Metacognitive mental states are mental states about mental states. For example, I may be uncertain whether my belief is correct. In social discourse, an interlocutor’s metacognitive certainty may constitute evidence about the reliability of their testimony. For example, if a speaker is certain that their belief is correct, then we may take this as evidence in favour of their belief, or its content. This paper argues that, if metacognitive certainty is genuine evidence, then it is disproportionate evidence for extreme beliefs. (...) In support of the argument, we report findings from five studies with different participant samples, designs, and measures. These studies show that, the more extreme an agent’s belief (positive or negative), the more certain they are about it, and vice versa. This relationship might contribute to moralism, virtue signalling, and polarisation, which in turn may be epistemically and morally problematic. Therefore, we caution against taking metacognitive certainty as genuine evidence. (shrink)

General epistemic polarization arises when the beliefs of a population grow further apart, in particular when all agents update on the same evidence. Epistemic factionalization arises when the beliefs grow further apart, but different beliefs also become correlated across the population. I present a model of how factionalization can emerge in a population of ideally rational agents. This kind of factionalization is driven by probabilistic relations between beliefs, with background beliefs shaping how the agents’ beliefs evolve in the light of (...) new evidence. Moreover, I show that in such a model, the only possible outcomes from updating on identical evidence are general convergence or factionalization. Beliefs cannot spread out in all directions: if the beliefs overall polarize, then it must result in factionalization. (shrink)

In contrast to most literature on cosmopolitanism, which focuses on its elite forms, this article analyzes how ordinary people bridge racial boundaries in everyday life. It is based on interviews with 150 non-college-educated white and black workers in the United States and white and North African workers in France. The comparison of the four groups shows how differences in cultural repertoires across national context and structural location shape distinct anti-racist rhetorics. Market-based arguments are salient among American workers, while arguments based (...) on solidarity and egalitarianism are used by French, but not by American, workers. Minority workers in both countries employ a more extensive toolkit of anti-racist rhetoric as compared to whites. The interviewed men privilege evidence grounded in everyday experience, and their claims of human equality are articulated in terms of universal human nature and, in the case of blacks and North Africans, universal morality. Workers' conceptual frameworks have little in common with multiculturalism that occupies a central place in the literature on cosmopolitanism. We argue that for the discussion and practice of cosmopolitanism to move forward we should shift our attention to the study of multiple ordinary cosmopolitanisms. (shrink)

With the advancement of marketization, China has achieved rapid economic growth and economic class differentiation. This research analyzes the data from China’s livelihood survey, divides the urban Chinese into five socio-economic classes, and tests their preferences and tendencies for income redistribution. It obtains the general attitude differences in subsidy policy and income inequality during COVID-19. Our conclusion are consistent with the existing literature to a great extent; that is, personal factors play a crucial role in the attitude of Chinese citizens. (...) In the analysis of situational factors, the results show that the higher the level of marketization, the people are more likely to have stronger negative emotions about subsidy or redistribution policies. Further analysis shows that people with the lowest income are susceptible to the fact that income inequality has become significant and show a strong willingness to support the government’s redistribution policy. In contrast, middle-class people tend to favor the government’s redistribution policy, although they will not benefit much from the redistribution policy. Therefore, they lack the motivation to support the government in vigorously implementing the subsidy policy. Significantly, high-income people are indifferent, as they lack such motivation even more. The difference in redistribution preferences between upper-class and lower-class groups signals polarization in Chinese society, especially income redistribution. (shrink)

Polarization poses a critical threat to the stability of nations around the world, as it impacts climate change, populism, democracy, and global health. This perspective examines the conceptual understanding, measurement challenges, and potential interventions for polarization. Our analysis highlights the distinction and interactions between the individual and collective levels of polarization, conceptually, methodologically, and in terms of interventions. We conclude by pointing out future directions for understanding polarization and highlighting the interrelations between polarization and other social phenomena. -/- .

The importance of online social spaces is growing. New Web 2.0 resources allow the creation of social networks by any netizen with minimal technical skills. These communities can be extremely narrowly focussed. In this paper, I identify two potential costs of membership in narrowly focussed virtual communities. First, that narrowly focussed communities can polarise attitudes and prejudices leading to increased social cleavage and division. Second, that they can lead sick individuals to revel in their illness, deliberately indulging in their disease (...) and denying the edicts of the medical profession. I specifically examine illness communities centred on the now defunct Multiple Personality Disorder. I highlight these potential problems and point to some technologies that may help combat them.
