Reality Has a Surprising Amount of Detail — And Why That Traps Even Experts

John Salvatier argues that every real-world task hides far more meaningful complexity than it appears to from a distance. Using the example of building basement stairs — which sounds like screwing a few boards together but actually involves tracing angles, compensating for warped lumber, drilling guide holes so screws don’t skew brackets, and picking screws that won’t stab through the treads — he shows that each simple-looking step decomposes into subtasks with material consequences. This ‘surprising amount of detail’ isn’t specific to carpentry; it’s a near-universal feature of getting close to reality, from growing vegetables to wiring up a Haskell package.

The piece’s sharper point is about cognition. Beginners repeatedly mistake the inherent fiddliness of reality for personal incompetence, then later dismiss it as ‘simple all along’ once the details become habitual. Programmers feel this acutely only because they tackle new things often. Even physics, whose underlying laws are elegant, manifests messily — Salvatier’s extended example of boiling water (bubbles that seem ‘unboiling,’ glass vessels that raise the boiling point, and droplets superheated past 300°C) demolishes the tidy claim that water boils at 100°C.

The significance for anyone doing hard, unproven work: the harder the goal, the more of these hidden details turn out to be load-bearing, and you can’t assume they’re irrelevant. Details that seem incidental — like wood warping, which makes it better to trace a cut than calculate it — are exactly the ones that determine success or failure. Overlooking them is how smart people, even leaders in their fields, get intellectually stuck.
