He went on the argue that this correlates with libertarianism. That political ideologies aren't just differences of opinion, but fundamentally different approaches to thinking about problems and organizing systems.

I see an article every six months or so claiming something like this, though the libertarian angle is a new twist -- the usual claim is that conservatism implies an authoritarian personality. Every time I've bothered to look into one in any depth the data has turned out to be exceptionally weak, or confounded in grossly, painfully obvious ways (e.g. by failing to control for age or income).

This is flattering to a different demographic, but I'm no less skeptical.
