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.
By the way, hope you are not trying to do branding by discussing it internally only. None of you are typical minds, so you may want to collect top 10 or top 100 best names and run it by your target audience, see what their impression is. Beta-test it, so to speak. (This forum barely counts as alpha-testing.)
