In Collier and Adcock’s Democracy and Dichotomies: A Pragmatic Approach to Choices about Concepts, they present a pragmatic peace offering to the longstanding disagreement regarding whether a dichotomous or a gradated approach to the distinction between democracy and nondemocracy is more appropriate.
In doing so, they do not advocate one approach in favor of another, but, instead, suggest that the choice between the two should be made on a context-specific basis, depending on the concepts being operationalized in any given measure of democracy. They do so by examining the conceptual justifications motivating various scholarly proponents of the two opposing approaches at different levels of generality; the general methodological defense, followed by generic justifications, and concluded by context-specific justifications. Collier and Adcock find the last to be the most convincing; in research that focuses on democratizations as a well-bounded event, as well as on classical subtypes of democracy, they see dichotomous approaches as being preferential; however, they acknowledge that alternative methods of evaluating democratizations and subtypes call for gradated measurements. Other contextual considerations, such as normative concerns and the empirical distribution of cases, also contribute to the decision between dichotomies and gradations.
Frankly speaking, what Collier and Adcock propose in dealing with the dichotomous/ gradated debate seems self-evident and quite simplistic. Clearly, each approach has its merits depending on what best serves the purposes of the researcher. I do, however, appreciate their discussion of the importance of sharper differentiation points; wherein gradations are combined with named categories. This approach is the one I would personally advocate in classifying regime types; prior to a certain point, no matter how much more ‘democratic’ a country is than a less ‘democratic’ country, it should not be considered as such until a certain bare minimum number of requirements is fulfilled.
