How to utilise this in your designs

You could offer to import settings from a user's existing tool during setup, so the new product feels familiar, and remind them of the effort of starting from scratch.

Split UI with black left panel titled "Get us up to speed" and a blue "Next" button; right panel with radio buttons for Edge, Safari, or manual password entry choices.

Example from

Arc

Try anchoring each option on an abstract scale to a familiar sensation, e.g., whether you could still hold a conversation, so ratings are quicker to interpret.

Black UI panels show exercise intensity levels 1, 7, and 9 with white bold numbers and labels; underlined orange text emphasizes "walking slowly," "hard to talk," and "no talking."

Example from

Nike

You could change a CTA label when someone has used a template before, acknowledging their familiarity and reducing uncertainty about what clicking will do.

Quick Notes UI with a "Use template" button highlighted by an arrow and "Add again" button underlined; lists show tags Idea, Note, Reminder in color-coded labels.

Example from

Notion

When launching a new way to search, you could show clickable example queries inside a familiar feed, so users can try it without inventing an unfamiliar input.

Example from

Netflix

Possible impacts
