The article examines and confirms the hypothesis that political decision makers gather information and do not use it; ask for more information and ignore it; make decisions first and look for relevant information afterwards; and, collect and process a great deal of information that has little or no direct relevance to decisions. The results are based on interviews with members of the Norwegian national assembly’s Standing Committee on Transport and Communications. In three parliamentary periods, members were interviewed about their use of results from analytic planning models evaluating the projects and strategies of three consecutive road and transport plans. It is studied how the attitudes of the politicians towards the analytic results change as the planners supply increasingly advanced means-ends models.
