Description

Why do users expect your site to work like the others they use? Why do too many options slow decisions down? Laws of UX gathers the psychology principles behind questions like these into one short, illustrated book.

What you'll learn

Jon Yablonski, who also created the popular lawsofux.com website, explains one principle per chapter, among them Jakob's Law, Fitts's Law, Hick's Law, Miller's Law and the Peak-End Rule. Each chapter covers where the principle comes from, how it shows up in real products, and what it means for your design decisions.

The book also discusses the ethics of applying psychology to design, so these principles help users rather than manipulate them.

Who it's for

It suits designers and product people who want a quick, well-sourced reference to back up decisions in a team discussion. You need no background in psychology.

At under 200 pages it favours breadth over depth. For a fuller tour of the research, pair it with 100 Things Every Designer Needs to Know About People.
