A Label Said AI. The Evidence Map Said Whether to Believe It
An idealized provenance-density display separated true from fabricated passages by 4.15 rating points in an 81-person study.
Summary
An idealized provenance-density display separated true from fabricated passages by 4.15 rating points in an 81-person study.
Instead of a binary authorship badge, Provenance Density visualizes how much verified support sits behind a passage. Participants shown the idealized interface produced a large truth-versus-fabrication discernment gap, while the no-signal group showed no detectable separation. A 200-sample technical audit also found that retrieval density alone was insufficient; a consistency veto supplied most of the discriminative signal on dynamic questions. The authors argue for evidence visualization over authorship labeling, but the user study tested a designed interface rather than a deployed fact-checking system.
