I thought some NORC researchers did teach in the College. At one of my kids’ Class Days (or whatever they call it), the speaker in the favorite-faculty-member slot was a guy whose main gig was at NORC but who taught some wildly popular Econ class. He had a deadly, dry wit – fun to listen to, very classy. He was definitely an economist, even allowing for some of the blurred lines between economics and other social sciences at Chicago and everywhere else these days, and he was someone lots of kids in the room obviously knew.
Yes, there are undergraduates working at NORC doing a variety of social-science type stuff. I don’t know if they are “interns” or just working part-time research-assistant gigs.
