So to summarize, none of the recent posters here agree with the premise of this article (https://www.outsidethebeltway.com/why-more-americans-dont-major-in-the-math-and-science/) that to major in math/science is tough and lots of folks switch out of math/science in part because they may not be capable of completing the major and in part to have an easier time in college and get better grades.
Also none of the recent posters are astonished, like the writer of the article that the MIT grad with the B average in STEM did worse than NYU english major. Data10, reading over the phrase “B average in STEM”, I see now that it is possible that this meant that the MIT grad had a B average overall, but I interpreted this to mean a B average in STEM courses.
The whole point of the article is to talk about averages–to analyze trends, to talk about typical cases. Typically, STEM courses are tougher than nonSTEM courses. Of course, there are exceptions, but the author is talking about general trends, No one, including the author of the article would be surprised if the NYU english major did well in law school admissions if he/she had recently written 2 award winning novels, and was in the top 1 percentile in LSAT scores. Of course there can be incredibly intelligent students at all schools. Perhaps, there’s even an out-of-school janitor who’s also a math genius roaming the halls at MIT who can correct mistakes in the math proofs that have been scribbled in various classrooms.
Also of course, in the example given in the article there is not enough information to know if that ONE specific MIT grad is more capable than that ONE specific NYU grad. That’s not the point. It’s not the premise of the article, nor the seed of my question. The premise/question was a what-if based on the average/typical case. To rephrase and be more specific: would it be surprising if a cohort of 100 consecutive MIT grads majoring in STEM with a mean GPA of say 3.3 (with a science/math gpa of 3.0), ON AVERAGE, did less well on law school admissions than a cohort of 100 consecutive NYU english majors with a mean GPA of say 3.8? (The article does not say the NYU grad had a 4.0, but merely implied his/her gpa was higher than the MIT grad). The author of the article and I would say, no, this is not surprising, in large part, because of the importance of the GPA in professional school admissions, regardless of the difficulty of the curriculum.
The implication in the article, however, is that again on average, the 100 MIT STEM grads are at least as capable (and perhaps more so) than the 100 NYU nonSTEM grads with higher grades. The article after all describes the phenomenon of relatively bright students who can’t complete a STEM major who then do better (in terms of GPA and future professional school admissions) by switching to easier non-STEM majors. There would be no point to the article if the message was simply, it’s obvious that students with higher GPAs are just more capable that students with lower GPAs regardless of the major and school tier.
Based on graphs from the reference below, it appears that students that start off as science majors are close to 3 times more likely to change their major compared to those who start off as humanities majors
