Show the data; don't just assert it

Tell someone "interest rates affect the payment a lot" and they nod and forget. Show them a loan with a slider on the rate, let them drag it, and watch the payment move in real time — now they understand it, because they saw it happen and made it happen themselves. The claim was abstract; the live thing is concrete. People learn the thing they can touch, not the sentence about it.

Bret Victor built a career on this point: make the state visible, give immediate feedback, and let the person manipulate the system directly instead of guessing what it does. When an explanation hides its data behind prose, the reader has to take it on faith. When it shows the data and lets them poke it, they can check it for themselves — which is also why A good explanation is hard to vary, since a visible model exposes exactly where it would break.

This is why interactivity, when we add it, has to earn its place. A slider that reveals how the numbers actually move teaches; a slider added for polish just decorates. The display is never neutral, because The interface shapes what you can think — what you let people see and touch decides what they can come to understand.
