Kind of stupid without a definition of ideological diversity. Cowen uses "ideological diversity" as a stand-in for Democratic/Republican balance. Which is one kind of diversity, and you would likely find the most balanced distribution of opinion on such questions as "is Mueller biased against Trump?" and "is Paul Ryan's tax plan good?" in the cities mentioned. But here's a couple other questions that are likely more balanced in e.g. San Francisco than the cities mentioned: Are microstate monarchies the ideal form of government? Did the Constitution establish white supremacy? Should Keystone XL be blocked? Does trans ideology unnecessarily essentialize binary genders? Should we establish a generous universal basic income? Will blockchains lead to utopia on Earth? Should blockchain enthusiasts be sent to the gulag already? Cowen enjoys occasionally getting under his elite coastal readership's skin, but this is pretty weak tea.
