https://en.wikipedia.org/wiki/Hard_and_soft_science
From the wikipedia article:
> [hard sciences have the characteristics of] testable predictions, performing controlled experiments, relying on quantifiable data and mathematical models, a high degree of accuracy and objectivity, higher levels of consensus, faster progression of the field, greater explanatory success, and generally applying a purer form of the scientific method.
It's actually a big problem with modern research in general.
