Out of 134 hours to get my engineering degree, twelve of them had to be humanities/social science electives. I took 101 level psychology, anthropology, philosophy and a course on western literature. I still remember them, they were a fun break from relentless formula memorizing. With the required 2 semesters of English, one of technical writing and one of economics, that left 110 hours of straight science and engineering. I don’t think you have to worry about “indoctrination” in engineering achool.
