The laws this book leans on — not a catalog; lawsofux.com is the catalog, and it's excellent, go there. These are the few that carry weight in these pages, each with where it bites: Fitts (distance and size → Two Steps Ahead, When Things Go Wrong) · Jakob (people arrive trained by every other product → Behavioral Consistency, and under every promise in the book) · Peak-End (an experience is remembered by its sharpest moment and its last → Silence Is a Message, When the Promise Breaks, Yearn). A law gets a line here only when a chapter actually uses it.

The rules, one line each, with the page they come from.
