This is a good comment, thanks. I have one thing I would like to highlight: > people made up theories of why New Yorkers were more psychotic than Londoners (this is somewhere in "Listening to Prozac"). Maybe I need to read your source for more context. But I could see this being a very alluring theory in prior decades, before New York and urban areas in general started seeing massive crime drops, gentrification, etc. In the 70s and 80s many talked about New York as an ugly place, somewhere to escape from. It's pretty different now. Then I wonder about some other uniquely American problems, like the extent of our gun violence, or poor health care. And I wonder what people may say about mental illness rates compared to other developed counties. (Surely someone has looked.)
