MWITA-SSCO-2026-011 · Evidence A · P1
Synthetic human presenters were not less effective than real presenters for identical business pitches on average; outcomes were stronger when audiences believed the presenter was human.
What this does not establish
Ratings are not leads, investment, sales, or long-term trust and results cover specific English business pitches.
Counterevidence & uncertainty
Objective production type showed a null average effect while subjective human attribution strongly separated ratings.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
