The contemporary scientific progress debate in philosophy of science and empirical evidence on _Knowledge That_ versus _Knowledge How_ in scientific practice

In his comprehensive survey of the contemporary debate over scientific progress in philosophy of science, Rowbottom observes that philosophers of science have mostly relied on interpretations of historical cases from the history of science and intuitions elicited by hypothetical cases as evidence for or against philosophical accounts of scientific progress. Only a few have tried to introduce empirical evidence into this debate, whereas most others have resisted the introduction of empirical evidence by claiming that doing so would reduce the debate to empirical studies of science. In this paper, I set out to show how empirical evidence can be introduced into the scientific progress debate. I conduct a corpus-based, quantitative study whose results suggest that there is a positive linear relationship between _knowledge that_ talk and _knowledge how_ talk in scientific articles. These results are contrary to Niiniluoto’s view according to which there is a clear distinction between scientific progress and technological progress such that _knowledge that_ belongs to the former, whereas _knowledge how_ belongs to the latter.
