I am sorry you were not impressed AnCatDubh but these were abstracts and the only link I had. I would not characterize hypotheses as assertions or even agendas: it’s the way academic research works. You look at the data, you see patterns, you form a hypothesis that may explain what you are seeing, and then you do the research, gathering the evidence — hoping to prove your hypothesis but knowing you may find out you are wrong. Or you may end up going down an unexpected pathway and reformulating the original hypothesis. As far as the numbers are concerned, numbers are numbers. Professor Matthews went back and literally counted.
