Inductivist

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.   

The plot thickens: As a follow-up to the last post, I wanted to see if the risk of arrest varies by hair color. I found that people with red or salt and pepper hair had the highest rates of arrest when stopped. As I wrote before, 4.1% of the entire sample was arrested.


Percent with red hair who were arrested

Black 10.9
White Hispanic 10.9
White 6.7
All cases 8.0


Percent with salt and pepper hair arrested

Black 7.8
Black Hispanic 8.7
White Hispanic 9.1
White 7.8
All cases 8.0

When I saw the number for red-headed blacks, my first thought was Malcolm X. Then I remembered an analysis I did of GSS data which showed that Scottish Americans are angrier people than blacks. (The Irish, not so much). And I have no idea on folks with salt and pepper hair. It's most common among whites. You guys gotta help me out with an explanation.

I charge the NYPD with gingerism--prejudice against redheads.
