Waiting in line at Tokyo immigration control, I met a woman from North Carolina who’d come to Japan for an organized tour of Japanese baseball parks (17 of them). She learned about the tour from a friend. In America, she’s visited 117.
I told her I was a psychology professor and had a theory of evolution in which connoisseurship played a big role. She was a baseball-park connoisseur, I said.
The evolutionary role of connoisseurs and collectors was to provide demand for finely-made stuff — things made by state-of-their-art artisans. Connoisseurs and collectors would pay more for features that had no clear value otherwise. By trading for these things, the connoisseurs and collectors helped the artisans make a living and thereby push their technology further.
