​I use network models to simulate social learning situations in which the dominant group ignores or devalues testimony from the marginalized group. I find that the marginalized group ends up with several epistemic advantages due to testimonial ignoration and devaluation. The results provide one possible explanation for a key claim of standpoint epistemology, the inversion thesis, by casting it as a consequence of another key claim of the theory, the unidirectional failure of testimonial reciprocity. Moreover, the results complicate the understanding (...) and application of previously discovered network epistemology effects, notably the Zollman effect (Zollman 2007, 2010). (shrink)

I analyze the role of infinite idealizations used in the renormalization group (RG hereafter) method in explaining universality across microscopically different physical systems in critical phenomena. I argue that despite the reference to infinite limit systems such as systems with infinite correlation lengths during the RG process, the key to explaining universality in critical phenomena need not involve infinite limit systems. I develop my argument by introducing what I regard as the explanatorily relevant property in RG explanations: linearization* property; I (...) then motivate and prove a proposition about the linearization* property in support of my view. As a result, infinite limit systems in RG explanations are dispensable. (shrink)

Diversity of practice is widely recognized as crucial to scientific progress. If all scientists perform the same tests in their research, they might miss important insights that other tests would yield. If all scientists adhere to the same theories, they might fail to explore other options which, in turn, might be superior. But the mechanisms that lead to this sort of diversity can also generate epistemic harms when scientific communities fail to reach swift consensus on successful theories. In this paper, (...) we draw on extant literature using network models to investigate diversity in science. We evaluate different mechanisms from the modeling literature that can promote transient diversity of practice, keeping in mind ethical and practical constraints posed by real epistemic communities. We ask: what are the best ways to promote an appropriate amount of diversity of practice in scientific communities? (shrink)

There is an "under-representation problem” in philosophy departments and journals. Empirical data suggest that while we have seen some improvements since the 1990s, the rate of change has slowed down. Some posit that philosophy has disciplinary norms making it uniquely resistant to change (Antony and Cudd 2012; Dotson 2012; Hassoun et al. 2022). In this paper, we present results from an empirical case study of a philosophy department that achieved and maintained male-female gender parity among its faculty as early as (...) 2014. Our analysis extends beyond matters of gender parity because that is only one, albeit important, dimension of inclusion. We build from the case study to reflect on strategies that may catalyze change. (shrink)

When solving a complex problem in a group, should group members always choose the best available solution that they are aware of? In this paper, I build simulation models to show that, perhaps surprisingly, a group of agents who individually randomly follow a better available solution than their own can end up outperforming a group of agents who individually always follow the best available solution. This result has implications for the feminist philosophy of science and social epistemology.

This study investigated the status of research integrity knowledge among dental undergraduates from 34 Chinese universities in 5 key demographic regions. Questionnaires regarding the status of research integrity, including perception, attitude, and firsthand experience of scientific research integrity, were distributed to dental undergraduates of 34 Chinese universities. These universities were from 5 key demographic regions of China, i.e., eastern, western, northern, southern, and central. The questionnaires filled out by 1514 participants were further analyzed. The results showed that among the participants, (...) nearly 70% acquire scientific integrity knowledge through courses, as well as ideological and political education, while the remaining students acquire scientific integrity knowledge through other means, such as books and conferences. From the attitude perspective, most students (80-90%) oppose scientific misconduct. However, a few students also have an insufficient understanding of scientific misconduct and still need to improve their scientific research integrity training further. We also found that the research integrity training and the surrounding research environment affect students' attitudes and self-behavior regarding scientific integrity. Our findings indicate that the ethical academic and research environment, implementation of scientific integrity courses in the curriculum, and proper supervision are vital in improving scientific research integrity knowledge in dental undergraduates in Chinese universities.
