Do you have a link or a specific quote to what was said?. Stanford currently has a record number of faculty in the humanities and sciences school and in the process of opening a new humanities themed dorm, which largely relates to the success of the SLE program – a special program that targets students who are especially interested in humanities. There are also an increasing number of classes and special programs that combine STEM and humanities, such as the new CS + humanities joint major (see https://undergrad.stanford.edu/academic-planning/majors-minors/joint-majors-csx ).
Similarly, my experience at Stanford was quite different. For example, I took a good number of psychology courses. In the early classes, I recall being amazed by how many of the prominent names in my psychology textbooks were members of the faculty, which probably contributes to why Stanford is usually ranked as the top university in the US in psychology. One could make similar statements for other non-STEM fields, but the point is none of this gives the impression of a university that is not concerned about non-STEM faculty or facilities.
It’s true that a a larger portion of students do major in STEM related fields than in the past at Stanford, as well as at most other highly selective colleges. 10 years ago, the major distribution was roughly half STEM, half non-STEM; while the current distribution is roughly 1/3 CS or engineering, 1/3 other STEM related (I am including things like Human Biology; Economics; and Science, Technology, and Society), and 1/3 non-STEM related. CS in particular has had a large increase during the past decade, becoming Stanford’s most popular major. However, decreasing in popularity does not mean that Stanford only cares about STEM, or non-STEM majors are treated as 2nd class citizens. I think this change more relates to the external environment and culture. For example, if a student can earn a 6-figure starting salary in CS at a company that has a reputation for being a fun place to work and a job that society thinks highly of, that can be an enticing option.
Stanford has career/internship services specific to non-STEM majors, but there will always be more demand for certain majors than others from external companies, which largely relates to the boom in CS recently, as touched on above. Note that this demand is not a strict STEM/non-STEM division. For example, prior to the recent CS boom, HumBio was Stanford’s most popular major even though various career stats such as starting salary, suggest no advantage over typical non-STEM majors from a career prospective (without grad degrees, a large portion or both HumBio and non-STEM majors qt Stanford pursue grad or professional degrees).
