>In user interface design and software design, the principle of least astonishment (POLA), also known as principle of least surprise, proposes that a component of a system should behave in a way that most users will expect it to behave, and therefore not astonish or surprise users. The following is a corollary of the principle: "If a necessary feature has a high astonishment factor, it may be necessary to redesign the feature." ("Principle of least astonishment", 2025).
