It is normally implicitly understood that people at more senior managerial or executive levels have to operate at (and be comfortable with) progressively higher levels of uncertainty. Often, one has to make choices being cognizant of a superposition of multiple future states that is yet to be resolved into one or the other (not unlike a quantum one).
It is also true that key role of management is to enable people to be as productive as possible. Ergo, the manager’s job has to include a meaningful reduction in uncertainty that’s being passed through to the subordinates.
