Note that the paper observes: "liberals tend to be connected to fewer friends who share information from the other side, compared to their conservative counterparts: 24% of the hard content shared by liberals’ friends are cross-cutting, compared to 35% for conservatives" The more articles that I can't agree with I find in my feed, the less likely I am to click on one of them than a guy who sees them less often. Even if we both read exactly 3 such articles a week.
