MWITA-SBO-2026-003 · Evidence A · P1
Untailored AI reduced pharmaceutical sales activity and units sold, whereas a human-centered implementation tailored to work styles increased customer meetings.
What this does not establish
No general productivity claim for AI; the setting is regulated Nordic pharmaceutical selling, the randomization has only 12 business units, and implementation occurred in 2014.
Counterevidence & uncertainty
The untailored implementation produced a material backfire, and the tailored positive sales-volume estimate remains statistically uncertain.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial or human outcomes.
