Race, extraversion, and crime: Using last post's measure of extraversion, I wonder if it could help explain racial differences in crime. Ever getting arrested is the dependent variable. Here are the logistic regression coefficients, and I'm comparing two groups at a time:
Logistic regression coefficients
Whites and Asians (N = 3,087)
Blacks and Asians (N = 468)
* p < .01, two-tail test
Compared to Asians, whites are more likely to get arrested, but the difference becomes non-significant when extraversion is entered into the equation. The exact same thing happens when we compare blacks and Asians. So the evidence here suggests that extraversion helps explain the racial gap in criminality.
But why, you ask, would extraversion raise the risk of breaking the law? Compared to, say, the guy who likes to spend his time blogging alone, people who love to be out doing things with other people are more likely to find themselves in situations conducive to crime. And they would be less likely to back away from criminal opportunities.
