How do I practice choice architecture?

The most direct way to practice choice architecture is through a focused exercise: Pick one behavior you've been trying to change through willpower alone. Map the current context: what cues trigger the unwanted behavior? What friction exists before the desired behavior? Now redesign one element — move an object, change a default, set a visual cue, or create an implementation intention ('When I finish lunch, I will walk for 10 minutes instead of checking my phone'). Run the new design for one week. Document what happens.

Common pitfall: Designing contexts once and never iterating. Your first context design is a hypothesis, not a solution. If the new arrangement doesn't change behavior within a week, the cues are wrong or the friction is in the wrong place. Context design is an ongoing practice, not a one-time setup.

This practice connects to Phase 9 (Context Sensitivity) — building it as a repeatable habit compounds over time.
