But humanists do have great skill in re-framing what is being said, shining light on cultural and historical influences and biases, and revealing theoretical lenses that may be coloring {the news, the science, the story, the commentary, the solution, etc.}. Scientists and engineers often do not see the cultural forces and assumptions in what they are reading or writing, because they live in them like fish in water.
It's not good thinking to disregard information from history, political science, and culture studies (etc.) as "all that soft, non-quantifiable stuff." If we ignore the soft stuff, we can't see how it is influencing and biasing us.
That does not mean that every humanities class is great. Just that they do bring us a type of knowledge that is different in kind from scientific knowledge.
