>The minimum IQ required to graduate college (and even some masters degrees) with decent grades can’t be much more than 100 at this point, but was certainly more like 115 or even 120 in the 1950s.
IQ is in practice affected by education (to a small extent and mostly in early childhood), but the whole point of it as a concept was to avoid measuring education. So I don't think it follows that higher IQ = more educated.
That's not what he's saying, he's saying collage is too hard to graduate and get good grades with an IQ less that a bit over 100 now, and that number was more like 115 in the past.
