Surveyed men more often found employment through acquaintances than through close friends.\n\n**Source:** Granovetter, M. S. (1973). \"The Strength of Weak Ties.\" *American Journal of Sociology* 78(6), 1360–1380. https://www.cs.cmu.edu/~jure/pub/papers/granovetter73ties.pdf\n\n**Confidence:** Verified (one of the most-cited papers in sociology).\n\n**For Candid:** Granovetter's original strong claim — weak ties as uniquely valuable — was walked back in [[granovetter-1983-weak-ties-revisited-walked-back]]. The applied lesson for trades is that **the contact at the supply counter or the HBA event whom you barely know** is more likely to introduce you to a new client than your closest professional ally — *for information about novel opportunities*. The closest ally is more likely to deliver the high-trust referral once an opportunity is identified.","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"}],"incoming":[{"slug":"granovetter-1983-weak-ties-revisited-walked-back","title":"Granovetter 1983 (Sociological Theory) — weak-ties claim walked back; strong ties carry relational guarantees weak ties cannot, esp. for trust under uncertainty","kind":"reference","scope":"business","link_type":"supersedes"},{"slug":"burt-structural-holes-1992-2004-broker-advantage","title":"Burt 1992 (Structural Holes) / 2004 (AJS) — brokers spanning holes between groups capture information-arbitrage advantage","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"levin-cross-2004-trust-mediates-tie-strength","title":"Levin & Cross 2004 (Mgmt Sci) — competence- and benevolence-based trust mediate tie-strength → useful knowledge transfer; once trust is controlled for, weak ties re-emerge as valuable","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-05-25T13:34:11.089Z","updated_at":"2026-05-25T13:34:11.452Z"}
