MWITA-ICO-2026-003 · Evidence A · P1
In a real micro-influencer campaign, an explicit advertisement label produced more engagement per reach than no label, while randomized sentiment did not differ by disclosure.
What this does not establish
Only one real post per condition in fixed sequence creates time and platform-algorithm confounding; the field component was not simultaneously randomized.
Counterevidence & uncertainty
The engagement ranking favored explicit disclosure, but the randomized sentiment test was null rather than a general transparency benefit.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
