This is a really powerful concept; I can immediately think of at least two fields this applies to:
When you’re not sure how to build a software user interface, you might think “let’s run an A/B test on 1000 people and see which performs better”. But you’ll get 90 percent of the value just by showing it to one or two users and watching them use it, live.
When you’re learning to cook, one of the first things they teach you is to sample your food throughout. The first sip or bite will immediately tell you how to adjust the recipe (eg add more salt, add something spicy, or a dash of vinegar)
