Tóm tắt	Typological theory is a configurational approach to theory building in which the researcher specifies types — distinct combinations of the values of explanatory variables — and develops contingent generalizations about the outcomes associated with each combination. Codified by Alexander George and Andrew Bennett and refined by Colin Elman's explanatory typologies, it organizes cases into the cells of a property space defined by the interaction of variables, using case studies to populate and refine the types. It embraces causal complexity by treating combinations, not isolated variables, as the units of explanation.	The most similar systems design (MSSD) is a small-N comparative strategy that selects cases as alike as possible on many background characteristics but differing on the outcome of interest. By matching cases so that most potential confounders are held roughly constant, the design isolates the few factors that vary alongside the outcome as the candidate causes. Rooted in John Stuart Mill's method of difference and named by Przeworski and Teune, it is a cornerstone of comparative politics for drawing causal inferences from a handful of countries or cases.
