Does this correlate with the increase in polarization? I know Jonathan Haidt has spoken about his research on the increase in polarization is America.
If that correlation exists, it may point to an alternative hypothesis to the GP claim that the issue is rooted in those coming from "low trust" societies and due to an internal mechanism.
This gets back to my other statement where people seem to ignore Jim Crow laws and the segregated south. How much more “polarized” can people be than literally being forced by law to do everything separately?
His analysis was within the context of social media driving polarization, so why would you expect it to look at the Jim Crow era? It seems like you’re starting with a conclusion and working backwards.
