…The best way to attract and grow an audience for political content on the world’s biggest social network is to eschew factual reporting and instead play to partisan biases using false or misleading information that simply tells people what they want to hear.

…People who regularly consume information from these pages — especially those on the right — are being fed false or misleading information.

The nature of the falsehoods is important to note. They often take the form of claims and accusations against people, companies, police, movements such as Black Lives Matter, Muslims, or “liberals” or “conservatives” as a whole. They drive division and polarization. And in doing so, they generate massive Facebook engagement that brings more and more people to these pages and their websites and into the echo chamber of hyperpartisan media and beliefs.

…However, during the time period analyzed, we found that right-wing pages were more prone to sharing false or misleading information than left-wing pages. Mainstream pages did not share any completely false information, but did publish a small number of posts that included unverified claims.

…Alarmingly, we found examples of pages on the left and on the right presenting fake [i.e satiric] news articles as real.

…While the majority of the posts we rated from the partisan pages were mostly true, the mostly true posts typically did not perform as well as ones that were mostly false, were a mixture of true and false, or had no factual content. The more overtly partisan, misleading, or opinion-driven a post was, the more engagement the post would see, according to our data. Facebook, and the people using it, appears to reward the worst tendencies of these pages.

…One thing we noticed when trying to fact-check posts was that these pages, and the websites connected to them, largely aggregate information from elsewhere. That wasn’t surprising. What was notable was that the right-wing pages almost never used mainstream news sources, instead pointing to other highly partisan sources of information. Even if the key information they were covering originally came from a mainstream source, they almost always linked to other partisan sources, which in turn often did the same.

…This was a contrast with the left-wing pages, which frequently pointed to articles from mainstream sources. Some may view this as validation of the long-held view of conservatives that mainstream media has a liberal bias. It’s also important to note that the right-wing pages we analyzed had a much higher percentage of false and misleading information compared to the mainstream and left-wing pages.

Based on our analysis, we found the hyperpartisan right-wing echo chamber to be more polarized than its counterpart on the left, and our sense is that this likely contributes to the tendency for right-wing Facebook pages to promote false and misleading information.

…Devoted readers of these pages likely experience a version of the same echo chamber effect. The more they read and engage with these pages, the more Facebook will show them this content in their News Feeds. The more they click on the hyperpartisan websites, the more Google will show them search results from these sources. The result is that over time people will likely become more polarized because algorithms and friends continue to feed them information that pushes them further in this direction. This “group polarization” phenomenon is well-documented and has been shown to exist in studies of Facebook users.

…The reality is that people who frequent these hyperpartisan pages on the right and on the left exist in completely different segments of the online world, rarely interacting with or seeing what the other side is seeing. The more they rely on these pages for information, the more polarized they will likely become — and the more their worldviews will be based on information that is misleading or completely false.
