The cumulative dissertation analyses the use of evaluation results in direct-democratic campaigns on health policies and is supervised by Prof. Dr. Fritz Sager. The research is part of the SynEval-project „Policy Evaluation in the Swiss Political System – Roots and Fruits“ funded by the Swiss National Science Foundation in which the universities of Lucerne, Geneva, Lausanne, Zurich and Berne want to show how policy evaluations in Switzerland interact with the political system.
Switzerland has the highest amount of popular votes in Europe and is said to be a role model for direct democracy. Before the issue of a referendum or an initiative is put up to a popular vote, political actors form ad hoc coalitions for or against the issue and engage in a direct-democratic campaign. Campaigns aim at mobilising and persuading voters for or against the issue. To this effect, political actors frame their arguments, that is they select some aspects of the issue that allows them to promote a particular interpretation and evaluation of the problem. Naturally, we would expect that political actors include evidence to persuade voters of their position.
Research on direct-democratic campaigns in the last decade has concentrated on opinion formation, the role of the media as well as on the strategies of the political actors. There research on the use of evaluation results in persuasion is sparse and it is restricted to the effects of the frames on the recipients. Existing research on evidence-based policy making in Switzerland mainly investigates the use of evaluation results in the administration and parliament. There is no research analyzing the use of evaluation results when the decision on a policy measure is taken by a plebiscite. This PhD project aims at reconciling these two secluded research traditions by showing in which campaigns and in which form evaluation results are used, to what extent frames in direct-democratic campaigns are based on evidence and to what extent evaluation results are used in the opinion formation process.
