Abstract A sample of 235 Foreign Policy decisions from 1900 to 1955 was studied with respect to the structures of the argumentations. Although it is assumed in the literature that political decisions are complex value problems with uncertainty, the data did not show any evidence in support of this assumption. However, four groups of simplified structures of decision problems could be detected, based on restrictions specified for characterizing probabilities and/or values. Given these restrictions, it was found that more than two thirds of the decisions were in agreement with the SEU model as a normative criterion for correct decisions. But within the class of “correct” decisions the decision was always made in one and the same way. The decision makers indicated that the preferred strategy led at least to as good a result as the other strategies, but possibly to better results. In this argument probability played only a minor role. Trade offs between utilities and probabilities were not made.
