In school they taught that the climate in Mexico led to large sugar plantations while the climate of the US led to smaller farms especially in the north. Then this led to a more egalitarian distribution of wealth in the northern US which created the middle class demand that allowed manufacturing to take off. In Mexico the poor were too poor to buy a lot of these manufactured goods while the rich plantation owners could afford superior goods.
I'm not sure how an intelligence based explanation would explain this better.
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.
