The aim of this research program is to develop theoretical and practical instruments for the analysis, evaluation and production of argumentative discourse in different communicative domains. The research builds on two important developments that have taken place within the pragma-dialectical approach to argumentation in the last fifteen years. The first development concerns the integration of rhetorical insights into the standard pragma-dialectical theory of argumentation by introducing the notion of ‘strategic maneuvering’: the balancing act that arguers perform in their attempt to be reasonable and effective at the same time. The second and most recent development is a further contextualization of the study of argumentation by focusing on specific conventionalized argumentative practices (or ‘activity types’) and by investigating which argumentative patterns may be regarded as prototypical for those practices. In dealing with the following seven research themes, the research program combines qualitative and quantitative research.
