Laws of UX
Best practices for designers building user interfaces

Laws of UX is a curated reference collection of psychological principles, cognitive biases, and design laws relevant to user interface design. Each entry explains a concept—such as Fitts's Law, Hick's Law, or the Peak-End Rule—with a concise definition to help designers make informed decisions. It serves as a free educational resource for UX practitioners and product designers.
The site presents a curated list of named UX laws and principles, each with a brief explanation of the concept and its design implications.
