This article argues that evidence, even when politically used, contributes to high-quality democratic discourse. Research results on the use of evidence in referendum campaigns in Switzerland show that 1) evidence fosters discourse quality and shifts the focus away from politics to policy; 2) primarily evaluations and basic research positively contribute to discourse, but not opinion surveys and statistics; 3) the participation of experts and administrative practitioners in discourse is crucial to make evidence available to the public; and 4) evidence is always used as a part of a narrative and can alter the constructed images used in a story. In conclusion, the implications for practitioners are discussed.
