Youre vulnerable to bias and polarization if you only get your news from one source. So instead of highlighting a single news outlet when you click through to a Trending topic, Facebook will now show a carousel of the other most popular articles written about the subject by different publishers.
Meanwhile, Facebook is giving more exposure to Trending Topics on mobile. Rather than only show Trending topics in the drop-down when you go to search for something on Facebooks mobile app, the company will test showing a box with the top three current Trending topics inside the News Feed. This way people will more likely discover Trending content on mobile when previously it was buried in an unintuitive spot.
Facebook tells TechCrunch that the Trending sources carousel isnt personalized to purposefully show you publishers you dont follow or that might have a contrasting view point to what you typically click and share. But by swiping through to different news sources that you dont follow, the company says it could show you different view points on the same topic.
Of course that could backfire by showing you more biased sources than youd normally read. Not every fact needs an alternative take. That can lead to misguided hot takes and senseless contrarianism. Facebook will have to keep an algorithmic eye on what publishers it shows in these carousels.
Since Trump was elected, Facebook has been criticized for widening the political divide in America. Instead of more generalist media, the News Feed allows people to create their own newspaper from the sources they prefer. But if someone is lured into following biased or sensational sources, and surrounds themselves with friends who do the same along the same political pole, they can have misinformed views reinforced.
Mark Zuckerberg likes to cite a study by Facebook from 2015 that showed 23 percent of users friends are of the opposite political affiliation, while almost 29 percent of stories in the News Feed display views that disagree with a users ideology. But having 70%+ of your feed stoking your existing beliefs can still be problematic. In Zuckerbergs humanitarian manifesto, he wrote that one solution was to show a range of perspectives, let people see where their views are on a spectrum and come to a conclusion on what they think is right.
Facebook recently tried another approach to deflating these filter bubbles by letting people follow a topic and then see posts from a variety of publishers about it instead of just following individual publishers. Todays update furthers that effort. Even if Facebook doesnt truly believe filter bubbles are a massive problem, it needs the News Feed to be perceived as a positive fountainhead of information to stay at the center of peoples web browsing habits.
