Diversity, Ability, and Expertise in Epistemic Communities

Abstract: The Hong and Page ‘diversity trumps ability’ result has been used to argue for the more general claim that a diverse set of agents is epistemically superior to a comparable group of experts. Here we extend Hong and Page’s model to landscapes of different degrees of randomness and demonstrate the sensitivity of the ‘diversity trumps ability’ result. This analysis offers a more nuanced picture of how diversity, ability, and expertise may relate. Although models of this sort can indeed be suggestive for diversity… Show more

“…Among them, six studies identically agreed with the result that the DTA phenomenon is robust for problem-solving cases about highly unpredictable issues (Grim et al 2018; Holman et al 2018; Hong and Page 2004; Singer 2018; Thoma 2015; Weymark 2015). 7 The result held even when the definition of “experts” was altered from a problem-specific knowledge holder to a transportable knowledge holder (Grim et al 2018; Holman et al 2018). A modified ELM version also gave support to the DTA phenomenon holding only for a rugged landscape (Thoma 2015, 466).…”

“…There is also a substantial body of work that seeks effect modifiers to explain when diversity does and when it does not improve group performance (Bear and Woolley 2011; Guillaume et al 2017; Joshi, Liao, and Roh 2011; Smith-Doerr, Alegria, and Sacco 2017). Consequently, some object that BCD is exaggerated and oversimplified (Eagly 2016; Grim et al 2019).…”

“…Mathematical models use difference and differential equation to represent how populations change over time; computer simulations rely on simple update rules in discrete time steps to recreate the behavior of complex systems. This makes mathematical and computational models extremely illuminating tools to study a wide variety of phenomena that have traditionally puzzled philosophers, such as political organizations or the behavior of epistemic communities—for recent examples in these areas, see Bruner () and Grim et al ().…”
