This graph is taken from a new study of more than 11,000 people. You can see that, while increasing SES lowers the risk of incarceration only a little bit, increasing IQ lowers the risk sharply.
So much for the liberal claim that social class is everything.

Someone in that study got a little too excited about getting a copy of Matlab. Is there any reason they needed to show a large convoluted 3D graph for a linear relationship? I think it would have been enough just to write down the empirical coefficients.
The authors make a big deal about the interaction effect (i.e., how the effect of one variable depends on the level of the other) but your point is well-taken.
You can just write the interaction effect with a coefficient too, particularly with a two-variable model.
z=a+bx+cy+dxy
See?
And yes, you're right about atheists. That's the reason I'm atheist but not anti-religion; it's good for society and individual people, even if I don't believe in God myself. Even among people high-IQ enough to stay out of trouble, I'm willing to believe atheism has negative effects...
