With the increasing use of algorithms to govern public life, a proliferation of promises surrounding 'big data,' and an ever tighter union of academic specialists and the state bureaucracy, we are, it seems, on our way to an administrative utopia. At what cost, though? Executing Truth critically appraises this reformation of politics by way of the social sciences. It argues that what is lost with this reformation is a deeper consideration of the problematic relation of truth to politics; a problem which cuts deeper than any social science might plumb. In seeking to recover what is lost, this book offers a comprehensive study of the problem. The author works his way back from the debates in politically applied social science (or policy science) to the foundational thinkers. These include Harold Lasswell, John Dewey, Max Weber, and Georg Hegel. At the end of this journey, Executing Truth calls for a return to the everyday (or the most comprehensive basis for distinguishing between theoretical perspectives), and outlines the implications of this return for those political advisors - state executive actors - tasked with 'speaking truth to power.'
