You just can't tell.
The linked article by Elizer Yudkowsky is straight up wrong for the following reasons:

But bonus points to you if you reject this argument because you shouldn't accept my authority any more than you should accept his.

New chapter!
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 102.
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.
