Don Norman and The Design of Everyday Things

Every time you push a door that should be pulled, or spend thirty seconds fighting a hotel faucet, you are living inside a design failure. Don Norman, the cognitive scientist who joined Apple in the 1990s and co-founded the Nielsen Norman Group, spent a career explaining why it is never your fault. His 1988 book handed the field a vocabulary it still uses, and one example became so common it earned its own name: a door that gives you the wrong signal, so you push when you should pull and feel vaguely stupid for it.

For anyone building a product, this is a case about the moment a user makes a mistake and quietly blames themselves. It sharpens a simple audit: when people get it wrong, was the cue clear, did anything tell them what to do, did the action confirm it worked? The framework Norman built to separate bad users from bad design, and how to run it against your own most common support ticket, is the part the app holds back.
