Something to keep in mind when you’ve got something in mind you want to get people to change their minds about:
Inadvertently, he’d opened up a debate with his own investors, which he counted among his least favorite ideas. “I hated discussing ideas with investors,” he said, “because I then become a Defender of the Idea, and that influences your thought process.” Once you became an idea’s defender you had a harder time changing your mind about it.”
That’s from The Big Short by Michael Lewis. The person talking is the genius hedge fund manager at the center of the book who foresaw the housing bubble bursting two years ahead---and prepared to make a killing off it, but never mind that. Point is that it’s a good idea to keep a distance between yourself and your own good ideas in case you need to be able to decide they’re no good. Going to pass it along to my students. It relates to something I warn them about. People’s sense of self gets tied up in their opinions and ideas being right and giving them up and admitting those opinions and ideas are wrong feels like giving up a piece of themselves and admitting they are wrong in being themselves. I’m not sure they get that I’m warning to them to watch out for this in themselves and not just in people they’re arguing with.
