And what you optimise for should depend on what you’re writing. Sometimes I primarily optimise for A) making readers have true beliefs about what I believe. Other times I primarily optimise for B) providing readers with tools that help them come to their own conclusions.
When I’m doing B, it doesn’t matter what they believe I believe. If out of ten things I say, nine will be plain wrong, but one thing will be so right that it helps the reader do something amazing with their lives, I consider that a solid success.
