I'm afraid that wasn't enough to clear it up for me. Nor is it clear how privileging the hypothesis is relevant to a discussion of logical possibility. Or are you claiming that was the wrong domain of inquiry?
Saying "X is logically possible" bears the conversational implication that X is worth considering - it raises X to conscious attention. But when we're talking about physical possibility, "logically possible" is the wrong criterion for raising hypotheses to conscious attention, because epistemological limitations imply that every hypothesis is logically possible. Given that we have good physical reasons to draw the opposite conclusion in this case, it is generally a mistake to emphasize the possibility.
Less Wrong is extremely intimidating to newcomers and as pointed out by Academian something that would help is a document in FAQ form intended for newcomers. Later we can decide how to best deliver that document to new Less Wrongers, but for now we can edit the existing (narrow) FAQ to make the site less scary and the standards more evident.
Go ahead and make bold edits to the FAQ wiki page or use this post to discuss possible FAQs and answers in agonizing detail.
