Many aren't aware of the smaller SD (~13; quite similar to that of e.g. Finns and NE Asians) of Blacks, compared to that of whites (15). One very interesting fact: black females have higher avg IQ than black males; this in unlike in any other major population group.

Replying to @a_centrism @MatsVinnaren
I expect that it's genetic for the same reason as the male > female gap for the other races. In evolutionary time, obtaining calories to feed children in Africa is done by women so they're selected to deal with that challenge - unlike Eurasian women who were dependent on men.

Shorter version - the ornamental sex of a race is going to have the lower IQ because there's weaker relative selective pressure for intelligence.
