Corona unveils a canvas to learn for the roles that planners need to explore, develop, and enact when facing global crises. Two counterintuitive claims help explaining. First, planning needs more uncertainty to take its roles. The more we know about the unfolding crisis, the harder any action becomes. This takes us to the heart of planning: values and societal goals. Second, planners should plan for uncertainty, both acknowledging and actively creating uncertainties. Reduction and production of different uncertainties are inevitably linked. Post-corona planning must even plan for uncertainty to succeed.
