With items overlapping on the two lists, it appears that only 18 “majors” were included - several are generalized grouping of several majors.
The comments are interesting, but keep in mind they only represent those that regretted their major. I don’t think CS has limited job opportunities as a whole - just among those with regret. There is certainly a correlation/causation issue there. I also found little requirement for advanced degrees in my engineering career.
Pure sciences being at the top may surprise some who consider “STEM” to be a homogeneous grouping. And Education being near the top is sad but accurate.
