Legibility

Making a complex reality readable to a central eye by simplifying it. That often destroys the illegible, local workings that made it function. "The deep failure… is the mistaken assumption that thriving, successful and functional realities must necessarily be legible" (Rao — A Big Little Idea Called Legibility, after James C. Scott).

The mechanism

1. You can't read a complex system.
2. You call your own incomprehension the system's "irrationality."
3. You impose a blank-slate order that's easy to read.
4. The system turns brittle and fails ("scientific" forestry, Brasília).

The motive is emotional: "legibility quells the anxieties evoked by apparent chaos." Alexander tells the same story structurally: planners turn semilattices into trees "because they cannot help it" (Tree vs Semilattice).

Not always wrong

Time zones and the metric system traded local fit for global coordination, and mostly paid off. What fails is imposing one view as "best for all" without acknowledging that it shifts both optima and power.

In this wiki

• The Agent-Maintained Wiki is itself a legibility engine. It makes sources readable to a central reader (the agent, the index). The guardrails against Scott's failure: flag contradictions instead of resolving them, keep seeds marked as hunches, and treat raw/ as the territory (T5).
• Process: heavy ceremony imposed for the manager's eye is legibility. This partly grounds Match Process Weight to Stage and Stakes.

Connections

• Legibility in the Lens, Not the Land — how the front door uses legibility without committing the failure.
• LATCH — Wurman's organizing is legibility for the reader, which is a different thing.
• Living Structure — the alternative: unfolding, not imposing.
