Mental Models

The beliefs people hold about how a product works, based on their experience.

Why it matters

When a design matches what people expect, it feels easy without being taught.

How to use it

  • Learn what users believe, through research.
  • Fit the design to those beliefs.
  • If you must break them, teach the change clearly.

Example

People expect a trash icon to mean an item can usually be recovered, like a real bin.
