Well, if your justifications are truly marvelous but the margin of this post is too narrow to contain them, you are basically asking everyone to trust you that you know what you're talking about. This makes it an argument by reputation (or, in a slightly more pronounced form, an argument by authority).
I am fairly confident that you have justifications you haven't bothered stating. But that's not the question, the question is whether they are good justifications and this is a much more complicated matter.
You don't seem to be engaging with what I said in the grandparent at all. The claim was:
We benefit greatly by not having a norm of only stating conclusions that are a small inferential distance away from public knowledge
Maybe you disagree with this, but you don't even explicitly state disagreement; your comment just looks like an attempt to enforce the very norm that I claimed was undesirable.
I feel that a lot of what's in LW (written by Eliezer or others) should be in mainstream academia. Not necessarily the most controversial views (the insistence on the MW hypothesis, cryonics, the FAI ...), but a lot of the work on overcoming biases should be there, be criticized there and be improved there.
For example, a few debiasing methods and a more formal explanation of LW's peculiar solution to free will (and more, these are only examples).
I don't really get why LW's content isn't in mainstream academia to be honest.
I get that peer review is not the best (far from it, although it's still the best we have, and post-publication peer-review is also improving, see PubPeer), that some would too readily dismiss LW's content, but not all. Lots would play by the rules and provide genuine criticisms during peer-review (which will lead to the alteration of the content of course), along with criticisms post publication. This is in my opinion something that has to happen.
LW, Eliezer, etc, can't stay on the "crank" level, not playing by the rules, publishing books and no papers. Blogs are indeed faster and reach a bigger amount of people, but I'm not arguing for only publishing in academia. Blogs can (and should) continue.
Tell me what you think, as I seem to have missed something with this topic.
