Recently, there has been a fair amount of controversy over whether Facebook has been suppressing conservative stories in its much-clicked list of trending topics. But users of the nigh-inescapable social media site know that plenty of political commentary, ranging from anarchist to reactionary, winds up in the average user’s timeline before long no matter what the site’s internal algorithms may warrant. Want to know what a high school classmate thinks of abortion? She’ll definitely let the world know on her wall, without being asked. For some reason, relatives, neighbors, and half-forgotten acquaintances from the distant past are not shy about expressing their political affiliations to the world, especially during a bitterly contentious election year with several polarizing candidates in the running. Recently, the staff of The Wall Street Journal have been examining the role social media might be playing in politics, so they’ve created two contrasting Facebook feeds: a red one for conservative views and a blue one for liberal views. Theoretically drawing from the same set of facts, the two feeds differ wildly in their coverage of, for instance, Bernie Sanders.
