So how would you distinguish between the different causes and how much it is one cause or another? If for example, much of the problem is low hanging fruit then one would expect that the overall scientific productivity level would in some sense slow down over time. If most of it is the sort of systemic issues you are discussing what observations could we make to test the claim?
