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.
Can't assume google/facebook/twitter were successful because of a master plan that hinged on their name; their success doesn't strongly imply they were named well. Anecdotally, facebook was originally "The Facebook", google was originally "Googol", Twitter was once "twttr", and Apple was named on a whim when nothing could be decided on.
Bayesian is an alien word, I still remember wondering what it was when I first saw it. Repeating a word/name aloud is the recommended way to remember them on first impression, and memorability matters, but encouraging that kind of memorability is a small factor anyway, just for the record.
Edit: Whether or not my ideas are good, I disagree that the importance of immediate reaction is overrated. It's hard to say precisely how it has been "rated" in the conversation, but I think it matters a lot in framing the ensuing seconds of conversation.
