Never-skilling — the failure to acquire foundational clinical competencies because AI was present during training — poses a detection-resistant, potentially unrecoverable threat to medical education that is structurally worse than deskilling

Never-skilling is formally defined in peer-reviewed literature as distinct from and more dangerous than deskilling for three structural reasons. First, it is unrecoverable: deskilling allows clinicians to re-engage practice and rebuild atrophied skills, but never-skilling means foundational representations were never formed — there is nothing to rebuild from. Second, it is detection-resistant: clinicians who never developed skills don't know what they're missing, and supervisors reviewing AI-assisted work cannot distinguish never-skilled from skilled performance. Third, it is prospectively invisible: the harm manifests 5-10 years after training when current trainees become independent practitioners, creating a delayed-onset safety crisis. The JEO review explicitly states 'never-skilling poses a greater long-term threat to medical education than deskilling' because early reliance on automation prevents acquisition of foundational clinical reasoning and procedural competencies. Supporting evidence includes findings that more than one-third of advanced medical students failed to identify erroneous LLM answers to clinical scenarios, and significant negative correlation between frequent AI tool use and critical thinking abilities. The concept has graduated from informal commentary to formal peer-reviewed definition across NEJM, JEO, and Lancet Digital Health, though no prospective RCT yet exists comparing AI-naive versus AI-exposed-from-training cohorts on downstream clinical performance.

Cytology lab consolidation demonstrates unrecoverability: 37 labs closed (45 to 8), 80-85% training volume eliminated. Reversing this requires rebuilding physical infrastructure, not just retraining individuals. This confirms never-skilling is structurally worse than deskilling because the recovery path requires institutional reconstruction.

Supporting Evidence

Oettl et al. explicitly acknowledge that never-skilling is a genuine threat if 'trainees never develop foundational competencies' and note that 'educators may lack expertise supervising AI use,' compounding the detection problem. This supports the claim that never-skilling is structurally harder to address than deskilling.

The threshold calibration skill deficit adds a detection-resistance mechanism: trainees may appear competent on the cases they see (AI-routed subset) but lack the judgment to determine which cases require attention in the first place. This meta-skill deficit only becomes visible when trainees must independently triage cases without AI routing.

Supporting Evidence

The review explicitly identifies upskilling inhibition (never-skilling) as detection-resistant because it lacks a pre-AI baseline to measure against — the skill was never acquired. The review also notes it is potentially unrecoverable because the training window closes, and calls for prospective studies measuring skill without AI after AI-assisted training periods to close this methodological gap.
