Traditional design mainly operates in the Probable cone, as it extrapolates on what is likely to happen and is conditioned by current trends and constraints.
The cone of Plausible futures designates what could happen through scientific discoveries or alternate social practices.

Intersecting a part of both plausible and probable futures, a Preferable area delineates where SD should be deployed in order to collectively define a preferable future.
