  You might enjoy this essay from C. Thi Nguyen on the distinction between filter bubbles and echo chambers—"In epistemic bubbles, other voices are not heard; in echo chambers, other voices are actively undermined."—and why the latter might be a more accurate diagnosis of the problem:

  "Crucially, echo chambers can offer a useful explanation of the current informational crisis in a way that epistemic bubbles cannot. Many people have claimed that we have entered an era of ‘post-truth’. Not only do some political figures seem to speak with a blatant disregard for the facts, but their supporters seem utterly unswayed by evidence. It seems, to some, that truth no longer matters.

  This is an explanation in terms of total irrationality. To accept it, you must believe that a great number of people have lost all interest in evidence or investigation, and have fallen away from the ways of reason. The phenomenon of echo chambers offers a less damning and far more modest explanation. The apparent ‘post-truth’ attitude can be explained as the result of the manipulations of trust wrought by echo chambers. We don’t have to attribute a complete disinterest in facts, evidence or reason to explain the post-truth attitude. We simply have to attribute to certain communities a vastly divergent set of trusted authorities.

  Listen to what it actually sounds like when people reject the plain facts – it doesn’t sound like brute irrationality. One side points out a piece of economic data; the other side rejects that data by rejecting its source. They think that newspaper is biased, or the academic elites generating the data are corrupt. An echo chamber doesn’t destroy their members’ interest in the truth; it merely manipulates whom they trust and changes whom they accept as trustworthy sources and institutions.

  And, in many ways, echo-chamber members are following reasonable and rational procedures of enquiry. They’re engaging in critical reasoning. They’re questioning, they’re evaluating sources for themselves, they’re assessing different pathways to information. They are critically examining those who claim expertise and trustworthiness, using what they already know about the world. It’s simply that their basis for evaluation – their background beliefs about whom to trust – are radically different. They are not irrational, but systematically misinformed about where to place their trust."
