Over at the Cultural Cognition Blog, I’ve written a bit about some new evidence about partisan division. The headline news is that partisanship is a better predictor than it used to be of cultural division. But as I read the data, the undernews is that we’re actually no more divided than we used to be on common ideological and cultural measures. Given all that’s happened in the last quarter-century – including media differentiation, the digital revolution and 24-hour news cycle, more bowling alone, sprawl – isn’t that kind of a huge deal? The fact that partisan self-identification is a better predictor of cultural views than it used to be simply means that the parties are cohering better. That might be bad for the functioning of our particular form of representative government, but it doesn’t mean that we’re drifting apart as a country.
