This kind of scenario planning is a form of mental time travel we can do on our own. It works even better when we do it as part of a scenario-planning group, particularly one that is open-minded to dissent and diverse points of view. Diverse viewpoints allow for the identification of a wider variety of scenarios deeper into the tree, and for better estimates of their probability. In fact, if two people in the group are really far off on an estimate of the likelihood of an outcome, that is a great time to have them switch sides and argue the other’s position.
