Harry hasn't won consistently. He's lost plenty of mock battles, and while he sometimes gets his way against adults, he's sometimes thwarted. Harry also does have a couple advantages that can't readily be replicated by other characters, namely his technological and scientific savvy, and the True Invisibility Cloak, and the time turner which can't be replicated by most of his opponents.
Eliezer wrote ages ago that he gets people complaining that Harry wins too often and isn't sufficiently challenged, and people complaining that he loses too often and doesn't accomplish much, and considers himself to be doing his job properly if he's at least getting similar amounts of each kind of complaint.
Edit: New thread posted here.
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 86. The previous thread has long passed 500 comments.
There is now 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.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
