MWITA-SPEO-2026-001 · Evidence A · P1
Prior exposure to a direct competitor sponsor reduced identification of the focal incumbent sponsor from 85.5% to 66.7% in Study 1; Study 2's pooled competitor main effect was null, with effects varying by sponsor tenure/context.
What this does not establish
Measures sponsor identification/recognition after event communications, not attitude, purchase, sales, profitability, or long-term brand equity.
Counterevidence & uncertainty
The large Study 1 interference effect does not reproduce as an unconditional main effect in Study 2; sponsor tenure and communication ecology bound transfer.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and realized behavioral or commercial outcomes.
