Criminal Georg skews recidivism statistics

michaelkeenan:

Have you ever seen those concerning statistics about criminal recidivism? Like: 44% are re-arrested within a year, and 83% within nine years (source: this Department of Justice report).

I’d seen those statistics before, and been concerned. There’s a great case for shortening prison sentences for deterrence reasons, because likelihood of punishment is much more deterring than severity, but at least prison incapacitates criminals from plundering society while they’re imprisoned. Why hasten prison release if they’ll be back soon anyway? “Once a criminal, always a criminal?”, asks one headline about recidivism.

But today I learned that there’s a huge caveat to those statistics. The more often you go to prison, the more you’re counted in recidivism statistics.

Consider five people who go to prison. Four of them never commit another crime, but one of them was Criminal Georg, who is imprisoned ten times. Out of the fourteen prison sentences (ten for Georg, four for the others), nine of them are followed by recidivism (Georg’s first nine). The proportion of these people who are serial criminals is 20%, but the recidivism rate is 64%.

When considering people rather than prison releases, the recidivism rate is lower than I thought.

Pet peeve: when public codebases for machine learning research projects do “the main.py thing”

That is: they come bundled with a single CLI script, usually called “main.py,” which is capable of calling several entirely different code paths.

Training, evaluation, prediction, one or more “experiments” from the paper, each stage of training if there’s more than one, and anything else the authors did – it’s all “main.py” with different arguments.

This is bad for a lot of reasons, including:

1. It takes the arguments of several conceptually distinct functions, and smooshes them all into one argument namespace.
   
   This often requires renaming or overloading them to avoid collisions. An argument called, say, “eval_steps” might do different things when it’s controlling evaluation-during-training vs. when it’s controlling evaluation on its own, or it might just control one of those but not the other.
   
   This problem could be trivially solved by using multiple CLI scripts.
2. In practice, “main.py"s are rarely just simple wrappers that select a function and pass CLI arguments to it. They usually contain business logic, like calling functions with hardcoded but non-default arguments, or using the script arguments to make branching if/else decisions about function arguments.
   
   Everything can now comes in two flavors, the "CLI flavor” and the “library flavor.” There’s no way to intuitively assign meaning to these distinctions, because there’s no intuitive reason for them to exist at all. When reading/using the code, you feel like you’re watching two sets of intentions argue with each other, both warning you not to trust the other one.

I don’t see any upsides of this approach?

I imagine it’s just a thing people started doing, and then everyone noticed everyone else was doing it, and researchers tend to be risk-averse about everything that’s not related to the meat of their research, so why rock the boat…

(If you’ve done this, don’t feel bad, I’m not annoyed at you. Just at the pattern.)

(… at least it’s not the even worse pattern where there are multiple scripts, but they only run benchmarks or other narrow tasks, and the ability to train/eval/predict generally is technically there but locked behind each script’s tangle of business logic. The name “run_squad.py” still haunts me)

Maria

Five minutes to midnight.

The apartment is not particularly lighted, but that’s fine, because Maria is an aspiring cosmologist. The apartment has a view of the neon-lit River Tam and the skyscrapers of Columbia, and those are almost as interesting as the view outside, where the night is darker and there are no skyscrapers. Best of all, there is a voluminous curtain, between the view and the streetlights, dividing the room into a living and a sleeping area.

Maria fidgets with the cordless light she always carries with her, seeking her preferred position. The cord is mostly for controlling her messy short hair, but it’s good to have it in addition to her preferred hairnet, because the light curls messily in her fist.

It’s a few minutes until midnight, and Maria is exhausted, but she still isn’t sleeping, and she’s reached for the toy car again. She doesn’t know what it is, but she knows that she likes it. She pauses a moment, to observe the toy car. It doesn’t look quite right – the wheels are wrong, and there is an odd-looking bump on its top half. Whatever this thing is, Maria finds herself wondering why it doesn’t have any wheels at all – and why Maria would want one, even if there were no apparent reason, and why no one told her that she would want them.

She says to herself, this moment, in silent reflection, that this is not a problem. This is not an imagined need. This is not an imagined desire. This is a real, personal part of her, and she will work with it, and it will go away.

Just as she knew, she says to herself, just as the toy car knew, this moment she says to herself, “I like my car, but I like my doll more.”

The corded light is not her most treasured possession, but Maria still presses it to her face. She says to herself, just as the toy car knew, that this is a cause, not just an effect.

The room is silent. Then, from the corner of her eye: a flicker of movement, not even a shadow. Maria turns, and there is Hank, sitting on the edge of the bed, looking up at her with a light, hopeful smile.

And she knows, she knows, that this is a problem, and she does not have to think about it any more.

She sits down on the bed, and gets on all fours. It is the most ridiculous thing, she thinks, sitting down on the bare, metal bed. She has on a pair of pajama pants, and a T-shirt, and a pair of cargo shorts. She looks ridiculous. But she has on this, now, so she will take it. And she will make the most of it.

She pulls the toy car out of the pocket of her shirt, and it makes a garbled noise, as if it has no battery. The battery is now fixed in her pocket, and she knows, she knows, that she is about to do something incredibly stupid.

She steps forward, and the toy car makes a garbled noise again, but this time it is a laugh. She smiles, a rueful, mischievous smile, and steps forward, and the car makes a second garbled noise, and she freezes.

There is a voice, barely above a whisper in the silent apartment, and it is saying two things. One was “hello,” and the other was “would you like some help?”

Maria turns around, and there is a woman, tall and skinny, with short brown hair. She has a bandanna around her face and a bandaged hand. The woman is female, Maria realizes.

“Hello,” says the woman, in a voice that is halfway between a whisper and a shout.

Maria nods.

“Are you Maria?” the woman asks.

“Yes,” Maria says.

“Do you know who I am?”

“No.”

“Well, then. You’re me. I’m Lacroix. Do you know me?”

“No,” says Maria. “Where are you from?”

“I’m not from anywhere. I’m an inter-universal phenomenon.”

“What are you?”

“An effect. I’m a phenomenon. I’m a person made of action and consequence.”

“I’m not from anywhere, either,” says Maria.

“Then you’re not from anywhere. You’re a person made out of action and consequence. A person made out of atoms and space. I’m a person made out of action and consequence, and I’m going to help you make a person, too.”

“Wait, wait, wait,” says Maria.

“What?”

“Do you mean I’m going to make a person out of you, too?”

“No. That’s not what I meant.”

“But it’s what I meant.”

“What?”

“I mean – I don’t know how to explain this, but you’re a phenomenon and I’m a person made out of action and consequence.”

“I’m not from anywhere, either,” says Maria. “I’m not from anything. I’m not from your universe, I’m from another universe entirely. Your universe, and mine, are both made of action and consequence, and we’re both connected by an action and a consequence.”

“That’s not what you meant.”

“No, it’s not. Are you from anywhere? Because if so, then if so, then you’re not from anywhere. You’re a person made out of action and consequence, and I’m a phenomenon, and we’re connected by an action and a consequence. That’s how things are, because actions and consequences are made out of atoms and space, and there’s nothing else there, except action and consequence, so if you’re not from anywhere, then you’re not from anywhere. But if you’re not from anywhere, then I’m not from anywhere, and we’re connected by an action and a consequence.”

“I don’t – I don’t understand,” says Maria.

“Then don’t.”

“I’m not from anywhere,” says Maria.

“That’s the beginning and the end of how I understand you,” says the woman.

“I’m not from anywhere,” says Maria.

“You say you’re not from anywhere, but that you’re not from anywhere. I’m not from anywhere, either, but I say I’m not from anywhere. You say you’re a person made out of action and consequence. I say I’m a person made out of action and consequence. I say I’m a thing made out of action and consequence. I’m a thing made out of action and consequence. I’m a thing made out of atoms and space. We’re made out of atoms and space, and we’re connected by action and consequence. We’re connected by action and consequence, and we’re connected by an action and a consequence. Are you a person made of action and consequence?”

“No, I’m not,” says Maria.

“Then I’m not a person made out of action and consequence,” says Maria.

“Then I’m a person made out of action and consequence, and I’m connected to you by an action and a consequence, and I’m connected to you by an action and a consequence, and we’re connected by action and consequence, and we’re connected by an action and a consequence, and we’re connected by an action and a consequence, and we’re connected by an action and a consequence, and I’m not a person made out of action and consequence,” says Maria.

“That’s more like it,” says the woman.

“I’m sorry,” says Maria, “but that’s the definition of a person, and there

Chapter 11

The ground shakes. Calvus stumbles. He cannot see.

There is a door, just barely visible in the shifting cloud-shapes that are the only things in this cavern other than Calvus himself and the terminal. It leads into some sort of control room. Calvus knows nothing about this room’s purpose, or its state of affairs. He staggers, falls, then gets to his feet, half-crouches, looks around. No one is around to see him.

The ground shakes again. Calvus’s head spins, and he thinks he sees something glowing on the other side of the door. But it is not a light – it was not even bright red.

It was something that flashed, a brief paleness, and then filled his field of view. It was a face. A very young face, with a hint of youthful energy. It was smiling. And something else, a fourth thing, flashed into his field of vision, too. It was a badge.

The young man, or boy, strides forward, a happy sort of gait, and he passes the badge to Calvus. It is a badge for checking your pulse. And it says CALVUS HAS BEEN PASSED OVER BY GOD.

“Hello, Calvus,” says the young man. “My name is Jesus.”

“Hello, Jesus,” says Calvus.

“I met you in a vision,” says Jesus. “You were lost in thought. I wanted to help you.”

“You can do that?” says Calvus.

Jesus looks at him, a smirk playing at the corner of his mouth. “I’ve been trying to find a way to do that for a long time. I started this place, so that I could do things like this.”

“And I was hoping to do something like this,” says Calvus, “and help others in my way.”

“You seem like you could help people,” says Jesus. “Maybe in a small way. You seem kind.”

“I could help people in a small way,” says Calvus.

“You’re an imposter,” says Jesus.

“An imposter?” says Calvus.

“You’re not who you say you are,” says Jesus. “Even the things you’ve done, they’ve looked like someone else. But I know your kind. You’re like me. Can’t be proven, but everyone believes.”

Jesus looks around – there are many others, standing, smiling, and the glow has begun to dim.

Calvus looks around, too. He sees Mary, and Joseph, and Catherine.

“I’m Jesus,” he says.

“We’re here, at the End of the World,” says Jesus. “It’s always been like this. There’s something very important in every world, at every age. And you’re all going to die. And there’s nothing you can do about it. But there’s something that’s important in all of us that no one’s realized yet. We’ve all been pretending that there isn’t something very important in us. But you all know. You’re all so young. And this is your destiny. I can’t do anything for you, because I don’t have anything in me. But there’s something inside of all of us. You see it. We’re all looking for it. And you’re all looking for it together.”

“I can help you,” says Calvus.

“We have so much to give each other,” says Jesus. “We have so much that is our own. There’s nothing on earth like the love we’re feeling. We’re all going to understand each other better. There’s a lot of things we can give each other.”

“I can learn everything you can,” says Calvus.

“Everyone can learn everything they can,” says Jesus. “We’re all looking for your true nature, your true nature, that shines through you all. You all have it within you.”

“I’m not like any of you,” says Calvus.

“No one is like any other,” says Jesus. “You’re all like Jesus. You’re all one. You see all the others. You’re all looking for what’s important in each other. You don’t need to argue with each other. We can just be friends.”

Mary and Catherine smile and kiss Jesus. The other children look at them. The children in the tiled room smile and kiss Jesus.

At last the bright glow fades.

But the child in Calvus’s arms, his shadow, is not dead.

When the blinding light returns, there are children everywhere, and people and giants, and they shout and curse each other, and the blond child is crying, but he does not let go of his Calvus.

One by one, the children turn away from Calvus and walk away from him, away from the light, toward the wall opposite the tall, manacled figure, who is now speaking in a dead, fixed voice.

The children all pass him, as if turned away from something they had looked to see.

The blond child passes him. Then the child in the tiled room. Then the child with the gun, who passed Calvus after he had killed the people.

The boy with the scarf, who passed Calvus on the stairs. The boy with a noose around his neck. The boy with his hands behind his head, but the child is no longer pressing his hands behind his head.

And then Calvus is alone.

He looks at the child in his arms. The child is so small, and so strange. There is something red on his cheek, and a mouth, and eyes, and a face, something like a man’s, but distorted. He feels no hatred, but some part of him feels drawn to him. To protect him.

There is a knock on the door.

“Come in,” says Jesus.

There is a knock on the door.

“Come in,” says Jesus.

There is a knock on the door.

“Come in,” says Jesus.

It is Mary. She has come with Catherine. The others have not come back. She stands at the threshold, looking down at him. “We missed you,” she says.

“I can’t see,” says Calvus.

“It’s okay,” she says. “We’re here.”

There is a knock on the door. “Come in,” says Jesus.

There is a knock on the door.

“Come in,” says Jesus.

There is a knock on the door.
