How Systems Behave

Intermediate 12 notes ~1 hour

Most of the messes we live inside — traffic, bureaucracies, ecosystems, markets, our own habits — aren’t messes because someone was stupid. They’re messes because systems don’t behave the way intuition expects. Outputs loop back as inputs. Wholes do things their parts can’t. Small changes get amplified; sensible interventions backfire.

This path builds the vocabulary for that strangeness, then turns to its pathologies: the cobra effects and Goodhart traps where trying to fix a system makes it worse, and the commons problems where everyone acting reasonably produces a result nobody wants.

It ends with Donella Meadows, who spent a career asking the practical question underneath all of it — where, in a system you can’t fully control, can you actually push?
