Design: Principle Of Least Astonishment
John Spacey, updated on January 13, 2023
The principle of least astonishment is a rule of thumb that states that user interfaces are best when they aren't surprising. That is to say, that when a user first sees your design they aren't surprised by how it works. This lowers the learning curve for users and tends to generate positive emotions. When users need to invest in learning a design, they may feel that they are bending to technology as opposed to technology bending to them.
