Don Norman

Don Norman is an American cognitive scientist and design researcher whose work on human-centered design transformed how the technology industry thinks about usability.

Don Norman’s career spans cognitive psychology, computer science, and design. He spent years at Apple as a Vice President of Advanced Technology, later co-founded the Nielsen Norman Group (the most influential user experience research consultancy in the world), and has taught at UC San Diego, Harvard, and Northwestern.

The Design of Everyday Things — first published in 1988 as The Psychology of Everyday Things and revised in 2013 — is his foundational contribution. The book introduced the vocabulary that the design and technology industries now use to discuss usability: affordances, signifiers, feedback loops, conceptual models. Its central argument — that user errors are almost always design failures rather than user failures — permanently shifted how designers approach their work.

Norman’s subsequent books — Emotional Design, The Design of Future Things, Living with Complexity — have extended the framework into emotional response, autonomous systems, and systems thinking. But The Design of Everyday Things remains the essential text: clear, rigorous, and impossible to finish without looking at the world differently.
