Why False Ideas Persist
There is another reason bad ideas continue to live on, which is that people continue to talk about them.
Silence is death for any idea. An idea that is never spoken or written down dies with the person who conceived it. Ideas can only be remembered when they are repeated. They can only be believed when they are repeated.
I have already pointed out that people repeat ideas to signal they are part of the same social group. But here's a crucial point most people miss:
People also repeat bad ideas when they complain about them. Before you can criticize an idea, you have to reference that idea. You end up repeating the ideas you’re hoping people will forget—but, of course, people can’t forget them because you keep talking about them. The more you repeat a bad idea, the more likely people are to believe it.
Let's call this phenomenon Clear's Law of Recurrence: The number of people who believe an idea is directly proportional to the number of times it has been repeated during the last year—even if the idea is False.
Each time you attack a bad idea, you are feeding the very monster you are trying to destroy. As one Twitter employee wrote, “Every time you retweet or quote tweet someone you’re angry with, it helps them. It disseminates their BS. Hell for the ideas you deplore is silence. Have the discipline to give it to them.”
Your time is better spent championing good ideas than tearing down bad ones. Don't waste time explaining why bad ideas are bad. You are simply fanning the flame of ignorance and stupidity.
The best thing that can happen to a bad idea is that it is forgotten. The best thing that can happen to a good idea is that it is shared. It makes me think of Tyler Cowen's quote, “Spend as little time as possible talking about how other people are wrong.”
Feed the good ideas and let bad ideas die of starvation.
