No secret information is required for Harry to come to his conclusion of "So you really are his one weak point. Huh."

Available evidence:

  • Lucius is well known as a hard bastard (initially supplied by random customer, reinforced by Draco)
  • Draco is well cared for (he is healthy, very well dressed, displays no social anxieties, worships his father)
  • Draco is probably indulged or even spoiled (Draco's behaviour)
  • Draco is being groomed to be Lucius' successor and therefore his equal (very clear by this point)

From this evidence it can be reasonably concluded that Lucius loves his son.
For a hard man like Lucius, this makes Draco his likely weakest point.

Lucius is simply underestimating Harry's ability to make good use of the available information (and possibly also underestimating how much Draco has given away while trying to cultivate Harry).

EDIT: 25 Jan 2012 - I just noticed that a previous incomplete revision of this comment appeared below by accident. It is now retracted...

Nice. I like your explanation much better than mine. Keeping in mind that Lucius knows very little at this point about what Harry is like — and that Harry is only eleven! — I guess it's reasonable for Lucius to assume that such an observation by a fellow student of Draco's would require some adult tutelage.

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

(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:

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.
