The systems scientist who gave policymakers a hierarchy of leverage points—and showed why the interventions governments reach for first are almost always the least powerful ones available.

Where others saw events, she saw feedback loops; where others saw problems, she saw system traps; where others proposed solutions, she asked which rung of the leverage hierarchy the solution occupied and whether that rung was high enough to change anything lasting. Her 1972
Limits to Growth was the first computer model of global-scale planetary overshoot, and the backlash it provoked taught her that even technically correct analysis fails when its audience cannot see the system the analysis describes. She spent the rest of her career building the tools for that seeing:
