Cheers to FREAKONOMICS BLOG » New evidence on racial test score gaps for stepping into a controversial, but vital question at the heart of genetics. We know that test scores vary by race among adults, and that a statistically significant variance shows up early. Is environment responsible; is it innate? Even if you insist that "IQ" is not a relevant measure, please explain why there would be a difference. If it's upbringing, then the younger you are, the lower the difference, right?
So they studied a large data set of cognitive tests given to 8-12 month old babies and published a paper last month with the results. Answer: they couldn't find a difference between black and white babies, but they did see very slightly lower scores for Asians.
