Harry Potter and the Methods of Rationality

the experimenter would instruct the subjects to treat non-answers as wrong answers and continue.

At the 315-volt level the pounding on the wall would be repeated.

After that nothing would be heard.

If the subject objected or refused to press a switch, the experimenter, maintaining an impassive demeanor and dressed in a gray lab coat, would say 'Please continue', then 'The experiment requires that you continue', then 'It is absolutely essential that you continue', then 'You have no other choice, you must go on'. If the fourth prod still didn't work, the experiment halted there.

Before running the experiment, Milgram had described the experimental setup, and then asked fourteen psychology seniors what percentage of subjects they thought would go all the way up to the 450-volt level, what percentage of subjects would press the last of the two switches marked XXX, after the victim had stopped responding.

The most pessimistic answer had been 3%.

The actual number had been 26 out of 40.

The subjects had sweated, groaned, stuttered, laughed nervously, bitten their lips, dug their fingernails into their flesh. But at the experimenter's prompting, they had, most of them, gone on administering what they believed to be painful, dangerous, possibly lethal electrical shocks. All the way to the end.

Harry could hear Professor Quirrell laughing, in his mind; the Defense Professor's voice saying something along the lines of: Why, Mr. Potter, even I had not been so cynical; I knew men would betray their most cherished principles for money and power, but I did not realize that a stern look also sufficed.

It was dangerous, to try and guess at evolutionary psychology if you weren't a professional evolutionary psychologist; but when Harry had read about the Milgram experiment, the thought had occurred to him that situations like this had probably arisen many times in the ancestral environment, and that most potential ancestors who'd tried to disobey Authority were dead. Or that they had, at least, done less well for themselves than the obedient. People thought themselves good and moral, but when push came to shove, some switch flipped in their brain, and it was suddenly a lot harder to heroically defy Authority than they thought. Even if you could do it, it wouldn't be easy, it wouldn't be some effortless display of heroism. You would tremble, your voice would break, you would be afraid; would you be able to defy Authority even then?

Harry blinked, then; because his brain had just made the connection between Milgram's experiment and what Hermione had done on her first day of Defense class, she'd refused to shoot a fellow student, even when Authority had told her that she must, she had trembled and been afraid but she had still refused. Harry had seen that happen right in front of his own eyes and he still hadn't made the connection until now...

Harry stared down at the reddening horizon, the Sun was sinking lower, the sky fading, darkening, even if most of it was still blue, soon it would turn to night. The gold and red colors of Sun and sunset reminded him of Fawkes; and Harry wondered, for a moment, if it must be a sad thing to be a phoenix, and call and cry and scream without being heeded.

But Fawkes would never give up, as many times as he died he would always be reborn, for Fawkes was a being of light and fire, and despairing over Azkaban belonged to the darkness just as much as did Azkaban itself.

If you were given a glass half-empty and half-full, then that was the way reality was, that was the truth and it was so; but you still had a choice of how to feel about it, whether you would despair over the empty half or rejoice in the water that was there.

Milgram had tried certain other variations on his test.

In the eighteenth experiment, the experimental subject had only needed to call out the test words to the victim strapped into the chair, and record the answers, while someone else pressed the switches. It was the same apparent suffering, the same frantic pounding followed by silence; but it wasn't you pressing the switch. You just watched it happen, and read the questions to the person being tortured.

37 of 40 subjects had continued their participation in that experiment to the end, the 450-volt end marked 'XXX'.

And if you were Professor Quirrell, you might have decided to feel cynical about that.

But 3 out of 40 subjects had refused to participate all the way to the end.

The Hermiones.

They did exist, in the world, the people who wouldn't fire a Simple Strike Hex at a fellow student even if the Defense Professor ordered them to do it. The ones who had sheltered Gypsies and Jews and homosexuals in their attics during the Holocaust, and sometimes lost their lives for it.

And were those people from some other species than humanity? Did they have some extra gear in their heads, some additional chunk of neural circuitry, which lesser mortals did not possess? But that was not likely, given the logic of sexual reproduction which said that the genes for complex machinery would be scrambled beyond repair, if they were not universal.

Whatever parts Hermione was made from, everyone had those same parts inside them somewhere...

...well, that was a nice thought but it wasn't strictly true, there was such a thing as literal brain damage, people could lose genes and the complex machine could stop working, there were sociopaths and psychopaths, people who lacked the gear to care. Maybe Lord Voldemort had been born like that, or maybe he had known good and yet still chosen evil; at this point it didn't matter in the slightest. But a supermajority of the population ought to be capable of learning to do what Hermione and Holocaust resisters did.

The people who had been run through the Milgram experiment, who had trembled and sweated and nervously laughed as they went all the way to pressing the switches marked 'XXX', many of them had written to thank Milgram, afterward, for what they had learned about themselves. That, too, was part of the story, the legend of that legendary experiment.

The Sun had almost sunk below the horizon now, a last golden tip peeking above the faraway tops of trees.

Harry looked at it, that tip of Sun, his glasses were supposed to be proof against UV so he ought to be able to look directly at it without damaging his eyes.
