I don't think this qualifies as a belief; it's just something I have noticed.
My dreams are always a collection of images (assembled into a narrative, naturally) of things I thought about precisely once the prior day. Anything I did not think about, or thought about more than a single time, is not included. I like to use this to my advantage to avoid nightmares, but I have also never had a sex dream. The fact that other people seem to have sex dreams is good evidence that my experience is rare or unique, but I have no explanation for it.
My nightmares are some of my most interesting dreams, so I don't try to avoid them.
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.
