Pollster Nate Silver wrote a series of analysis on the polling and data pertaining the recent election.  The most recent is There Really Was A Liberal Media Bubble:

The share of total exposure8 for the top five news sources9 climbed from roughly 25 percent a decade ago to around 35 percent last year, and has spiked to above 40 percent so far in 2017. While not a perfect measure10, this is one sign the digital age hasn’t necessarily democratized the news media. Instead, the most notable difference in Memeorandum sources between 2007 and 2017 is the decline of independent blogs; many of the most popular ones from the late ’aughts either folded or (like FiveThirtyEight) were bought by larger news organizations. Thus, blogs and local newspapers — two of the better checks on Northeast Corridor conventional wisdom run amok — have both had less of a say in the conversation.

All things considered, then, the conditions of political journalism are poor for crowd wisdom and ripe for groupthink. So … what to do about it, then?

Initiatives to increase decentralization would help, although they won’t necessarily be easy. Increased subscription revenues at newspapers such as The New York Times and The Washington Post is an encouraging sign for journalism, but a revival of local and regional newspapers — or a more sustainable business model for independent blogs — would do more to reduce groupthink in the industry.

That leaves independence. In some ways the best hope for a short-term fix might come from an attitudinal adjustment: Journalists should recalibrate themselves to be more skeptical of the consensus of their peers. That’s because a position that seems to have deep backing from the evidence may really just be a reflection from the echo chamber. You should be looking toward how much evidence there is for a particular position as opposed to how many people hold that position: Having 20 independent pieces of evidence that mostly point in the same direction might indeed reflect a powerful consensus, while having 20 like-minded people citing the same warmed-over evidence is much less powerful. Obviously this can be taken too far and in most fields, it’s foolish (and annoying) to constantly doubt the market or consensus view. But in a case like politics where the conventional wisdom can congeal so quickly — and yet has so often been wrong — a certain amount of contrarianism can go a long way.

An excellent read, and I encourage reading the other pieces he wrote analyzing the election.  This innate bias is more important than accuracy in forecasting elections; it is also key to the lack of confidence and respect of the larger media.
