Consume media outside one's bubble?

That “reality bubbles” contribute heavily to increasing political polarization is well-known. Customized media diets at scale and social media feeds that are tailored to individual proclivities progressively narrow our understanding of perspectives other than our own.

A non-trivial proportion of the population regards the media as having a responsibility to represent all idea with equal validity. So the appearance of extremist ideas in the press, even if they are treated negatively, results in more legitimacy than they are due. The authors in this essay make a case for quarantining these extreme ideas, refusing to cover them.
