 Weisberg and Muldoon (2009) introduce a model where actors investigate an “epistemic landscape”—a grid where each section represents a problem in science, of varying epistemic importance. Figure 3 shows an example of such a landscape. Scientists are randomly scattered on the landscape, and follow search rules that are sensitive to this importance. Investigators can then ask: how well did scientists do? Did they fully search the landscape? Did they find the peaks?
