This is another installment of my top 500 journal articles: the papers that I keep coming back to and recommending to others.<\/em><\/p>\n

Few papers have had a larger impact on my thinking and goals as Donella Meadows’s article Leverage Points: Places to Intervene in a System<\/a>:<\/p>\n

\nFolks who do systems analysis have a great belief in “leverage points.” These are places within a complex system (a corporation, an economy, a living body, a city, an ecosystem) where a small shift in one thing can produce big changes in everything.\n<\/p><\/blockquote>\n

She then explains how to understand them and where to find them, with fantastic examples from across the systems literature: global trade, ecology, urban planning, energy policy, and more. Reading it makes you feel like a kid in a candy shop, with so many leverage points to choose from. Shamelessly stealing<\/a> a punch-line graphic, here are the leverage points:<\/p>\n

\"leverage<\/p>\n

I have a small example of this, which you can try out. Go to my Thermostat Experiment<\/a> and try to stabilize the temperature at 4 °C without clicking the “Show Graph” button until at least 30 “game minutes”. Then read on.<\/p>\n

I’ve had people get very mad at me after playing this game. Some people find it impossible, get frustrated, and want to lash out. It’s a very simple system, but you are part of the system and you’re only allowed to use the weakest level of leverage point: the parameter behind the thermostat knob. What would each of the other leverage points look like?<\/p>\n
