The Science Hierarchy

The science hierarchy (discussed here) actually has some empirical backing (seen via a comment on Overcoming Bias):

Controlling for observed differences between pure and applied disciplines, and between papers testing one or several hypotheses, the odds of reporting a positive result were around 5 times higher among papers in the disciplines of Psychology and Psychiatry and Economics and Business compared to Space Science, 2.3 times higher in the domain of social sciences compared to the physical sciences, and 3.4 times higher in studies applying behavioural and social methodologies on people compared to physical and chemical studies on non-biological material. In all comparisons, biological studies had intermediate values.

On the other hand, that empirical backing is low on the science hierarchy.

I wonder where climate research fits.
