According to the article, cable news is more likely to divide people on political issues than social media or online news. An interesting thing I learned was that about 17% of Americans were politically polarized because they watched TV news, which was three to four times as many as those who read news online. The researchers also found that cable news viewers tend to stick with sources that match their political opinions. This implies that social media is not always the primary source of political echo chambers, and that traditional media may have an even greater influence.
