admitting you're wrong = winning/learning
conservation of expected evidence (add formula)
The path to truth is a random walk
discussions are random walks
what is true is already so
rationality: outcomes > rituals of thought
what can be destroyed by truth, should be
update beliefs incrementally
beliefs should pay rent
the cat 's alive, curiosity got framed
optimize everything
delta knowledge = surprise
minimize future surprise

Thank you, these are some great ideas. For the broad audience, I think "What Is True Is Already So" and something about yay for changing your mind would work especially well.
As part of my broader project of promoting rationality widely, I'm going to work on making rationality-themed merchandise with slogans. I'd appreciate any ideas on what slogans would be short (5 words or less), engaging, and accessible, and appealing for both aspiring rationalists and smart youth and young adults who are just starting to learn about rationality. As an example, slogans like "Growing Mentally Stronger" or "Updating My Beliefs" are good, but "Tsuyoku Naritai!" is not, however much I personally like that slogan.
