MWITA-PRO-2026-004 · Evidence A · P1
Larger preregistered replications found no robust purchase-likelihood advantage for multipack prices divisible by unit count.
What this does not establish
Hypothetical multipack purchase intentions are not observed sales, revenue or willingness to pay in a live store.
Counterevidence & uncertainty
The manipulation strongly changed perceived price divisibility but did not change purchase likelihood, contradicting the originally reported behavioral mechanism.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
