The 2025 Nature meta-analysis of 38 studies found **no overall memory advantage** for unfinished tasks. Same vendor-folklore-discipline pattern as [[60-70pct-dashboards-untraceable-vendor-folklore]] and [[cmi-2x-interactive-content-misattribution]].\n\n**How to apply:**\n- Strike \"Zeigarnik\" from Candid copy. Replace with goal-gradient / completion-drive language.\n- When a client invokes Zeigarnik, briefly note the 2025 meta-analysis result and pivot.\n- Save-and-resume features should be justified by Ovsiankina (resumption), not Zeigarnik (memory).","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"kivetz-2006-goal-gradient-coffee-stamps","title":"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","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"zeigarnik-2025-meta-no-memory-advantage","title":"CORRECTION: 2025 meta-analysis (Nature, Humanities & Social Sciences Communications; 38 Zeigarnik studies) — NO overall memory advantage for unfinished tasks (Cohen's dz ≈ 0.15)","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"ovsiankina-task-resumption-defensible-cousin","title":"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","kind":"reference","scope":"business","link_type":"depends-on"}],"incoming":[{"slug":"research-brief-interactive-tool-mechanisms-smb-june-2026","title":"Research brief: why interactive tools deepen a business's relationship with its audience — a mechanism-level research package (June 2026)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"article-the-number-does-the-talking-why-tool-beats-brochure","title":"Article (draft): The number does the talking — why a working tool beats a brochure every time","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"rule-engineer-clear-goal-and-immediate-feedback-not-deep-flow","title":"R2 — Engineer the robust flow components (clear-goal + immediate-feedback); do NOT promise \"deep flow\" for short tool sessions; the challenge-skill balance is shaky and contested","kind":"rule","scope":"business","link_type":"relates-to"},{"slug":"rule-cite-shen-fishbach-hsee-not-skinner-for-benign-uncertainty","title":"R6 — When variable/uncertain feedback is appropriate, cite Shen-Fishbach-Hsee (benign motivating-uncertainty, process focus, immediate resolution) — NOT Skinner box; respect the dark-pattern caveat","kind":"rule","scope":"business","link_type":"relates-to"}]},"created_at":"2026-06-20T18:18:57.615Z","updated_at":"2026-06-20T18:18:57.615Z"}
