Weak Ties (Granovetter's Strength of Weak Ties)

Granovetter's counterintuitive finding that acquaintances (weak ties) are more valuable than close friends (strong ties) for accessing new information, job opportunities, and novel ideas. Strong ties connect you to people who know what you know; weak ties bridge to distant networks with different information. Your close friends share your world; your acquaintances connect you to worlds you'd never otherwise access. This is why networking breadth often matters more than depth for opportunity discovery.

When to use it

When seeking new opportunities, ideas, or information; when your existing network keeps circulating the same perspectives; when building a network strategy—invest in breadth as well as depth; when innovation has stalled and the team needs outside perspectives.

How it can help

Deliberately cultivate and maintain weak ties—casual contacts across different industries, communities, and domains. The most transformative information, opportunities, and ideas typically come not from your inner circle but from your outer network. Practical strategies: attend events outside your industry, maintain light-touch connections with a broad network, and don't let acquaintance relationships atrophy. A quarterly coffee with 20 weak ties is often more strategically valuable than daily contact with 5 close allies.
