I wouldn’t expect an intelligent conservative to posit it either. That was the largest part of my shock; not that intelligent people were conservative, but that people I thought intelligent were spouting views that I correlated more closely with “Get your government hands off my Medicare.” than with any thoughtful conservative analysis.
That encounter (among others) has changed my beliefs about the beliefs of others, and I do talk to many people of differing views. My most strongly held belief that was shaken, though, was the belief that intelligent people who disagree can at least find sufficient common factual ground to determine the precise nature of their disagreement, if not to come to consensus. Belief-as-attire is the best explanation I’ve seen for that, but it doesn’t help me much in interacting with such believers, since by the time I’ve determined their beliefs they have determined mine, and identified me as an outsider.
I think you’re right, but suspect I will have more difficulty with the first than with the second. I am honestly curious about almost everything, which is a decent stand-in for spinning lack of knowledge as a personal deficit, but I am very bad at not speaking. I work at it, but I remain someone whose default setting is to babble at random people on the street. I’m better at “tactfully noncommittal” than I used to be, but I’m still pretty bad at it.
