Positive and Negative Peace as Predictors of Pandemic Preparedness: Evidence from a Micro- and Macro-Level Investigation During the Onset of the COVID-19 Pandemic

The COVID-19 pandemic has generated unprecedented human loss and financial difficulties worldwide. In line with recent calls for social sciences to help collective efforts to address COVID-19, we investigated the link between peace and pandemic preparedness, advancing the literatures on negative (i.e., absence of direct violence) and positive peace (i.e., absence of structural violence and presence of equality) and governments' crisis preparedness as well as crisis relief efforts. Two studies tested whether both positive and negative peace predict pandemic preparedness, operationalized as COVID-19 tests, cases, and positivity rates, during the onset of the pandemic. Study 1 did so at the national level across 155 countries; Study 2 did so at a local level, across 3144 counties within the United States. Even after controlling for population size, population density, GDP, and amount of air travel, higher levels of both negative and positive peace predicted a greater number of COVID-19 tests per one million people, fewer overall COVID-19 cases, and a lower positivity rate. These findings point to the possibility that by promoting peace, governments and the international community could potentially become better prepared to handle future pandemics and other crises.     

Distinguishing intellectual humility and general humility

Two studies provide evidence for distinguishing intellectual humility (IH) from general humility (GH). Humility involves (a) an Accurate View of Self and (b) the ability to regulate egotism and cultivate an other-oriented stance; IH is a subdomain of humility that involves (a) having an accurate view of one’s intellectual strengths and limitations and (b) the ability to negotiate ideas in a fair and inoffensive manner. First, we present a theoretical framework for distinguishing these constructs. In Study 1, with a sample of undergraduate students (N = 1097), we used confirmatory factor analysis to provide empirical evidence for this distinction. We also found that IH predicted unique variance in openness to experience relative to GH. In Study 2, we examined additional evidence of discriminant validity with another sample of college students (N = 355). IH also predicted unique variance in need for cognition, objectivism, and religious ethnocentrism relative to GH.

Libertarian independent ideologies predict lower support for and participation in COVID-19 safety precautions among Americans

In the US, higher conservatism has consistently been linked to lower receptiveness toward COVID-19 safety precautions. The present studies extended these findings by examining how specific dimensions of conservatism contributed to this relationship. Three studies (total N = 1123) found that conservatives with higher Libertarian Independent attitudes reported less support for and participation in COVID-19 safety precautions. These effects remained robust after controlling for demographics, general political orientation, COVID-19 threat perception, and personality. These findings offer nuanced insight into how those with different conservative ideologies responded to COVID-19 safety precautions.     

Meta‐CART: A tool to identify interactions between moderators in meta‐analysis

In the framework of meta‐analysis, moderator analysis is usually performed only univariately. When several study characteristics are available that may account for treatment effect, standard meta‐regression has difficulties in identifying interactions between them. To overcome this problem, meta‐CART has been proposed: an approach that applies classification and regression trees (CART) to identify interactions, and then subgroup meta‐analysis to test the significance of moderator effects. The previous version of meta‐CART has its shortcomings: when applying CART, the sample sizes of studies are not taken into account, and the effect sizes are dichotomized around the median value. Therefore, this article proposes new meta‐CART extensions, weighting study effect sizes by their accuracy, and using a regression tree to avoid dichotomization. In addition, new pruning rules are proposed. The performance of all versions of meta‐CART was evaluated via a Monte Carlo simulation study. The simulation results revealed that meta‐regression trees with random‐effects weights and a 0.5‐standard‐error pruning rule perform best. The required sample size for meta‐CART to achieve satisfactory performance depends on the number of study characteristics, the magnitude of the interactions, and the residual heterogeneity.     

Are autistic traits autistic?

According to the extreme male brain theory of autism ( Baron‐Cohen, 2002 ), autistic traits would be extreme manifestations of typical male behaviours. The Auyeung et al. (2009) paper establishes a link between autistic traits and higher fetal testosterone (fT) levels in typically developing children. We argue that the construct behind this relationship needs further investigation. First, the link between fT levels and sexually dimorphic traits, that are for example, associated with empathizing and systemizing, is controversial. Likewise, describing autistic behaviours as being extreme male‐like is debatable. The cerebral hemisphere laterality pattern of individuals with autism also seems to differ from the pattern typically observed in males. Moreover, the parallel that should exist, according to the fT theory, between individuals with autism and individuals with congenital adrenal hyperplasia (CAH), because of their high fT levels, is unclear. The theory implying fT levels in autism fails to account for a big part of autism, and the link between fT and normal ‘autistic traits’ hardly demonstrates the causal link between fT and autism.
