MWITA-AIAO-2026-011 · Evidence A · P1
Adding explanations or beneficiary framing to an AI disclosure did not repair advertising response in a preregistered replication; explanatory wording slightly worsened ad and brand attitudes while engagement intention was statistically equivalent.
What this does not establish
Fictitious-brand attitudes and stated engagement are not real campaign behavior; post-treatment noticing cannot be interpreted as randomized treatment.
Counterevidence & uncertainty
More explanation did not offset the disclosure penalty in realistic creative, despite a benefit in an earlier text-only study.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
