Abstract. This article describes the process of the aggregation of individual ministerial preferences into group decisions in a national cabinet, on the basis of a sample of crucial Dutch foreign policy decisions as described in the minutes of the council of ministers. The results of the study show that decisions in the cabinet were mainly made according to the norms of this group, which were consensus and the non‐interference of ministers in issues not concerning their department. Consensus turned out to be of secondary importance as compared with noninterference; key ministers could push through decisions by majority rule if they had consensus among themselves. Since specialists mostly made the decisions, the task of non‐specialist ministers was mainly to function as approvers or disapprovers, though they did make some minor contributions in cases of disagreement among the specialists. When there was agreement among the specialists they followed a process resembling the analytic model, i. e. one based on consideration of the consequences. However, when there was disagreement between specialists, they engaged in a cybernetic decision process, reviewing sequentially a large number of options, neglecting the consequences and striving for a consensus option such as incremental action, which would frequently be the result of a compromise.
