A live workshop exercise: ask participants to draw a house in five seconds, then have a second person add to the drawing in another five seconds. Almost everyone draws the same conventional house (triangular roof, square base, door, windows) — demonstrating that people default to a shared, conventional mental model unless deliberately pushed off it.
Osterwalder uses it as a warm-up for innovation workshops to make a point that's otherwise abstract: teams asked to design a new product or business model will reflexively reach for the "default house" (the conventional format) unless something in the exercise design forces them elsewhere. Comparable in function to other workshop devices that expose default thinking, like the Black Mirror Episode Exercise and TRIZ (Worst-Case Design Exercise).
