MWITA-LOC-2026-006 · Evidence A · P1
The optimal degree of localization varied sharply with market openness: Belgium showed null differences, India favored glocalization, and Iran mostly favored full adaptation.
What this does not establish
Adaptation bundled celebrity, language, cities and domain, so it does not isolate translation alone. Outcomes are attitudes and purchase intention, not click, conversion, actual purchase, revenue, sales or retention; urban higher-SES samples and one durable category constrain transfer.
Counterevidence & uncertainty
Full adaptation was not best everywhere: Belgium was null, glocalization led in India, and Iran's adapted-versus-standardized advantage disappeared for brand attitude and purchase intention.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral, commercial or welfare outcomes.
