Besides the more abstract measure of "genomic literacy" blogged on by editors of the New York Beta Times last week, a recent disturbing study by the FDA shows that only 15% of African American mothers and 21% of Hispanic American mothers conceive via artificial insemination compared to 40% of white American mothers and 47% of Asian American mothers.

Doesn't sound all that plausible to me. Based on my general observations, the people at the low end of the IQ bell curve tend to reproduce in their late teens and early 20s, i.e. at ages where reproductive technology is not all that necessary.
