Yes, they do talk differently, and duplicitously:
…here’s another way to look at the results. Liberals talk about politics in language that appeals to our primal socialist instincts, developed on the savanna when we belonged to small clans of hunter-gatherers who really did look out for their kin. Conservatives discuss politics in language that reflects modern reality: socialism doesn’t work in groups larger than a clan, because people do not behave selflessly when they belong to a large group of unrelated strangers. Liberals believe in what the economist Daniel Klein calls “The People’s Romance,” but that fallacy has been exposed by Adam Smith, de Toqueville and Darth Vader, among others.
When liberals say that “government is the word we give to the things we choose to do together,” they score high on affiliation, and some of them may even believe government is one big happy collaboration among equals. But conservatives know that philosophy just means giving one small group of people in the capital more power to boss and coerce the rest of us.
Yes. I think this also related to Jonathan Haidt’s thesis.
