As promised, here is the "Q" part of the Less Wrong Video Q&A with Eliezer Yudkowsky.
The Rules
1) One question per comment (to allow voting to carry more information about people's preferences).
2) Try to be as clear and concise as possible. If your question can't be condensed to a few paragraphs, you should probably ask in a separate post. Make sure you have an actual question somewhere in there (you can bold it to make it easier to scan).
3) Eliezer hasn't been subpoenaed. He will simply ignore the questions he doesn't want to answer, even if they somehow received 3^^^3 votes.
4) If you reference certain things that are online in your question, provide a link.
5) This thread will be open to questions and votes for at least 7 days. After that, it is up to Eliezer to decide when the best time to film his answers will be. [Update: Today, November 18, marks the 7th day since this thread was posted. If you haven't already done so, now would be a good time to review the questions and vote for your favorites.]
Suggestions
Don't limit yourself to things that have been mentioned on OB/LW. I expect that this will be the majority of questions, but you shouldn't feel limited to these topics. I've always found that a wide variety of topics makes a Q&A more interesting. If you're uncertain, ask anyway and let the voting sort out the wheat from the chaff.
It's okay to attempt humor (but good luck, it's a tough crowd).
If a discussion breaks out about a question (f.ex. to ask for clarifications) and the original poster decides to modify the question, the top level comment should be updated with the modified question (make it easy to find your question, don't have the latest version buried in a long thread).
Update: Eliezer's video answers to 30 questions from this thread can be found here.
I guess my main answers would be, in order:
1) You'll have to do with the base probability of a highly intelligent human being a sociopath.
2) Elaborately deceptive sociopaths would probably fake something other than our own nerdery...? Even taking into account the whole "But that's what we want you to think" thing.
3) All sorts of nasty things we could be doing and could probably get away with doing if we had exclusively sociopath core personnel, at least some of which would leave visible outside traces while still being the sort of thing we could manage to excuse away by talking fast enough.
4) Why are you asking me that? Shouldn't you be asking, like, anyone else?
Re. 4, not for the way I asked the question. Obviously asking for a probability, or any empirical evidence I would have to take your word on, would have been silly. But there might have been excellent public evidence against the Evil hypothesis I just wasn't aware of (I couldn't think of any likely candidates, but that might have been a failure of my imagination); in that case, you would likely be aware of such evidence, and would have a significant icentive to present it. It was a long shot.
