MWITA-BAO-2026-010 · Evidence A · P1
Extension exposure sped correct parent-brand categorization and improved parent recall, especially for nondominant brands, but both recall and recognition improved less than after equally repeated parent-brand advertising.
What this does not establish
Laboratory memory and response-speed outcomes for historical FMCG stimuli; not evidence of favorable attitude, product choice, sales, cannibalization or market value.
Counterevidence & uncertainty
Extensions helped parent memory relative to no comparable exposure but underperformed direct parent-brand advertising; cross-category exposure is not a free substitute for core-brand media.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
