The second chapter starts with my dawning understanding that the initial article I wrote for the New York Times Magazine got the idea of the urban tribe all wrong. The groups weren’t “tight knit” as I claimed but much looser and more porous. Hundreds of people who filled out a survey on my site alerted me to this mistake. These groups both protected us from the swirl of city life and connected us to it as well. In the end of the chapter I write about Robin Dunbar’s research in which he suggests that we gossip as a form of grooming each other and expressing solidarity. We can maintain larger groups than apes because we can gossip with (aka groom) more than one person at a time.
