Last week, Megan McArdle looked at
the Hindenburg-crashing-into-the-Titanic-during-a-volcanic-eruption how so many people’s assessment of the US general election is so at variance with reality:
Call it “the big sort” or “demographic clusters” or whatever you like, it all comes down to the same thing: Even as Americans talk more and more about diversity, they are increasingly dividing themselves into like-minded bubbles where other people, with other experiences and viewpoints, almost never penetrate. This is the message of books by Charles Murray and Robert Frank, and indeed of our own social media feeds.
All of those articles on “how to talk to your family about politics this Thanksgiving” might as well be called “how to discuss politics on the one day a year when you find yourself in a group that has not been hand-curated to remove dissenting viewpoints.”
I don’t exclude myself from this. I live in one of the most rarefied bubbles on the planet, a community of policy-focused knowledge workers in which I practically qualify as a proletarian because I have spent years in jobs that did not involve writing about what other people have done or ought to do.
Even the socialists here in Washington are often notable for their lack of personal familiarity with their side in the class war. Outside of family circles, I almost never meet anyone who does not have a college degree and a 401(k), unless I’m buying something from them, or giving a talk at a university to people who are on their way to having a college degree and a 401(k).
Social media, of course, makes this problem worse. Even if we are not deliberately blocking people who disagree with us, Facebook curates our feeds so that we get more of the stuff we “like.” What do we “like”? People and posts that agree with us. Given that Facebook seems to be the top news source for millennials, and an increasingly important one even for folks who grew up skimming dead trees for information, that matters quite a lot.
