The sadder thing is that Eliezer doesn't seem particularly bothered with numbers either. The "armies" each of the generals have are mentioned to have 24 soldiers each.

24x3=72 students in the first year. This would only make sense if the size of the classes in MoR were about twice as big as in canon. But MoR has never mentioned a single non-canonical first-year student, as far as I can remember, which would imply the opposite, that the sizes of the classes must be about as big as in canon (namely about 40 students in the first year, all houses combined).

EDIT TO ADD: above comment now retracted as factually false, see comments below.

I beg your pardon. Check Ch. 30 and you should see some non-canonical first-year student cameos in Draco's army. For, may I mention, exactly that reason - I was explicitly familiar with the dilemma of the discordant Rowling statements and decided to resolve in favor of Hogwarts having around a thousand students, so that having around half the students sign up for the armies would give you 72 first-year soldiers.

Harry Potter and the Methods of Rationality discussion thread, part 9

by Oscar_Cunningham 1 min read9th Sep 2011725 comments


(The HPMOR discussion thread after this one is here.)

The previous thread is over the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread.  This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it. The latest chapter as of 09/09/2011 is Ch. 77.

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: one, two, three, four, five, six, seven, eight.  The author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.

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:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it's fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that "Eliezer said X is true" unless you use rot13.
