I believe that the increase in black IQ is due to the increase in mixed couples.

A reasonable hypothesis!

Thanks for a good thread.

Yes, the main article was stellar, but the comments were also distinctly above average (by at least one Standard Deviation)!

The mean IQ of the continental sub-Saharan is 70. The African-American average is 85, due to white admixture.
