It is difficult to see the political structure of data, because data maintains a veneer of scientistic objectivity. But data is inherently a form of politics, argues Jeffrey Alan Johnson. Data does not just allocate material things of value, it allocates moral values as well. Data producers encode a state of the world at a given time, which is then decoded by data users to shape social practice. As such, a political theory of data, grounded in distributive and relational information justice, is necessary.
