Additive quantitative measures translate back into family resemblance concepts.

Evidence

If we make some assumptions about how quantitative measures reflect concept structures, notably that additive measures translate back into family resemblance concepts, then we can easily discover examples of the use of OR at both levels. We can take Schmitter’s three-level concept of corporatism as an example of how the basic family resemblance structure can be used at both levels. Figure 2.3 interprets how Schmitter has structured his corporatism concept (see the next section for a discussion of the various arrows and symbols). — Gary Goertz, Social Science Concepts, 336

• DEFINE: ‘Family resemblance’ here means OR-connected concept structure rather than the classical AND-defined kind. Useful for keeping straight how measurement assumptions map onto concept structure.
