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.
It seems like, if I'm trying to make up my mind about philosophical questions (like whether moral realism is true, or whether free will is an illusion) I should try to find out what professional philosophers think the answers to these questions are.
If I found out that 80% of professional philosophers who think about metaethical questions think that moral realism is true, and I happen to be an anti-realist, then I should be far less certain of my belief that anti-realism is true.
But surveys like this aren't done in philosophy (I don't think). Do you think that the results of surveys like this (if there were any) should be important to the person trying to make a decision about whether or not to believe in free will, or be an moral realist, or whatever?
My answer to this depends on what you mean by "professional philosophers who think about". You have to be aware that subfields have selection biases. For example, the percent of philosophers of religion who think God exists is much, much larger than the percent of professional philosophers generally who think God exists. This is because if God does not exist philosophy of religion ceases to be a productive area of research. Conversely, if you have an irrational attachment to the idea that God exists this than you are likely to spend an inordinate... (read more)
