This article identifies two major sources of epistemological uncertainty in simulation, the problem of representation—how similar is the model to reality?—and the problem of expert opinions—what status can be ascribed to expert opinions? In the late 1950s, philosophers Olaf Helmer and Nicholas Rescher proposed an epistemology that purportedly provided the foundation for understanding simulation and comparable predictive endeavors as scientific. Published in 1959 as “On the Epistemology of the Inexact Sciences,” it claimed that under certain provisions, expert opinions should be acknowledged on the same epistemological level as theories or data. Doing so would solve the problem of expert opinion. While this proposal was innovative and soundly argued, it was not much received. Yet, within futures studies, it contributed to the development of an epistemological position, and eventually a new concept of science, that acknowledge and integrate the uncertainty implied in any predictive science. This article argues that it is worthwhile to reconsider Helmer and Rescher’s proposal and the ensuing debates about the nature of science in futures studies, as they provide a strategic position from which to re-conceptualize the use of expert opinions in simulation studies and thus to establish a more adequate epistemology for simulation in other fields of science.
