I think it’s mostly a result of the huge increase in the availability of news and information exacerbated by some particularly polarizing events. Over the course of the last couple of decades, we’ve gone from a point where even the people most interested in news probably only got new information once a day, to the point where people who previously couldn’t have cared less, hear way more about it within hours, sometimes even minutes, of events happening. So, by being bombarded with information, it’s difficult not to have at least some sort of opinion on it and by our very nature, we tend to build into an us vs. them mentality, and once that opinion starts to take hold, confirmation bias just strengthens it.
So, let’s take politics as an example. In the 90s, there were still Republicans and Democrats, but there was a huge number of people in the middle who were, for better or worse, pretty much ill-informed on the issues simply because they weren’t incentivized to go read up about whatever random events that might sway their opinion one way or the other. But these days, even if one doesn’t particularly care, they’re going to hear about the latest thing that Obama, Boehner, or whoever did, whether it’s through the 24-hour news cycle on Cable, Facebook, Twitter, or whatever other social media they use. Thus, by simply hearing about it, even if they don’t care, it will have to have some sort of affect, and then it just slides more and more in one direction or the other.
All of this increase in social media just happens to occur while we have some news going on that is inherently polarizing. Regardless of what your opinion was on the Iraq war under Bush, I think it’s hard to look at the news and information circulating about it and still not have some opinion about whether it was good or bad. Wars have a way of being highly polarizing by their nature, and this happens while our society is adjusting to this huge influx of new information and trying to figure out how to filter out the trash and form opinions with it. And so, I think people who weren’t used to getting all that sort of information got information overload, started forming opinions on it even if they previously wouldn’t have cared much, and then pretty much just ran with it.
And now that we’re heavily polarized, where before people who were somewhere in between could be comfortable there since they had a lot of company, they just get fewer and fewer, feeling the social pressure to join a team because everyone else has, and then getting the pressure itself from their family, friends, and coworkers.
That all said, it does seem like there’s a bit of a trend where whole new ideas come out that don’t have a strong correlation with established teams, so to speak, and now that we’ve started to learn to filter out the extraneous information, people are starting to be able to make a bit more informed decisions. It’s particularly interesting to see how some recent things have drawn some Dems and Pubs with a lot more similar representation on both sides than in the past. I wonder if this trend is strong enough to, in time, overcome the tides of polarization, or if polarization will set too strongly and we’ll see these new ideas start with that sort of evenness but ultimately settle out such that it will end up associated with one side or the other and slowly slip back that way. I really hope it’s the former.
