Well Paul, my note on Kristof's article had to do with what appears to be rather dodgey statistical assumptions, not color-consciousness or our innate tribalistic impulses.  In other words, does the study adequately control for all the other factors involved, such as the ethnic proportionalities of the general population being tested?  Are there, just possibly, alternate explanations for the patterns we see - other than vicious racism?

"I’d like to read something longer by Sowell"  ---  I'd recommend his "Ethnic America", which should be on everyone's history shelf right alongside Howard Zinn.  ;-)

Thanks for your words, Paul.
