But complex systems are, well, complex. The purpose or function of the system 2.

This article is about leverage points related to System Dynamics. The conference is inspired by the seminal essay by Donella Meadows on Leverage Points: Even the simplest-seeming systems can turn out to be much more complex than first thought.

Interest rates, for example, or birth rates, control the mwadows around reinforcing feedback loops. You have to work hard at it, whether that means rigorously analyzing a system or rigorously casting off your own paradigms and throwing yourself into the humility of not-knowing. Any system, biological, economic, or social, that gets so encrusted that it cannot self-evolve, a system that systematically scorns experimentation and wipes out the raw material of innovation, is doomed poinfs the long term on this highly variable planet.
