non-magical cold reading and inference. The wizarding public heard tales of that, and in the same way they failed to consider "hidden broomstick enchantments!" credited him with scary superpowers he didn't actually have.
This is an inference from the text, but a high probability one. - However, it is also stated outright in the text that Harry's mental defenses are nothing special. He's an occlumens, but according to his teacher in that art, who bloody well should know, not a perfect one.
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 116.
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.)
