The purpose of the ranking, in my opinion, is that it lends degrees of confidence to the conclusions drawn in different fields. Controlling for variables and repeatedly experimenting is crucial to science.
Many peer-reviewed, and generally 'accepted', psychological and sociological studies are neither experimental nor repeatable. Compare this to math, physics and chemistry where peer-reviewed and 'accepted' theories are always tested many times before being published.
When a 'science' strays from repeatable experiments, it also loses some credibility with me.
This. The more accurate in terms of predictive power a theory is, the better it is. Physics, Chemistry, and Biology all tend to have extremely high reliability as far as their theories are concerned, because it appears that the nature of the subjects they describe is highly consistent. It's not often you make new observations that break these previously well defined and observed patterns.
Sociology, on the other hand, is much, much less reliable because the subjects it studies are highly adaptable and individual. It's extremely difficult to come up with rules that govern behavior because there are just too many variables to control for, let alone the fact that each animal / person has its own free will, genetic inclinations, and life experiences that lead them to often make different decisions in the same scenarios. I wouldn't say that it's completely useless as a field of study, but it's so unreliable that I would have a hard time putting stock in anything it has to say. Studies are often hard to replicate, and even when they are repeatable, they don't apply to a significant portion of the population anyway.
To try and equate "hard sciences" with the "social sciences" is completely dishonest. There is (quite literally) a world of difference between them and their usefulness.
