Principlev1
When a newly designed context fails to change behavior
When a newly designed context fails to change behavior within one week, modify the cue visibility, friction points, or reward structure rather than concluding the behavior is impossible.
Why This Is a Principle
Derives from behavior being a function of person and environment (Behavior is a function of both the person and their), behavior occurring when motivation, ability, and prompt converge (Behavior occurs when three elements converge simultaneously:), and system structure determining outcomes (The behavior of a system arises from its structure, not from). The principle prescribes treating context design as iterative experimentation.
