### That does not seem to be the case. Standard deviations of IQ among
Africans are not grossly different from other groups.

### IQ tests are valid predictors of academic achievement (for which they
were invented) among all major groups tested. Nonverbal tests such as
progressive matrices do not show scores comparable with ours among black
Africans (ranging from 60s' to 80s, among dozens of studies), although
overall they tend to have a lower g-loading if used among Africans than
among whites (0.55 vs 0.8).

### Yes, you can compare the data and IQ among black Americans is on
average higher than among African blacks (85 vs 70's).

### You would need to explain why American blacks have now higher scores
than African blacks.
