The Principle of Least Astonishment

The Principle of Least Astonishment suggests that when designing a system or interface, it should behave in a way that users naturally expect, minimizing surprises. Essentially, it aims to make interactions intuitive so users aren’t confused or shocked by unexpected results. By aligning with common habits and expectations, it enhances usability and reduces errors, allowing users to operate the system smoothly without needing to relearn or guess how it will behave. This principle helps create interfaces and systems that feel logical and familiar, improving overall user experience.
