But schooling in the US is biased in all sorts of ways, and trying to draw conclusions from that is being encouraged in this discussion.

- hackinthebochs 8y agoTrue, but not all bias is created equal. You have to consider the nature of the potential bias and how it might affect measured outcomes. It's much less clear how bias might unnaturally increase variance than reduce it or alter the mean. But my point was mainly to argue against the conclusion that a lack of observed variance differences in some countries demonstrated the hypothesis false. I agree that the observed variance differences in western countries doesn't prove it true either.
