Physics and those parts of other fields that grow out of physics - chemistry, the structure of big molecules - in those domains, there is a lot of progress. In many other domains, there is very little progress in developing real scientific understanding.
There's an interesting book about that called The Third Reich and the Ivory Tower, written by Stephen H. Norwood. It has a long discussion about Harvard, and indeed the school's president, James Conant, did block Jewish faculty. He was the one who prevented European Jews from being admitted to the chemistry department - his field - and also had pretty good relations with the Nazis.
There is a noticeable general difference between the sciences and mathematics on the one hand, and the humanities and social sciences on the other. It's a first approximation, but one that is real. In the former, the factors of integrity tend to dominate more over the factors of ideology. It's not that scientists are more honest people. It's just that nature is a harsh taskmaster. You can lie or distort the story of the French Revolution as long as you like, and nothing will happen. Propose a false theory in chemistry, and it'll be refuted tomorrow.
Chemistry, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn't reduce to physics. So it's just some way of calculating the result of experiments. The Bohr atom was treated that way.
It's roughly the case that if systems become too complex to study in sufficient depth, physics hands them over to chemistry, then to biology, then experimental psychology, and finally on to history. Roughly. These are tendencies, and they tend to distinguish roughly between hard and soft sciences.
