This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions problems in science focus on systematic biases. We broaden lens to emphasize idiosyncrasy conscious and unconscious decisions that researchers make during data analysis. coordinated 161 73 research teams observed their as they used same independently test prominent social hypothesis: greater immigration reduces support for policies among public.

This study investigates researcher variability in computational reproduction, an activity for which it is least expected. Eighty-five independent teams attempted numerical replication of results from original policy preferences and immigration. Reproduction were randomly grouped into a ‘transparent group’ receiving code or ‘opaque only method description no code. The transparent group mostly verified (95.7% same sign p -value cutoff), while the opaque had less success (89.3%). Second-decimal...
Involuntarily or planned – many refugees flee their home country alone, leave behind spouses and children but also siblings, parents other family members they otherwise care for. Reunification in hosting communities is difficult, as governments limit institutional reunifications the individual journey of kin dangerous often illegal. Having abroad mentally distressing for refugees, might not live safety. Additionally, reuniting with can be a source support new environment. Grounded theories...
Over the course of 2013 to 2016, over one million asylum seekers arrived in Germany, around 890,000 them 2015 alone. The growing refugee population posed a major challenge for Germany’s policy makers, civic administrators, and society at large, finding new approaches registration procedures, housing, social economic integration. To design policies programs that meet these needs, government politicians, public require robust analyses accompanying demographic changes based on timely, valid,...

Abstract This study introduces and investigates the validity of a brief scale measuring challenged sense belonging. The belonging as well challenges to this are important, albeit neglected aspects social integration significance migration refugee studies virtually all other science contexts. Assessing or eroded provides important insights into how individuals relate their environment whether they feel socially connected disconnected from it. construct goes beyond national cultural identity,...
Background The integration of artificial intelligence (AI) holds substantial potential to alter diagnostics and treatment in health care settings. However, public attitudes toward AI, including trust risk perception, are key its ethical effective adoption. Despite growing interest, empirical research on the factors shaping support for AI (particularly large-scale, representative contexts) remains limited. Objective This study aimed investigate patient care, focusing how attributes (autonomy,...

About 80 million people were displaced worldwide at the end of 2020. To support this highly vulnerable group, in recent years, local bottom-up initiatives proliferated to refugee integration hosting communities. This study examines a network intervention for refugees collaboration with social start-up whose mission is match and volunteers form friendships. We apply an innovative randomised controlled trial approach 446 participants integrated into survey almost 8000 randomly sampled who...
Abstract This study addresses the heated academic and public debate on compatibility comparability of refugees’ host societies’ democratic values. Comparative values research has long capitalized global similarities differences in support for Western We argue that such cross-cultural comparisons culturally diverse groups are challenged by (1) different conceptions democracy determined experiences with systems (2) bias introduced linguistic translation processes. In order to analyze whether...
Geflüchtete aus der Ukraine wurden direkt nach Beginn des russischen Angriffskrieges Ende Februar 2022 in vielen europäischen Ländern mit überwältigender Solidarität empfangen, auch Deutschland. Hat sich die Haltung Menschen seitdem verändert? In diesem DeZIM.insights Working Paper analysieren wir Unterstützungsbereitschaft im ersten Jahr Kriegsbeginn.Hierzu greifen auf Daten DeZIM.panels zurück und untersuchen, wie den Bereichen freiwilliges Engagement, Spendenbereitschaft sowie...
Abstract With the so-called ‘long summer of migration’ 2015, there was an urgent need to accommodate many refugees in Germany. This situation framed as a ‘refugee reception crisis’, and it revealed diametrically opposed stances within German society. Within this debate, anti-refugee sentiment is often explained with placement nearby refugee facilities. Conclusive evidence claim yet missing. Most studies dealing immigration attitudes toward lack appropriate geo-data test assumption. We fill...
Was wird erklärt? Sozialwissenschaftliche Untersuchungen basieren häufig auf Umfragen. Gelten diese als repräsentativ, so ist dies ein Gütesiegel für die Möglichkeit, Aussagen über eine Grundgesamtheit zu treffen. genau bedeutet aber "repräsentativ" – und welche Umfragen können bezeichnet werden?

A social structural explanation considers individual resources crucial for argues that a redistribution those may bring about changes in engagement. cohort-based socialisation experiences formative years as the uptake Finally, period-based extraordinary events, external shocks, crises to be So far, these have mainly been tested separately little is known...

The 2012 Federal Act Recognition in Germany is a new institution that provides possibility study depth. I argue analysing decision for recognition credentials an important aspect because it mirrors investment future labour-market access. hypothesize institutions, such as and language classes refugee...
Panel attrition poses major threats to the survey quality of panel studies. Many features have been introduced keep as low possible. Based on a random sample refugees, highly mobile population, we investigate whether using phone application improves address and response behavior. Various features, including geo-tracking, collecting email addresses adress changes, are tested. Additionally, respondent interviewer effects consent download app sharing GPS geo-positions. Our findings show that...

In an era of mass migration, social scientists, populist parties and movements raise concerns over the future immigration-destination societies. What impacts does this have on policy solidarity? Comparative cross-national research, relying mostly secondary data, has findings in different directions. There is a threat selective model reporting lack replicability. The heterogeneity countries obscures attempts to clearly define data-generating models. P-hacking HARKing lurk among standard...
Abstract This article highlights the potentials for migration research using German Socio-Economic Panel Study (SOEP), a longitudinal panel dataset of private households in Germany running since 1984. We provide concise overview its basic features, describe survey contents and potentials, demonstrate opportunities to link external data sources SOEP thereby presenting diverse impactful applications research.
