I've heard repeatedly that the correlation between IQ and achievement after about 120 (z = 1.33) is pretty weak, possibly even with diminishing returns up at the very top.

Is this what you intended to say? "Diminishing returns" seems to apply at the bottom the scale you mention. You've already selected the part where returns have started diminishing. Sometimes it is claimed that that at the extreme top the returns are negative. Is that what you mean?

Yeah, that's just me trying to do everything in one draft. Editing really is the better part of clear writing.

I meant something along the lines of "I've heard it has diminishing returns and potentially [, probably due to how it affects metabolic needs and rate of maturation] even negative returns at the high end."
