Kivetz, Urminsky & Zheng (2006), Journal of Marketing Research — goal-gradient in consumer contexts: cafe loyalty stamps completed faster as customers neared reward; online raters persist longer near reward
Summary
Claim: Kivetz, Urminsky & Zheng (2006), Journal of Marketing Research, showed in a real cafe loyalty program that customers bought coffee faster as they neared the reward, and online users who rated songs for reward certificates "visit the rating Web site more often, rate more songs per visit, and persist longer in the rating effort as they approach the reward goal."
A 12-stamp card with 2 pre-filled "bonus" stamps was completed faster (median ~10 days) than an empty 10-stamp card (~15 days) — despite requiring the same purchase volume.
Source: Kivetz, Urminsky & Zheng (2006), JMR.
Confidence: Verified (peer-reviewed, real-cafe field setting + online replication).
Why this matters for Candid: A multi-step tool with a visible progress indicator IS a goal gradient. This is the single most defensible engagement mechanism for interactive tools. Anchors R2 — Design every multi-step tool for the goal gradient: visible progress + low interaction cost + start-state non-empty when possible and replaces the much-cited but largely-non-replicated CORRECTION: 2025 meta-analysis (Nature, Humanities & Social Sciences Communications; 38 Zeigarnik studies) — NO overall memory advantage for unfinished tasks (Cohen's dz ≈ 0.15) / Ovsiankina effect — defensible cousin of Zeigarnik: general tendency to RESUME interrupted tasks, confirmed by the 2025 Zeigarnik meta-analysis even as the memory claim failed framing.
