MWITA-MR-2026-008 · Evidence B · P1
A 2025 preprint reports randomized experiments across seven workflows and millions of users/products at a cross-border retailer, with effects ranging from zero to 16.3% and only four applications positive. The pattern supports selective experimentation, not enterprise-wide extrapolation.
Counterevidence & uncertainty
Anonymous platform, preprint status and limited replication details constrain transportability; null applications matter.
What would change the reading
Peer-reviewed replication across named retailers/languages or later corrections materially change effects and costs.
