For the longest time, when I was thinking through networks, I was thinking that the network isn't the node and the connection, which is what you see on a graph, but it's actually that space. If you didn't have that space, you wouldn't have a network. You would just have a blob. And so if we think about everything that needs to be emptied out in order for these connections to emerge, a very different idea of networks emerges. And I think that what's so key about that, and what I've been trying to think through more and more, is that these spaces are spaces of indifference. They contain difference, their indifference. But also, they’re forms of infrastructure that enable a caring kind of indifference. I talk in the book about the housing study, which was key to the rise of homophily. And it was a biracial housing community. It was segregated within itself, either by building, or in one building, by floor. And it was studied in order to understand the impact of tenant morale on democratization and positive forms of social engineering. Long story short, they focused on the reaction of white residents, and friendship patterns of White residents in terms of three closest friends, irregardless of where they lived, whether or not they lived in the housing project, and their attitudes to living in biracial housing. Should it exist, and did they think it should exist? So what was important is that in order to come up with the term homophily, they took out all the responses of the Black residents. They actually took out the responses of the White ambivalents, which would be the largest category. But without the Black residents, the network of friendship would never have emerged, because the questions were all around the presence of the Black residents who were there. These gaps were people, they’re populated by them. What's interesting is you go back to the archive, in the interviews, the Black residents make it very clear that they are for biracial housing, and thus called liberals, not because of a bizarre notion of liberalism, but rather because they were being offered equal housing for the first time. And they said that these are the conditions under which we finally get good housing. And my attitude towards my White neighbors is one of indifference. You're here, that's fine. And this is how we're going to live together.
