This only makes sense if your underlying assumption is that the less violent are reproducing more offspring now. Your reference study merely shows that the phenotypical traits have a strong correlation with the behavior traits (in at least foxes). This selection requires offspring but its seems the parent is referencing a hormonal change due to social behavior.

I agree with the premise, that social and environmental norms can influence hormones, but the fox study is a different phenomenon altogether.

I wouldn't rule it out. After a generation of anti-bullying and zero tolerance schools have gotten pretty good at making sure anyone with even the slightest violent tendencies is primed to be caught up in "the system" by the time they're done and we've thrown the "fuck the government I smoke what I want" crowd in prison.

Agreed. I wouldn't rule it out for mid to long term trends.
