Abstract
As generative AI makes polished prose cheap to produce, users can no longer rely on fluency as a proxy for truth. We call this failure mode the Fluency Trap: users trust fluent hallucinations while also discounting accurate content once it is disclosed as AI-generated. Binary 'Made with AI' labels respond with authorship disclosure, but they do not show what supports a claim. We propose Provenance Density, an evidence-visualization interface that shows the density of verified claims in a text. In a user study with 81 participants, an idealized Provenance Density interface produced a large discernment gap between truth and fabrication (+4.15 points, d=1.82), whereas participants given no signal showed no detectable discrimination. A technical audit with 200 samples shows that retrieval density alone is insufficient; unexpectedly, a Consistency Veto carries most of the discernment signal on dynamic queries. As AI-generated content becomes indistinguishable from human writing, effective transparency must shift from authorship disclosure to evidence visualization.
Key Findings
- The Fluency Trap: Users trust fluent hallucinations, while accurate AI-generated content gets discounted once its authorship is disclosed — fluency and labels both fail as truth signals.
- Provenance Density interface: Instead of binary 'Made with AI' labels, the proposed UI visualizes the density of verified claims in a text.
- User study (n=81): The idealized interface created a large discernment gap between truth and fabrication (+4.15 points, d=1.82); participants with no signal showed no detectable discrimination.
- Technical audit (200 samples): Retrieval density alone is insufficient; a Consistency Veto mechanism surprisingly carried most of the discernment signal on dynamic queries.
- Implication: Effective transparency should move from authorship disclosure toward evidence visualization.
