MWITA-LOC-2026-002 · Evidence A · P1
Among Indian bilinguals, English versus Hindi ad language changed attitudes for multinational products in opposite directions by product type, while language was null for the local firm.
What this does not establish
These are immediate seven-point attitude/evaluation outcomes, not click, conversion, actual purchase, revenue or sales. The sample was educated urban bilingual students and the brands were fictitious; results cannot be transferred to monolingual, rural or lower-literacy audiences without testing.
Counterevidence & uncertainty
English was better for a multinational luxury product, Hindi was better for a multinational necessity, and neither generalized to the local firm; this directly rejects a simple native-language or English-is-premium rule.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral, commercial or welfare outcomes.
