MWITA-PKSO-2026-010 · Evidence A · P1
Packaging color had no uniform main effect; its effect on stated purchase depended on congruence with vice versus virtue positioning.
What this does not establish
Image-based one-item purchase intention is not observed choice, purchase or consumption; only orange/green cues and stylized vice/virtue foods in Chinese samples were tested.
Counterevidence & uncertainty
The absence of a general color main effect rejects a context-free rule such as 'warm colors sell more'; product positioning determines direction.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and realized behavioral or commercial outcomes.
