What is choice architecture vs willpower?

Choice architecture vs willpower is a concept in personal epistemology: Changing the environment is more effective than making rules about behavior within it.

Example: You tell yourself 'no phone in bed after 10 p.m.' and break the rule within three nights. Then you buy a cheap alarm clock and start charging your phone in the kitchen at 9 p.m. The phone never enters the bedroom again. The rule required nightly willpower. The architecture required one decision — where the charger lives — and physics handled the rest.

This concept is part of Phase 38 (Choice Architecture) in the How to Think curriculum, which builds the epistemic infrastructure for choice architecture.
