palladias

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 97. The previous thread is at nearly 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, 17, 18, 19, 20, 21, 22, 23, 24, 25.

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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.

[...] with Moody's bright-blue eye rotating wildly in every direction, as though to signal to any possible attacker that he was On Guard and Constantly Vigilant

Why does he advertise it? Why not hide it behind an eyepatch, as a secret advantage in a fight?

You miss the point - he is still hiding it. The eye provides full 360-degree vision at all times, but few people know this, so he maintains an appearance of some level of vigilance.

This means that anyone who sees him respond quickly to a threat (i.e. evidence of vigilance) will have an immediate explanation of how he was able to do so (being vigilant), and not look beyond it to find out the extent of his abilities.

Quite well thought out, really.

He does hide it. In the part in the graveyard where he is talking to Snape while they are poisoning Riddle Sr's grave, he keeps spinning around, despite the fact that the eye lets him see 360 degrees regardless of where it is pointing. If he's escorting Potter around, everyone KNOWS he'd be on high alert, so they expect to see the thing whizzing around. Then they expect that when it isn't whizzing around, it means he can't see behind him. And when they try to exploit that, that's how he catches them.

It seems to already be widely known among magical Britain what his noble phantasm is. (Curiously, this didn't seem to be the case in canon -- the Eye doesn't even have a name there -- but Moody is still not sufficiently cautious about it there.)
