Okay. This may not be the kind of thing you had in mind, but the way I personally think about things:
is probably not focused enough on emotions. I'm not very good at dealing with emotions, either myself or other people's, and I imagine that someone who was better would have very different thoughts about how to deal with people both on the small scale (e.g. interpersonal relationships) and on the large scale (e.g. politics).
may overestimate the value of individuals (e.g. in their capacity to affect the world) relative to organizations.
The way this community thinks about things:
is biased too strongly in directions that Eliezer finds interesting, which I suppose is somewhat unavoidable but unfortunate in a few respects. For example, Eliezer doesn't seem to think that computational complexity is relevant to friendly AI and I think this is a strong claim.
is biased towards epistemic rationality when I think it should be more focused on instrumental rationality. This is a corollary of the first bullet point: most of the Sequences are about epistemic rationality.
is biased towards what I'll call "cool ideas," e.g. cryonics or the many-worlds interpretation of quantum mechanics. I've been meaning to write a post about this.
is hampered by a lack of demographic diversity that is probably bad for cognitive diversity (my impression is that LW is overwhelmingly male, white, 18-24 years old, etc.).
Atheism and skepticism in general:
It takes incredible strength to recognize flaws in your entire way of thinking
Eh, does it? I think it just requires a cultural meme about criticism being a good thing. LW has this, maybe too much of this, and my impression is that so does Judaism (based on e.g. avoiding your belief's real weak points). This is some evidence that you are thinking reasonably but it isn't extremely strong evidence.
For example, Eliezer doesn't seem to think that computational complexity is relevant to friendly AI
Could you elaborate?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
