Harry Potter and the Methods of Rationality

After she'd decided to be a hero, Hermione had done the obvious thing, and gone to the Hogwarts library and taken out books on how to be a hero. Then she'd returned those books back to their shelves, because it'd been patently obvious that none of the authors had been actual heroes themselves. Instead she'd just read five times over, until she'd memorized every word, the thirty inches by Godric Gryffindor that was all his autobiography and his life's advice. (Or the English translation, anyway; she couldn't read Latin yet.) Godric Gryffindor's autobiography had been a lot more compressed than the books Hermione was used to reading, he used one sentence to say things that should've taken thirty inches just by themselves, and then there was another sentence after that...

But it was clear from what she'd read that, while Defying Authority wasn't the point of being a hero, you couldn't be a hero if you were too scared to do it. And Hermione Granger knew by now how others saw her, and she knew what other people thought she couldn't do.

Hermione hefted her picket sign a little higher and concentrated on breathing slowly and rhythmically instead of hyperventilating until she fell over.

"Really?" said Miss Preece in a tone of undisguised fascination. "They couldn't vote?"

"Indeed," said Professor Sinistra. (The Astronomy Professor's hair was still dark, and her dark face only slightly lined; Hermione would have guessed her age at around seventy, except -) "I quite remember my mother's rejoicing when they announced the Qualification of Women Act, although she did not actually qualify." (Which meant that Professor Sinistra had been around her Muggle family in 1918.) "And that wasn't the worst of it. Why, just a few centuries earlier -"

Thirty seconds later all the non-Muggleborns, male and female both, were staring at Professor Sinistra with utterly shocked expressions. Hannah had dropped her sign.

"And that wasn't the worst of it either, not by half," finished Professor Sinistra. "But you see where this sort of thing could potentially lead."

"Merlin preserve us," said Penelope Clearwater in a strangled voice. "You mean that's how men would treat us if we didn't have wands to defend ourselves?"

"Hey!" said one of the boy prefects. "That's not -"

There was a short, sardonic laugh from the direction of Professor Quirrell. When Hermione turned her head to look she saw that the Defense Professor was still idly toying with the button, not bothering to glance up at the rest of them, as he said, "Such is human nature, Miss Clearwater. Rest assured that you would be no kinder, if witches had wands and men lacked them."

"I hardly think so!" snapped Professor Sinistra.

A cold chuckle. "I suspect it happens more often than any dare suggest, in the proudest pureblood families. Some lonely witch spies a handsome Muggle; and thinks how very easy it would be, to slip the man a love potion, and by him be adored alone and utterly. And since she knows he can offer her no resistance, why, it is only natural for her to take from him whatever she pleases -"

"Professor Quirrell!" said Professor McGonagall sharply.

"I'm sorry," Professor Quirrell said mildly, his eyes still looking down on the button in his hand, "are we all still pretending it doesn't happen? My apologies, then."

Professor Sinistra snapped, "And I suppose that wizards don't -"

"There are children present, Professors!" Again Professor McGonagall.

"Some do," Professor Quirrell said equably, as though discussing the weather. "Although personally, I don't."

There was a bit of silence, for a time. Hermione put up her sign again - it had slipped down to her shoulder while she was listening. She'd never thought of that, not even a little, and now she was trying not to think of it, and her stomach was feeling a bit queasy. She looked in Harry Potter's direction, not quite knowing why she did; and she saw that Harry's face was perfectly still. A chill ran down her spine before she looked away, not quite fast enough to miss the small nod that Harry gave her, as though they were agreeing on something.

"To be fair," Professor Sinistra said after a while, "since I received my Hogwarts letter I can't recall encountering any prejudice on account of being a woman, or colored. No, now it is all for being a Muggleborn. I believe Miss Granger said that it was just with heroes that she found a problem, so far?"

It took Hermione a moment to recognize that she'd been asked the question, and then she said "Yes," in a tone that squeaked a little. This whole thing had blown up a bit larger than she'd imagined when she'd started it.

"What exactly did you check, Miss Granger?" said Professor Vector. She looked older than Professor Sinistra, her hair starting to gray a little; Hermione hadn't ever come close to Professor Vector in person until the Arithmancy Professor had asked her for a button.
