What Facebook Did to American Democracy - The Atlantic
▻https://www.theatlantic.com/amp/article/542502
We’ve known since at least 2012 that Facebook was a powerful, non-neutral force in electoral politics. In that year, a combined University of California, San Diego and Facebook research team led by James Fowler published a study in Nature, which argued that Facebook’s “I Voted” button had driven a small but measurable increase in turnout, primarily among young people.
Rebecca Rosen’s 2012 story, “Did Facebook Give Democrats the Upper Hand?” relied on new research from Fowler, et al., about the presidential election that year. Again, the conclusion of their work was that Facebook’s get-out-the-vote message could have driven a substantial chunk of the increase in youth voter participation in the 2012 general election. Fowler told Rosen that it was “even possible that Facebook is completely responsible” for the youth voter increase. And because a higher proportion of young people vote Democratic than the general population, the net effect of Facebook’s GOTV effort would have been to help the Dems.
The potential for Facebook to have an impact on an election was clear for at least half a decade.
The research showed that a small design change by Facebook could have electoral repercussions, especially with America’s electoral-college format in which a few hotly contested states have a disproportionate impact on the national outcome. And the pro-liberal effect it implied became enshrined as an axiom of how campaign staffers, reporters, and academics viewed social media.
How Facebook’s news feed algorithm works.

very time you open Facebook, one of the world’s most influential, controversial, and misunderstood algorithms springs into action. It scans and collects everything posted in the past week by each of your friends, everyone you follow, each group you belong to, and every Facebook page you’ve liked. For the average Facebook user, that’s more than 1,500 posts. If you have several hundred friends, it could be as many as 10,000. Then, according to a closely guarded and constantly shifting formula, Facebook’s news feed algorithm ranks them all, in what it believes to be the precise order of how likely you are to find each post worthwhile. Most users will only ever see the top few hundred.

No one outside Facebook knows for sure how it does this, and no one inside the company will tell you. And yet the results of this automated ranking process shape the social lives and reading habits of more than 1 billion daily active users—one-fifth of the world’s adult population.
