Stepping stones in possibility space An Article by Gordon Brander subconscious.substack.com If we try to cross this lake by following only the stepping stones that lead toward our objective, we’ll soon get stuck. But what if we let go of our objectives? What if we focused on trying to find new stepping stones instead? This is novelty search. Instead of looking for something specific, you look for something new. Novelty search isn’t just random, it’s chance plus memory. Together, these ingredients do something interesting. ...Stepping stones are also combinatorial. Each new stepping stone we discover expands our potential to find even more stepping stones. Collecting stepping stones is a luck maximization algorithm. By collecting and combining stepping stones, we might arrive at our destination by accident, or somewhere more interesting! chanceknowledgeprogressnoveltyevolutioninvention
Two kinds of usability An Article by Ryan Singer world.hey.com I divide usability problems into two kinds: Perceptual: "They couldn't figure out what to do next", "they couldn't find the feature", "they didn't know they could click that button..." etc. Domain-specific: "We need a way to jump back here because in their workflow this happens..." In general, usability testing only catches type 1 perceptual problems. Because in those tests you take people out of the real world and assign them tasks. Usability testing doesn't catch domain-specific problems because they only come up in real life use. uxethnography
