MWITA-LRO-2026-012 · Evidence A · P1
Without prior reviews, Airbnb requests from guests with African American-sounding names were accepted 19.2 percentage points less often; one credible peer review made Black–White acceptance rates statistically indistinguishable.
What this does not establish
Acceptance is an inquiry-to-booking gateway, not completed stay, host revenue, Maps ranking, review score, or evidence that fabricated testimonials are effective or permissible.
Counterevidence & uncertainty
Valence is not the only mechanism: even nonpositive or blank transaction-linked peer reviews reduce disparity, while equivalent self-description does not, highlighting source credibility rather than positivity alone.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
Primary routes
