It's That Trainees May Never Learn How to Do So in the First Place

AI's danger isn't just in experts losing the ability to reason. It's that trainees may never learn how to do so in the first place. In healthcare, there's growing concern over doctors becoming less clinically adept as they increasingly rely on AI tools.

But what about the trainees – medical students, residents and fellows – who are using these tools before they've built their own clinical judgment? The idea of deskilling implies that someone possessed an ability and then lost it. Here, the danger is not just deskilling but never-skilling.

Although a doctor who has forgotten how to reason is recoverable, one who never learned how may not be. OpenEvidence, essentially an AI chatbot for clinicians, has given this concern its most concrete form. About two-thirds of US doctors actively use OpenEvidence, asking about puzzling symptoms, drug interactions, and clinical guidelines, getting responses within seconds, anchored in the latest research.

Trainees, unsurprisingly, have also begun to use this AI tool in many of the same ways – but at a far more formative stage. For example, trainees once asked to build a list of potential diagnoses might struggle and offer an incomplete set, learning what they missed, sometimes painfully. Now, trainees can simply ask OpenEvidence and get a nearly perfect answer, complete with possibilities they might have never considered and none of the embarrassment of having overlooked them.

Repeating this answer on the wards may make the trainee look prepared and even impress the supervising doctor. However, this performance can also conceal the very deficit that training is meant to reveal: that the struggle is the point. Medical training, more than most professions, is an apprenticeship.

A student becomes a resident, a resident becomes a fellow, and a fellow becomes an attending – every step shaped by failure, uncertainty and increasing responsibility. With years of repetition and watchful supervision, the habits of clinical reasoning slowly become part of the physician's inner architecture. Technology has long shifted how people learn medicine, from advanced imaging to electronic medical records.

But AI is different, not just expanding what doctors can see but inserting itself into the cognitive machinery that training is meant to build. As these tools become more capable and the physician's role increasingly involves supervising them, experienced clinicians may have enough intuition and independent judgment to critically evaluate the machine's answers. But for trainees whose understanding of medicine is being formed alongside AI, the relationship is more fraught.

Can they really question the reasoning that shaped their own? What happens when the generation trained by AI becomes the generation responsible for catching its mistakes? With unchecked use among trainees, we risk creating supervisors of reasoning before we create reasoners.

The stakes of that question are growing: a recent study in Nature Medicine found that tools pulling from the latest medical literature, like OpenEvidence does, can be less reliable than they appear and, in some cases, less accurate than general-purpose AI chatbots. The problem of misplaced trust is already embedded in the AI that trainees are using today. To be clear, many trainees sense the trap, telling us they know that tools such as OpenEvidence can become a crutch.

But these trainees also feel stuck in an arms race: if everyone else is using AI to sound more prepared, opting out feels like unilateral disarmament. The solution, then, cannot rest on individual restraint. That is why medical schools and residency programs need to shape not just whether trainees use AI, but when.

No one can police every search on every phone, nor should they. But supervising doctors can build a simple expectation – reason first, consult AI second – and assess accordingly.
