What is environment design for behavior change?

Environment design for behavior change is a concept in personal epistemology: Your environment can enforce behaviors that willpower alone cannot sustain.

Example: You decide to read more and scroll less. For three weeks, you rely on discipline — picking up the book instead of the phone. It works until a stressful Tuesday when the phone wins. Then you move the phone charger to the kitchen and place the book on your nightstand. Now reading is the default and scrolling requires getting out of bed. You didn't become more disciplined. You delegated the enforcement to your environment.

This concept is part of Phase 27 (Delegation Patterns) in the How to Think curriculum, which builds the epistemic infrastructure for delegation patterns.
