Argumentation
Two broad divisions characterize orientations to studies of argumentation by communication scholars and scholars in other disciplines. First, communication scholars perform descriptive and normative studies of argumentation, as well as studies that attempt to integrate these two perspectives. Descriptive studies typically employ qualitative and social-scientific research methods and may analyze argumentation both in laboratory and real-world settings. Normative studies typically employ humanistic research methods and frequently analyze argumentation in the public sphere. Second, scholars may view argumentation as more of an epistemological activity—one that generates knowledge or justifies belief—or as more of a practical activity that is designed to achieve a variety of outcomes such as persuasion, consideration of a proposal, or acceptance of a premise. Various basic questions are addressed by argumentation research: How should we define “argumentation”? How should we analyze it? How should we evaluate it?
