Learning from diversity: Public reason and the benefits of pluralism

The New Diversity Theory (NDT) represents a novel approach to public reason liberalism, providing an alternative to the traditional, Rawlsian public reason paradigm. One of the NDT's distinctive features is its emphasis on the potential advantages of a diverse society, with a particularly strong focus on the epistemic benefits of diversity. In this paper, I call into question whether societal diversity has the epistemic benefits that New Diversity theorists claim. I highlight a number of pernicious epistemic phenomena that tend to arise in diverse contexts, ultimately arguing that the only feasible way around these epistemic pitfalls is through widespread convergence on certain intellectual virtues. If these virtues are indeed necessary, then the benefits highlighted by the NDT should only be expected in societies that reflect certain kinds of diversity. More precisely, only the kinds of diversity that can still persist despite homogenization along the lines of certain intellectual virtues are compatible with the NDT's claims. Building upon this insight, I then highlight features of the NDT that require further development in order for it to serve as a compelling alternative to its Rawlsian counterpart.
