Political polarization: a curse of knowledge?

Purpose: Could the curse of knowledge influence how antagonized we are towards political outgroups? Do we assume others know what we know but still disagree with us? This research investigates how the curse of knowledge may affect us politically, i.e., be a cause of political polarization. Background: Research on the curse of knowledge has shown that even when people are incentivized to act as if others do not know what they know, they are still influenced by the knowledge they have. Methods: This study consists of five studies consisting of both experimental and non-experimental and within- and between-subjects survey designs. Each study collected samples of 152-1,048. Results: Partisans on both sides overestimate the extent to which stories from their news sources were familiar to contrapartisans. Introducing novel, unknown facts to support their political opinion made participants rate political outgroup members more negatively. In an experimental design, there was no difference in judging an opponent who did not know the same issue-relevant facts and someone who did know the same facts. However, when asked to compare those who know to those who do not, participants judged those who do not know more favorably, and their ratings of all issue-opponents were closer to those issue-opponents who shared the same knowledge. In a debiasing experiment, those who received an epistemological treatment judged someone who disagreed more favorably. Conclusion: This research provides evidence that the curse of knowledge may be a contributing cause of affective political polarization.

Global Consciousness Predicts Behavioral Responses to the COVID-19 Pandemic: Empirical Evidence From 35 Cultures.

COVID-19 has drastically changed human behaviors and posed a threat to globalism by spurring a resurgence of nationalism. Promoting prosocial behavior within and across borders is of paramount importance for global cooperation to combat pandemics. To examine both self-report and actual prosocial behavior, we conducted the first empirical test of global consciousness theory in a multinational study of 35 cultures (N = 18,171 community adults stratified by age, gender, and region of residence). Global consciousness encompassed cosmopolitan orientation, identification with all humanity, and multicultural acquisition, whereas national consciousness reflected ethnic protection. Both global consciousness and national consciousness positively predicted perceived risk of coronavirus and concern about coronavirus, after controlling for interdependent self-construal. While global consciousness positively predicted prosocial behavior in response to COVID-19, national consciousness positively predicted defensive behavior. These findings shed light on overcoming national parochialism and provide a theoretical framework for the study of global unity and cooperation.

The "chicken-and-egg" development of political opinions.

Twin studies have revealed political ideology to be partially heritable. Neurological research has shown that ideological differences are reflected in brain structure and response, suggesting a direct genotype-phenotype link. Social and informational environments, however, also demonstrably affect brain structure and response. This leads to a "chicken-and-egg" question: do genes produce brains with ideological predispositions, causing the preferential absorption of consonant information and thereby forming an ideology, or do social and informational environments do most of the heavy lifting, with genetic evidence the spurious artifact of outdated methodology? Or are both inextricably intertwined contributors? This article investigates the relative contributions of genetic and environmental factors to ideological development using a role-play experiment investigating the development of opinions on a novel political issue. The results support the view that the process is bidirectional, suggesting that, like most traits, political ideology is produced by the complex interplay of genetic and (social/informational) environmental influences.

The slave Silvestre´s disputed sale: corporal punishment, mental health, sexuality and ´vices´ in Recife, 1869-1879

It presents the slave Silvestre´s case that can serve as micro-historical evidence and allows us to examine how traditional and more modern concepts of mental health, commerce, punishment, gender and sexuality commingled in Recife, that was then Brazil´s third largest urban center.(AU)

Challenges faced by service providers in the delivery of Assertive Community Treatment.

This qualitative study examined the delivery of Assertive Community Treatment from the perspective of service providers of 4 ACT teams in southeastern Ontario. Overall, providers were positive about their involvement with ACT. Eight tensions experienced in the context of delivering services emerged: negotiating governance structures; providing 24-hour coverage; balancing the clinical-administrative responsibilities of team leaders; accessing hospital beds; meeting local population needs; integrating treatment and rehabilitation; changing services to meet changes in the population being served; and implementing ambiguous ACT standards. Framing these challenges in the context of ACT structures and the broader community mental health system, the study suggests possibilities for the ongoing development of the model to facilitate the realization of the ACT vision.
