Race, ethnicity, and IQ according to ADD Health

The ADD Health Study gave teenagers a five minute vocabulary test and converted scores into a measure of IQ. (As a reader pointed out in an earlier post, vocabulary accurately captures general intelligence). Here are mean IQ scores for all kids who were born in the United States (non-Hispanic whites are set at 100, and the standard deviation is 15):



















Jews are heads and shoulders above other groups. Jews and blacks, in fact, are 1 1/2 standard deviations apart--an enormous difference. Except for Koreans, all Asian groups score lower than whites, and Filipinos are toward the bottom of the list. All Hispanic groups have lower averages. Mexican Americans are nine points lower than whites.

  1. Boy, I sure am glad that Jews aren't ethnocentric or the upper IQ portions of other ethnic groups would be in big trouble.

    Does anyone have an idea if reading to a child can boost that child's IQ?

    A buddy of mine started reading to his little girl when she was very young. She is about to run seven. He told me that she can open and read his emails, she writes in complete sentences, and she reads her own little children's books aloud. If you didn't know better, according to him, you'd swear she was about 12 years old just by listening to her.

    Asian verbal intelligence is lower than their visuospatial intelligence, whereas the opposite is true for Jews.

    Vocabulary tests *might* be a good measure of intelligence for white kids (I really don't know if I buy that), but non-whites, especially those raised in a bilingual household, might not score as well. I wouldn't think that is because they are less intelligent, but because they had to navigate two languages, regardless if they were born in the US. Did you incorporate what language(s) they spoke at home into your results? Rates of poverty also play a very big role in vocabulary, and non-whites poverty rates are much higher than white poverty rates. This is important when lumping all Central Americans into a category and calling them less intelligent *as a group*, when really they are just held at a disadvantage that would be erased if they were not raised in low-income households.
