Begin with choices most people expect, like local currency, common units, or the last used payment method, then politely show how to change them. In a transit app, auto‑selecting your saved stop feels magical only if the override is obvious. Start confident, explain gently, and always honor an easy path to adjust.
Let suggestions learn from behavior, but surface transparent cues like “Suggested based on your last three orders.” Offer a visible dismiss or “Don’t suggest this again” so agency stays intact. Adaptive help should feel like a friend offering options, not a pushy salesperson. Have you seen a helpful suggestion done right? Share the example.
When a preference is set, carry it forward across flows and devices, then provide a forgiving reset. A settings snapshot, undo toast, or review screen before confirmation preserves confidence. Users should never fear that experimenting locks them in. Which reset mechanism made you breathe easier recently? Let us know.
