My weekend post positing a possible inverse relationship between a city’s average attractiveness and the prevalence of stranger-flirtation in bars prompted a few responses, from Ilya Somin at Volokh Conspiracy, Heather, and Glen Whitman. And to clarify for Glen: Yep, my implicit assumption was that in a high-average-attractiveness city, people will tend to have more sufficiently attractive prospective partners about whom they also have other useful information via their other professional and social networks.
