A. The distinction between combined and synthetic comparative strategies

The synthetic option: integrates several features of case-oriented and variable-oriented approaches. It does not completely synthesize variable-oriented and case-oriented methods; instead it selectively unites certain features of the two. In common with the variable-oriented strategy, it allows examination of large numbers of cases. In common with the case-oriented strategy, it allows assessment of complex patterns of multiple and conjunctural causation. This merger offers the possibility of a middle road between emphasizing relationships among variables and structural explanations, on the one hand, and emphasizing the chronological particularities of cases and human agency, on the other

The use of data and truth tables in comparative research is demonstrated here. Data tables provide a summary of all possible combinations of the variables involved as well as the actual combinations of causal conditions that differentiate sets of cases. Truth tables organize data in a way which allow simplification of causal configuration according to specific procedures that are demonstrated in the article.

C. Applications of Boolean Methods of Qualitative Comparison

Boolean methods of qualitative comparison have a variety of research applications. In what follows a brief example for the application of Boolean methods to macro-social inquiry is supplied.
