In this introduction to the Topical Collection on Social and Cognitive Diversity in Science, we map the questions that have guided social epistemological approaches to diversity in science. Both social and cognitive diversity of different types is claimed to be epistemically beneficial. The challenge is to understand how an increase in a group’s diversity can bring about epistemic benefits and whether there are limits beyond which diversity can no longer improve a group’s epistemic performance. The contributions to the Topical Collection (...) discuss various proposals to maintain an appropriate amount of cognitive diversity in science, for instance, by recruiting and retaining practitioners from underrepresented social groups, providing incentives for explorative and risky research, encouraging interdisciplinary collaborations and stakeholder participation in research, requiring industry scientists to share their evidence, and developing strategies to encounter politically motivated attempts to manufacture doubt. To be successful, efforts to promote diversity in science should anticipate risks related to institutional interventions, navigate trade-offs between different types of epistemically good outcomes, and identify hidden costs that such policies may cause for various actors. Such efforts need to be assessed not only from an epistemic perspective but also from the point of view of fairness and the political legitimacy of scientific institutions. (shrink)

Interdisciplinarity is strongly promoted in science policy across the world. It is seen as a necessary condition for providing practical solutions to many pressing complex problems for which no single disciplinary approach is adequate alone. In this article we model multi- and interdisciplinary research as an instance of collective problem solving. Our goal is to provide a basic representation of this type of problem solving and chart the epistemic benefits and costs of researchers engaging in different forms of cognitive coordination. (...) Our findings suggest that typical forms of interdisciplinary collaboration are unlikely to find optimal solutions to complex problems within short time frames and can lead to methodological conservatism. This provides some grounds for both reflecting on current science policy and envisioning more effective scientific practices with respect to interdisciplinary problem solving. (shrink)

Philosophers of science have in recent years presented arguments in favour of increasing cognitive diversity, diversity of social locations, and diversity of values and interests in science. Some of these arguments align with important aims in contemporary science policy. The policy aims have led to the development of institutional measures and instruments that are supposed to increase diversity in science and in the governance of science. The links between the philosophical arguments and the institutional measures have not gone unnoticed. Philosophers (...) have even explicitly suggested that institutional measures could be used to increase diversity in science. But philosophical criticisms of the existing institutional instruments have also been presented. Here I review some recent case studies in which philosophers examine actual attempts to increase diversity in science by using institutional measures implemented from the top down—attempts that have failed in one way or another. These studies examine attempts to involve citizens or stakeholders in the governance of science and technology and attempts to increase the number of interdisciplinary collaborations. They draw attention to the limitations of such instruments, calling into question the most optimistic visions of using institutional instruments to increase diversity in science. (shrink)

The social epistemology of science would benefit from paying more attention to the nature of argumentative exchanges. Argumentation is not only a cognitive activity but a collaborative social activity whose functioning needs to be understood from a psychological and communicative perspective. Thus far, social and organizational psychology has been used to discuss how social diversity affects group deliberation by changing the mindset of the participants. Argumentative exchanges have comparable effects, but they depend on cognitive diversity and emerge through critical interaction. (...) An example of a cognitive psychological theory is discussed that explains how mutual reasoning affects how we think, make decisions, and solve problems, as well as how cognitive biases may facilitate an efficient division of cognitive labor. These observations are compared with the existing results in the social epistemology of science. Moreover, I explicate the conceptual differences between the distributed and social processing of information. While argumentative exchanges belong to the latter domain, most existing simulations model distributed processing, which may compromise their real-world relevance and proper conceptual interpretation. However, I aim not to criticize the existing simulation methods but to promote an approach from the cognitive psychology of reasoning that complements the current use of organizational psychology and computer simulations by investigating a different set of mechanisms relating to similar phenomena of interest in the social epistemology of science.

ABSTRACT The “diversity trumps ability” model is often interpreted as a mechanism supporting epistemic democracy. However, as a variety of empirical and mathematical studies have shown, if we attempt to test the realism of the model, it turns out that it points as much toward epistocracy as democracy. This might appear to leave epistocracy with an advantage, since its rationale is not usually thought to rely on the DTA but on the obvious relevance of expertise to making complex decisions. Yet (...) if we apply the same test to epistocracy that we should apply to epistemic democracy—the test of realism—we find that it, too, is unsustainable. This suggests that epistemic democracy and epistocracy alike are indefensible on the basis of the abstract assumptions about diversity and expertise on which the DTA is predicated. (shrink)
