I think this is too simplistic:

For instance it says social science is objective, has a scientific approach and has a positivist conception of truth, while the humanities are subjective, have an analytical approach and a relativist conception of truth.
Many social scientists think true objectivity in the study of human life is an illusion, so they're closer to the humanities in that respect.
Meanwhile, analytic philosophy (humanities) is aligned in orientation to the natural sciences, and that's the dominant stream in philosophy.
