I think it probably works as well as other dichotomies, such as extrovert/introvert feeling/thinking or the other Myers Briggs categories. [/quote]
I don’t agree with that because, taking introvert vs extrovert for example, it’s just a linear spectrum between two extremes regarding one issue.
“Conservative” vs. “liberal” means a million different things, depending on what issue you are talking about… that’s why it’s useless to argue based on “teams” as seems to be peoples’ general tendency. Each issue should be debated on its own merits, not what two (just two, for a million issues!!) teams think about it.
I think the Scientific American article is cool and the thing about innate tendencies sure seems plausible. But I do not agree that “liberal” vs “conservative” is anything like a single topic, linear spectrum such as “introvert” vs. “extrovert.”
