RUTHLESSLY PRICKING YOUR GONFALON BUBBLE:

How Our Media Bubble Protects Our Ideologies : Almost all of the news and opinion we consume comes from outlets and commentators who share our politial beliefs. (Lisa Wade, 9/13/16, Pacific Standard)

How are media sources from opposing sides of the political spectrum covering the election? Most of us have no idea. We live in a media "bubble," one in which we usually only consume "friendly" material: news and opinion from outlets and commentators who share our lean.

At Facebook, employees followed a sample of 10.1 million users who publicly identified their political leanings. They then looked at the forces that created the bubble: (1) "ideological homophily," the degree to which friends shared the same leanings; (2) Facebook's algorithm, feeding you things it thinks you want to see; (3) and click-through behavior--which links were ignored and which attracted interaction.

They concluded that "individuals' choices played a stronger role in limiting exposure" to politically diverse content than did their algorithm. (You can get the data yourself here.)

At the Wall Street Journal, you can take a look at these different media bubbles side-by-side. They frame the data as what you might see in your Facebook feed if most of your friends identify as "very liberal" or "very conservative." More broadly, what the data represents is the use of Facebook data as an insight into the bigger media bubbles we all live in both on- and off-line.
