Summary	The valuation studies method treats valuation—the production, measurement, ordering, and contestation of worth—as a social practice to be studied empirically rather than a hidden mental act or a settled economic fact. Consolidated by Claes-Fredrik Helgesson and Fabian Muniesa and complemented by Michèle Lamont's comparative sociology of valuation and evaluation, it follows how rankings, metrics, prices, and evaluation procedures actually do their work, and asks how worth comes to be, by whom, with which devices, and to what effect.	The infrastructure studies method, developed by Susan Leigh Star, Geoffrey Bowker, and Karen Ruhleder, studies the normally invisible relational systems—standards, classifications, pipes, protocols, and installed bases—on which modern life silently depends. Its signature move is 'infrastructural inversion': deliberately foregrounding the background, treating the taken-for-granted substrate as the object of analysis, and reading its standards, classifications, and breakdowns to understand how it shapes work, knowledge, and lives.
