ABSTRACT
Planners inhabit bubbles. The bubble provides a womblike sense of comfort and security, an uncertainty-controlled environment in which the planner can work, using the repertory of procedures on the list of problems contained within the bubble’s walls. The planner may peer out to glance at the outside world; it is seen, however, only from the perspective afforded by the individual’s particular bubble. Because the bubble has invisible walls, the planner is not even aware of being in a bubble.
