Vox Day: The science, she is about as settled as science can get. No hockey sticks,
just a clear picture of what a 1 SD delta looks like. Steve Sailer has more.

They found a database of
1,369 American kids, average age 11 or 12, for which they have both genes,
allowing them to look racial ancestry (horizontal axis) and scores on an
IQ-like test of cognitive ability (vertical axis).
Among those who
self-identified as black (blue dots) and white (red dots), there wasn’t much
overlap. There’s one red dot way off in the nonwhite section and about a dozen
people near 50/50 white/nonwhite. But even though the Economist says there is no doubt vast
confusion over self-identification, there actually isn’t much. Two individuals
are self-identified as white who are less than 50% white by genetic ancestry
estimate (one substantially, one marginally). And two individuals are
self-identified as black who are more than 50% white, but none more than about
5/8ths white.
In general, even among the
new generation, there aren’t all that many people who are mostly white but
partly black.
A couple of things to keep
in mind is that these are children and the self-identification is probably done
by their parents. Parents in mixed marriages are more likely, I imagine, to
pick “Multi-Ethnic” for their children. In contrast, children can have strong
opinions. For example, in 2010 President Barack Obama told the Census that he
wasn’t white, just black.
