This course introduces first year PhD students to qualitative methods in political science. It aims to provide students with the necessary toolkit to assess how the choice of research method impacts research results, and to critically analyze how arguments are laid out and justified. First, it begins with the basics of epistemology and the philosophy of social science. Second, it covers debates on issues such as theory testing and theory formation, case selection in non-statistical research, the comparative method and the identification of causal mechanisms. Third, it presents a series of techniques for data collection and analysis, including archival research, interviewing, ethnography, and discourse analysis.
