 Diversity has emerged several times in our discussion of formal social epistemology. Credit incentives can encourage scientists to choose a diversity of problems. In network models, a transient diversity of beliefs is necessary for good inquiry. Let us now turn to models that tackle the influence of diversity more  explicitly.[10]  It has been suggested that cognitive diversity benefits epistemic communities because a group where members start with different assumptions, use different methodologies, or reason in different ways may be more likely to find truth.
