Last week, the first papers from a collaboration between Meta’s Facebook and a crew of exterior researchers learning the 2020 election have been lastly published. Two of those research requested: Are we trapped in filter bubbles, and are they tearing us aside? The outcomes counsel that filter bubbles are at the least considerably actual, however countering them algorithmically doesn’t appear to deliver us any nearer collectively.

Some are decoding these outcomes as proof that Facebook divides us. Others are claiming these experiments are a vindication of social media. It’s neither.

The first study tried to determine whether or not we’re actually in informational echo chambers, and in that case, why. Unsurprisingly, the segregation in our data diets begins with who we comply with. This mirrors offline life, the place most individuals’s in-person social networks are highly segregated.

But what we really see in our Feed is extra politically homogeneous than what’s posted by these we comply with, suggesting that the Feed algorithm actually does amplify the ideological leanings of our social networks.

There are even bigger partisan variations in what we have interaction with, and Facebook, like pretty much every platform, tries to present folks extra of what they click on, like, touch upon, or share. In this case, it seems to be just like the algorithm is type of assembly human habits midway. The distinction in our data diets is partly because of what we’ve chosen, and partly the results of utilizing computer systems to guess—usually accurately—what buttons we’ll click on.

This raises the query of how ideologically comparable folks’s information ought to be. You can learn the computed values of the “isolation index” within the paper, however it’s not clear what numbers we must be aiming for. Also, this research is strictly involved with “news and civic content.” This may be democratically essential, however it makes up solely a few percent of impressions on Facebook. It’s doable that constructive interactions with people who find themselves politically totally different change us probably the most, even when it’s simply studying their posts on unrelated matters.

The second study immediately examined whether or not rising the political variety of individuals and publishers in your feed has an impact on polarization. For about 20,000 consenting individuals, researchers decreased the quantity of content material from like-minded sources by a few third. This elevated consumption from each impartial and cross-cutting sources, as a result of the period of time spent on Facebook didn’t change.

Of the eight polarization variables measured—together with affective polarization, excessive ideological views, and respect for election norms—none modified in a statistically vital means. This is fairly good proof towards probably the most simple model of the “algorithmic filter bubbles cause polarization” thesis.

But this isn’t the top of the story, as a result of filter bubbles aren’t the one mind-set concerning the relationship between media, algorithms, and democracy. A review of hundreds of studies has discovered a constructive correlation between normal “digital media” use and polarization, worldwide, in addition to a constructive correlation with political information and participation. Social media use has many results, each good and dangerous, and filter bubbles aren’t the one mind-set concerning the relationship between media, algorithms, and democracy. For instance, there’s proof that engagement-based algorithms amplify divisive content, and instruments to succeed in focused audiences may also be used for propaganda or harassment.
