Harry Potter and the Methods of Rationality discussion thread, part 27, chapter 98

Vaniver

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 98. 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, 26.

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

Most of the ideas listed so far are either much too nasty, better done with magic, or both. Mostly both. So, what contingencies could Harry procure from the world for a reasonably modest amount of money that do things he cannot just transfigure, or do by wand, and which the twins would not recognize?

First thing that comes to mind are various non-lethal drugs, since those are going into the targets body, which means transfiguration is out if you want the subject to live. So, LSD (lethal dose absurdly higher than effective dose. .which is useful if you want to dose a crowd) Tranquilizers think this fits on all counts?

Lets see, what else would it be a bad idea/impractical to transfigure. Muggle photography gear? But the twins would recognize that.

Smoke grenades. (Not subject to finite, a counter for every spell that requires you to see your target.)

Protective kit good enough to count as valid precautions for transfiguration stunts.. would break the budget given.

Id say bugging kit, but a purely mechanical recording device would be a museum piece, and cabinet size..

LSD

Dosing the water supply might well work better on wizards than on muggles. Muggles chlorinate their water supply, and even a small amount of chlorine will rapidly inactivate LSD.

Don't forget useful drugs to use on allies ratehr than enemies. Small quantity of chemical explosives.
