Imagine you want to buy a new bike. Before you even walk into the shop, you already have a picture in your head. Where will you ride? City commute, gravel paths, weekend tours in the mountains? Luggage and how much? How often? You build a little mental model of your situation. And then, almost without noticing it, you walk into the shop and use that model as a lens.
