Are you starting to notice a pattern of Greg turning out to be right? Does that reduce your confidence in other areas where he claims something you think is wrong?

I think the evidence for the existence of different cognitive adaptations is weak, and that culture and environment are sufficient explanations for the data.

Is there evidence that culture is MORE important than adaptations? A reasonable person might be agnostic between explanations in the absence of evidence, rather than assuming it must be entirely one or the other.

So Occam's Razor points to culture alone. But I grant that brain adaptation *could* have happened. I just don't see clear evidence of brain differences between populations.

> I just don't see clear evidence of brain differences between populations. So differences in brain volume and neuron count just don't count? Or are those caused by "culture"?

Rather than linking to the essay on "bingo" again, I'm going to ask: what is your problem with measurement? Are you pro-ignorance?

You're trying to make a triple bank-shot of invalid (or at best very weak) inferences: 1. No-one cares about brain volume in itself 2. You're claiming brain volume is correlated with IQ

I'm bringing up brain volume as a counter to the argument that differences are just cultural. We know that's not the case.

We know there are physiological difference between ancestry groups, that's not contentious. It doesn't mean anything unless you can connect it to the issues that *are* in dispute.

Right, there are physiological differences and the brain is a physical organ and there are known physiological differences in group average brains. Physiological differences in legs, arms and organs are caused by selection for different traits - obviously the same for brains.
