Eliezer Yudkowsky - Harry Potter and the Methods of Rationality

Draco shot Harry another odd look. "Just what do you know about Father?"

"Um... seat on the Wizengamot, seat on Hogwarts' Board of Governors, incredibly wealthy, has the ear of Minister Fudge, has the confidence of Minister Fudge, probably has some highly embarrassing photos of Minister Fudge, most prominent blood purist now that the Dark Lord's gone, former Death Eater who was found to have the Dark Mark but got off by claiming to be under the Imperius Curse, which was ridiculously implausible and pretty much everyone knew it... evil with a capital 'E' and a born killer... I think that's it."

Draco's eyes had narrowed to slits. "McGonagall told you that, did she."

"No, she wouldn't say anything to me about Lucius afterwards, except to stay away from him. So during the Incident at the Potions Shop, while Professor McGonagall was busy yelling at the shopkeeper and trying to get everything under control, I grabbed one of the customers and asked them about Lucius."

Draco's eyes were wide again. "Did you really? "

Harry gave Draco a puzzled look. "If I lied the first time, I'm not going to tell you the truth just because you ask twice."

There was a certain pause as Draco absorbed this.

"You're so completely going to be in Slytherin."

"I'm so completely going to be in Ravenclaw, thank you very much. I only want power so I can get books."

Draco giggled. "Yeah, right. Anyway... to answer what you asked..." Draco took a deep breath, and his face turned serious. "Father once missed a Wizengamot vote for me. I was on a broom and I fell off and broke a lot of ribs. It really hurt. I'd never hurt that much before and I thought I was going to die. So Father missed this really important vote, because he was there by my bed at St. Mungo's, holding my hands and promising me that I was going to be okay."

Harry glanced away uncomfortably, then, with an effort, forced himself to look back at Draco. "Why are you telling me that? It seems sort of... private..."

Draco gave Harry a serious look. "One of my tutors once said that people form close friendships by knowing private things about each other, and the reason most people don't make close friends is because they're too embarrassed to share anything really important about themselves." Draco turned his palms out invitingly. "Your turn?"

Knowing that Draco's hopeful face had probably been drilled into him by months of practice did not make it any less effective, Harry observed. Actually it did make it less effective, but unfortunately not ineffective. The same could be said of Draco's clever use of reciprocation pressure for an unsolicited gift, a technique which Harry had read about in his social psychology books (one experiment had shown that an unconditional gift of $5 was twice as effective as a conditional offer of $50 in getting people to fill out surveys). Draco had made an unsolicited gift of a confidence, and now invited Harry to offer a confidence in return... and the thing was, Harry did feel pressured. Refusal, Harry was certain, would be met with a look of sad disappointment, and maybe a small amount of contempt indicating that Harry had lost points.

"Draco," Harry said, "just so you know, I recognise exactly what you're doing right now. My own books called it reciprocation and they talk about how giving someone a straight gift of two Sickles was found to be twice as effective as offering them twenty Sickles in getting them to do what you want..." Harry trailed off.

Draco was looking sad and disappointed. "It's not meant as a trick, Harry. It's a real way of becoming friends."

Harry held up a hand. "I didn't say I wasn't going to respond. I just need time to pick something that's private but just as non-damaging. Let's say... I wanted you to know that I can't be rushed into things." A pause to reflect could go a long way in defusing the power of a lot of compliance techniques, once you learned to recognise them for what they were.

"All right," Draco said. "I'll wait while you come up with something. Oh, and please take off the scarf while you say it."

Simple but effective.

And Harry couldn't help but notice how clumsy, awkward, graceless his attempt at resisting manipulation / saving face / showing off had appeared compared to Draco. I need those tutors.

"All right," Harry said after a time. "Here's mine." He glanced around and then rolled the scarf back up over his face, exposing everything but the scar. "Um... it sounds like you can really rely on your father. I mean... if you talk to him seriously, he'll always listen to you and take you seriously."

Draco nodded.

"Sometimes," Harry said, and swallowed. This was surprisingly hard, but then it was meant to be. "Sometimes I wish my own Dad was like yours." Harry's eyes flinched away from Draco's face, more or less automatically, and then Harry forced himself to look back at Draco.

Then it hit Harry what on Earth he'd just said , and Harry hastily added, "Not that I wish my Dad was a flawless instrument of death like Lucius, I only mean taking me seriously -"

"I understand," Draco said with a smile. "There... now doesn't it feel like we're a little closer to being friends?"

Harry nodded. "Yeah. It does, actually. Um... no offence, but I'm going to put on my disguise again, I really don't want to deal with -"

"I understand."

Harry rolled the scarf back down over his face.

"My father takes all his friends seriously," Draco said. "That's why he has lots of friends. You should meet him."

"I'll think about it," Harry said in a neutral voice. He shook his head in wonder. "So you really are his one weak point. Huh."

Now Draco was giving Harry a really odd look. "You want to go get something to drink and find somewhere to sit down?"

Harry realised he had been standing in one place for too long, and stretched himself, trying to crick his back. "Sure."

The platform was starting to fill up now, but there was still a quieter area on the far side away from the red steam engine. Along the way they passed a stall containing a bald, bearded man offering newspapers and comic books and stacked neon-green cans.

The stallholder was, in fact, leaning back and drinking out of one of the neon-green cans at the exact point when he spotted the refined and elegant Draco Malfoy approaching along with a mysterious boy looking incredibly stupid with a scarf tied over his face, causing the stallholder to experience a sudden coughing fit in mid-drink and dribble a large amount of neon-green liquid onto his beard.

"'Scuse me," Harry said, "but what is that stuff, exactly?"

"Comed-Tea," said the stallholder. "If you drink it, something surprising is bound to happen which makes you spill it on yourself or someone else. But it's charmed to vanish just a few seconds later -" Indeed the stain on his beard was already disappearing.

"How droll," said Draco. "How very, very droll. Come, Mr. Bronze, let's go find another -"

"Hold on," Harry said.

" Oh come on! That's just, just juvenile! "

"No, I'm sorry Draco, I have to investigate this. What happens if I drink Comed-Tea while doing my best to keep the conversation completely serious?"

The stallholder smiled mysteriously. "Who knows? A friend walks by in a frog costume? Something unexpected is bound to happen -"

"No. I'm sorry. I just don't believe it. That violates my much-abused suspension of disbelief on so many levels I don't even have the language to describe it. There is, there is just no way a bloody drink can manipulate reality to produce comedy setups , or I'm going to give up and retire to the Bahamas -"
