Laws of UX

Laws of UX, by designer Jon Yablonski, is a collection of psychology principles behind interface design, such as Fitts's law, Hick's law, Jakob's law, the Doherty threshold and the peak-end rule. Each law gets a one-line definition, its origins and practical takeaways, with a distinctive illustrated card for each, and the site is available in several languages and as a printed poster. Reach for it when a design review needs a named, citable principle behind a choice, from choice overload to the aesthetic-usability effect.
