Decision time grows logarithmically with the number of equally likely choices, so the tenth option costs far less than the second.

Time to hit a target depends on how far away it is and how big it is, which makes size and distance the two levers you control.
LAW·002Law · Motor control
People spend most of their time on other products, so they expect yours to work the way those do.
LAW·003Law · Conventions
Items at the start and end of a list are remembered best, which makes the middle of any list the weakest position.
LAW·008Law · Memory
Moving a pointer along a constrained path takes time proportional to the path length divided by its width, which is why nested menus are hard.
LAW·016Law · Motor control
Elements arranged along a line or curve are read as a connected sequence.
FND·008UI foundation · Gestalt principles
The structure that tells people what exists and where they are, which is an information architecture problem before it is a layout one.
PAT·001Pattern · Structure
Navigates to a destination, and must look different from surrounding text.
CMP·002Component · Actions
A panel that slides in from an edge, keeping context visible while offering more room than a popover.
CMP·011Component · Overlays
Parallel views in one space, which works only when users never need to compare across them.
CMP·016Component · Navigation
A list of actions revealed on demand, which is where infrequent operations belong.
CMP·018Component · Navigation
Content revealed below a trigger, a term that covers three different components and causes confusion.
CMP·019Component · Navigation
A trail showing where you are in a hierarchy, useful when the hierarchy is deeper than two levels.
CMP·020Component · Navigation
Splitting results into pages, which preserves position and keeps the footer reachable.
CMP·021Component · Navigation
The conventions phones have settled on, what each one is actually for, and where they break.
PAT·027Pattern · Structure
Shows where the reader is in a sequence, how much is left, and whether they can move between steps.
CMP·029Component · Navigation
Asking users to group content, which reveals their mental model of a domain rather than your org chart.
RES·005Research method · Information architecture
Testing whether people can find things in a structure, with no visual design to confound the result.
RES·006Research method · Information architecture
Measuring where people click first, which predicts task success better than almost any other single measure.
RES·007Research method · Evaluative
Organising, labelling and structuring content so people can find it, which determines navigation rather than following from it.
RES·015Research method · Information architecture
A review pass for anything that lives at a URL: addressability, navigation, performance, content and the browser behaviours people expect.
