I think I’ve talked about it before on other posts, but I once had an anthropology class that, completely unintentionally, was all women and one man, and he dropped the course after two weeks. The other section of the same anthropology class, taught by the same professor, was mixed with men and women. So, since it was anthropology, she asked if it was cool if she took notes. She said right away that the all female class had a wildly different vibe, that we spoke and acted differently and had different social expectations of her and the rest of the class, and that we let students complete their thoughts before disagreeing, while the mixed class was highly traditional and almost entirely male dominated because every time a woman spoke, a man jumped in halfway through to “correct” her by saying the same thing. Its a very small sample size, but I think about this a lot
