Well, the bit about platonism may be. Tegmark, I believe, came up with a notion along the lines of "well, if all mathematical structures are in some sense 'real', then we just need to somehow parameterize the set of all mathematical structures that could contain beings 'like us', then compare our observed universe to the 'most average' structures. If we differ significant'y from that, it's evidence against the proposition."
What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
