Principles
A system for turning repeated decisions into explicit principles, testing them against reality and improving them over time.
Why it matters
Codified rules can reduce inconsistency and make reasoning easier to inspect, challenge and transfer.

Core ideas
What is worth remembering after you close the page
01
Make reasoning explicit
Written principles expose assumptions that otherwise stay hidden in intuition.
02
Use mistakes as data
Painful outcomes are most valuable when traced back to a process that can be redesigned.
03
Match people and roles
Good systems account for differences in strengths rather than assuming everyone should operate the same way.
03
Turn it into action
Three things to test today
- 1
Write one recurring decision rule you currently use implicitly.
- 2
Test it against three past examples.
- 3
Change the rule if it predicts the wrong behavior more than once.
