You can't just start from the assumption that society would be more rational if rationality was taught at school. You'd also need evidence that rationality can be taught to a lot of average people. I don't think such evidence exists. Whatever taken out from the curriculum might be replaced by something completely ineffective.
Can't specific rationality techniques be effectively taught to a large amount of average people, though? I vaguely recall that there might be some examples of that in studies where the researchers taught participants a trick or two before submitting them a test of some sort, but my ability to recall specific examples is almost geometrically inverse to gwern's, so that certainly takes out of my point.

I know of no evidence that this is possible -- where "effectively" means "after several years still actively using these techniques in their lives".
Does anyone know of a good article that illustrates how society is generally irrational, and how making society more rational would have huge benefits, because it'd be a very high level action?
I'm writing an essay about how to improve education, and one of my proposals is that a core part of the curriculum should be rationality. I believe that doing this would have huge benefits to society, and want to explain why I think this, but I'm having trouble. Any thoughts?
Edit: Part of Raising the Sanity Waterline talks about common ways in which people are irrational. However, they're all links to longer Less Wrong articles. Preferably, I'd like to illustrate it in a few sentences/paragraphs.
