Explaining the Inexplicable: Differences in Attributions for the Holocaust in Germany,Israel, and Poland

Seventy years have passed since the Holocaust, but this cataclysmic event continues to reverberate in the present. In this research, we examine attributions about the causes of the Holocaust and the influence of such attributions on intergroup relations. Three representative surveys were conducted among Germans, Poles, and Israeli Jews to examine inter‐ and intragroup variations in attributions for the Holocaust and how these attributions influence intergroup attitudes. Results indicated that Germans made more external than internal attributions and were especially low in attributing an evil essence to their ancestors. Israelis and Poles mainly endorsed the obedient essence attribution and were lowest on attribution to coercion. These attributions, however, were related to attitudes towards contemporary Germany primarily among Israeli Jews. The more they endorsed situationist explanations, and the less they endorsed the evil essence explanation, the more positive their attitude to Germany. Among Germans, attributions were related to a higher motivation for historical closure, except for the obedience attribution that was related to low desire for closure. Israelis exhibited a low desire for historical closure especially when attribution for evil essence was high. These findings suggest that lay perceptions of history are essential to understanding contemporary intergroup processes.     

Are We All Overconfident in the Long Run? Evidence from One Million Marathon Participants

In this project, we measured overconfidence in a large, heterogeneous sample making familiar, repeated choices in a natural environment that provided direct feedback. Specifically, in study 1, we elicited predictions of own finishing time among participants of the 2012 Warsaw Marathon. The participants' prediction errors were highly correlated with the change in pace over the course of the run: overly optimistic forecasters slowed down more in the second half. In study 2, we consequently took this slowdown as a proxy for overconfidence and used existing field data of one million participants in several large marathons for which split times are available (but own predictions are not). Both studies indicate that men as well as the youngest and oldest participants tend to be more confident. In study 2, we were able to investigate national and cultural dimensions. We found confirmation of previously reported findings of relative overconfidence in Asians. Additionally, we show some largely novel results, in particular that relatively conservative societies tend to be relatively overconfident. Copyright © 2016 John Wiley & Sons, Ltd.     

Development and validation of the REMINT: a reflection measure for individuals and teams

A growing number of studies have investigated the role of team reflexivity, the extent to which teams reflect on and adapt their functioning. However, the way team reflexivity has been conceptualized and operationalized reveals several weaknesses, in particular the conception as a unidimensional construct. To provide greater conceptual clarity, we therefore propose a team reflexivity framework that integrates four interacting but distinct reflexive processes. In four studies, we focus on reflection as a fundamental reflexive process, and develop and validate an extended multidimensional reflection measure that captures the relevant dimensions of quality and quantity of reflection and the key transition processes of information seeking and information evaluation. Moreover, in order to delineate two common composition methods, we develop and validate a direct consensus and a referent-shift consensus version of the reflection measure. Data collected from a total of 803 students and employees in four studies revealed excellent construct validity, as well as good nomological validity (Studies 1 and 2). Furthermore, we found evidence of the criterion-related validity at the team level (Study 3) and the individual level (Study 4). Together, the results demonstrate the effectiveness of our measure, revealing consistent relations with outcome measures and diverse behavioural indicators across different contexts.     

A Proof System for Classical Logic

An operation on inferential rules, called H-operation, is used to minimize the axiom basis for classical logic.     

Obedience to authorities is not unconditional: Differential effects of COVID-19 threat on three facets of RWA in Poland and Germany

Collective authoritarian responses to threat might differ depending on whether people trust collective authorities in reducing threat. Thus, we tested the differential effects of epidemic threat on three facets of right-wing authoritarianism, in Germany (a country with high authorities' efficacy in responses to COVID-19) and Poland (low authorities' efficacy context). Two representative sample longitudinal studies performed in Poland (N = 892) and Germany (N = 883) showed that in Germany feelings of COVID-19 threat explained increases in authoritarian submission and (to a lesser extent) authoritarian aggression, whereas in Poland such feelings of threat explained changes in authoritarian aggression and conventionalism after the pandemic, but did not alter authoritarian submission. These findings suggest that specific authoritarian reactions to threat (submissive vs. conventionalist) might depend on the general trust in authorities' ability to respond to crises.

Approaching Shared Heroes: Cultural Transfer and Transnational Jewish History

This special issue of Jewish History is devoted to shared heroes in Judaism, Christianity, and Islam. It explores diverse images of heroes that are shared by at least two of these religious traditions by comparing each figure’s origin, inventions, and reinventions within varying cultural contexts in antiquity, the Middle Ages, and the early modern period and by highlighting the cross-cultural significance of their counterstories and entangled histories. The construction and deconstruction, interpretation and reception of these heroic figures and their sociocultural roles over time and space bear witness to the encounters of Jews and Judaism with neighboring cultures. The approaches to our subject presented in this collection illuminate how the long-established rubric of “the hero” benefits from a cross-cultural approach. In turn, empirical data culled from the cross-cultural study of heroes demonstrate the inner workings of cultural transfer and, we believe, contribute an original perspective to the field of transnational history, which focuses on cultural entanglement.     

The stressors of being young and Black: Cardiovascular health and Black young adults

Objective: To examine the impact of stressors relevant to the lives of Black young adults including racial, financial, occupational, and general stress and psychological distress on cardiovascular disease (CVD) risk. Specifically, this study examined the relationship between multiple psychosocial stressors and two CVD risk indicators (i.e. obesity and blood pressure).

Design: This study used a quantitative design which included surveys, the collection of anthropometric and blood pressure (BP) measures. Participants were 124 Black college students aged 18 to 27 years old. Main Outcome Measures: Participants completed measures to assess psychological distress, general, occupational, financial and racial stress. Measures of body mass index (BMI), waist-to-hip ratio (WHR) and BP were collected to assess CVD risk.

Results: Findings indicated a significant effect of internalised racism on BMI and a significant effect of individual racial stress on diastolic BP. Also, depression was significantly associated with systolic BP. There were no significant results for WHR.

Conclusion: Findings suggested that the relationship among racial stress, psychological distress and CVD be further explored.
