Abstract

This paper reports findings from a crowdsourced replication. Eighty-five independent teams attempted a computational replication of results reported in an original study of policy preferences and immigration by fitting the same statistical models to the same data. The replication involved an experimental condition. Random assignment put participating teams into either the transparent group that received the original study and code, or the opaque group receiving only a methods section, rough results description and no code. The transparent group mostly verified the numerical results of the original study with the same sign and p-value threshold (95.7%), while the opaque group had less success (89.3%). Exact numerical reproductions to the second decimal place were far less common (76.9% and 48.1%), and the number of teams who verified at least 95% of all effects in all models they ran was 79.5% and 65.2% respectively. Therefore, the reliability we quantify depends on how reliability is defined, but most definitions suggest it would take a minimum of three independent replications to achieve reliability. Qualitative investigation of the teams’ workflows reveals many causes of error including mistakes and procedural variations. Although minor error across researchers is not surprising, we show this occurs where it is least expected in the case of computational reproduction. Even when we curate the results to boost ecological validity, the error remains large enough to undermine reliability between researchers to some extent. The presence of inter-researcher variability may explain some of the current “reliability crisis” in the social sciences because it may be undetected in all forms of research involving data analysis. The obvious implication of our study is more transparency. Broader implications are that researcher variability adds an additional meta-source of error that may not derive from conscious measurement or modeling decisions, and that replications cannot alone resolve this type of uncertainty.

3. Abgehängt, fremdenfeindlich, oder einfach nur unzufrieden?

Author

Manuel Kleinert

Abstract

Die AfD und ihre Wahlerschaft sind in den letzten Jahren zu einem popularen Forschungsfeld der Wahl- und Einstellungsforschung geworden. Bisherige Studien beziehen sich dabei oft auf drei unterschiedliche theoretische Ansatze: a) okonomische Deprivation, b) fremdenfeindliche Einstellungen und c) politische Unzufriedenheit. Oftmals stehen diese jedoch unverbunden nebeneinander oder werden nur in ihrer Erklarungskraft miteinander verglichen. Das Ziel dieses Beitrages besteht darin, aus einer theorieintegrierenden Perspektive diese ausgewahlten Erklarungsansatze systematisch miteinander zu verknupfen und empirisch zu uberprufen. Dieses Vorgehen ermoglicht ein besonders umfassendes Verstandnis der individuellen Ursachen fur Sympathie mit der AfD, das neben direkten auch indirekte und moderierende Einflusse spezifiziert. Die Ergebnisse von mehreren Datensatzen zeigen, dass sich okonomische Deprivation nur in geringem Mase auf die Sympathie fur die AfD auswirkt, wohl aber xenophobe Einstellungen verstarkt, die sich wiederum stark auf die AfD-Sympathie auswirken. Politische Unzufriedenheit ist dabei ein wichtiger Moderator dieser Beziehung. Auserdem zeigt sich, dass die Methode der Theorieintegration eine wertvolle Erganzung zum parallelen Theorienvergleich sein kann.

Abstract

In an era of mass migration, social scientists, populist parties and social movements raise concerns over the future of immigration-destination societies. What impacts does this have on policy and social solidarity? Comparative cross-national research, relying mostly on secondary data, has findings in different directions. There is a threat of selective model reporting and lack of replicability. The heterogeneity of countries obscures attempts to clearly define data-generating models. P-hacking and HARKing lurk among standard research practices in this area.This project employs crowdsourcing to address these issues. It draws on replication, deliberation, meta-analysis and harnessing the power of many minds at once. The Crowdsourced Replication Initiative carries two main goals, (a) to better investigate the linkage between immigration and social policy preferences across countries, and (b) to develop crowdsourcing as a social science method. The Executive Report provides short reviews of the area of social policy preferences and immigration, and the methods and impetus behind crowdsourcing plus a description of the entire project. Three main areas of findings will appear in three papers, that are registered as PAPs or in process.
