Eliminating feminist teacher bias erases boys' falling grades, study finds
Second, this article says nothing about university and since universities predominantly grade their students by written examinations, the discribed form of bias is certainly reduced.
Third, the professor cited is an economics professor. Let's be careful and say that education and didactics are not the primary expertise of economical sciences. It is a paper from a reputable source though. The website is not a good source on the overall paper. The original abstract of the paper says:
Boys who perform equally as well as girls on reading, math, and science tests are graded less favorably by their teachers, but this less favorable treatment essentially vanishes when noncognitive skills are taken into account. For some specifications there is evidence of a grade “bonus” for boys with test scores and behavior like their girl counterparts.
