It’s called the Dunning-Kruger effect. In a nutshell, stupid people are too stupid to realize they are stupid. Smart people can see how complex and confusing the universe really is, they know that they can’t know everything.
So, when arguing politics, stupid people argue with absolute conviction. They have no doubt in their minds that they are right. Big government is evil, but war is necessary because America must be strong. Anyone who is anti-war must be unpatriotic. Being unpatriotic is bad. Liberals are against war, and for big government. Liberals are unpatriotic.
And try as you might, you just cannot convince them they are wrong. Because they are too stupid to understand that they don’t understand. They think Rush Limbaugh and Glen Beck are smart. They think Sarah Palin is smart. Anybody smarter than that just can’t be trusted.
I’m not sure what the solution to this dilemma is. Stupid people vote. It wouldn’t be fair to deny them the right to vote. After all, stupid as they are, they’ve got just as much stake in the future of the planet and human civilization as smart people do. And they vote in droves because they are sure they understand the situation and they are sure they are right. They know for a fact that lower taxes on the rich will create jobs, even though they never do. They knew for sure that Iraq had weapons of mass destruction, and some of them still believe it. They know for sure that global warming is a hoax. Forget all those smarty pants scientists. They know that Republicans are the party of family values and no amount of scandals with underaged boys, prostitutes or boy prostitutes will convince them otherwise.
I guess that writers just have to keep on writing, scientists keep on discovering and inventors keep on inventing. Because as far as politics are concerned, we are screwed.
