Harry Potter and the Methods of Rationality (10 page)

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 -”

Draco groaned. “Are we
really
going to do this?”

“You don’t have to drink it but I
have
to investigate.
Have
to. How much?”

“Five Knuts the can,” the stallholder said.

“
Five Knuts?
You can sell reality-manipulating fizzy drinks for
five Knuts the can?”
Harry reached into his pouch, said “four Sickles, four Knuts”, and slapped them down on the counter. “Two dozen cans please.”

“I’ll also take one,” Draco sighed, and started to reach for his pockets.

Harry shook his head rapidly. “No, I’ve got this, doesn’t count as a favor either, I want to see if it works for you too.” He took a can from the stack now placed on the counter and tossed it to Draco, then started feeding his pouch. The pouch’s Widening Lip ate the cans accompanied by small burping noises, which wasn’t exactly helping to restore Harry’s faith that he would someday discover a reasonable explanation for all this.

Twenty-two burps later, Harry had the last purchased can in his hand, Draco was looking at him expectantly, and the two of them pulled the ring at the same time.

Harry rolled up his scarf to expose his mouth, and they tilted their heads back and drank the Comed-Tea.

It somehow
tasted
bright green - extra-fizzy and limer than lime.

Aside from that, nothing else happened.

Harry looked at the stallholder, who was watching them benevolently.

All right, if this guy just took advantage of a natural accident to sell me twenty-four cans of nothing
, I’m going to applaud his creative entrepreneurial spirit and then kill him.

“It doesn’t always happen immediately,” the stallholder said. “But it’s guaranteed to happen once per can, or your money back.”

Harry took another long drink.

Once again, nothing happened.

Maybe I should just chug the whole thing as fast as possible… and hope my stomach doesn’t explode from all the carbon dioxide, or that I don’t burp while drinking it…

No, he could afford to be a
little
patient. But honestly, Harry didn’t see how this was going to work. You couldn’t go up to someone and say “Now I’m going to surprise you” or “And now I’m going to tell you the punchline of the joke, and it’ll be really funny.” It ruined the shock value. In Harry’s state of mental preparedness, Lucius Malfoy could have walked past in a ballerina outfit and it wouldn’t have made him do a proper spit-take. Just what sort of wacky shenanigan was the universe supposed to cough up
now?

“Anyway, let’s sit down,” Harry said. He prepared to swig another drink and started towards the distant seating area, which put him at the right angle to glance back and see the portion of the stall’s newspaper stand that was devoted to a newspaper called
The Quibbler
, which was showing the following headline:

BOY-WHO-LIVED GETS
DRACO MALFOY PREGNANT

“
Gah!
” screamed Draco as bright green liquid sprayed all over him from Harry’s direction. Draco turned to Harry with fire in his eyes and grabbed his own can. “You son of a mudblood! Let’s see how
you
like being spat upon!” Draco took a deliberate swig from the can just as his own eyes caught sight of the headline.

In sheer reflex action, Harry tried to block his face as the spray of liquid flew in his direction. Unfortunately he blocked using the hand containing the Comed-Tea, sending the rest of the green liquid to splash out over his shoulder.

Harry stared at the can in his hand even as he went on choking and spluttering and the green colour started to vanish from Draco’s robes.

Then he looked up and stared at the newspaper headline.

BOY-WHO-LIVED GETS
DRACO MALFOY PREGNANT

Harry’s lips opened and said, “buh-bluh-buh-buh…”

Too many competing objections, that was the problem. Every time Harry tried to say “But we’re only eleven!” the objection “But men can’t get pregnant!” demanded first priority and was then run over by “But there’s nothing between us, really!”

Then Harry looked down at the can in his hand again.

He was feeling a deep-seated desire to run away screaming at the top of his lungs until he dropped from lack of oxygen, and the only thing stopping him was that he had once read that outright panic was the sign of a
truly
important scientific problem.

Harry snarled, threw the can violently into a nearby rubbish bin, and stalked back over to the stall. “One copy of
The Quibbler,
please.” Harry paid over four more Knuts, retrieved another can of Comed-Tea from his pouch, and then stalked over to the picnic area with the blond-haired boy, who was staring at his own can with an expression of frank admiration.

“I take it back,” Draco said, “that was pretty good.”

“Hey, Draco, you know what I bet is even better for becoming friends than exchanging secrets? Committing murder.”

“I have a tutor who says that,” Draco allowed. He reached inside his robes and scratched himself with an easy, natural motion. “Who’ve you got in mind?”

Harry slammed
The Quibbler
down hard on the picnic table. “The guy who came up with this headline.”

Draco groaned. “Not a guy. A girl. A
ten-year-old
girl, can you believe it? She went nuts after her mother died and her father, who owns this newspaper, is
convinced
that she’s a seer, so when he doesn’t know he asks Luna Lovegood and believes
anything
she says.”

Not really thinking about it, Harry pulled the ring on his next can of Comed-Tea and prepared to drink. “Are you kidding me? That’s even worse than Muggle journalism, which I would have thought was physically impossible.”

Draco snarled. “She has some sort of perverse obsession about the Malfoys, too, and her father is politically opposed to us so he prints every word. As soon as I’m old enough I’m going to rape her.”

Green liquid spurted out of Harry’s nostrils, soaking into the scarf still covering that area. Comed-Tea and lungs did not mix, and Harry spent the next few seconds frantically coughing.

Draco looked at him sharply. “Something wrong?”

It was at this point that Harry came to the sudden realisation that (a) the sounds coming from the rest of the train platform had turned into more of a blurred white noise at around the same time Draco had reached inside his robes, and (b) when he had discussed committing murder as a bonding method, there had been exactly one person in the conversation who’d thought they were joking.

Right. Because he
seemed
like such a normal kid. And he
is
a normal kid, he is just what you’d
expect
a baseline male child to be like if Darth Vader were his doting father.

“Yes, well,” Harry coughed, oh god how was he going to get out of this conversational wedge, “I was just surprised at how you were willing to discuss it so openly, you didn’t seem worried about getting caught or anything.”

Draco snorted. “Are you joking?
Luna Lovegood’s
word against mine?”

Holy crap on a holy stick. “There’s no such thing as magical truth detection, I take it?”
Or DNA testing… yet.

Draco looked around. His eyes narrowed. “That’s right, you don’t know anything. Look, I’ll explain things to you, I mean the way it really works, just like you were already in Slytherin and asked me the same question. But you’ve got to swear not to say anything about it.”

“I swear,” Harry said.

“The courts use Veritaserum, but it’s a joke really, you just get yourself Obliviated before you testify and then claim the other person was Memory-Charmed with a fake memory. Of course if you’re just some normal person, the courts presume in favor of Obliviation, not False Memory Charms. But the court has discretion, and if
I’m
involved then it impinges on the honor of a Noble House, so it goes to the Wizengamot, where Father has the votes. After I’m found not guilty the Lovegood family has to pay reparations for tarnishing my honor. And they know from the start that’s how it’ll go, so they’ll just keep their mouths shut.”
