The reason I like Research through Design (beyond it sounding fancier than “prototyping”) is that it doesn't force me to build a better mousetrap every time. Sometimes the better mousetrap is the right answer, and I do enjoy that. But sometimes the right answer is a measurement system or a body of work, and sometimes it's an artifact whose only job is to make something legible. That way, the method is formed to fit the problem, not the other way around.
Underneath each instrument sits the same piece of scaffolding: a confidence matrix. Every claim gets a grade covering what's measured, what's inferred, and what's still a hunch, with the evidence attached to the grade. Aquadrio wears this on its sleeve, grading each hour against what the basin can afford instead of rounding everything up to “sustainable.” The others carry it more quietly because confidence should be earned in public.
And just between you and me: if I'm not creatively solving real problems, my brain tends to creatively invent them. I'd rather stay in the real world.
