Z., & Cross, R. (2004). \"The Strength of Weak Ties You Can Trust: The Mediating Role of Trust in Effective Knowledge Transfer.\" *Management Science* 50(11), 1477–1490.\n\n**Confidence:** Verified.\n\n**For Candid — the non-obvious operational claim:** It is not necessarily the *closest* tie that produces the best referral, but **the closest tie that also carries domain-competent trust**. A GC's brother who doesn't understand websites can be a worse referrer than a peer-coaching cohort member who does, even though the brother is closer. Strong ties without competence trust = high benevolence + low information value; weak ties with competence trust + brokerage position = optimal for novel-opportunity introductions.\n\n**Related:** [[mayer-davis-schoorman-1995-trust-ability-benevolence-integrity]] (Brief #2) gives the trust-dimensions framework Levin-Cross applied here.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"research-brief-trust-networks-in-group-reputation-may-2026","title":"Research brief: trust, referral networks, and in-group reputation in Ontario's trades economy (May 2026 — Foundation Brief #3)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"granovetter-1973-strength-of-weak-ties","title":"Granovetter 1973 (AJS) — strength of weak ties; surveyed Newton MA men found jobs more through acquaintances than close friends","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"marsden-campbell-1984-closeness-best-tie-strength","title":"Marsden & Campbell 1984 (Social Forces) — closeness is the best tie-strength indicator, NOT frequency or duration","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"mayer-davis-schoorman-1995-trust-ability-benevolence-integrity","title":"Mayer, Davis, Schoorman 1995 (AMR) — trust = ability + benevolence + integrity; all three required; absence of any forecloses trust","kind":"reference","scope":"business","link_type":"depends-on"}],"incoming":[{"slug":"warm-intro-hierarchy-eight-levels-ontario-trades","title":"Warm-intro hierarchy — 8 levels from cold inbound to family-equivalent referral; closest tie ≠ best referrer unless it carries domain-competent trust","kind":"reference","scope":"business","link_type":"depends-on"}]},"created_at":"2026-05-25T13:34:11.118Z","updated_at":"2026-05-25T13:34:11.118Z"}
