A Tale of Two Cultures: Contrasting Quantitative and Qualitative Research

Gary GoertzDepartment of Political Science, University of Arizona, Tucson, AZ 85721 e-mail: ggoertz{at}u.arizona.edu The quantitative and qualitative research traditions can bethought of as distinct cultures marked by different values,beliefs, and norms. In this essay, we adopt this metaphor towardthe end of contrasting these research traditions across 10 areas:(1) approaches to explanation, (2) conceptions of causation,(3) multivariate explanations, (4) equifinality, (5) scope andcausal generalization, (6) case selection, (7) weighting observations,(8) substantively important cases, (9) lack of fit, and (10)concepts and measurement. We suggest that an appreciation ofthe alternative assumptions and goals of the traditions canhelp scholars avoid misunderstandings and contribute to moreproductive "cross-cultural" communication in political science.
