Nate Silver, the statistician who correctly predicted the 2012 electoral results, wrote an interesting and insightful piece entitled, “There Really Was a Liberal Media Bubble,” at his website FiveThirtyEight. As the headline suggests, the topic was the liberal media bias in the 2016 election cycle. Silver pointed out, among several, how groupthink affected the media’s incorrect predictions:
Diversity of opinion? For starters, American newsrooms are not very diverse along racial or gender lines, and it’s not clear the situation is improving much.6 And in a country where educational attainment is an increasingly important predictor of cultural and political behavior, some 92 percent of journalists have college degrees. A degree didn’t used to be a de factoprerequisite7 for a reporting job; just 70 percent of journalists had college degrees in 1982 and only 58 percent did in 1971.
The political diversity of journalists is not very strong, either. As of 2013, only 7 percent of them identified as Republicans (although only 28 percent called themselves Democrats with the majority saying they were independents). And although it’s not a perfect approximation — in most newsrooms, the people who issue endorsements are not the same as the ones who do reporting — there’s reason to think that the industry was particularly out of sync with Trump. Of the major newspapers that endorsed either Clinton or Trump, only 3 percent (2 of 59) endorsed Trump. By comparison, 46 percent of newspapers to endorse either Barack Obama or Mitt Romney endorsed Romney in 2012. Furthermore, as the media has become less representative of right-of-center views — and as conservatives have rebelled against the political establishment — there’s been an increasing and perhaps self-reinforcing cleavage between conservative news and opinion outlets such as Breitbart and the rest of the media.
