Intellectual Humility and Political Polarization: An Exploration of Social Networks,Attitudes, and Affect

Political polarization is increasing in the United States, threatening social harmony. As this threat grows, it is important to identify factors that engender polarization and ways to disrupt them. To this end, we examined the buffering role of intellectual humility against political polarization and the potential mediating role of political heterophily (i.e., affiliation and communication with political outgroup members). Data were collected in five assessments over an eight-month period, beginning one day prior to the 2020 U.S. presidential election (N = 387) and ending in July 2021 (N = 181). Results showed that intellectual humility was associated with (1) less affective and attitudinal polarization (although in some cases this effect was only present among conservatives) and (2) more political heterophily. Cross-sectional and prospective mediation analyses suggested that intellectual humility may act through political heterophily to reduce attitude polarization. Our findings offer support for the notion that intellectual humility buffers against political polarization and provide preliminary evidence for political heterophily as one mechanism of action.     

The Perception of the Other in International Relations: Evidence for the Polarizing Effect of Entitativity

In an international relations context, the mutual images held by actors affect their mutual expectations about the Other's behavior and guide the interpretation of the Other's actions. Here it is argued that the effect of these images is moderated by the degree of entitativity of the Other—that is, the extent to which it is perceived as a real entity. Two studies tested this hypothesis by manipulating the entitativity of the European Union (EU) among U.S. citizens whose images of the EU varied along the enemy/ally dimension. Results of these studies yielded converging evidence in support of the hypothesized moderating effect of entitativity. Specifically, entitativity showed a polarizing effect on the relationship between the image of the EU and judgments of harmfulness of actions carried out by the EU.     

Populist polarization in postcolonial Philippines: Sociolinguistic rifts in online drug war discourse

Social psychological scholarship on populism explains polarization processes in terms of individual differences and group‐level divisions. However, predominant approaches often elide wider historical contexts, implicitly assuming the structural features of Western settings. Invoking insights from postcolonial psychology, we posit that populist polarization dynamics in the Global South are structurally shaped by colonial histories. Turning to the Philippines under populist President Rodrigo Duterte, we examine polarized online constructions of his controversial war on drugs. Employing a discourse‐historical approach, we uncover a structurally bifurcated view of populist polarization. We specifically unpack sociolinguistic rifts across vernacular discourses of community security uttered in Filipino versus cosmopolitan discourses of democratic integrity uttered in English. Our findings expand prevailing scholarship by illustrating postcolonial discursive possibilities of populism from above and resistance from below. We conclude with insights for studying populist polarization at the nexus of local and global inequalities.     

Electrically-manipulable spin filter based on a novel magnetic nanostructure

In order to achieve a controllable spin-polarized source, we have applied a transverse electric field to a spin filter based on a novel magnetic nanostructure with zero average magnetic field. We have analytically calculated the transmission coefficient, conductance and spin polarization for electrons to transit the device in the presence of a transverse electric field. The results demonstrate that the transmission, the conductance and the spin polarization vary sensitively with the electric field. It is shown that the performance of the spin filter can be manipulated expediently by adjusting the transverse electric field. Thus, the spin filter can be utilized as an electrically controllable spin-polarized source for spintronics applications.     

Infostorms

It has become a truism that we live in so‐called information societies where new information technologies have made information abundant. At the same time, information science has made us aware of many phenomena tied to the way we process information. This article explores a series of socio‐epistemic information phenomena resulting from processes that track truth imperfectly: pluralistic ignorance, informational cascades, and belief polarization. It then couples these phenomena with the hypothesis that modern information technologies may lead to their amplification so as to give rise to what are called “infostorms.” This points to the need for studying further the exact relations between information technologies and such infostorms, as well as the ways we may design technologies to avoid being misled away from what we have good reasons to believe.     

CLIMATE CHANGE AND THE CLASH OF WORLDVIEWS: AN EXPLORATION OF HOW TO MOVE FORWARD IN A POLARIZED DEBATE

The current gridlock around climate change and how to address our global sustainability issues can be understood as resulting from clashes in worldviews. This article summarizes some of the research on worldviews in the contemporary West, showing that these (ideal‐typical) worldviews have different, and frequently complementary, potentials, as well as different pitfalls, with respect to addressing climate change. Simultaneously, the overview shows that, because of their innate reflexivity and their capacity to appreciate and synthesize multiple perspectives, individuals inhabiting integrative worldviews may have particular potentials with respect to addressing climate change. In the conclusion I argue that the policy challenge is to develop strategies that inspire the different worldview groups to actualize their potentials while mitigating their pitfalls, as well as to unite and mobilize them around a single vision that speaks to them all.     

Drifting Further Apart? How Exposure to Media Portrayals of Muslims Affects Attitude Polarization

Political discourses about Muslim immigration in the media and on social networking sites (SNSs) are highly contentious and have the potential to further polarize societal segments, which may ultimately harm democratic processes. Especially on SNSs, politicians and citizens can circumvent journalistic filters often resulting in blatant and emotionally charged content. Using a two-wave panel design (N = 559), we investigated how positive and negative portrayals of Muslims in traditional media outlets and on SNSs influence anti-Muslim immigration attitudes among people who either agree or disagree with the encountered information. Our findings indicate that exposure to negative portrayals further reinforces anti-Muslim immigration attitudes among those who agree with the encountered information. In contrast, for those who disagree with the negative information, a backfire effect emerges, showing that anti-Muslim attitudes even decrease. This effect occurs for both SNSs and traditional media. Positive information about Muslims did not result in attitude polarization.     

Political Consequences of Partisan Prejudice

Political conflict sometimes spills over into unrelated areas of our lives. A growing literature documents examples of partisan considerations influencing judgments and behaviors in ostensibly nonpolitical contexts such as the workplace, academia, and dating, among others. To date, the focus has been on demonstrating these phenomena, with scant consideration of their downstream effects. When politics spills over into nonpolitical settings—that is, when political considerations influence nonpolitical judgments or behaviors—what are the consequences? I address this question with a novel theory and a nationally representative survey experiment. I find that norms exist regarding the spillover of political considerations into nonpolitical matters—and that spillover can have its own political consequences. When one's copartisans discriminate against members of the other party, it can lead to decreased partisan identification and depolarization. Partisan discrimination in nonpolitical settings can—in some sense ironically—reduce affective polarization. That said, partisans also appear to hold a double standard: They expect copartisans to give an edge to fellow copartisans.     

Characterization of grain-boundary dislocation networks by a combination of large-angle convergent-beam electron diffraction and weak-beam techniques

The Burgers vector of very close intrinsic dislocations in a near-Σ = 11,{311} grain-boundary in nickel is identified using a geometrical method based on local and accurate measurements of the angular deviation from perfect coincidence Σ = 11 by large-angle convergent-beam electron diffraction and of the dislocation spacing from weak-beam images of the grain boundary.
