Eliezer Yudkowsky - Harry Potter and the Methods of Rationality

Harry quickly took his leave.

Hermione Granger had worried she was turning Bad.

The difference between Good and Bad was usually easy to grasp, she'd never understood why other people had so much trouble. At Hogwarts, "Good" was Professor Flitwick and Professor McGonagall and Professor Sprout. "Bad" was Professor Snape and Professor Quirrell and Draco Malfoy. Harry Potter... was one of those unusual cases where you couldn't tell just by looking. She was still trying to figure out where he belonged.

But when it came to herself ...

Hermione was having too much fun crushing Harry Potter.

She'd done better than him in every single class they'd taken. (Except for broomstick riding which was like gym class, it didn't count.) She'd gotten real House points almost every day of their first week, not for weird heroic things, but smart things like learning spells quickly and helping other students. She knew those kinds of House points were better, and the best part was, Harry Potter knew it too. She could see it in his eyes every time she won another real House point.

If you were Good, you weren't supposed to enjoy winning this much.

It had started on the day of the train ride, though it had taken a while for the whirlwind to sink in. It wasn't until later that night that Hermione had begun to realize just how much she'd let that boy walk all over her.

Before she'd met Harry Potter she hadn't had anyone she'd wanted to crush. If someone wasn't doing as well as her in class, it was her job to help them, not rub it in. That was what it meant to be Good.

And now...

...now she was winning , Harry Potter was flinching every time she got another House point, and it was so much fun, her parents had warned her against drugs and she suspected this was more fun than that.

She'd always liked the smiles that teachers gave her when she did something right. She'd always liked seeing the long row of check-marks on a perfectly answered test. But now when she did well in class she would casually glance around and catch a glimpse of Harry Potter gritting his teeth, and it made her want to burst into song like a Disney movie.

That was Bad, wasn't it?

Hermione had worried she was turning Bad.

And then a thought had come to her which wiped away all her fears.

She and Harry were getting into a Romance! Of course! Everyone knew what it meant when a boy and a girl started fighting all the time. They were courting one another! There was nothing Bad about that.

It couldn't be that she just enjoyed beating the living scholastic daylights out of the most famous student in the school, someone who was in books and talked like books, the boy who had somehow vanquished the Dark Lord and even smushed Professor Snape like a sad little bug, the boy who was, as Professor Quirrell would have put it, dominant, over everyone else in first-year Ravenclaw except for Hermione Granger who was utterly squishing the Boy-Who-Lived in all his classes besides broomstick riding.

Because that would have been Bad.

No. It was Romance. That was it. That was why they were fighting.

Hermione was glad she had figured this out in time for today, when Harry would lose their book-reading contest, which the whole school knew about, and she wanted to start dancing with the sheer overflowing joy of it.

It was 2:45pm on Saturday and Harry Potter had half of Bathilda Bagshot's A History of Magic left to read and she was staring at her pocket watch as it ticked with dreadful slowness toward 2:47pm.

And the entire Ravenclaw common room was watching.

It wasn't just the first-years, news had spread like spilled milk and fully half of Ravenclaw was crowded into the room, squeezed into sofas and leaning on bookcases and sitting on the arms of chairs. All six prefects were there including the Head Girl of Hogwarts. Someone had needed to cast an Air-Freshening Charm just so that there would be enough oxygen. And the din of conversation had died into whispers which had now faded into utter silence.

2:46pm.

The tension was unbearable. If it had been anyone else, anyone else, his defeat would have been a foregone conclusion.

But this was Harry Potter, and you couldn't rule out the possibility that he would, sometime in the next few seconds, raise a hand and snap his fingers.

With sudden terror she realized how Harry Potter might be able to do exactly that. It would be just like him to have already finished reading the second half of the book earlier...

Hermione's vision began to swim. She tried to make herself breathe, and found that she simply couldn't.

Ten seconds left, and he still hadn't raised his hand.

Five seconds left.

2:47pm.

Harry Potter carefully placed a bookmark into his book, closed it, and laid it aside.

"I would like to note for the benefit of posterity," said the Boy-Who-Lived in a clear voice, "that I had only half a book left, and that I ran into a number of unexpected delays -"

" You lost! " shrieked Hermione. "You did! You lost our contest! "

There was a collective exhalation as everyone started breathing again.

Harry Potter shot her a Look of Flaming Fire, but she was floating in a halo of pure white happiness and nothing could touch her.

" Do you realize what kind of week I've had? " said Harry Potter. "Any lesser being would have been hard-pressed to read eight Dr. Seuss books!"

" You set the time limit."

Harry's Look of Flaming Fire grew even hotter. "I did not have any logical way of knowing I'd have to save the entire school from Professor Snape, or get beaten up in Defense class, and if I told you how I lost all the time between 5pm and dinner on Thursday you would think I was insane -"

"Awww, it sounds like someone fell prey to the planning fallacy. "

Raw shock showed on Harry Potter's face.

"Oh that reminds me, I finished reading the first batch of books you lent me," Hermione said with her best innocent look. A couple of them had been hard books, too. She wondered how long it had taken him to finish reading them.

"Someday," said the Boy-Who-Lived, "when the distant descendants of Homo sapiens are looking back over the history of the galaxy and wondering how it all went so wrong, they will conclude that the original mistake was when someone taught Hermione Granger how to read."

"But you still lose," said Hermione. She held a hand to her chin and looked contemplative. "Now what exactly should you lose, I wonder?"

" What? "

"You lost the bet," Hermione explained, "so you have to pay a forfeit."

"I don't remember agreeing to this!"

"Really?" said Hermione Granger. She put a thoughtful look on her face. Then, as if the idea had only just then occurred to her, "We'll take a vote, then. Everyone in Ravenclaw who thinks Harry Potter has to pay up, raise your hand!"

" What? " shrieked Harry Potter again.

He spun around and saw that he was surrounded by a sea of raised hands.

And if Harry Potter had looked more carefully , he would have noticed that an awful lot of the onlookers seemed to be girls and that practically every female in the room had their hand raised.

"Stop!" wailed Harry Potter. "You don't know what she's going to ask! Don't you realize what she's doing? She's getting you to make an advance commitment now, and then the pressure of consistency will make you agree with whatever she says afterward!"
