State laws mandate AI disclaimers on political content. But new research suggests voters may read them differently than policymakers intended — and sometimes don’t see them at all. The AAPC Foundation presents findings from the first practitioner-led controlled study of its kind — research designed by the professionals who create and test political messages, using realistic ad stimuli reflecting actual campaign conditions. The study examines how disclaimer presence, size, and language shape voter trust and authenticity perceptions. The results offer new empirical evidence for campaigns, consultants, policymakers, and the public as they consider questions of AI transparency in political communications.
