Two things, one: being more difficult to disarm isn't really as much of an advantage as it might seem. Remember, we have some idea of how magical combat works in MoR, and it seems to revolve around layers of active and passive defenses - during Bahry One-Hand, veteran Auror, v. Polyjuiced!Quirrel, the description went
According to the Defense Professor, the essential art of dueling consisted of trying to put up defenses that would block whatever someone was likely to throw at you, while trying in turn to attack in ways that were likely to go past their current set of defenses. And by far the easiest way to win any sort of real fight - Professor Quirrell had said this over and over - was to shoot the enemy before they raised a shield in the first place, either from behind or from close enough range that they couldn't dodge or counter in time.
If telekinesis-type spells (Accio, Expelliarmus, Wingardium Leviosa) are relatively easy to shield against, fights would tend to end by incapacitation rather than disarming whether you had a wand or not.
And two: interestingly, 'accidental magic' (used by wizarding children before they get their wands, generally in times of high emotion) is actually somewhat more impressive than what just-got-their-wands first years can do. Example: before he went to Hogwarts, canon!Harry once managed to get from standing on the ground to standing on the roof of his school without quite being aware of how he did it - the text seems to imply some kind of teleportation / Apparation, but it could have been self-levitation - either way, much more impressive than anything he could do for a while afterwards.
I've been thinking about magical training that doesn't look like conventional schooling, and training accidental magic would be an interesting place to start. Would it be like learning jazz? Improv? A soft martial art?
(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 fanfiction.net 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:
