Creativity and Practical Underdetermination: How Experimental Science Steps into the Epistemic Adjacent Possible

Abstract This article offers a novel take on what philosophers have called problems of “practical underdetermination” in order to identify a form of creative epistemic agency operative in the means by which researchers cope with such problems. In developing my analysis, I contrast my “experimental dead-space” (EDS) formulation of practical underdetermination with the more standard “epistemic gap” formulation. Drawing on prior work, I embed the idea of an EDS within a broader unit of analysis—a “research program”—and identify an experimental dead-space with what I call, borrowing terms from Stuart Kauffman, an “epistemic adjacent possible.” This enables me to characterize the form of creativity I have in mind. Finally, I revisit the case study for which I originally formulated the idea of an EDS in order to show how my expanded analysis enables us to appreciate how research platforms in experimental science can creatively develop in genuinely novel, “unprestatable” ways.
