This paper outlines a neo-Weberian approach to state-sponsored social closure in professional formation. Despite its advantages, state decision-making is not typically well-defined or examined in neo-Weberian analyses. Neo-Weberianism is differentiated from Max Weber's own work on social action and rationality, which generally provides a more subtle interpretation of state socio-political processes. The paper explores how policy formation can be more incisively analyzed inside the black box of state decision-making from a Weberian perspective. This is exemplified by the passage of the 1858 Medical Act in the United Kingdom establishing the statesupported medical profession. While further work is necessary in filling in the black box, this paper charts an important future path for neo-Weberian analyses of professions, and their relationship with the state.
