4. Paper 7: A transition to language faculty science
　　The period between Paper 7 and Hoji 2015 is a slow process of my realizing:

(3)a.If we want to pursue rigorous testability, we should be engaged in a study of the language faculty rather than language or languages.
b.In language faculty science, so-called linguistic phenomena are not the object of our investigation; rather, they are probes in our investigation of the properties of the language faculty.
c.Being concerned with the language faculty as our object of inquiry, we must be an internalist.
d.Being an internalist, we should be concerned with making and testing predictions about individuals.

　　Paper 7 summarizes the empirical findings in Papers 1-6, focusing on BVA (and to a somewhat lesser degree on DR), but not addressing the sloppy-identity reading. The paper focuses on various correlations of informant judgments regarding the availability of BVA(A, B) and DR(A, B), drawing in part from works by A. Ueyama and J.-R. Hayashishita; see footnote 2. The paper also addresses local disjointness effects. It points out that local disjointness effects with BVA are not as robust as what is suggested in Paper 2, even with the kind of BVA that seems to have to be based on FD, and suggests a means to attain a more robust experimental result.
