I think most people are prone to make decisions based on intuition and past experience which has led many organizations to create decision making models to assist staff to move from away from intuition and more to set course of rational capacities, questions and answers and courses of action. This is not to say that we should avoid intuition and past experience. After action review notes from previous events can assist us to delve deeper into a decision making model, with knowledge of outcomes of previous actions. Using both rationality and intuition gives the broadest perspective.

If conflict occurs between the two one may prevail over the other, however, a suggested way to decide could be to run two separate courses of action; one based on each approach. Which approach brings the best result can be looked at and revised if needed. Using a hybrid of each approach though may bring a better result in place of rational vs intuition.

In past experience from small group organizations, military planning or disaster operations we overcame this by using hybrid of both which was usually successful. This is not to suggest that every operation or activity was successful but we used the best information processed through the best experiences to achieve a desired course of action.
