Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty

This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions as they used the same data to independently test the same prominent social science hypothesis: that greater immigration reduces support for social policies among the public. In this typical case of social science research, research teams reported both widely diverging numerical findings and substantive conclusions despite identical start conditions. Researchers' expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes. More than 95% of the total variance in numerical results remains unexplained even after qualitative coding of all identifiable decisions in each team's workflow. This reveals a universe of uncertainty that remains hidden when considering a single study in isolation. The idiosyncratic nature of how researchers' results and conclusions varied is a previously underappreciated explanation for why many scientific hypotheses remain contested. These results call for greater epistemic humility and clarity in reporting scientific findings.

How the Welfare-State Regime Shapes the Gap in Subjective Well-Being Between People With and Without Disabilities

This paper focuses on disability, an under-researched area of inequality, and subjective well-being. According to social production function theory, people with a disability do not have the same opportunities as people without disabilities to obtain resources, instrumental goals, and ultimately subjective well-being. Social participation and employment seem to be crucial mechanisms behind such disparities. The social system of a country (macro level) also shapes the gap in subjective well-being between both groups. The main objective of this paper is to analyse the gap in subjective well-being between people with and without disabilities. How is this gap linked to social participation and labour market integration, and how does the welfare-state regime shape the gap in subjective well-being between people with and without disabilities? The core of this research are multilevel analyses of cumulative European Social Survey data from 31 European countries. The results reveal that people with disabilities show significantly lower subjective well-being than people without disabilities. Welfare-state regimes have an effect on this gap, with social-democratic (and family-oriented) Nordic countries performing best in providing equal living conditions for people with and without disabilities.

Authoritarianism Beyond Disposition: A Literature Review of Research on Contextual Antecedents

A core debate in authoritarianism research relates to the stability of authoritarianism, i.e., whether it is a dispositional phenomenon socialized in early childhood or even genetically predisposed, or whether it is impacted by time-sensitive, exterior conditions. Whereas certain individual authoritarian tendencies emerge as a rather stable personality trait, there is also empirical evidence for a dynamic influence of external factors. This review article provides a conceptual multilevel framework for the study of authoritarianism and offers an insight into the state-of-research on socialization and situational influences, with a particular focus on threat. Findings are discussed with regard to key theories of authoritarianism.

How Migration Policy Shapes the Subjective Well-Being of the Non-immigrant Population in European Countries

Existing studies show that there is a positive association between pro-migrant integration policies and the subjective well-being of immigrants. However, there is a lack of research elucidating the relations between migrant integration policies and the subjective well-being of the host (i.e., non-migrant) population. This study is based on European data and uses multilevel analysis to clarify the relations between migrant integration policy (both as a whole and its eight separate components such as: Labor market mobility and Family reunion) and the subjective well-being of the non-immigrant population in European countries. We examined relations between the Migrant Integration Policy Index (MIPEX) for 22 countries in Europe and subjective well-being, as assessed by the European Social Survey (ESS) data. The results demonstrated that there is a positive relation between the MIPEX and subjective well-being for non-immigrants. Considering different components of the MIPEX separately, we found most of them being positively related to the subjective well-being of non-immigrants. As no negative relationship was identified between any of the eight MIPEX components and subjective well-being, policies in favor of immigrant integration also seem to benefit the non-immigrant population.

A Typical Case Report: Internet Gaming Disorder Psychotherapy Treatment in Private Practice

Background: Online or internet gaming disorder (IGD) is currently not recognized as a mental disorder in the actual Diagnostic and Statistical Manual of Mental Disorders (DSM-5), although it is an emerging disease. Non-substance-related addictions often have similarities with substance addictions. It is therefore important to have a good understanding of the client but also to have a good endurance. Due to the rise of e-sports, there is an anticipated and therefore possible trend to have many more patients with a non-substance addiction. There are many parallels, for instance tolerance, withdrawal and social problems, resulting from an increasing investment of time spent on the internet. Case presentation: To reduce possible inhibition in treating a patient with IGD, we present a case of a 19-year-old adolescent man who exhibited IGD and showed social problems associated with his addiction. Conclusions: This paper shows the importance and the effects of treating a non-substance addiction with cognitive behavioral therapy (CBT). After having successfully coped with an addiction, several shifts in addiction were often reported. In this case, no shifts were reported. The absence of such shifts makes our case a distinct and unique case. This is not a multimorbidity case, and that is the reason why we think this is an excellent example to show what we achieved, how we achieved it, and what we could establish. Of course, additional research and manuals are urgently needed.

School alienation and academic achievement in Switzerland and Luxembourg: a longitudinal perspective

Early adolescence represents a particularly sensitive period in the life of young learners, which is accompanied by an increase in school alienation. Due to its harmful nature (Hascher and Hadjar in Educ Res 60:171-188, 2018. 10.1080/00131881.2018.1443021), school alienation may lead to unfavorable consequences such as low academic achievement (Johnson in J Educ Technol Soc 8:179-189, 2005; Reinke and Herman in Psychol Schools 39:549-559, 2002). This study investigates the longitudinal relationship between school alienation domains, namely alienation from learning, from teachers, and from classmates, and academic achievement among secondary school students of grade 7 to grade 9 in Switzerland and Luxembourg. Data were collected from 403 students in the Swiss canton of Bern and 387 students in Luxembourg who participated in three waves of the "School Alienation in Switzerland and Luxembourg (SASAL)" research project. Cross-lagged modeling was applied to examine the correlations between school alienation domains and academic achievement at each of the three time points, the temporal stability of school alienation domains and academic achievement, and their cross-lagged effects across time, controlling for students' gender, school track, parental occupational status, and migration background. Results show that the pattern of relationships is defined by the school alienation domain and the cultural context, pointing to the complex interplay between the multidimensional construct of school alienation and academic outcomes of secondary school students.
