Disclosing fully automated generative-AI social content reduced post credibility, brand attitude and perceived authenticity; AI assistance produced a weaker penalty.
What this does not establish
Attitudes and loyalty intentions in US panels, not purchases; some stimuli used a fictional brand.
Counterevidence & uncertainty
Human-in-the-loop assistance attenuated the penalty, so this is not a universal AI-origin effect.
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.
