The US has had, in its history, a large-scale immigration from just about every region of the world, and most of them have interbred. The result is a population with lots of outbreeding depression and heterosis, leading to a much wider variation in intelligence and other abilities than anywhere in the world. The ultimate outcome of that is a lower average intelligence in the US than in other countries, due to outbreeding depression, counterbalanced by a small number of exceptional people, who got lucky and benefited from heterosis.
Interesting idea. This suddenly makes me take my gf's remark about how "mismatched" and "weird" average American faces tend to look a bit more seriously.
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.
