Rationality and the Unexpected
Those who proceed rationally, rely on known factors. Otherwise they would have no basis for their calculations. Familiarity presupposes a past, as the future cannot be known! This is why rational approaches are based on the past and with it, they assume that time will remain sufficiently stable and that this is meaningful, because only if the future is like the past, rational procedure becomes possible.
If this is the case, they know the influencing factors, the cause and effect chains and the distractions which must be eliminated. Rationality, therefore, cannot incorporate the unexpected. It can react to surprises with a rethink, undertaken as quickly as possible, or by making attempts at control. But it doesn’t have a plan for the fact that the future is always different than one thinks. The best precaution is a plan B, however, this is also based on calculated variations of the future.
This is why people or teams who have a sense, who are intuitive, who cultivate an inkling, are in such demand in organisations. The terms used in the previous sentence are an indication that this is all about subtle perception competence and less about thinking.
