Yeah - I don't recall ever having heard the term "Paradigm Shift" before reading that book. The point of the study was that as scientific endeavors became more skilled, certain collections of assumptions (paradigms), couldn't explain or match experimental results, and when the whole premise was rethought, new questions could be asked, which wouldn't have even made sense to phrase or ask prior to that change. I was reminded of it taking a course called "Introduction to research in Music" when I went back to grad school a couple of years ago - it was actually cited in one of the readings, but the instructor had never pursued t.i I nudged her a couple of times - her husband is a scientist, and she said he hadn't read it either.
But why I mentioned it here in the forum was that in that context, at least, the term "Paradigm Shift" was completely meaningful and appropriate. There were later editions that doubled the number of examples and case studies, but I don't think the inclusion of more examples really made the thesis any more compelling to reasonably educated non-specialists.
