The final straw was noticing a comment referring to "the most recent survey I know of" and realizing it was from May 2009. I think it is well past time for another survey, so here is one now.
I've tried to keep the structure of the last survey intact so it will be easy to compare results and see changes over time, but there were a few problems with the last survey that required changes, and a few questions from the last survey that just didn't apply as much anymore (how many people have strong feelings on Three Worlds Collide these days?)
Please try to give serious answers that are easy to process by computer (see the introduction). And please let me know as soon as possible if there are any security problems (people other than me who can access the data) or any absolutely awful questions.
I will probably run the survey for about a month unless new people stop responding well before that. Like the last survey, I'll try to calculate some results myself and release the raw data (minus the people who want to keep theirs private) for anyone else who wants to examine it.
Like the last survey, if you take it and post that you took it here, I will upvote you, and I hope other people will upvote you too.
If I expect that my estimate will change in the future, why not change it now? I grant that it is highly likely that my estimates will change, but I don't know whether any particular estimate will change upward or downward, so for now they stay put.
I suppose what anticipation of change in a probability estimate practically means is that you expect new pieces of evidence to come in and that you have a fairly good idea what the magnitude of evidence will be, just not the sign.
I don't know which direction it will change, but for things I'm unsure of I expect more movement than for things I know more about. In bayesian terms, a weak prior.
