@IWFBuckley by the way, regarding randomness, a lot washes out when you average out large groups. You're usually left with mostly genetics

@IWFBuckley do you mean 20% environment? On an individual basis, the heritability of IQ is 60-85%, with the remainder mostly random

@IWFBuckley on a group basis, like the black-white test score gap, my guess is it's over 90% genetic plus just a little environment.
