Math is abstract, but it's also very strict. So strict that you can formalize it and make computer do math. Give it axioms, rules of deduction ("A, A->B. Then B") and he'll traverse the possible reasoning chains.

Besides "matters of interpretation" which are truly a big thing, there is a huge collision of interests.
People found ancient ruins in Palestine. When were they built and by whom? It's not a matter of interpretation, it's an objective question. And still it's impossible to treat it objectively. "I'm employed in American university, I want money for my family, so I'll try to find arguments why it's Israelis". "I'm employed by Chinese academy, I'll do everything possible to prove that it was Arabic town". In physics all people are interested in finding the truth. In history people don't really care who built the town, there's little practical benefit in it, but they care a lot about their ideological leverage.
This is what STEMcels often don't understand. They treat humanities as pure science, while it's more like speeches in court. And it's good if there are prosecutor and defense lawyer, then they'll restrain each others' bullshit a bit. But if only one side is present? Then you have to listen to what they say while paying attention to obvious omissions and contradictions.
