Regarding the article, this is a very interesting study, and it actually isn't very surprising once I think about it. I've always sort of got the sense that there's a fundamental difference between how people of different political persuasions approach issues. If that wasn't the case, and if there was no such fundamental difference, people would eventually be able to agree on an issue with enough debate.
