When strangers get on a bus, they almost always spread out. Few people sit next to each other unless they really have to.
Partly that’s social norms. And partly it’s probability — and entropy is the name we give to it: the measure of how many possible configurations a system can take.
The social rules push people apart, but entropy makes the scattered state the most likely outcome.
You could put an extra conductor on the bus to tell people where to sit, filling rows neatly from the front. But that takes energy. Take the conductor away, and inevitably everyone spreads out again.
The lesson of the entropy bus is that order is costly, disorder is cheap — and dispersal from order to disorder creates a flow.
The art of regenerative design is to shape systems so that the most likely outcome, and the flow in that direction is also the most life-giving.
