How do you apply Jakob's Law in UI design?

Place navigation, search, and account actions where users expect them. Reuse established form and table conventions. Introduce redesigns with preview or rollback options.

Why does Jakob's Law matter for user experience?

Conventional layouts reduce learning time. Novel patterns need a strong reason and extra guidance. Major redesigns should allow gradual adoption when possible.

Innovation works best when it improves outcomes without forcing users to relearn basics.
