There is an infectious agent (I forget whether it’s a virus or a bacterium) that causes ants to crawl out to the tips of grass leaves. This change in the ant’s behavior is of no value to the ant — the value is to the infectious agent. A cow eats the grass and ingests the ant. The virus (we’ll say it’s a virus) needs to be in the digestive tract of a cow in order to reproduce.
There’s another virus that causes rodents to become fearless around cats. Same deal. The infection results in the death of the rodent, who is now behaving in an irrational manner, charging around in front of the cat instead of running. The behavior is, however, advantageous to the virus, which needs to be in the digestive tract of the cat in order to reproduce.
These examples explain a great deal about the current political environment in the United States.
I’ve been reading about memes. The idea is, a meme is not a physical thing like a virus, but it can act in an analogous way. A meme is a pattern of mental behavior, and the pattern can either reproduce successfully by spreading through a human culture, or it can die out. Patterns of behavior that are well suited to the human brain tend to spread. Those patterns are called memes.
The behavior, in many cases, is verbal behavior. An idea that lodges successfully in your brain and urges you to speak (or write) that idea so that your fellow humans can ingest it is going to survive. That’s how the meme reproduces. It’s evolution in action.
A meme that causes your brain to bypass the fact-checking process has an advantage. It’s more likely to survive, because it’s streamlined. Fact-checking is not only expensive biologically (in terms of brain effort), fact-checking can also kill bad memes. So if the meme can bypass fact-checking by appealing to your emotions, it’s more likely to survive.
This is how the idea of “God” has become so pervasive. It appeals to our emotions. The “God” idea has to bypass fact-checking in order to survive, because fact-checking would kill it.
Many conservative ideas survive in exactly the same way: Fact-checking would kill them. Racial bigotry, for example (a very popular meme among conservatives), appeals to our fear of the stranger. Someone who is Not Like Me And My Friends is a source of fear. The meme — the idea that other races are inferior to mine — hijacks that fear and uses it to reproduce itself, spreading through a population.
This morning I got into one of those pointless Facebook wrangles with a fellow who insisted on thinking that there’s a debate about global warming. There isn’t, not really. The details are still somewhat unsettled, but the facts are clear. The polar ice caps are melting (fact). Carbon dioxide is a greenhouse gas (fact). Human activity produces an enormous excess of carbon dioxide (fact). Therefore, humans are causing global warming. Them’s the facts.
What seems to happen is the the meme “global warming is a hoax” has hijacked the emotional mechanism that says, “I’m just as smart as anybody else.” And also, “My friend says this, and I trust my friend.” Those are simple, emotionally appealing ideas. The meme uses those emotions to spread itself. In the absence of those emotions, fact-checking would be a lot more likely to kick in. Fact-checking would destroy the meme.
I feel sorry for people whose brains have been hijacked by bad memes. Also, those people scare me, because they’re dangerous. They’re in the grip of these mentally transmitted infectious ideas, and they’re quite likely to destroy all that’s good in our shared future.
They’re rodents dancing fearlessly in front of the cats. And they don’t know why they’re doing it. Memes are mind control agents. Check yourself.
