Laws of UX

Yablonski collects the psychological principles that keep turning up in interface decisions and explains each one with worked examples. Coverage includes Fitts's law and Hick's law on target size and choice, Jakob's law on the conventions people bring from other products, Miller's law on the limits of working memory, and the peak end rule on how an experience is remembered. Each principle is given its origin, what it means for design work, and the ways it gets misapplied. A closing section deals with the ethics of using psychology on people, which matters because these principles work whether or not the user benefits. Short, heavily illustrated and easy to reach for in a design review.
