Smart people know that echo chambers are hurting this country. Fox News is one such echo chamber. wrote a fifteen page paper for the Social Science Research Network on theat topic.   The adviser for Ronald Reagan asserts that some people tie their perspectives too tightly to Fox News.  From on interview on CNN:
Lifelong conservative Bruce Bartlet

Many conservatives now refuse to even listen to any news or opinion not vetted through Fox, and to believe whatever appears on it as the gospel truth.

Not taking in multiple sources and perspectives on any portion of reality that you did not witness yourself can be disastrous, especially when one takes in information in order to determine one’s own actions.

This seems obvious.  There are indeed both right-wing and left-wing echo chambers yet the right-wing echo chamber was deliberately constructed as a commercial reaction to the bulk of the news media trending left-wing.

That’s correct: I asserted that the right-wing media came about to make money from a Republican and conservative audience, not as an ideological counterpoint or to elect a certain kind of candidate to public office.  For my purposes right now I condemn the people on my own side, but in principle the same problem holds true for Democrats.

Many conservatives live in a bubble where they watch only Fox News on television, they listen only to conservative talk radio — Rush Limbaugh, Sean Hannity, many of the same people… And so, they are completely in a universe in which they are hearing the same exact ideas, the same arguments, the same limited amount of data repeated over and over and over again. And that’s brainwashing.

This certainly creates a problem when there may be an actual reason something occurred that runs contrary to the orthodoxy promoted by, for example, Mark Levin.
