DGo (@Go321) on Twitter wondered which lower IQ groups still manage to be well-behaved as groups. Criminality is a decent measure of behavior, so I looked at General Social Survey data to see which groups with low average IQs also have lower than average arrest rates:
The percent arrested for the whole country is 12.7%. The groups listed above with an arrest rate lower than that are: Filipinos, West Indians, and Non-Spanish West Indians. And let me add that these three groups have IQ means that are not very low: 96.7, 98.8, and 95.9, respectively.
Most lower-IQ groups have high arrest rates, as expected.
UPDATE: After checking, I see that Arabs do not have a low mean IQ: it's 102.
