The two sides are not equal : fake and hyperpartisan news is much worse on the right

Our analysis challenges a simple narrative that the internet as a technology is what fragments public discourse and polarizes opinions, by allowing us to inhabit filter bubbles or just read “the daily me.” If technology were the most important driver towards a “post-truth” world, we would expect to see symmetric patterns on the left and the right. Instead, different internal political dynamics in the right and the left led to different patterns in the reception and use of the technology by each wing. While Facebook and Twitter certainly enabled right-wing media to circumvent the gatekeeping power of traditional media, the pattern was not symmetric.

The size of the nodes marking traditional professional media like The New York Times, The Washington Post, and CNN, surrounded by the Hill, ABC, and NBC, tell us that these media drew particularly large audiences. Their color tells us that Clinton followers attended to them more than Drumpf followers, and their proximity on the map to more quintessentially partisan sites—like Huffington Post, MSNBC, or the Daily Beast—suggests that attention to these more partisan outlets on the left was more tightly interwoven with attention to traditional media. The Breitbart-centered wing, by contrast, is farther from the mainstream set and lacks bridging nodes that draw attention and connect it to that mainstream.

Moreover, the fact that these asymmetric patterns of attention were similar on both Twitter and Facebook suggests that human choices and political campaigning, not one company’s algorithm, were responsible for the patterns we observe. These patterns might be the result of a coordinated campaign, but they could also be an emergent property of decentralized behavior, or some combination of both. Our data to this point cannot distinguish between these alternatives... The primary explanation of such asymmetric polarization is more likely politics and culture than technology.

What we find in our data is a network of mutually-reinforcing hyper-partisan sites that revive what Richard Hofstadter called “the paranoid style in American politics,” combining decontextualized truths, repeated falsehoods, and leaps of logic to create a fundamentally misleading view of the world. “Fake news,” which implies made of whole cloth by politically disinterested parties out to make a buck of Facebook advertising dollars, rather than propaganda and disinformation, is not an adequate term. By repetition, variation, and circulation through many associated sites, the network of sites make their claims familiar to readers, and this fluency with the core narrative gives credence to the incredible.
