Having "Rationality" in the name would probably be a bad thing. (Straw Vulcan stereotypes and all that.) "Bayesian" is a much better choice IMO.
Why not call it something like BayesWay?
Or how about that old Japanese cliche... "Better than Yesterday"? That would go well with Stabilizer's "Update Yourself" byline.
Upvoted for "Better than Yesterday."
The Singularity Institute wants to spin off a separate rationality-related organization. (If it's not obvious what this would do, it would e.g. develop things like the rationality katas as material for local meetups, high schools and colleges, bootcamps and seminars, have an annual conference and sessions in different cities and so on and so on.)
We can't think of a name for this organization.
We can't think of any names that seem good enough to be audience-tested.
We don't have any ideas good enough that we'd want to mention them in this post.
Help.
