Continuing with the Yale vs UConn example, 8.0% of UConn grads planned a PhD/MD/JD soon after graduation compared to 8.5% of Yale grads – not a dramatic difference. However, there was a difference in distribution of these 3 degree types, with Yale grads more likely to pursue law than other colleges. This fits the Yale law school connection and differences in distribution of majors.
I do think that satisfaction in career opportunities with only a bachelor’s plays a role, as does the larger portion pursuing finance and consulting – fields that typically do not require graduate degrees for initial employment.
