Separating fact from fiction is one of the most important tasks we have as citizens. Sure, there’s the high-minded political philosophy that we must seek truth to be whole, but I’m just talking about practical terms. Frankly, if we don’t know what is actually happening day to day in our lives and in the world around us, we’re going to make some really bad decisions. Maybe it’s deciding that we can perform field operations because we’ve watched a lot of Grey’s Anatomy. Maybe it’s deciding that we should try driving stunts because it looked super cool in the most recent Fast and Furious. Or maybe it’s sending thousands of servicemembers to distant lands to die.
Fake news isn’t dangerous because we disagree with it; it’s dangerous because it changes our reactions. It keeps us from seeing problems we need to fix, and turns things that are harmless into urgent issues. Indulge in fake news, and suddenly we’re tilting at windmills and ignoring bandits and thieves.
