There is a new kind of ignorance afoot in the world, one that results from overconsumption of information rather than from a lack of access to it.
It's fashionable to blame cable television and the Internet for this new ignorance. And it's true that if you spend much time with these media, you'll come away thinking that many information providers are more interested in fanning fear and feeding people's preconceived notions than they are at communicating truth.
But we should really blame ourselves for the content we're seeing. Why? Because what shows up on the Internet and cable television is shaped by what we choose to click on and watch, and we're making terrible choices.
Our news is largely provided by conglomerates focused on the bottom line, and they have figured out that shrill opinions and celebrity hype draw more eyes than do facts and substance. Fear, opinion and gossip are less expensive to manufacture and draw bigger audiences than the truth.
Seeking, processing and communicating information is something humans are hard-wired to do, and that has been no less an evolutionary advantage than opposable thumbs. Forming communities and sharing intelligence in a network have been key to human survival and evolution over eons. But our brains didn't evolve the way they did in order to process bland facts and false conspiracies.
It's a lot like our food diets. They, too, have changed in the last half-century, and for much the same reason. We are hard-wired to crave salt, sugar and fat, all of which were hard to come by in earlier eras. But in this age of plenty, at least in developed nations, industrialized food suppliers have filled supermarket aisles with delicious but unhealthful concoctions aimed at satisfying those cravings. Why? Because we buy them.
In the case of information, we're wired to seek out and retain facts that are essential to our survival. Instead, we're loading up on false information, and that can trigger fear instincts unnecessarily.
In Washington, fear born of ignorance is often on display. Not long ago, there was the guy who stood in front of the White House with a sign reading "Keep Your Government Hands Off My Medicare," and another in front of the recently closed Walter Reed Army Medical Center whose sign read "Enlist Here to Die for Halliburton." Neither sentiment makes much sense, but both the protesters probably believed they were highly informed.
