Map your network clusters
Draw out the distinct social worlds you move in to find where your bridges are thin.
Key takeaways
- What it is: Draw out the distinct social worlds you move in to find where your bridges are thin.
- Why it works: Network theory shows that information and opportunity flow through bridges between clusters, not within them. Visualizing your clusters reveals which of your acquaintances sit at those bridging positions — and shows where you have no bridge at all, pointing to the gaps worth filling.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Treating the map as a one-time exercise rather than updating it as your circumstances change — networks shift constantly.
Why it works
Network theory shows that information and opportunity flow through bridges between clusters, not within them. Visualizing your clusters reveals which of your acquaintances sit at those bridging positions — and shows where you have no bridge at all, pointing to the gaps worth filling.
How to do it
- 1List five to eight distinct groups in your life (colleagues, former classmates, neighbours, hobby groups).
- 2For each group, name two or three people who connect you to that cluster but aren’t part of your inner circle.
- 3Identify which clusters have no crossover — those are your structural holes.
- 4Choose one structural hole to address in the next month by cultivating a tie in that cluster.
What the evidence says
ObservationalGranovetter’s original study found that job-finders who used personal contacts mainly relied on acquaintances rather than close friends. Later structural-holes research (Burt) reinforced that network bridges correlate with better job performance and faster promotion.
Honest caveat: Both studies are observational; causation is plausible but hard to isolate from selection effects (high-performers may also build more diverse networks).

Common mistake
Treating the map as a one-time exercise rather than updating it as your circumstances change — networks shift constantly.
