Information displays should be annotated, combining words, images, graphics, whatever it takes to describe and explain something. Annotation calls out and explains information and, at the same time, explains to viewers how to read data displays. Good annotation is like a knowledgeable expert/teacher at the viewer's side pointing and saying, "Now see how this works with that, how this might explain that..."
Yehudi Menuhin, a great violinist, marked up a score for Bach's Sonata No. 2 for Solo Violin. Penciled annotations show real-time performance strategies. To outsiders, insider markups appear chaotic and cryptic, but these personal annotations are for Menuhin's eyes, the only eyes that matter. All can learn from this useful workaday grid strategy: a relevant and intense data layer can become a coherent substrate scaffold upon which to overlay additional information. Maps do this all day long.
That’s the primary difference between an axiom like “Curiosity Killed The Cat” and an axiom like “You Are Not Your User. ” The former rings true in common experience. It’s test-able, like striking a tuning fork or dangling a bit of yarn in front of a kitten. The latter is just some stuff that somebody said.
Sometimes, axiomatic sayings like “You Are Not Your User” no longer have a who that’s saying them. They cease being an actual instruction, and instead serve as a kind of identity, to identify the person who’s repeating the axiom as One Of Us.
The technical term for when an axiom devolves into an ID card is shibboleth: a custom, principle, or belief distinguishing a particular class or group of people, especially a long-standing one regarded as outmoded or no longer important.
