There has never been a time when our nation wasn’t divided by partisanship. Yet some eras are more divisive than others, and few of us would deny that we’re living through an especially polarized time. For those who don’t trust their instincts on this question, numerous surveys bear out a collective hunch: polarization really has gotten worse in recent decades.
We don’t lack for probing examinations of the causes. Ezra Klein blames modern social and news media. Charles Murray notes that ordinary class divisions have become intensified through American “super zips.” Some studies blame the nationalization of local politics, while others suggest that even our leisure activities are exacerbating political divides. Predictably, each side blames the other for increased radicalization within their respective political parties.
