While findability comes first, we must also remember that categories are about more than retrieval. Classification helps our users to understand.
Through splitting, lumping and labeling, we reveal choices and invite questions.
Of course, all taxonomies are imperfect, as is the language they’re built on… like maps and myths, taxonomies hide more than they reveal. They bury complexity to tell a story, and they always miss someone out. Some things, like luggage, get lost by accident, while others – people, places, ideas – are buried by design.
Either way, each glitch in the matrix subtly changes understanding and behaviour, which is why this work has moral weight. Classification has consequences, as Geoffrey Bowker and Susan Leigh Star argue in Sorting Things Out:
“Each category valorizes some point of view and silences another. This is not inherently a bad thing – indeed, it is inescapable. But it is an ethical choice, and as such it is dangerous – not bad, but dangerous.”Peter Morville – Intertwingled (Amazon link here)
