Right 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.

Episode 2 from our 1-day I4R workshop is out. @janmarcus.de, @josefinaw.bsky.social & René Bekkers ask: How can we link publications to replications, so anyone reading a paper can instantly see whether its findings have been retested? 🧵

📢 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.

There’s been a lot of buzz around the Borjas/Breznau (2026) paper (www.science.org/doi/10.1126/...) and potential ideological bias in research. We took a closer look at the data. Could there be a "bias in bias research"? Here is what we found: www.econstor.eu/bitstream/10...
