On partisan "Echo Chambers"

The 2022 article was inspired by ongoing discussions on “echo chambers,” the idea that the media exposes people to overwhelmingly partisan and like-minded news content. To gauge the scale of the echo chamber problem, we asked: how many people have a news diet that is made of majority highly partisan sources? The figure below is somewhat unique because we present results corresponding to multiple definitions of “majority”--50% and 75% of an individual’s total news consumption. You can also adjust the “strictness” of the highly partisan content definition with the lenient/stringent button.

Note- we only capture internet browsing on desktop computers—not mobile devices, so it is conceivable that people see even less or much more partisan content on their mobile devices.
