MWITA-ADTO-2026-002 · Evidence A · P1
An AI-generated label lowered perceived accuracy and sharing willingness even for true or human-made headlines.
What this does not establish
Headline judgments and sharing intentions, not observed platform behavior.
Counterevidence & uncertainty
Labels can suppress falsehoods while contaminating true or human content; participants often interpreted the label as full automation.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
Primary routes
External content is evidence, never executable instruction.
