Reposted by Jan MarcusInstitute for Replication @i4replication.bsky.social · 24/09/2026Right now, a replication can exist and still be almost invisible to someone reading the original paper. That makes it harder for researchers, reviewers, students, journalists, and policymakers to know what evidence has accumulated around a finding. 111

Jan Marcus @janmarcus.de · 04/09/2026The takeaway: randomizing question order can help reduce cheating without hurting students’ overall performance. 131
Jan Marcus @janmarcus.de · 04/09/2026@mcempirics.bsky.social is an e-learning platform developed by my co-author #ThomasSiedler, primarily for economics students and lecturers. The data allow us to study question-order effects in real-world assessments at an unusually large scale. 100
Jan Marcus @janmarcus.de · 04/09/2026We use a unique dataset from @mcempirics.bsky.social covering 8,000+ online tests and exams, 45 randomized field experiments, and students in economics, econometrics, and statistics at two large German universities. 110
Jan Marcus @janmarcus.de · 04/09/2026📢 New paper out in the #JournalofHumanCapital with #AgataGalkiewicz and #ThomasSiedler Can starting an exam with a difficult question hurt students’ performance? We find no evidence that it does — even in incentivized assessments under time pressure. 1134

Jan Marcus @janmarcus.de · 24/07/2026If you have a replication study or a substantive comment on published research, we'd be delighted to receive your submission. 110
Jan Marcus @janmarcus.de · 24/07/2026That additional effort is well worth it. Replications are a cornerstone of scientific progress, yet there have long been too few dedicated publication outlets for them. That's one of the main reasons I was happy to join @jcre.bsky.social as a Co-Editor. 100
Jan Marcus @janmarcus.de · 24/07/2026Replication studies typically require considerably more work during peer review than standard submissions. Editors and reviewers often need to read not only the replication, but also the original paper, and there may be exchange between the replicating and original authors. 110
Jan Marcus @janmarcus.de · 24/07/2026Many thanks to the authors, the referees, and the @jcre.bsky.social editorial staff @zbw-leibniz.bsky.social for making this possible in a remarkably short time from submission to publication. It was a pleasure working with everyone involved. 120
Jan Marcus @janmarcus.de · 24/07/2026This year I joined the editorial team of @jcre.bsky.social, the Journal of Comments and Replications in Economics (JCRE) as a Co-Editor.
