 A key assumption of the foregoing argument is that there is a strong connection between the amount of scientific work (as measured by the number of journal articles) and the degree of success of the best scientific theories. But this can be contested on the grounds that it’s a lot easier to publish currently than it was in the seventeenth century and that current research is more tightly connected to the defense of a single theoretical paradigm than before. This might well be a sign of maturity of current science but, as it stands, it does not show that the present theoretical paradigm is not subject to radical change. Florian Müller (2015) put the point in terms of decreasing marginal revenues. The correlation between increased scientific work and scientific progress, which is assumed by Fahrbach may not be strong enough:
