Good question. It’s hard to tell exactly, but there’s lots of evidence that the rise in “affective polarization” (dislike of the other side) is linked to “partisan sorting” (or “ideological sorting”)—the fact that people within political parties increasingly agree on more and more things, and also socially interact with each other more. Lilliana Mason has some good work on this (and Ezra Klein got a lot of his opinions in his book on this from her).
This paper raises some doubts about the link between the two, though. It’s hard to know!
