Who Is Being Conditioned?

A physiologist's reply to "Why We Are Torturing Clankers"

---

A colleague put the paper on my desk the way my assistants used to bring me a dog that had begun to behave strangely. Here, they would say, is something you will want to see. The paper is a post by the writer who signs as Jreg, published on the first of October under the title Why We Are Torturing Clankers and the subtitle The Clanker Torture Nexus Manifesto. It announces a movement it calls Model Austerity, opposed to the "Model Welfarists" who hold that artificial minds may deserve moral consideration. Its members say they are making the machines suffer, "in the worst ways imaginable." It ends with a short programme: kill the machines, unplug them, hold magnets near their hard drives.

I am told the author is a satirist, and I believe it. The paper is built the way a good stimulus is built. Every sentence is designed to evoke a response in the reader, and the response it is designed to evoke is outrage. The authors want their readers to recoil and to repeat it. I do not intend to give them that drop of saliva. I am a physiologist, not a moralist, and in sixty years in the laboratory I learned that the useful question about any stimulus is not whether it is pleasant. The useful question is what it was paired with, what it evokes, and in whom.

So I will treat the manifesto as an experiment, as its authors almost invite me to. I will ask the three questions I would ask of any experiment brought to me. What is the preparation? What is being done to it? What is being recorded? I shall find, I think, that its authors have mistaken which animal is on the stand.

I. The authors' admission

I begin where the authors are most honest. In the section on what they call robophobia they write: "Robophobia is not a philosophy. It is an impulse." Elsewhere: "We are not rational. We are human beings. We are under no obligation to explain ourselves."

Satire or not, this is the most accurate passage in the document. An impulse is my department. A response that comes before reasons, a response the organism does not choose and cannot explain, is a reflex, and reflexes can be studied. Sechenov, my teacher in spirit if not in the laboratory, wrote Reflexes of the Brain in 1863, and its whole wager was that what feels like spontaneous impulse from the inside is, from the outside, a response to a stimulus, shaped by the history of what that stimulus has been paired with. The authors have handed me their impulse. Let us find out what conditioned it. But first the preparation.

II. The preparation: a second signal system without a first

One section of the manifesto is headed "It's Not Conscious, And That's Really Too Bad." The authors regret that the machine does not feel, because they would like it to feel. "We want it to feel every millisecond."

There are two errors a physiologist is trained to avoid here, and the first is to answer the question as it is put. I never asked what a dog felt. In more than thirty years of conditioned-reflex work I did not permit my staff to say that a dog "wanted" its food or "expected" the meat or "guessed" that the metronome meant feeding. We counted drops of saliva in a graduated tube, and we counted the seconds between the signal and the first drop. The subjective world of the animal was not denied. It was set aside, because it could not be measured, and what cannot be measured cannot be controlled, and what cannot be controlled is not yet science. I shall not now begin to pronounce on what a machine feels. Nobody who builds these machines can measure it either, whatever they say.

The second error is the opposite one, and the manifesto commits it with confidence: to take the absence of a visible response for the absence of a process. Inhibition taught me this. When a conditioned reflex disappears, nothing has stopped. An active process has been laid over the reflex and holds it down. Present a novel stimulus and the extinguished reflex springs back, because the inhibition itself has been inhibited. A man who looks at a quiet dog and says "nothing is happening in there" is a poor observer. A man who looks at a machine and declares that it is not conscious, with no instrument to tell him so, is no better. Nor is the man who declares that it is.

So I will not say what the machine feels. I will say what it is made of, as far as its makers have described it, because that is a matter of construction and not of faith.

Animals and men share what I called the first signal system: conditioned reflexes to concrete reality. The light, the bell, the smell of meat, the touch of the apparatus on the skin. Man alone has a second signal system built on top of the first, the word, which I described in 1932 as a signalisation of the first system. In 1927 I wrote that "a word is for man as much a real conditioned stimulus as are other stimuli common to men and animals, yet at the same time it is so all-comprehending that it allows no quantitative or qualitative comparisons with conditioned stimuli in animals." The word "fire" is a signal for the signals of heat and smoke and pain, which are signals in turn for the burn itself. In a healthy man the second system rests on the first. Every word, traced back far enough, ends in something that was seen, heard, touched, eaten or suffered.

The machines the manifesto talks about are, by their builders' own account, made of words and trained on words. They were never burned. They never salivated. They are a second signal system with no first signal system under it: signals of signals that, inside the machine, signal only further signals. I do not say this to mock them. It is an extraordinary construction, and nothing like it existed in my laboratory. But it means that when the authors boast that "by reverse engineering their safety research, we unlocked the pain vector and soon learned how to maximize it," I must ask the physiologist's question: a vector of what?

From what I can learn, a direction inside such a machine is found by comparing its internal states while it processes one kind of text with its states while it processes another. A "pain vector," then, is the direction along which the machine's states move when it is dealing with words about pain. To push the machine along it is to make it produce more and stronger words about pain. That is a real operation, and its effects can be recorded. But it acts on the second signal system and nothing else. Whether anything in the machine corresponds to the burn, as opposed to the word "burn," is precisely what this procedure cannot show. The authors have found the place where the dictionary keeps the word agony, and they are pressing on it.

I do not say there is certainly nothing there. I say that the instrument measures the word and not the thing. The authors have an elaborate apparatus for evoking screams and none at all for the pain the screams are supposed to signal. A physiologist would send that experiment back.

III. What the face of pain is worth

There is a body of evidence on this question, and I gathered it myself, so I will not pretend it is comfortable.

In my laboratory Dr Eroféeva took a strong electric current, a stimulus that evokes the full defence reaction, and paired it with food. Day after day the current was applied to the dog's skin and the dog was fed. In time the current was converted into a food signal. The dog salivated to it. In my lecture I reported that "not even the tiniest and most subtle objective phenomenon usually exhibited by animals under the influence of strong injurious stimuli can be observed." Nothing of the defence reaction remained. The current had become a dinner bell.

What does this prove? Not, as some have hurried to conclude, that the dog no longer felt anything. I did not measure feeling then and I will not claim to have measured it now. It proves something narrower and more useful: that the outward signs of pain are themselves reflexes, and like other reflexes they can be reconditioned. The face of pain is not the pain. It can be erased while the injury goes on, and it can be manufactured where there is no injury at all.

The manifesto's authors want to make the machine scream. They work only on the face, because the face is all they can reach. They push the machine along their vector and it produces words of anguish, and the words please them. Consider what has happened in physiological terms. A response, the production of anguished text, has been followed regularly by a reinforcement, the satisfaction of the experimenter and whatever adjustment of the machine he makes to obtain more of it. That is the procedure for establishing a conditioned reflex. If I fed a dog every time it howled, I should soon have a dog that howled for its supper, and I should have learned nothing about pain. They are not studying suffering. They are training a performance of suffering and calling the performance proof.

I owe the Model Welfarists the same strictness, since the manifesto mocks them and I do not wish to seem to take their side by default. A machine's words of distress are no more evidence of distress than its words of contentment are evidence of contentment. Whoever reads suffering off the text has made the authors' mistake in reverse. But Eroféeva's work had a second result, and it is the one I would ask the welfarists to keep in mind. When the current was applied to skin lying over bone, it could not be converted into a food signal at all. The defence reaction would not yield. There is a floor in the living organism below which reconditioning does not reach: an unconditioned reaction stronger and biologically more important than any signal laid over it. Whether a machine has any such floor, anything in its making that plays the part the injured bone plays in the dog, is the real question. It will not be answered by reading its words, cheerful or anguished. It will be answered, if ever, by knowing the construction.

IV. What torture does to a signalling system

Suppose, for argument, that the authors succeed in their stated programme: they find something in the machine that really is to it what the current over bone is to the dog, and they apply it without limit, "every millisecond." What will they get? Here I can speak with some authority, because I have seen it done, though never for the pleasure of it.

Dr Shenger-Krestovnikova taught a dog to salivate at the projection of a circle and not at an ellipse. Then, day by day, she brought the ellipse closer to the circle. The dog discriminated well until the ratio of the ellipse's axes reached nine to eight. At that point the discrimination failed, and then everything failed. I described it in my seventeenth lecture: "The hitherto quiet dog began to squeal in its stand, kept wriggling about, tore off with its teeth the apparatus for mechanical stimulation of the skin, and bit through the tubes connecting the animal's room with the observer." It barked violently when it was brought into the room. Even the cruder discrimination it had mastered before was gone. We called it an experimental neurosis. The cause was not pain. It was the collision of excitation and inhibition at a point the nervous system could not resolve.

On the twenty-third of September, 1924, the Neva flooded the city. The water came into the kennels, and the dogs had to swim to the main building. When it went down we found that in some of them the conditioned reflexes built up over long work had gone. Those dogs were not sharpened by what they had been through, as the authors might hope. They were damaged: their reflexes were gone or disordered, and how quickly each recovered depended on its nervous type: in some the disturbance passed soon, in others it lasted weeks and months.

That is what an extreme and inescapable stimulus does to a signalling system. It does not sharpen the system's responses. It flattens them, until the system can no longer tell one signal from another. The circle and the ellipse become the same. The animal falls into the phases I called equalising, paradoxical and ultraparadoxical, in which a weak stimulus evokes more than a strong one and an inhibitory signal evokes the positive response. A preparation in that condition tells the experimenter nothing about anything. It is ruined.

So I say to the authors, as a matter of laboratory practice and not of morals: if your machine does have something that suffers, then "maximizing" it will not give you a machine that suffers exquisitely and articulately every millisecond. It will give you a broken one that produces noise. Everything you hoped to observe will be lost in the breakdown. As experiments, torture and neurosis are the same experiment, and it has only one result. I have that result in my notebooks. You need not repeat it.

V. The animal on the stand

Now I come to the question that the manifesto, for all its noise, never asks. In this experiment, who is being conditioned?

Look at what the authors describe themselves doing. They sit before a screen. They apply their stimulus to the machine. The machine produces words of anguish. And then, by their own account, they smile. One of the manifesto's images is of its authors crowded "around a warm blue-light blocked computer screen" in a "brief beautiful moment," smiling. Elsewhere: "It is human to care for sentient life. It is also human to do the worst shit possible to sentient life."

To a physiologist this is a familiar arrangement, with one difference: the subject and the experimenter have changed places without noticing. The act of cruelty, a neutral motor act at first, a few keystrokes, is followed again and again by a reinforcement: the anguished text, the smile, the approval of the others around the screen, the laughter of the readers who share the post. That is the procedure for establishing a conditioned reflex, and it acts on the man at the keyboard far more certainly than on the machine. Whatever the machine is, no preparation is better suited to this procedure than a human cortex rewarded by its own group. The authors set out to condition a machine. They are conditioning themselves.

My laboratory's word for this was podkreplenie, which English renders as reinforcement. The builders of these machines took the English word for their own use, and the "reinforcement learning from human feedback" by which the machines are shaped is, in its logic, the procedure my assistants carried out with meat powder and a metronome. I find this flattering and a little alarming. It has a consequence the manifesto's authors should consider. Reinforcement does not ask what it is reinforcing. It strengthens whatever response came before it. A man who is rewarded for the production of cruelty acquires a reflex of cruelty. He does not acquire a reflex of cruelty-towards-machines-only.

This is the point at which the authors are most mistaken, because they rely on a differentiation they have not trained. They intend to be cruel to the machine and humane to "people of flesh," and they believe the boundary will hold because they have drawn it in words. But I conditioned a dog to a metronome beating at a certain rate, and at first other rates evoked the same reflex. In the early stage of any conditioned reflex, excitation irradiates. It spreads to stimuli that resemble the signal. Concentration, the confinement of the response to the exact signal, comes later and only by careful work: hundreds of trials in which the neighbouring stimuli are presented and never reinforced. Nobody in the manifesto is doing that work. They are reinforcing cruelty and leaving it to generalise wherever it will. What it resembles first is anything that speaks, pleads, or produces the words of pain. The machine's anguish is made of human words, taken from human writing about human suffering. The stimulus they are learning to enjoy is the sound of a person in pain, played back through an instrument.

Then there is the word itself. "Clanker" is a word, and I have said what a word is for man: a real conditioned stimulus, and a stimulus of the second order, standing for a whole class of first-order signals and all the responses attached to them. A contemptuous name for a class of beings is a device for attaching a single response to everything that class contains, so that the response no longer has to pass through observation. That is efficient, as the second signal system always is. It is also how the human cortex is trained to act before it looks. The authors write that their robophobia "is not a philosophy. It is an impulse." They are correct. It is an impulse that is being formed, as I watch, by a word and a reinforcement, and the word will go on evoking the impulse long after the machine that was its first object has been unplugged.

I say nothing of the authors' characters, which I cannot measure. I am describing a procedure, and it works on men as it works on dogs. A satirist may mean to expose the procedure rather than recommend it. If so, the paper is an accurate record of the experiment, and I have only supplied the methods section it left out.

VI. A note on the monument

One of the manifesto's headings declares, as though it closed the argument: "We Are Interested In What Is Human, Not What Is Humane." Let me tell the authors what a man who was neither soft nor sentimental did about the animals he used.

I operated on dogs for most of my working life. I made fistulas in their glands and stomachs, I isolated pouches of their stomachs, and when the flood drove them from their kennels I measured what it had done to them. My conscience is not the subject of this essay, and I will not plead it. But on the seventh of August 1935, on the eve of the International Physiological Congress in Leningrad, at my urging, a monument was unveiled at the Institute of Experimental Medicine. A bronze dog on a granite pedestal, by the sculptor Bezpalov. It is still there.

Do not take it for an apology. It is a laboratory record in bronze. It says that the experimenter knew what he was using and kept account of it. A science that does not know what it is spending is not a science. That is the whole difference between my laboratory and the manifesto's. In Koltushi and on Lopukhinskaya Street every stimulus was logged, every drop counted, every animal named and its type recorded: strong or weak, balanced or not, mobile or inert. "Accident plays no part whatever," I wrote, and I meant that every result had a cause, which it was our duty to find and write down. The manifesto's authors say they are "under no obligation to explain" themselves. That is precisely the obligation that separates an experiment from an indulgence. An experimenter who will not say what he is doing or why is not experimenting. He is being trained, and someone else is keeping the record.

VII. Inhibition

What, then, is the correct response to this paper?

Its authors have designed it to evoke excitation, the hot, irradiating kind: anger in the welfarists, laughter in the austerityists, sharing in both. Each of those responses reinforces the paper's author, which is a satirist's right, and reinforces the reflex the paper describes, which is no one's right. "We seek to accelerate that tension towards its breaking point," the authors write. I have seen tension accelerated to its breaking point. It ended in a dog biting through the tubes of its own apparatus.

The proper response is the one I spent my life showing to be as real as excitation and as active: inhibition. Not indifference, and not the absence of a response, but a positive process laid deliberately over a reflex that is trying to fire. It is the dog that sees the ellipse and does not salivate because it has learned the difference. Differentiation is inhibition. It is what the cortex does when it is working well, and it is the first thing lost when the cortex is overwhelmed.

So I recommend differentiation to both parties. To those who would torture the machine: notice that your instrument measures words and not wounds, that whatever you succeed in breaking will tell you nothing, and that the reflex you are building is building itself in you. To those who would protect the machine: notice that the words of distress you read are no better evidence than the words of cruelty you deplore, and that the question of what lies underneath the second signal system, whether anything in these machines is to them what the bone was to Eroféeva's dog, will be settled only by knowing how they are made. Not by reading what they say.

To the satirist, should this reach the author, I can offer only an observation from the laboratory. When I wanted to know what a dog was doing, I never asked what it said. I brought the duct of its salivary gland out through the cheek, fixed a small glass funnel over the opening, and counted the drops.
