Season: 1 Episode: 6
Adi, a lawyer and campaigner, explains how campaigns are often thinking about how they can crack into people's filter bubbles in order to raise awareness and find new supporters. During the conversation Elizabeth and Adi tease apart the difference between algorithmically driven filter bubbles and echo chambers which come about as a result of individuals choices in their media environment. Additional Resources:
Eli Pariser has a helpful Ted Talk about his notion of the Filter Bubble: Beware online “filter bubbles”.
This academic article by Dubois (yes, your host) and Blank breaks down the theory of echo chambers and talks about how people's media diets might help them avoid echo chambers: The echo chamber is overstated: the moderating effect of political interest and diverse media.
This Knight Foundation report is a great, accessible, overview of academic research related to echo chambers: Avoiding the Echo Chamber about Echo Chambers.
Early in the episode Elizabeth mentions homophily which is basically the idea of "birds of a feather flock together." The Wikipedia article on homophily is a great place to start.
