![Roundtable Discussion: New Developments in Large-Scale Survey Data in Germany
Hybrid event [A5, 6, Room A231 + Zoom]
September 24, 2025, 13:45-15:15
Abstract
The roundtable brings together researchers from leading institutes and survey programs in Germany including the German Longitudinal Environmental Study (GLEN), the Family Research and Demographic Panel (FreDA), the Research Data Center of the Institute for Employment Research (IAB), and the Survey of Health, Aging and Retirement in Europe (SHARE). The discussion will focus on current innovations, challenges, and opportunities in large-scale survey data from the data producers’ and users’ perspective.

![Assessing the Reproducibility of Observational Social Research
Hybrid event [A5, 6, Room A231 + Zoom]
September 10, 2025, 13:45-15:15
Abstract
Reproducibility – i.e., the extent to which results are consistent when re-running the same code on the same data – is a minimum requirement for credible empirical research. However, as prior audits have tended to look at selective samples, only little is known so far about its extent in the observational social sciences. In this input talk, I present insights from a large-scale reproducibility assessment of published social science papers that use data from the European Social Survey (ESS). Starting from an initial pool of 1,206 articles, we obtained research code for 385 papers and conducted a standardized reproducibility assessment on a random sample of 100. I will present insights into our method and our results, highlight common hurdles and pitfalls we encountered, and conclude by discussing low-cost measures that could help improve reproducibility at scale.

Laura Schächtele is a PhD candidate in Sociology at the LMU Munich and part of the DFG-funded meta-scientific research program META-REP. She holds a master’s degree in Sociology from the LMU Munich and has been a visiting researcher at the Meta-Research Center at Tilburg University. In her dissertation, she investigates the links between academic incentive structures, researchers’ strategic behavior, and scientific transparency. Her broader research interests include the sociology of science, social inequality, and quantitative methods of empirical social research](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:oizrkjzyr6vekl76tjctghcl/bafkreie66sio5k5bkn7g7lhjn3dafo3eam5supiamg7jprotikx2qucgae@jpeg)
