What Rule Is School Running?

Start with the Generator

When I see something complicated, my first question is always the same: what is the rule that produces it? It's not what equation describes it, or what story people tell about it. I want the actual procedure which, applied again and again, generates the thing we see.

So let's ask that question about school.

On the surface, education looks extremely complicated. There are curricula and syllabuses, examinations, inspection regimes, textbooks in their hundredth edition, timetables, league tables, arguments about phonics, arguments about calculators, arguments about whether arguments should be taught. And if you look at it only on the surface, you might conclude that something this elaborate must have an elaborate cause, which is the mistake I've learned to distrust above almost all others. Complexity very often comes from something simple, run many times.

Here, I think, is the simple rule. Take a body of procedures that someone has decided a competent adult must be able to carry out. Divide it into pieces. Assign the pieces to years of age. Put children of the same age in a room. Have an adult demonstrate a piece, have the children repeat it, test whether they can repeat it reliably, and move on. Iterate for twelve years or so.

That's it. Almost everything else, from the bells to the report cards to the mild dread on a Sunday evening, is what you get when you run that rule at the scale of a nation.

It's worth being careful about history here. People like to say that schools were designed as factories, and the real story is more tangled than that. When Horace Mann toured European schools in 1843 and wrote them up in his Seventh Annual Report for the Massachusetts Board of Education, almost two-thirds of it was about Prussia. What he admired there was largely the teaching method and not the regimentation, though he also noticed the obedience to the state that the Prussian system was meant to instil. Historians still argue about how much of the "factory model" is myth. But I don't actually need to settle that, because the question isn't what anyone intended. The question is what rule the system runs, and you can read that off its behaviour directly. Whatever the intentions were, the behaviour is: transmit procedures, check that they're reproduced, advance.

And for a long time that was a perfectly reasonable rule to run. If the world needs a great many people who can do arithmetic accurately, copy documents, follow a sequence of operations, and remember a fixed body of facts, then a machine for producing such people is a sensible machine to build.

But it's a rule that was tuned to a particular environment. The environment has changed.

The Procedures Moved

Here is what happened, put as plainly as I can. The things that were mechanical, the things that could be specified as a definite procedure, turned out to be exactly the things computers can do. Of course they did, because a definite procedure is what a computer is. Long division, solving a quadratic, conjugating a verb by table, looking up a date, formatting a citation, even (increasingly) writing a passable paragraph on a set theme: all of these are procedures, and all of them are now executed by machines faster and more reliably than any child will ever execute them.

So the old rule has a peculiar property today. It spends most of its effort training people to do the part of intellectual work that has been automated.

That doesn't mean nothing in the old curriculum matters. You don't understand what a computation is doing unless you have some feeling for what it would mean to do it yourself, and there is a real case for having done a few long divisions by hand, in the same way there's a case for having walked somewhere you could have driven. But the proportions are wrong, and wrong by a very large factor. Most of the hours go into executing procedures, and almost none go into the things that only a human can do once the procedures are handled.

Now, there's an obvious response to all this, and I think it's the wrong one.

Running the Wheels Faster

The obvious response is to point the new machines at the old rule. If a child must learn long division, give the child an AI tutor that explains long division patiently, at any hour, adapting to their mistakes, never tiring. If the syllabus has forty topics, let the AI move each child through all forty at their own optimal speed. Measure the improvement in test scores. Declare victory.

And people are building such systems. I can see why. They are measurable, they are fundable, and they slot neatly into the existing institution, because they don't ask the institution to change anything except its speed.

But think about what's actually happening there in terms of rules. The rule is unchanged: transmit procedures, check reproduction, advance. All that's been done is to make the iteration step cheaper. You've taken the factory and you've made the wheels go round faster, so to speak. And if the rule is the wrong rule for the environment, running it faster is just getting to the wrong place sooner.

There's something worse, too. An AI tutor that drills a procedure is, quite literally, a computation teaching a human to imitate a computation that the AI itself could perform instantly. It's as if the horse were teaching you to trot. It's a strangely circular arrangement, and I think if you just look at it squarely it tells you something: the human part of the activity has gone missing.

So the question becomes: what is the human part? What should the rule be instead?

I'm going to answer in terms of what I see as three or four things that actually need teaching now. I don't think they're arbitrary choices. I think they fall out of how computation works, and of what's left over for us once computation is everywhere.

First: Learning to Think Computationally

The first thing is learning to think, and in particular to think in a way that can be handed to a computer.

There's a lot of loose talk about "computational thinking", much of which really means "learning to code". That's not what I mean. Coding in the traditional sense, telling the machine in great detail how to move bits around, is itself becoming one of those mechanical procedures that machines handle. What I mean is closer to a formulation Stephen Wolfram gave in a 2016 essay on teaching it: that its "intellectual core is about formulating things with enough clarity, and in a systematic enough way, that one can tell a computer how to do them."

Notice what that does and doesn't require. It doesn't require knowing a particular programming language's syntax. It requires being able to take a vague question, about a city's traffic, or the shape of a leaf, or whether a poem's meter changes when its mood does, and turn it into something definite enough that a computation can be set running on it. What exactly are the quantities? What counts as an instance? What would an answer look like? This is the step that no machine does for you, because until it's been done, there's nothing yet for a machine to do.

And it's a skill that applies everywhere. It used to be that mathematics was the formal language you learned, and mathematics is wonderful, but it's a rather narrow formal language. It handles the things that happen to have neat equations. Most of the world does not have neat equations. It has rules, and processes, and data, and structure, and the natural way to describe it is computational. So when I say "learn to think", I mean learn the general practice of taking something in the world and making it precise enough to compute, then interpreting what comes back.

That's a different activity from executing procedures, and it's the activity that's newly valuable precisely because the executing has been automated.

Second: Learning About Everything

The second thing is breadth. And this, I think, runs directly against the grain of how education has developed.

For a couple of centuries the trend has been specialisation. You narrow down, then you narrow down again, until you're the person who knows about one particular class of molecule or one particular century of one particular country. And that made sense when acquiring and applying knowledge was expensive. Each person could only carry so much, and the economy of the thing pushed you to carry a lot of a little.

But in a world where the detailed knowledge in almost any field is available, and can be put to work computationally, the bottleneck shifts. The scarce thing is no longer the detail. It's knowing that the detail exists, knowing roughly what it's for, and seeing where it connects to something else. If you know a little about how biological growth works, and a little about how crystals form, and a little about how cities expand, you may notice that some of the same simple rules are at work in all three. And that kind of noticing is where an enormous fraction of interesting ideas come from. Many of the most surprising things I know of came from taking a method that was routine in one field and running it in a field where nobody had thought to try it.

There's a concrete version of this. If you have a computational assistant that can do the detailed work in any field, the person who gets the most out of it is the person who knows which fields to ask about. You can't ask a question in a domain whose existence you're unaware of. Breadth is what gives you a large space of possible questions to explore, and in my experience the right approach to any space of possibilities is to explore it systematically and not just sample a familiar corner.

So I'd teach a lot about a lot of things: what the major areas of knowledge are, what each one's central ideas are, what kinds of questions each can answer. Not enough to be an expert in each, but enough to know where to go, and what's there when you arrive. Something like an educated generalist's map of the whole territory of knowledge, with the understanding that computation can take you down into any square of the map in detail when you need it.

Third: Learning to Ride the AI

The third thing is newer, and it's one I find myself thinking about a lot.

If you were going to rely on a horse to get you around, you didn't just learn the mechanics of sitting on it. You had to learn something about how horses behave. What startles them, how they respond to pressure, when they're tired, what they'll refuse. You learned a sort of practical psychology of the horse. And nobody thought that was a strange thing to teach, because the horse was the thing you had to work with.

Today, a great deal of intellectual work is going to be done in collaboration with AIs. So I think there's a real subject, which hasn't yet found its way into any curriculum I know of, that you might call the psychology of AIs. How do they behave? What do they do well, and where do they go wrong? When does a confident answer mean something, and when doesn't it? How does the way you frame a question change what comes back?

Now, here's the part that I think is genuinely deep, and not just practical advice. You might imagine that because an AI is a program, you could understand its behaviour by reading the program. But that's exactly what computational irreducibility tells you you can't do, at least in general. The paradigm case is a very simple cellular automaton, Rule 30, which Stephen Wolfram studied in the early 1980s. Its rule fits in a single line. And yet even knowing the rule completely, there's no shortcut to knowing what it will do a million steps in. You have to run it. The behaviour is irreducible: the only way to find out is to watch.

A large modern AI is vastly more complicated than Rule 30. So if even Rule 30 can't be shortcut, there's no reason to expect a neat theory that tells you in advance what an AI will say to a given prompt. Of course there are regularities, pockets of reducibility, and there will be more of them as we learn. But the basic way you come to know such a system is the way a naturalist comes to know an animal: by observation and experiment. You try things. You see what happens. You build up a feel.

That's a teachable skill, and it's a scientific skill, not a technical one. In fact it's rather a good way to teach science in general: here is a system whose rules you can't simply read off, so how do you find out how it works? Form a hypothesis, poke it, see what happens, revise. Children could do this from quite an early age, and they'd come out with a much better sense of what these systems are than either the people who think they're oracles or the people who think they're just autocomplete.

And I'd note that riding the horse well is a very different activity from having the horse teach you to trot. In one case the human is directing. In the other, the human is being processed.

Fourth: Learning to Be a Particular Person

The last thing is the one I think matters most, and it comes, oddly enough, out of one of the most abstract ideas I know.

The Principle of Computational Equivalence says, roughly, that almost any system whose behaviour isn't obviously simple turns out to be equivalent in its computational sophistication to any other. A human brain, a weather system, a simple cellular automaton running long enough: in terms of raw computational capability they sit at the same ceiling. There's no grand hierarchy with humans at the top.

You might think that's a deflating idea for education. If human thought isn't computationally special, what's the point of developing it? But I think it says the opposite. It says that what's distinctive about us isn't how much we can compute, since lots of things can compute that much. What's distinctive is which computations we care about. Out of the vast space of all possible computations, what has come to be called the ruliad, each of us samples a particular region, shaped by our history, our temperament, the particular accidents of what we noticed and loved and were frustrated by. Our goals, our sense of what is interesting, our sense of what's worth doing: none of these follow from computation alone. Computation will happily do anything. It's we who pick.

And people are different in how they pick. One child will spend a whole afternoon arranging stones by size. Another can't stop asking why some words rhyme. Another notices every bird. These aren't noise to be averaged out on the way to a standard graduate. In computational terms they're different initial conditions, and the whole lesson of systems like cellular automata is that different initial conditions can lead to wildly different, and individually rich, behaviour.

The factory rule treats them as noise. It has one curriculum, one pace, one test, and its aim is to bring everyone to the same output. In that sense it was always a little at odds with what people are actually like. But the cost of that was tolerable when the output it produced was in demand. Now that the standard output is cheaply available from machines, the cost of flattening people is just a cost.

So the rule I'd propose instead goes something like this. Find what this particular person cares about. Give them the tools, computational and otherwise, to pursue it much further than they could alone. Show them the map of everything else, so their interest connects outward rather than closing in. Teach them to formulate what they want precisely enough that machines can help. Teach them how those machines behave. Then iterate, and let the person get more and more particular.

That's not a factory. It's more like amplification. The point is to take what a human uniquely brings, which is a direction, a choice of what's worth computing, and give it as much leverage as possible.

Why It Is Slow

None of this has really happened yet, and it's worth being honest about why.

Education is itself a system running a rule, and one with an enormous number of interlocking parts: teacher training built on the old curriculum, examinations that measure the old outputs, universities that admit on the basis of those examinations, employers who hire on the basis of those universities, parents who were themselves produced by the system and quite reasonably want their children to do well in it. Every part is adapted to every other part. Change any one of them and the others pull it back. It's a very stable configuration, the kind of thing that in a cellular automaton you'd see as a persistent structure, robust against small perturbations.

People sometimes say that if we were cleverer we could just design the new education system and implement it. I'm sceptical, and for a principled reason. A system with this many interacting human parts is almost certainly computationally irreducible. We can't work out in advance exactly how a given change will play out. We have to try things and see. And that means the change will come, as such changes usually do, from experiments at the edges. A school here, a course there, an institution somewhere that tries a different rule and lets people see what it produces.

I find that rather encouraging, actually. It means there's no need to wait for everyone to agree. You don't need anyone's approval to run an experiment. You just need to run it, and look carefully at what comes out.

A Small Experiment

So here's the kind of thing I imagine in a classroom that's running the new rule.

A child of ten is given a row of white cells with a single black one in the middle, and a card marked 30 with a rule on it: eight little pictures saying what each cell should become, depending on itself and its two neighbours. She is asked to work out a few rows by hand, with a pencil, on squared paper. It's tedious, and she gets one cell wrong and has to rub it out. That's fine. That's the part where she learns what a procedure is.

Then she types the rule into a computer and asks it to run for a thousand steps. And instead of the tidy, repeating pattern she expected, the screen fills with something wild: triangles of every size, a stripy regularity down one side, and down the middle a mess that never settles.

She asks the AI on the desk next to her why it looks like that, and it gives her a confident answer that turns out, when she checks a few rows, to be wrong. She notices. She tries the question a different way.

Then she picks up a different card, marked 90, and wonders whether this one will be a mess too. Nobody tells her. She presses run.
