MWITA-HCO-2026-011 · Evidence A · P1
Identical digital medical advice was judged less reliable and empathetic and elicited lower willingness to follow when labeled as AI-generated or human-plus-AI than when labeled human-generated.
What this does not establish
Source-label perception is not actual adherence, advice accuracy, clinician behavior, or health outcome; results do not justify concealing material AI involvement.
Counterevidence & uncertainty
Physician supervision labeling did not remove the anti-AI perception penalty even though advice content was held constant.
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.
