Do longer prison sentences reduce crime?

It seems obvious that they should. Even if they don’t deter anyone, they at least keep criminals locked up where they can’t hurt law-abiding citizens. If, as the studies suggest, 1% of people commit 63% of the crime, locking up that 1% should dramatically decrease crime rates regardless of whether it scares anyone else. And blue state soft-on-crime policies have been followed by increasing theft and disorder.

On the other hand, people in the field keep saying there’s no relationship. For example, criminal justice nonprofit Vera Institute says that Research Shows That Long Prison Sentences Don’t Actually Improve Safety. And this seems to be a common position; William Chambliss, one of the nation’s top criminologists, said in 1999 that “virtually everyone who studies or works in the criminal justice system agrees that putting people in prison is costly and ineffective.”

This essay is an attempt to figure out what’s going on, who’s right, whether prison works, and whether other things work better/worse than prison.

Suppose something important will happen at a certain unknown point. As someone approaches that point, you might be tempted to warn that the thing will happen. If you’re being appropriately cautious, you’ll warn about it before it happens. Then your warning will be wrong. As things continue to progress, you may continue your warnings, and you’ll be wrong each time. Then people will laugh at you and dismiss your predictions, since you were always wrong before. Then the thing will happen and they’ll be unprepared.

Toy example: suppose you’re a doctor. Your patient wants to try a new experimental drug, 100 mg. You say “Don’t do it, we don’t know if it’s safe”. They do it anyway and it’s fine. You say “I guess 100 mg was safe, but don’t go above that.” They try 250 mg and it’s fine. You say “I guess 250 mg was safe, but don’t go above that.” They try 500 mg and it’s fine. You say “I guess 500 mg was safe, but don’t go above that.”

They say “Haha, as if I would listen to you! First you said it might not be safe at all, but you were wrong. Then you said it might not be safe at 250 mg, but you were wrong. Then you said it might not be safe at 500 mg, but you were wrong. At this point I know you’re a fraud! Stop lecturing me!” Then they try 1000 mg and they die.

The lesson is: “maybe this thing that will happen eventually will happen now” doesn’t count as a failed prediction.

I’ve noticed this in a few places recently.

Last month, I challenged 11,000 people to classify fifty pictures as either human art or AI-generated images.

I originally planned five human and five AI pictures in each of four styles: Renaissance, 19th Century, Abstract/Modern, and Digital, for a total of forty. After receiving many exceptionally good submissions from local AI artists, I fudged a little and made it fifty. The final set included paintings by Domenichino, Gauguin, Basquiat, and others, plus a host of digital artists and AI hobbyists.

One of these two pretty hillsides is by one of history’s greatest artists. The other is soulless AI slop. Can you tell which is which?

If you want to try the test yourself before seeing the answers, go here. The form doesn't grade you, so before you press "submit" you should check your answers against this key.

Last chance to take the test before seeing the results, which are:

In 1980, game theorist Robert Axelrod ran a famous Iterated Prisoner’s Dilemma Tournament.

He asked other game theorists to send in their best strategies in the form of “bots”, short pieces of code that took an opponent’s actions as input and returned one of the classic Prisoner’s Dilemma outputs of COOPERATE or DEFECT. For example, you might have a bot that COOPERATES a random 80% of the time, but DEFECTS against another bot that plays DEFECT more than 20% of the time, except on the last round, where it always DEFECTS, or if its opponent plays DEFECT in response to COOPERATE.

In the “tournament”, each bot “encountered” other bots at random for a hundred rounds of Prisoners’ Dilemma; after all the bots had finished their matches, the strategy with the highest total utility won.

To everyone’s surprise, the winner was a super-simple strategy called TIT-FOR-TAT:

The rise of Christianity is a great puzzle. In 40 AD, there were maybe a thousand Christians. Their Messiah had just been executed, and they were on the wrong side of an intercontinental empire that had crushed all previous foes. By 400, there were forty million, and they were set to dominate the next millennium of Western history.

Imagine taking a time machine to the year 2300 AD, and everyone is Scientologist. The United States is >99% Scientologist. So is Latin America and most of Europe. The Middle East follows some heretical pseudo-Scientology that thinks L Ron Hubbard was a great prophet, but maybe not the greatest prophet.

This can only begin to capture how surprised the early Imperial Romans would be to learn of the triumph of Christianity. At least Scientology has a lot of money and a cut-throat recruitment arm! At least they fight back when you persecute them! At least they seem to be in the game!

Polymarket (and prediction markets in general) had an amazing Election Night. They called states impressively early and accurately, kept the site stable through what must have been incredible strain, and have successfully gotten prediction markets in front of the world (including the Trump campaign). From here it’s a flywheel; victory building on victory. Enough people heard of them this election that they’ll never lack for customers. And maybe Trump’s CFTC will be kinder than Biden’s and relax some of the constraints they’re operating under. They’ve realized the long-time rationalist dream of a widely-used prediction market with high volume, deserve more praise than I can give them here, and I couldn’t be happier with their progress.

But I also think their Trump shares were mispriced by about ten cents, and that Trump’s victory in the election doesn’t do much to vindicate their numbers.

A red sun dawns over San Francisco. Juxtaposed against clouds and sea, it forms a patriotic tableau: blood red, deathly white, and the blue of the void. As its first rays touch the city, the frantic traffic slows to a crawl; even the birds cease to sing. It is Election Day in the United States.

Future generations will number American elections among history's greatest and most terrible spectacles. As we remember the Games in the Colosseum, or the bloody knives of Tenochtitlan, so they will remember us. That which other ages would relegate to a tasteful coronation or mercifully quick coup, we extend into an eighteen-month festival of madness.

Time to own the libs! ACX joins such based heterodox thinkers as Curtis Yarvin, Nick Fuentes, Richard Spencer, and David Duke in telling you what the woke Washington Post and failing LA Times don’t want you to know: Donald Trump is the wrong choice for US President.

If you’re in a swing state, we recommend you vote Harris; if a safe state, Harris or your third-party candidate of choice.

[EDIT/UPDATE: If you’re in a safe state and want to trade your protest vote with a swing state voter, or vice versa, go to https://www.swapyourvote.org/]

I mostly stand by the reasoning in my 2016 post, Slate Star Codex Endorses Clinton, Johnson, Or Stein. But you can read a better and more recent argument against Trump’s economic policy here, and against his foreign policy here. You can read an argument that Trump is a dangerous authoritarian here.

You can, but you won’t, because every American, most foreigners, and a substantial fraction of extra-solar aliens have already heard all of this a thousand times. I’m under no illusion of having anything new to say, or having much chance of changing minds. I write this out of a vague sense of deontological duty rather than a consequentialist hope that anything will happen.

And I’m writing the rest of this post because I feel bad posting a couple of paragraph endorsement and not following up. No guarantees this is useful to anybody.

Proposition 36 is a California ballot measure that increases mandatory sentences for certain drug and theft crimes. 

It’s also a referendum on over a decade of sentencing reform efforts stemming from California’s historical prison overcrowding crisis. Like many states, California passed increasingly tough sentencing laws through the 90s and early 2000s. This led to the state’s prisons operating massively over capacity: at its peak, a system built for 85,000 inhabitants housed 165,000. This was, among other things, a massive humanitarian crisis. The system was too overstretched to provide adequate healthcare to prisoners. Violence and suicide shot up.

 In 2011, the Supreme Court ruled that California prisons were so overcrowded that their conditions violated the 8th Amendment ban on cruel and unusual punishment. That year, the state assembly passed a package of reforms called "realignment," which shifted supervision of low-level offenders from the state to the counties. Then, in 2014, Californians voted for Proposition 47, which reduced some felony crimes to misdemeanors – theft of goods valued at under $950 and simple drug possession – and made people in prison for those crimes eligible for resentencing. Together, realignment and Prop 47 brought down California’s prison and jail population by 55,000. 

The campaign for Prop 36 is based on the premise that Prop 47 failed, leading to increased drug use and retail theft (but don’t trust me – it says so in the text of the measure). 36 would repeal some parts of 47, add some additional sentencing increases, and leave some elements in place (the LA Times has a good breakdown of the changes here).

It’s easy to round this off to a simple tradeoff: are we willing to put tens of thousands of people in jail if it would decrease the crime rate? But this would be the wrong way to think about the measure: there is no tradeoff. Prop 36 will certainly imprison many people, but it won’t help fight crime.
