In my experience, many people believe that New Yorkers are smarter than other Americans, and this may actually be true. ... New Yorkers are people who left another place and came here, looking for something, which suggests that the population is preselected for higher energy and ambition.
I think it's possible that New Yorkers just appear smarter, because they make less separation between private and public life. That is, they act on the street as they do in private. In the United States today, public behavior is ruled by a kind of compulsory cheer that people probably picked up from television and advertising and that coats their transactions in a smooth, shiny glaze, making them seem empty-headed. New Yorkers have not yet gotten the knack of this. That may be because so many of them grew up outside the United States, and also because they live so much of their lives in public, eating their lunches in parks, riding to work in subways. It's hard to keep up the smiley face for that many hours a day.
