In another part of this thread[0], Bartweiss says that Raven's Advanced Matrices is valid up until about 150 IQ. So I was close. And my bigger point is that, though the measurement lacks precision at that level, if you lined up a bunch of 150 IQ people and a bunch of 160 IQ people, there are probably some aggregate group differences. Anecdotally, I've spent a lot of time around really smart people. There are gradations even at the top (just as there are in all other areas of talent; there's only one Lebron James, after all)
