Maybe this is a GD, but I do hav two specific GQs. My apologies; I know this has come up before, but…

What specific errors, if any, did Murray and Herrnstein make in the “Bell Curve” with respect to their statistical analysis of the data in terms of the data, data sets, stat bias, group bias, or whatever? This is assuming assumptions about race are true.

Holding 1 steady and assuming they made no statistical errors, what errors did they make in terms of their assumptions around race and the nature of IQ heritability?
If anyone wants to DEFEND “The Bell Curve,” take it to GD I’d just like an answer to 1 and 2.
It’s a big question. Moderators, my apologies if this is in the wrong place, but I was looking for a specific answer(s) and figured I may as well start it here.
