Thinking In Systems: A Primer by Donella H. Meadows - the classic introduction to systems thinking. Meadows (the main author of The Limits to Growth) shows that system behavior is not caused by outside events but by the internal structure itself: the stocks, connections and feedback loops that define what a system can and cannot do. Forget blaming individual events - understand the structure. The final chapters map the famous leverage points: the places where a small, well-aimed nudge changes the whole system's behavior, and the traps (tragedy of the commons, rule beating) where good intentions make things worse. Frequently cited as a key influence by programmers and computer scientists - which is exactly why it belongs on this page.
