The norm was first formally articulated by **Gouldner (1960)**.\n\n**Source:** Cialdini, *Influence: The Psychology of Persuasion*; Gouldner (1960), \"The Norm of Reciprocity,\" *American Sociological Review*.\n\n**Confidence:** Verified / Industry-consensus.\n\n**Caveat:** Reciprocity online is **low-cost** — the \"favour\" is ambient. A free tool likely produces **diffuse goodwill / brand warmth** more than a strong one-to-one obligation. Strongest when the free value is genuinely substantial (a real estimate the user would otherwise pay for); weakest when \"value\" is a thinly veiled lead-capture gate.\n\n**Why this matters for Candid:** Anchors the trust argument for ungated tools ([[rule-default-to-directional-range-ungated]] from Brief A). Tools that gate the result behind an email capture invert the mechanism — the user no longer perceives a gift, they perceive a transaction.","rationale_body":null,"metadata":null,"links":{"outgoing":[],"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":"berger-milkman-2012-practical-value-virality","title":"Berger & Milkman (2012), Journal of Marketing Research — practical usefulness independently predicts content virality even after controlling for emotion","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"rule-lead-mechanism-case-not-vendor-stats","title":"R1 — When recommending an interactive tool, LEAD on peer-reviewed mechanism evidence (goal-gradient, self-reference, IKEA, reciprocity, anchoring) — NOT vendor \"2× / 47% / 16.9×\" stats","kind":"rule","scope":"business","link_type":"depends-on"}]},"created_at":"2026-06-20T18:18:57.479Z","updated_at":"2026-06-20T18:18:57.479Z"}
