Re the rot13 bit, I called it that Qhzoyrqber xvyyrq ure based on text evidence before that was revealed, so the idea that it's Obarf has always seemed wrong to me. They can't both have done it, you know?

Arf, didn't mean to start this again, but here's my usual litany:

And if that's not as close as you can actually come to a Bayesian updating process when reading a fiction book, where the only experiment you can perform is "Wait for more chapters and then read them", I would love to learn what's legitimately closer.

I think you miss that this is a work of fiction that has an author. Think about why the author was motivated to make certain choices instead of thinking why the characters were motivated.

That is actually the other reason that I believe as I do. It seems like a much more interesting storytelling decision for my theory to be correct than for the competitor theory to be.

Comment author: 75th 09 July 2013 06:34:09PM 2 points [-]

How is it more interesting storytelling for the guy everyone thinks did it to have done it, as opposed to "Here's a puzzle and the clues to figure it out"?

Comment author: Alsadius 10 July 2013 08:31:02AM 1 point [-]

Because it was a puzzle for the first what, 80 chapters? We're getting close to the end of the story as of about two arcs ago, it's time for puzzles to get solved. it's not an interesting enough puzzle to justify a double twist, IMO.

Comment author: 75th 10 July 2013 04:30:11PM 1 point [-]

You think it's not an interesting puzzle because you think it's not a puzzle at all. :) And wouldn't it only be a double-twist if Dumbledore did do it? If Amelia Bones did it it would just be a single twist.

Comment author: Alsadius 12 July 2013 07:26:50AM *  2 points [-]

Baseline assumption: Team Death Eater is slandering Dumbledore when they claim he burned Narcissa Malfoy alive.

Twist: Nope, Dumbledore actually did it.

Double Twist: Or it was some random lady who used the word "burn" once. You know, whatever.

One of these twists is revealing of important information about a main character, future motivation for interesting developments(Harry being forced to choose between Draco and Dumbledore over the promise, or Draco having to forgive his mother's murderer), a subversion of our expectations, and is reasonably predictable from evidence dropped in advance. One of them is irrelevant and a complete cop-out of all the character development built into the original twist. Take a guess which one I assume is more likely to be true.

Amelia killing Narcissa would be the sort of thing M Night Shyamalan would write.

If that were indeed an accurate summary of the situation, I would agree with you. I did agree with you, when that was the only potential clue I knew of. All three major clues would be circumstantial in real life, but when you step out a level and see that Eliezer writes this story, choosing every word we read, it's clear that he wants us to figure out that Amelia has something more to do with Narcissa's death.

One of these twists is revealing of important information about a main character

It's just as important if Dumbledore didn't do it as it is if he did; it's another piece of evidence that he's not a huge evil hypocrite. Which many HPMoR readers seem to need.

future motivation for interesting developments(Harry being forced to choose between Draco and Dumbledore over the promise, or Draco having to forgive his mother's murderer)

I think it'll be pretty interesting when Harry finds out that Amelia did it; Amelia was going for painful revenge, while Harry is already hemming and hawing over whether Dumbledore deserves to be an enemy if he did do it. Harry is much more likely to declare Amelia his enemy, and Amelia is much more likely to declare Harry her enemy.

a subversion of our expectations

Sounds to me like Amelia would be the biggest subversion of your expectations! Given the several conversations I've had on this topic, I'm pretty sure that Amelia's guilt will be a subversion of most people's expectations. In fact, I and possibly pedanterrific may be the only ones in the entire readership whose expectations aren't subverted.

and is reasonably predictable from evidence dropped in advance.

I really don't understand why everyone thinks the three clues I identified are worth so much less than the clue-and-a-half we have about Dumbledore.

One of them is irrelevant and a complete cop-out of all the character development built into the original twist. Take a guess which one I assume is more likely to be true.

Amelia killing Narcissa would be the sort of thing M Night Shyamalan would write.

And this is why I didn't actually mean to start this conversation again; this is the second or possibly third time that I've pushed someone to declare Eliezer a bad writer if my hypothesis proves true, who will now actually feel that way when it is proven true, where they probably would have just said "Huh!" before, or maybe even thought it was cool.

I just don't get it. I don't understand people's reluctance to believe this, to step outside the text and realize that these are purposely written clues. Maybe it's because I'm acting all certain again; maybe perceived overconfidence causes bad reactions in people even with all the supporting evidence, not only without it.

Amelia Bones isn't a member of the Order of the Phoenix.

Emmeline wasn't a member of the Order of the Phoenix any more, they had disbanded after the end of the last war. And during the war, she'd known, they'd all known, that Director Crouch had quietly approved of their off-the-books battle.

Director Bones wasn't Crouch.

[...]

"That depends," Amelia said in a hard voice. "Are you here to help us catch criminals, or to protect them from the consequences of their actions?" Are you going to try to stop the killer of my brother from getting her well-deserved Kiss, old meddler? From what Amelia heard, Dumbledore had gotten smarter toward the end of the war, mostly due to Mad-Eye's nonstop nagging; but had relapsed into his foolish mercies the instant Voldemort's body was found.

One wonders why she would even know about it at all, if she had nothing to do with it.

Well, I think Lucius probably made sure a long time ago that everyone knew what Dumbledore (supposedly) said to him. I didn't get the feeling from that scene in the Wizengamot that Dumbledore-killing-Narcissa was any kind of a secret idea that people were just then finding out about.

This does rather change my view of some of the peripheral details, though. Previously, one possibility I pictured was Dumbledore restraining Amelia from her vengeance until Aberforth died, then relenting. I knew Amelia Bones wasn't in the OotP, and I knew she felt distaste at Dumbledore's softness, but somehow I never completely drew the conclusion that she wouldn't care one whit about what Dumbledore said or thought, and therefore probably wouldn't have cared if he had tried to restrain her.

Perhaps more likely, then, is the other way I pictured it: that Amelia couldn't get to Narcissa by herself, and after Aberforth's death, Dumbledore actively approached Amelia and said "Okay, I'm ready to help. I'll be the ward-breaker, you do the deed."

Whoops, looks like you're right, the accusation was public knowledge:

Father's own allies didn't believe him after Dumbledore just denied everything in public

Comment author: 75th 09 July 2013 06:38:53PM *  0 points [-]

Dumbledore's motive is almost certainly stronger than Amelia's.

Which is why I think it a significant possibility that Dumbledore helped in some way.

Any of those defenses might be sufficient for a single clue, but you have to take the clues together. Three successive clues (plus her character) pointing to Amelia, and only some words spoken to Lucius that we never saw pointing to Albus (and everything else we know of his character pointing away from him, though I know some would argue that), increase the probability of Amelia's guilt quite a bit more than linearly.
