I assume that, despite the name, people here don't take consequentialism to imply strictly CDT. I still think that in the True Prisoner's Dilemma against a paperclip maximizer known to use the same decision algorithms as ourselves it's immoral to defect.
May the reason why so many philosophers don't vote for consquentialism is that they're thinking about pure CDTical act consequentialism?
Despite being (IMO) a philosophy blog, many Less Wrongers tend to disparage mainstream philosophy and emphasize the divergence between our beliefs and theirs. But, how different are we really? My intention with this post is to quantify this difference.
The questions I will post as comments to this article are from the 2009 PhilPapers Survey. If you answer "other" on any of the questions, then please reply to that comment in order to elaborate your answer. Later, I'll post another article comparing the answers I obtain from Less Wrongers with those given by the professional philosophers. This should give us some indication about the differences in belief between Less Wrong and mainstream philosophy.

Thanks pragmatist, for attaching short (mostly accurate) descriptions of the philosophical positions under the poll comments.
