House rules for reasoning
- Define your terms before you defend them.
- Say out loud what would change your mind.
- Attack the idea, never the person holding it.
- Keep what you know apart from what you merely suspect.
- Ask how common a thing is before you ask how scary it sounds.
- Plug the answer back into the problem.
- A good counterexample beats a long speech.
- Being wrong in public is how careful people get that way.
