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.

A growing body of research connects diversity to anti-welfare attitudes and lower levels social welfare expenditure, yet most evidence comes from analyses US states or comparisons the United States Europe. Comparative European nation-states, however, yield little that immigration – measured at country-level reduces support for national state programs. This is not surprising, given suggests impact occurs smaller, sub-national geographic units. Therefore, in this article, we test hypothesis...
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...
Nate Breznau Sociological Science, August 17, 2015 DOI 10.15195/v2.a20 Abstract This article reports the results of a replication Brooks and Manza's Social Policy Responsiveness in Developed Democracies published 2006 American Review.
Welfare policies are a common feature of many societies and often strongly favored by the public. Research abounds on welfare policy differences across nations yet scholars pay less attention to why how public formulate opinions policies. The following analysis shows evidence that not merely self-interested in their preferences. I propose instead they have further goal mind unrelated material gains: reduction social inequality. investigate this possibility using survey data from large,...
The intersection of group dynamics and socioeconomic status theories is applied as a framework for the puzzling relationship immigration support welfare state in Western Europe. Group suggest that how individuals define their boundaries moderates impact on state. Immigrant presence should have strongest effects those with exclusive national boundaries; weaker conditionally inclusive based reciprocity; weakest or non-existent boundaries. interact material self-interest, leading less security...
The Novel Coronavirus Pandemic causes heightened risk perceptions, in particular related to health, mortality and economic security. In 'normal' times, these are risks covered by social welfare states via insurance protection policies. My research question is what role the state plays a global emergency - here SARS-Cov-2 pandemic. I test for an impact of on perceptions using COVIDiSTRESS data comparing 70 countries April, 2020. Adjusting local timing severity outbreak, demonstrate that...
Reliability, transparency, and ethical crises pushed many social science disciplines toward dramatic changes, in particular psychology more recently political science. This paper discusses why sociology should also change. It reviews as a discipline through the lens of current practices, definitions sociology, positions sociological associations, brief consideration arguments three highly influential yet epistemologically diverse sociologists: Weber, Merton, Habermas. is general overview for...

Abstract This paper pushes forward political research from across disciplines seeking to understand the linkages between public opinion and social policy in democracies. It considers thermostatic increasing returns perspectives as pointing toward a potentially stable set of effects running policy. Both theoretical argue that are reciprocally causal, feeding back on one another. is general argument found opinion‐policy literatures. However, much empirical claims model “feedback” when actually...
Multiverse analysis has emerged as a valuable tool for increasing transparency and assessing robustness in empirical research across many scientific disciplines. By systematically exploring multiple defensible analytical paths, researchers can uncover how different decisions data processing, model specification, estimation impact results. However, while multiverse holds significant promise, it also presents several challenges that must navigate. This paper draws on interdisciplinary...
A general overview of artificial intelligence (AI) designed for academic students, workers, researchers and teachers. It is a less technical introduction those us who are not familiar with computer science. focuses primarily on generative AI (Gen AI) as this the tool that rapidly transforming every aspect work. This primer covers four areas: 1. How does know what it knows? – An neural networks, large language models “knowledge” in Gen AI; 2. Ethics Best Practices Good scientific practice,...
Huntington claimed that today's major conflicts are most likely to erupt between religiously defined "civilizations," in particular Christianity and Islam. Using World Values Surveys from 86 nations, we examine differences Christians Muslims preferences for religious political leaders. The results suggest a marked difference their attitudes toward politicians, with more favorable by 20 points out of 100. Devoutness, education, degree government corruption, status as formerly Communist state...
We provide an overview of the field preferences for redistribution research, including divergent terminological and theoretical approaches. review different uses public attitudes, policy opinion. outline roles material interests, values opinion-policy endogeneity. also introduce summarize original research presented in this Special Issue. Among key contributions Issue to subfield are novel explorations how socialization affects redistribution; examination perceptions about inequality...
In this paper, I extend the concept of observer effect into realm country-level secondary data analysis. When analyzing what appear to be same using methods, macro-comparative researchers arrive at different results. argue that is a product idiosyncratic variation directly or indirectly produced by researchers. Even when bias produces only small perturbations in results, consequences may very large. Using an influential study Brooks and Manza analyze (SOE). Two seemingly identical...
Abstract Does public opinion react to inequality, and if so, how? The social harms caused by increasing inequality should cause ramp up demand for welfare protections. However, the may differently depending on institutional context. Using ISSP WID data (1980‒2006), we tested these claims. In liberal contexts (mostly English‐speaking), income predicted higher support state provision of welfare. coordinated universalist Europe), less support. Historically concentration support, providing an...
The following mixed method study investigates Michigan’s system of fiscal emergency management, which disproportionately impacts African Americans. According to conventional explanations, the overrepresentation political intervention (EPI) in black communities is a happenstance product American populations being concentrated fiscally distressed urban areas. We first investigate this hypothetically spurious association using multivariate methods. While State’s objective scoring local units...
The emergence of large-scale replication projects yielding successful rates substantially lower than expected caused the behavioural, cognitive, and social sciences to experience a so-called ‘replication crisis’. In this Perspective, we reframe ‘crisis’ through lens credibility revolution, focusing on positive structural, procedural community-driven changes. Second, outline path expand ongoing advances improvements. revolution has been an impetus several substantive changes which will have...
We uncover how the “hidden uncertainty" seen in multi-analyst studies can be tackled using bestpractices global sensitivity analysis (GSA). GSA allows discovery of where missing outputuncertainty is located and why it has escaped previous analyses. superior to existingmultiverse that (i) uses state art sampling strategies explore space themodelling options – so-called garden forking paths (ii) reveals no single variablein isolation responsible for a sizeable fraction output variance, which...

When analyzing what appear be same utilizing methods, macro-comparative researchers arrive at different results. argue that is a product idiosyncratic variation directly or indirectly produced by researcher. Even when bias produces only small perturbations in interpretation results, consequences may large for small-N analyses. Using an influential study Brooks and Manza analyze effect.
