The notion of the ‘algorithm’ is now taking on its own force, as a kind of evocative shorthand for the power and potential of calculative systems that can think more quickly, more comprehensively and more accurately than humans. As well as understanding the integration of algorithms, we need to understand the way that this term is incorporated into organisational, institutional and everyday understandings. The discourse surrounding algorithms may then provide a focal point for analysing broader political rationalities and modes of governance. In this stream of work, the interest might not be in understanding the social powers of the technical systems, but in understanding how the notion of the algorithm itself has a kind of social power. The algorithm is now a cultural presence, perhaps even an iconic cultural presence, not just because of what they can do but also because of what the notion of the algorithm is used to project. This means that the algorithm can be part of the deployment of power, not just in terms of its function but also in terms of how it is understood as a phenomenon. Algorithmic decisions are depicted as neutral decisions, algorithmic decisions are understood to be efficient decisions, algorithmic decisions are presented as objective and trustworthy decisions, and so on. We certainly need to gain a greater view of the inside of the algorithmic systems in which we live, but we also need to develop an analysis of the cultural prominence of the notion of the algorithm, what this stands for, what it does and what it might reveal.
