Leibniz Open Science Day 2025: “Better Science for Better Policies”
When? 27 October 2025
Where? Berlin
Keynote: Johanna Rickne (Stockholm University)
ZBW ─ Leibniz Information Centre for Economics, DIW Berlin (the German Institute for Economic Research), WZB (Berlin Social Science Center), and RWI ─ Leibniz Institute for Economic Research are pleased to invite submissions to the Leibniz Open Science Day 2025: Better Science for Better Policies. With the growing importance of the social sciences in addressing societal challenges, the significance of a meta-scientific perspective is also increasingly on the rise. We need a deeper understanding of how evidence is generated and communicated to society and policymakers.
Replications and meta-studies in particular are becoming increasingly crucial to ensure the reliability and validity of scientific research findings. These approaches help identify heterogeneities and biases, improve methodological standards, and foster transparency, ultimately enhancing the credibility of scientific knowledge.
The workshop will take place on 27 October 2025, in Berlin (Leibniz-Association Gemeinschaft).
Limited travel assistance is available for junior researchers (doctoral students, non-tenured postdocs, and assistant professors). Please indicate in your submission whether you will require funding.
