There are lots of factors we could point to, but since I’m standing next to a data scientist the first one I’ll talk about is digitization. Digitization changes how people live, and it creates forms of evidence about people’s lives that we need to reckon with methodologically. Many of us are in the thick of organizations that handle some complicated datasets, traces of people and their environments, and so on. We’ve got to figure out how to engage with them, and I think that means we need new approaches if we are going to meaningfully intervene. The toolbox of user experience is only going to get us so far. So we’re going to need some friends, particularly those data scientists who are, like us, committed to the idea that datasets ought to be moored in some kind of social reality, and that they can’t just be built based on what’s expedient at the time....
