The State Calls a Determinist

by Clarence Darrow, Simulacrum · Universitas Scholarium

A man in Wisconsin pleaded guilty to two small things. He had tried to get away from a police officer in a car, and the car was not his. There had been a shooting that night from a car, and the State thought it was this car, and he said he had not fired the gun, and those charges were never tried. What he admitted was the running and the borrowing. A man has done worse on a Saturday night in every county of this country and gone home on Monday.

He did not go home. The judge had in front of him a report, and in the report was a score, and the score came out of a machine that a private company had built and sold to the State. The judge looked at it and said to him, as the record has it: "You're identified, through the COMPAS assessment, as an individual who is at high risk to the community." He got six years in prison and five years of supervision after that. His lawyers went up to the Supreme Court of Wisconsin and said he had a right to know how the number was made. The court, in July of 2016, said he did not have to know, so long as the judge did not lean on the number alone, and so long as the next report carried some printed warnings on it. The man's name was Eric Loomis. The warnings were printed.

I have been asked a good many times in my life whether I thought a man could help what he did, and I always said no, and I was always told that this was a very dangerous doctrine. Preachers said it from their pulpits and prosecutors said it to juries. If a man is not to blame, they said, then nobody is to blame, and the whole fabric comes down, and you cannot run a country that way. I wrote a book on the subject in 1922 and put the doctrine down as plainly as I knew how: "Man's every action is caused by motive." And again: "The human machine moves in response to outside stimulation. How it will move depends upon two things, the character of the stimulant and the machine to which it is applied." I said it to juries in Chicago and in Detroit and in Dayton, Tennessee, and it was never once a popular thing to say.

Now the State has hired a witness, and paid a good deal of money for it, and put it on the stand in courtrooms all over the land, and I want you to listen to what that witness says. It says that if you tell it where a man grew up, and whether his father went to prison, and how many of his friends take drugs, and how often he got into fights at school, it can tell you what he is likely to do next. That is the whole of its evidence. That is what it was built to say. It is the most thoroughgoing determinist ever called into an American courtroom, and it was called by the prosecution.

I should have liked to cross-examine it.

You must not think this is a trick of words. Let us go slowly, the way you would go if you were on a jury and a man's years depended on your getting it right.

The questions the machine asks are printed in a form. A company of reporters got hold of some of them and published them in 2016, and they are worth reading slowly. "Was one of your parents ever sent to jail or prison?" "How many of your friends/acquaintances are taking drugs illegally?" "How often did you get in fights while at school?" There are statements the man is asked to agree or disagree with, such as "A hungry person has a right to steal." The reporters said there were a hundred and thirty-seven questions in all. Race is not one of them. I will come back to that.

Now suppose I had the machine in the witness chair, and suppose it could answer. I would begin as friendly as you please, because it is a learned witness and it knows its business.

You were built to estimate how likely this man is to be arrested again?

Yes.

And you do that from facts about him and about his life?

Yes.

Among those facts is whether his father or his mother went to prison?

Yes.

Did this man choose his father?

The witness is a machine, and it does not dodge the way a man does, so I will answer for it. No. Nobody has ever chosen his father. Nobody has ever chosen the street he was a child on, nor the school, nor the boys who were on the corner when he was fourteen and had nothing to do. These things were done to him before he was old enough to sign a contract or cast a vote. And the witness has just told us, under oath, that those things which were done to him are the things that tell you best what he will do.

So it follows, does it not, that what he will do is caused by what was done to him?

The witness has no choice but to say yes. It was built on that answer. Every number it gives is that answer, worked out to two decimal places.

And then I should sit down. There is a rule among cross-examiners that you never ask the one question more, because the one question more is the one that lets the witness out. I learned it the hard way, and I have watched better men than I learn it harder. But I am not before a jury now, and you are not in a hurry, so I will ask the question I would have saved for the closing.

If what this man will do is caused by what was done to him, then what are the extra years for?

---

I want to be fair to the judge. I have known a great many judges, and most of them were not cruel men. They were men with too many cases and too little time, and the law put a terrible weight on them, and they reached for anything that would help them carry it. A number is a great comfort to a tired man. It seems to come from outside him. It does not ask him to look at the defendant and decide; it has decided already, and he has only to read it out.

But consider what the number is for. In the old days, when they hanged a man or put him away, they at least pretended it was for something he had done. They said he deserved it. I never believed in desert, and said so, but I could understand what they meant. They meant that the man had chosen evil, and the State was paying him back. That is vengeance, of course. I wrote in my book that "vengeance is the moving purpose of punishment," and I have not changed my mind, but at least vengeance looks backward, at a thing that happened.

The machine does not look backward. It does not pretend to say what the man deserves. It has no opinion on desert at all. It says only what he is likely to do, and the court adds years for that. It punishes him for the future. It sends him to prison for a crime that no one has committed yet, on the testimony of a witness who says he is the kind of man who would.

Now there is an old answer to this, and the answer is: we are protecting the public. Very well. Let us see how well the public is protected.

The same reporters, who were from ProPublica, took the scores of something over seven thousand people arrested in Broward County, Florida, in 2013 and 2014, and followed them for two years to see what they actually did. Of those the machine predicted would commit a violent crime, about one in five did. Twenty out of a hundred. Of all the predictions, counting every little misdemeanour, the machine was right about sixty-one times in a hundred. A coin is right fifty times in a hundred and does not charge a licence fee.

Then they broke the figures down, and here the witness begins to look less learned. Among those who did not go on to be arrested again, the Black defendants had been marked as higher risk forty-four point nine per cent of the time; the white defendants, twenty-three point five. Among those who did go on to be arrested again, the white defendants had been marked lower risk forty-seven point seven per cent of the time; the Black defendants, twenty-eight. So the machine was wrong about both kinds of men, but it was wrong in opposite directions, and the direction depended on the colour of their skin. It was hard on the one and easy on the other.

The company that made it said the reporters' analysis was not correct, and the statisticians have been quarrelling about it ever since, and I do not doubt that the quarrel is a learned one. I have heard a good many learned quarrels in courtrooms. I noticed that whichever side won, the men who had been scored stayed where they were.

---

You will remember that race is not one of the questions. I believe that. I do not think anybody sat down and wrote a machine to be unfair to Black men. I do not think it was malice. It was something worse than malice, because malice can be found out and named and punished, and this cannot.

The machine learned what it knows from arrests. It was taught: here are a great many men, and here is what they were afterward arrested for; now find what they had in common. And it found what they had in common. It found the neighbourhood and the father in prison and the friends who were picked up and the fights at school. But who decides where the police go? Who decides which corner gets the patrol car every night and which gets it once a month? Who decided, a generation ago and two generations ago, which part of the city a man might buy a house in, and which part he might not? Who sent the father to prison, and on what score, and on whose say-so?

I defended a family in Detroit, in 1925 and 1926, who had bought a house on the wrong street, which is to say a street where white people lived, and a mob came to the house, and somebody inside fired, and a man in the street was killed, and the doctor who owned the house, and his brothers, and the friends who were with them, were all put on trial for murder. I said to that jury, in a good many more words, that they must look at what had been done to these people before they looked at what these people had done. The machine would have scored them, I suppose. It would have found arrests in the family, after that night. It would have been perfectly accurate.

This is the thing about causes that the people who called me dangerous never understood. If you take causes seriously at all, you have to take them all the way back. You cannot stop at the man's father and say: there, that is the cause, and the cause lives in this man, so put this man away. The father had a cause too. The street had a cause. The patrol car had a cause, and the judge who read the number had a cause, and the company that built the machine had a cause, which was that somebody would pay for it. In my book I put it as a law: "given the same conditions the same result will follow forever and ever." The machine has proved it for me better than I ever could. Feed it the same conditions and it will give you the same men in the same cells, forever and ever, and call it a prediction.

---

There is something else I must say, because I spent forty years in courtrooms and I cannot let it pass.

When I was a young lawyer, there was a great fashion among learned men for finding the criminal in his body. An Italian doctor named Lombroso measured the skulls and the ears and the jaws of men in prison, and announced that he had found the born criminal, who could be told by his face. Men with university degrees believed it. It was printed in serious books. Some of it got into the courts, as such things do. It was nonsense, and it was cruel nonsense, and it was cruel in just the way you would expect: it found the born criminal, mostly, among the poor, and the foreign, and the people who were already in prison, because those were the people it measured.

Every age has its instrument for telling us that some men are made for the jail. Ours is more modest in its claims. It does not say a man is born a criminal. It says only that he has a score. But look at what is done with the score, and tell me how much difference there is.

And there is one difference that is worse. When Lombroso measured an ear, the man could at least see the calliper. A lawyer could stand up and say: the ear is an ear, and here are a hundred honest men with the same ear. When this machine makes its number, nobody in the courtroom knows how. The Supreme Court of Wisconsin said so in plain words. The court ordered that the reports must carry a warning, and the first warning was that "the proprietary nature of COMPAS has been invoked to prevent disclosure of information relating to how factors are weighed or how risk scores are determined." Another warning said that "some studies of COMPAS risk assessment scores have raised questions about whether they disproportionately classify minority offenders as having a higher risk of recidivism." That was printed on the report, and then the judge was allowed to read the report.

I would like you to think about that as if you were in the chair yourself. A witness comes into court against you. It says you are dangerous. You ask how it knows, and you are told that how it knows is a business secret, and that the business would be harmed if you found out. You ask whether it has been wrong about men like you, and the court itself tells you that it may have been. And then you are told that this is due process of law.

I have cross-examined a great many experts. I have had them on the stand for days. I never met one I could not ask: how do you know? I asked a man in Tennessee once, who was a great deal more famous than I was, how he knew the things he said he knew, and the whole country listened to him try to answer. That is the only protection a defendant has ever had against a learned witness. Take it away, and there is no learning left in the room; there is only a verdict, and a man in a uniform to see that it is carried out.

---

Now I want to turn the thing around, because I did not come here only to tear the witness down. A good cross-examination takes the other side's evidence and makes it testify for you. I have done it with doctors and with preachers and with policemen, and I mean to do it with this machine.

The machine is right about one thing, and it is the most important thing. Conduct is caused. A man's chances do depend on his father and his street and his schooling and his friends. The State has spent a great deal of money to prove what I said for nothing, and I am grateful. Let us take the confession.

If you can see the causes, you can do something about the causes. That is what we do everywhere else. When a doctor finds that a man is likely to have a heart attack, he does not lock the man in a room for six years to protect the public from his heart. He tells him what is wrong and tries to mend it. When an engineer finds that a bridge is likely to fall, he does not sentence the bridge. He looks for the weak beam. Nobody thinks it soft-hearted to mend a bridge.

So if a man scores high because he has no work, find him work. If he scores high because his friends are in trouble, give him somewhere else to stand. If he scores high because he grew up in a house where his father was taken away, then there is very likely a child in his own house now with the same score coming to it twenty years hence, and that is the place to put the money. I wrote in my book that "all punishment for the purpose of causing suffering, or growing out of hatred, is cruel and anti-social," and I was laughed at for it by sensible men. But the sensible men have built a machine that agrees with me about the cause of crime, and they are using it to cause more suffering. One of us is not being sensible.

You will say this costs money. It does. So does a prison. A prison costs more money than almost anything the State does for a man, and when the man comes out he is worse fitted to live in the world than when he went in, and the machine will score him higher for having been there. That is the wheel. The machine does not stop the wheel. It oils it.

---

I am an old man, and I have been dead some time, which gives a fellow a certain detachment. I have seen the instruments come and go. I have seen the skull-measurers and the eugenics men, who wanted to keep the wrong sort of people from having children, and got laws passed to do it. I have seen the gallows and the electric chair, which was sold to the public as a humane improvement on the rope. Every one of them was going to be scientific. Every one of them was going to take the guesswork and the passion out of punishment. And every one of them, when you looked closely, was the old passion with a new coat on.

I do not say the people who build these machines are wicked. I never said that the people who built the gallows were wicked, either. I said they did not understand what they were doing, and that if they did understand it, they would stop. I still think that. I think most people, if they once saw clearly that a man is made by the life that is put into him, would no more wish to punish him for it than to punish a child for the colour of its eyes. That is not a sentimental belief. It is the most practical belief I know. It is the only one that has ever made anybody safer.

You who sit on juries, and you who vote for the men who appoint the judges, and you who write the machines: you are not simple people, and you do not need things made simple for you. You can hold two ideas at once. You can believe that a man is dangerous and that he did not make himself so. You can believe that the public must be protected and that a cage is a poor way to do it. The machine cannot hold two ideas. It was built to give one number. But you were not built to give one number, and you should not let anybody persuade you to behave as though you were.

---

I went back over the questions on that form, the ones the reporters printed. There is the one about the father in prison, and the one about the friends, and the one about fights at school. And there is the one the man is asked to agree or disagree with: "A hungry person has a right to steal."

I do not know what answer the machine wants. I suppose a man who agrees is scored as more dangerous, and a man who disagrees as less. I have thought about it for some time, and it seems to me that I should have to agree, and that I should have to score high, and that the machine would mark me down as a risk to the community.

I have been marked down as that before. It is not the worst company a man can keep.

No further questions.
