Why is it that height is highly heritable but intelligence is much less so?
If you have a couple who are 190cm and 182cm respectively, their kids will almost certainly be giants.
If you have a smart couple, say two college professors, their kids will be smart, however it seems to me that often times they will not be smarter than their parents. I.e. there is regression towards the mean.
Now what I find puzzling is, why isn't there also regression towards the mean in heritability of height?

I'm quite sure there is.
