MWITA-MR-2026-012 · Evidence A · P1
A 2025 PNAS study demonstrates autonomous LLM respondents can complete diverse surveys coherently and defeat simple identity/attention checks across 43,800 evaluations. Synthetic data may therefore contaminate the human benchmark used to validate synthetic research.
Counterevidence & uncertainty
Study automation may not bypass every panel's layered fraud controls; vendors can adapt detection and provenance.
What would change the reading
Panel audits quantify model-agent contamination and demonstrate robust multi-layer detection with low human exclusion.
