What is bottleneck analysis?

Bottleneck analysis is a concept in personal epistemology: When everything must flow through a single connection that connection is a critical vulnerability.

Example: In March 2021, the container ship Ever Given ran aground in the Suez Canal, blocking the 265-meter-wide waterway for six days. The canal normally handles roughly 12% of global trade. The blockage delayed 432 vessels carrying cargo valued at $92.7 billion, cost an estimated $400 million per hour in stalled commerce, and triggered supply chain disruptions that persisted for months. The fundamental problem was not the ship. It was that global shipping had funneled an enormous volume of trade through a single 193-kilometer channel with no bypass. The canal was a bottleneck relationship — a connection so central that its failure propagated instantly to every system that depended on it.

This concept is part of Phase 13 (Relationship Mapping) in the How to Think curriculum, which builds the epistemic infrastructure for relationship mapping.
