**T**he specimen, posted to the subreddit r/ChatGPT under the heading "Chat makes anti-mammal propaganda," is a Midjourney-generated image purporting to satirise the class Mammalia. The image performs its assigned task with a kind of doomed sincerity. The figures glower. The composition obeys the conventions of mid-century agitprop—the heavy lithographic flatness, the upraised limb, the slogan one cannot quite read. Then one looks at the hands.

The hands have six fingers.

This is not a small fact. The brief, however jocular in origin, was to disparage a phylum defined by a fixed set of anatomical specifications, among them the pentadactyl limb. Five digits. The number is settled biology, settled even before biology, by every mammalian hand pressed against every cave wall in the Upper Paleolithic. The image cannot count to five. It is producing propaganda against a category whose membership it cannot draw.

There is a useful framework, borrowed from the criticism of motion pictures, in which one asks whether the work before us has made its decisions consciously, unconsciously, or not at all. Hitchcock decides consciously. A studio carpenter decides unconsciously. The third category was, until recently, theoretical. The third category has now been instantiated in software.

The image makes no decisions. It is the average of a corpus, retrieved by a prompt, rendered by a process that holds no view on hands, no view on mammals, and no view, properly understood, on anything whatsoever. To describe the result as propaganda is to mistake the mechanism. Propaganda requires a propagandist—an agent that has resolved, however cynically, to persuade. The specimen has no such agent. What it has is a tendency. The tendency, where hands are concerned, is to overproduce.

This produces the central irony, which is taxonomic. The brief was anti-mammalian. The execution exhibits the precise feature mammals reliably possess and the system reliably does not. The most mammalian thing in the frame is the error. One can stage that sentence as a joke or as a finding; it is more useful as a finding.

The defects catalogued by forensic review—extra fingers, uncanny symmetry, texture smoothness, impossible joints—are not stylistic flourishes. They are the signatures of a process that has digested some immense quantity of images of the human hand and concluded, from the digestion, that the hand is a region of the canvas where fingers happen. How many fingers happen is, to the system, a matter of indifference. The system will produce four, or five, or six, or, in well-documented cases, fingers nesting inside other fingers, like a Russian doll redrawn by someone who has heard of Russia.

A temptation, here, toward derision. The temptation should be declined, not from charity but from accuracy. Derision presupposes a target capable of being shamed. The specimen cannot be shamed. It cannot even be told that it has six fingers; the next specimen will have seven, or four, or—by a sort of statistical luck—five, and none of these results will register with the apparatus that produced them. There is no learning in the relevant sense. There is only the next request and the next average.

What the artefact demonstrates, without intending to demonstrate anything, is the limit of the satirical mode under present technical conditions. Satire requires a position. The machine has no position. It may be aimed at a target; it cannot itself aim. The brief was to mock the mammal. The execution produced an output whose most arresting feature is its failure to render the mammal correctly. The propagandist has, in the very act of composition, become its own counterexample.

One could read this as a warning about artificial intelligence and the genres it borrows. One could also read it more narrowly. A poster commissioned against a phylum has been undone by an anatomical detail belonging to that phylum. The hand has six fingers. The argument has none.

CUTLINE: Specimen: Midjourney-generated image arranged in the manner of a propaganda lithograph, depicting figures in attitudes of denunciation, with supernumerary digits on the visible hands. Recovered from Reddit, r/ChatGPT, posted by an anonymous account. The hand maligning the mammal carries one finger more than the mammal does.
