Standard Deviation

You have a number. Not your phone number. Not your social security number, though that one matters more than most of us like to think about. I mean another number, one that follows you through databases you will never see, aggregated from purchases you barely remember making, from the length of time you hovered over a photograph before scrolling past, from the route you took to work last Tuesday and whether you lingered outside that coffee shop or walked directly to the train. This number has a name in China. They call it a Social Credit Score. But the American version has no single name because it has no single keeper. It lives distributed across credit bureaus and insurance actuaries, across hiring algorithms and rental application systems, across the predictive models that decide whether you see an advertisement for a luxury watch or a payday loan. You did not consent to being numbered. But you are numbered nonetheless.
