In this polarized age, have citizens retreated into information cocoons of like-minded media sources?
A new Pew Research Center report found that the outlets people name as their main sources of information about news and politics are strongly correlated with their political views. Almost half of all respondents that Pew classified as consistent conservatives named Fox News as their primary news source, while consistent liberals were disproportionately likely to name National Public Radio (13 percent), MSNBC (12 percent) and The New York Times (10 percent). These results are in line with studies suggesting that people tend to select news and information that is consistent with their political preferences in controlled settings.
