We began this chapter by asking what the job of keeping the republic is if we're locked in separate media bubbles, and creating narratives that fit our preconceived ideas rather than challenging us to think critically.
The official rules of the Electoral College gave the presidency to Donald Trump even though Hillary Clinton won the popular vote.
It is tempting to say that living in a closed information bubble brings us very close to losing the common understanding and shared beliefs that make a peaceful resolution of our differences possible.
The best example might be a fundamental one.
"Make America Great Again" was the slogan of Donald Trump's campaign.
He explained that the slogan stood for Immigration was destroying the country, trade had stolen our jobs, Muslims threatened our security, the military was terrible, and we were a loser of a country.
Only Trump could fix this mess of a nation.
It was a frightening vision.
The vision was alien to half the population.
It was a hit with Trump's supporters.
America was not great anymore.
There were too many people who looked different, too many people who didn't speak English, too many people who upending gender roles, and too many people who got fat off.
When they were white, working-class citizens, a lot of people looked down on them for being who they were.
Making America great again meant restoring their dignity, making them whole, and soothing the sense of grievance that convinced them the rules of life were rigged against them.
Clinton's supporters were in a different place.
The picture was good.
Many thought a barrier would never be broken when a popular African American president left office after two full terms.
People of color were positive about their futures.
There was power in the organization of Black Lives Matter, even though cops were still killing black men.
Many people thought a woman might win the presidency.
It meant interesting people, great restaurants, and a colorful world.
People could smoke pot in a few states, gays were free to marry, and trans people were free to be themselves.
With a Democrat in the White House for four more years, many of the changes that Obama had enacted to protect the environment, provide security to immigrants, and provide health care to all would be locked in, and liberals on the Supreme Court would secure reproductive rights for women.
It seemed that America could only get better.
The election was the great equalizer.
With Trump on his way to the White House, the optimistic, rose-colored-glasses people began to feel that maybe they did, in fact, live in an apocalyptic world.
Things began to look better for the Trump supporters.
Whether the two narratives would meet somewhere in the middle or on separate paths is an open question with consequences.
The stakes of living in separate narrative bubbles are critical to us all.

The "mainstream media" is an epithet for many conservatives.
Many on the left are fond of consuming their partisanship in the new media.
The journalism tradition of nonpartisan objectivity is a reminder that what is passing is not only a business but also a profession.
Journalists didn't always live up to that tradition.
They were shamed when their biases were exposed, but they generally accepted it.
Rules about facts and sources were part of the profession.
The profession of journalism has involved a spirit of public service and adventure-- reporting from a bomber during a raid in World War II, exposing the suffering of Sudan or Appalachia, or rushing to the site of the World Trade Center moments after the buildings fell.
The changes we see in the media are also a decline.
Since makeup for guests is cheaper than reporting, most cable news networks have forsaken objectivity.
There is an endless hunger to comment and little appetite for verification on most internet sites.
Few American Bloggers have the resources or inclination to report from war zones, famines or genocides in repressive countries.
