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.
On the other hand, "Bayes" could make people say: "It is about some advanced statistics, that's not for me."
I guess the goal is to provide rationality to everyone who cares, not to appear like something for-specialists-only.
I'm not sure that "Bayes" or "Bayesian" has a strong public association with anything unless you're already interested in statistics. I've used it in several discussions and every time had to give a quick explanation of what it meant. (Good practice for honing my explanations and reinforcing the concept in my own brain, as well.)
