A class project at Princeton <http://freedom-to-tinker.com/2017/09/19/breaking-your-bubble/>: In the first step, students measured their filter bubble. More specifically, for homework, at three different time points each week, they scrolled through their feeds until they found five political posts (ads included). Then, they coded these posts as either liberal, neutral, or conservative. Students also kept track of how many posts they had to scroll through to get to five posts as a measure of how much political content was in their feed. ... In the second step, the students developed and implemented a procedure to break their bubble. Their goal was to achieve a “balanced diet” of liberal, neutral, and conservative political content that matched the baseline distribution of what is being shared on Facebook ... Followup <http://freedom-to-tinker.com/2017/09/19/what-our-students-found-when-they-tried-to-break-their-bubbles/>: So, were students able to break their bubble? Initially, we expected that because the News Feed algorithm is complicated, it might be hard for students to break out of their bubbles. But we were wrong. The class was able to move to a more balanced diet pretty quickly.
