"I think it’s the idea that people are not billiard balls. They’re not impacted on by forces like cold fronts in the weather and react accordingly. They actually think about what they’re doing. For example, criminals are conscious of what they’re doing and they respond to incentives. And they have a culture—they have beliefs about what they’re doing"

If criminals got this idea from anyone, it's leftist academics. It's called determinism, or the denial that free will exists. It also denies good and evil, responsibility for actions, and even personal identity.

In all likelihood, but there is a disturbing number of people on the right who think the same way. Look at the efforts to ban pornography and strip clubs, or against violence in movies, or against offensive language in music. Self-righteous moralists like to think that these things cause people, who ostensibly have no say in the matter, to become wicked. Prohibition, and also the Comics Code (which destroyed the comic book industry in the 50's) came from paternalistic busybodies on the right.
