Acknowledging that it is a big city, and “high trust“ is a vague concept:
I strongly disagree with the characterization that New York City is “the furthest thing from high trust I can think of“
I have interacted with thousands of strangers there with near perfect shared understanding of basic city etiquette. That etiquette does not include warmth, and in fact the way that we have all learned it is someone being quite rude to us when we break the etiquette, but that the city functions at all suggests they are doing something right.
