Race and IQs

[Anomalocaris]

Is it possible to identify a clear and substantial subgroup inside the larger group identified above as East Asians that would have average IQ of 70?  Similarly a clear and substantial subgroup inside the larger African group that would have an average IQ of 105?

If so, how is classifying intelligence by the above racial groupings valid?

That's easy! Just pick one East Asian with an IQ of 70 and one African with an IQ of 105.

Unfortunately, that doesn't invalidate anything.

No.  Not cherry picked individuals.  Is there any substantial and otherwise identifiable groupings within each of the above racial classifications that exhibit evidence of significant and heritable average IQ differences from the average calculated for that racial group.

If there is, than race is not a most meaningful grouping for the purpose.

That depends on why you believe in their validity.  

Is it because you’ve equipped yourself with the background and experience to assess the quality of data and the validity of the methodology?

Is it because you’ve surveyed the professional view?

Is it because it appear to support to your personal impression formed from your own interactions?

Is it because it support the assertions of some one whom you wish to emulate?

It is because treating it as valid is more satisfying?

It's mainly because I'm not in the habit of refuting scientific theories (like evolution) even if the implications are unpalatable.

Why?  Science is all about refuting scientific theories.    Only when everything that can reasonably and soundly be done to refute a theory has been done, and the theory still somehow remains unrefuted, could the theory be grudgingly and conditionally accepted.

That is what distinguish real science from faith, religion or pseudoscience.
