What if the goal isn't to design a product—but to design the behaviour towards a product?

Feels like Facebook did this… they wanted people to be addicts so they designed the product to encourage the behavior based on psychology

I was thinking a bit more optimistic like how architecture can shape the meaning of objects within it—or 3D, changing the lighting within a scene affects the perception of the object. It's the same principle: you design the indirect relationships rather than the object itself.
