MWITA-PKSO-2026-006 · Evidence A · P1
Heavier but visually identical packaging increased perceived flavor intensity and indirectly raised desire and willingness to pay through flavor evaluation, without a significant direct improvement in overall flavor evaluation.
What this does not establish
Small student samples, artificial added lead weights, single chocolates and soda, stated WTP and mediation models do not establish market sales or justify added material and logistics impacts.
Counterevidence & uncertainty
Packaging weight shifted intensity but not overall flavor evaluation directly; commercial value appeared only through a modeled serial pathway.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and realized behavioral or commercial outcomes.
