When Judging Is Shaping
The case of the thirteen-year-old in light of the implicated-observer thesis: what happens when we apply to juvenile justice the lesson we have already accepted in medicine.
Editorial — April 2026 — Part II
A previous editorial proposed an apparently sober thesis: no observation is neutral. The physician gathering data, the physicist taking a measurement, the researcher conducting an interview—all modify the system they claim to know. The thesis is easily accepted in the abstract. It becomes uncomfortable when applied to a case in which our claim to neutrality is older, more institutional, more defended. One such case is juvenile justice.
When a thirteen-year-old commits a serious crime, public debate arranges itself along a familiar axis: is he a monster to be punished, or a life to be saved? The question, like every moral dichotomy, has the advantage of being emotionally clear and the disadvantage of being philosophically ill-posed. It presupposes that the judicial system observes an act, measures its gravity, and assigns the corresponding response—as though the response were not already part of the observed system. It is not. The institutional response to a thirteen-year-old who has done harm is not a consequence of observation: it is itself observation. And observation, here, is intervention in the most literal sense.
Contemporary neurobiology—Robert Sapolsky has made it accessible in Behave and in Determined—has made evident what hermeneutics and phenomenology had intuited by other routes: the subject we observe is not a closed datum. At thirteen, the prefrontal cortex—the region responsible for impulse control, evaluation of consequences, and recognition of the other—is still under construction. It will complete its maturation around the age of twenty-five. The reward and desire circuitry, meanwhile, is already fully active. Every adolescent, biologically, finds themselves with the accelerator pressed to the floor and the brake still in the workshop. This fact neither absolves nor mitigates: it describes. But a description, in this field, has immediate consequences.
If the observed system is still plastic, then every institutional act that touches it modifies it. The punitive frame is not a measurement of harm inflicted: it is a further neurobiological event in the history of that brain. To hand a thirteen-year-old a final identity—“criminal,” “monster,” “lost”—is not to record an existing truth but to help produce one. Neural plasticity means that the institution that judges participates physically, not only symbolically, in the formation of the subject it claims to evaluate. It is Heisenberg’s lesson translated from microscope to tribunal.
Here the thesis of the previous editorial recovers its full force. In medicine, over the course of a century, we have built a device—informed consent—that makes the interventional character of the clinical act explicit. It is not a formality: it is the procedural recognition that the physician participates in the patient’s condition merely by observing it. Juvenile justice has developed no analogous device. It continues to present itself as a neutral recorder of facts, treating its own response as the inevitable effect of the gravity of the act—rather than as a cause that helps determine the subject it judges. This is, in the editorial’s terms, a form of opaque authority: competence that does not declare its position within the system.
The question, then, changes in nature. It is no longer “monster or child to be saved”—a dichotomy that presupposes neutral observation of a closed subject. It is rather: what intervention do we wish to exercise, knowing that we are intervening regardless? What institutional frame reduces overall suffering—of the victim, of possible future victims, and yes, of that boy whose prefrontal cortex, for biological reasons he did not choose, is still an open construction site?
The temptation to resist is the same one the editorial has already named: invoking “the good of the many” to compress the complexity of the single case. The victim exists, the harm is real, the need for recognition is non-negotiable. But separating recognition from punishment—two things our culture has confused for millennia—is the only way out of the fiction of the neutral observer. Recognition must be honored: without it, there is no justice for those who have suffered. Punishment, however, as an act that claims to measure guilt while presupposing a freedom of will more solid than biology allows, can be interrogated. Not abolished—containing those who are dangerous remains a necessity—but interrogated in its claim to be deserved rather than useful.
This is not a comforting conclusion. It does not offer victims the symbolic prize of full punishment, and it takes from all of us the illusion that we are clear authors of ourselves and clear judges of others. But it is consistent with the thesis we have assumed: every act of knowing is also an ethical act, and every gaze upon another is already a hand placed upon them.
Adult justice—the real thing—begins when we accept that to judge is not to record: it is to shape. And that the responsibility of those who shape does not end at the signing of the sentence.
