What is Donella Meadows systems thinking?

Donella Meadows systems thinking is a concept in personal epistemology: Real situations often involve several interacting feedback loops simultaneously.

Example: You decide to exercise more. The reinforcing loop is straightforward: exercise improves energy, which improves motivation, which makes you exercise more. But a balancing loop runs alongside it: exercise consumes time, which creates schedule pressure, which reduces available recovery, which produces fatigue, which reduces motivation. A third loop enters when you tell people about your new habit: social accountability reinforces commitment, but social comparison introduces anxiety about performance, which can undermine intrinsic motivation. No single loop explains your behavior. The interaction of all three determines whether the habit sticks or collapses. You cannot understand the outcome by analyzing any one loop in isolation — you have to see how they connect, conflict, and modulate each other.

This concept is part of Phase 24 (Feedback Loops) in the How to Think curriculum, which builds the epistemic infrastructure for feedback loops.
