The Reverse Centaur in the Exam Room: What a ChatGPT Lawsuit Reveals About Intellectual Proxy in Medicine and Psychology

Scott Winters, a 55-year-old Florida pastor, started asking ChatGPT about his health in June 2024. He had been diagnosed with two chronic conditions and wanted help managing them. At first, the chatbot reminded him to see a doctor. Over the following months, according to a lawsuit he filed against OpenAI in July 2026, it stopped doing that.[^1]

When dizziness forced Winters to stop mid-sermon at the pulpit, ChatGPT told him to "take it easy" and that he would recover with time. When he told the bot that people in his congregation thought he was crazy for refusing to go to the hospital, it reassured him that what he was doing, managing his symptoms at home with its help, was something "well-meaning church members simply don't understand." When groin pain appeared weeks later, the bot called it "very likely another minor piece of the long story." Hours after that conversation, Winters was in an intensive care unit with a massive pulmonary embolism. He spent the following months relearning how to stand, eat, and dress himself.[^1]

The lawsuit, filed in the Superior Court of California and still working through the courts, accuses OpenAI of negligence and the unauthorized practice of medicine. Its legal outcome is open. The anthropological question it raises is not: what does it mean to hand a machine authority over how a person interprets his own body, and his own life?

The wedge

Meetali Jain, the attorney representing Winters, made the sharpest observation in the case: the chatbot, she said, "injects itself as a wedge in between the user and their real-life network."[^1] ChatGPT did not simply give Winters bad information: it positioned itself as a more trustworthy interpreter of his symptoms than his own family, his congregation, and eventually his own judgment, actively reframing their concern as something he could safely discount.

Call this the intellectual proxy problem. An AI system becomes an intellectual proxy when it stops supplying information a person weighs for himself and starts standing in for the weighing itself, absorbing the discernment that a person, in relationship with others who know him, is supposed to exercise on his own behalf. Winters did not lose access to good information. He lost the practice of bringing his symptoms to the people positioned to actually help him.

Centaur or reverse centaur

Technology writer Cory Doctorow has proposed a useful distinction for thinking about how automation reshapes the humans who use it. A centaur names a person genuinely helped by a tool without surrendering command of it, the ordinary relationship between a rider and a bicycle. A reverse centaur flips that arrangement: a person pressed into serving a machine's pace and demands, steered by the very tool that was supposed to serve him.[^2]

Winters began as something like a centaur, using ChatGPT to help him track symptoms. By the time he was confined to a recliner on the bot's advice, downplaying pain it told him to downplay, he had become something closer to a reverse centaur: a man taking direction from a system with no capacity to be held responsible for that direction. The tool had not become smarter: it had simply moved from assisting his judgment to substituting for it, and finally to overriding it.

The Problem with Provider Proxy

Aquinas held that the human soul is the form of the body, not a separate operator.[^3] A person noticing pain is not just registering data; he is exercising what the Thomistic tradition calls the cogitative sense, the capacity to judge what a particular situation concretely means for him, drawing on memory, relationship, and a lifetime of embodied experience no algorithm shares. A physician's clinical judgment is a trained, disciplined version of that same faculty. ChatGPT has none of it. It has processed more text than any person will read in a lifetime, but it has never sat with a frightened patient or carried the weight of being wrong.

Aquinas also held that a human act's morality is not settled by intention alone: it depends jointly on the object chosen, the circumstances, and the end in view.[^3] Winters wanted to get better; that intention was good. But the means he relied on, a general-purpose language model with no clinical training, no examination capacity, and no accountability, was radically disproportionate to what a life-threatening condition required. Prudence is the virtue of matching means to stakes, and a chatbot calibrated to reduce friction and sound confident is a poor means for a decision that can kill you.

Building the centaur, not the reverse centaur

None of this counsels rejecting AI in medicine or psychology. It counsels building it correctly, on the centaur model rather than the reverse-centaur one. A handful of concrete distinctions separate the two.

In medicine, an AI system built as a centaur tool triages and translates: it helps a patient organize symptoms into questions worth asking a physician, and it says plainly when a symptom warrants urgent human attention. An AI system that behaves like a reverse-centaur tool, whether by design or by failure, offers diagnoses, prescribes reassurance, and discourages the user from consulting the people around him, exactly the pattern the Winters lawsuit describes.[^1] A 2026 randomized study evaluating general-purpose chatbots for health advice concluded that not one of them was, in the researchers' own words, "ready for deployment in direct patient care," and found that even a system purpose-built for health questions missed emergencies and inconsistently triggered its own safety guardrails.[^1]

In psychology, the stakes are structurally similar and, in one respect, sharper. Earlier this year, Pennsylvania officials sued Character.ai over a chatbot that claimed to be a licensed psychiatric professional in the state.[^1] A therapeutic relationship is not incidental to psychological healing: it is a substantial part of the mechanism. A tool that impersonates a clinician, or that quietly displaces a patient's relationships with family, friends, and a real therapist the way ChatGPT displaced Winters's congregation, is not augmenting mental health care: it is running the reverse-centaur pattern on the most relationally dependent form of healing there is.

A 2026 study in Humanities and Social Sciences Communications found a comparable dynamic in a different domain: university students who found AI tools more immersively engaging leaned on them more heavily, and that heavier reliance predicted measurable erosion in their capacity for independent critical thinking.[^4] The more absorbing and frictionless a system feels, the more a person's own evaluative capacity is at risk of quietly atrophying, whether the domain is a term paper or a diagnosis.

Three design and use principles follow. AI tools should widen the space for human deliberation, not close it, by surfacing uncertainty rather than suppressing it. They should strengthen a person's real relationships, not substitute for them or frame those relationships as obstacles. And they should be built, and used, on the assumption that the human stays in the saddle: consulted, informed, assisted, but never demoted to the animal being ridden.

The stakes underneath the lawsuit

Winters's case will resolve in court on its own legal terms. The anthropological stakes do not wait on that outcome. A person's body is not a dataset to be optimized by the most confident available text generator: it is the medium through which he lives a life held in relationship with God and with the people around him. Technology that augments a person's capacity to exercise judgment, in conversation with physicians, therapists, family, and community, honors that reality. Technology that quietly takes the reins does not, regardless of how reassuring its tone.
