#GDRI_rep Update 9: We have been waiting a couple of months to make two announcements. A few journals were in the process of retracting GDRI article. The editors informed the authors and then lawyers got involved. Who knows how long it will take.

Join us for the virtual Replication Games😍🤓 on Nov 13th! (You don't have to be in the UK - join us from wherever you are😉)

New DP @i4replication.bsky.social: Meta-analysis on green nudges correcting for publication bias. "Behavioral interventions on households and individuals are unlikely to deliver material climate benefits." www.econstor.eu/bitstream/10...

👏 Many thanks to everyone who took part in the Replication Games on Friday, October 3rd! 6 teams joined the challenge, 5 in person and 1 online, bringing curiosity and collaboration to every step and making this event a truly inspiring collective experience around reproducibility & open science.

Took part yesterday in @freieuniversitaet.bsky.social's Replication Games, it was such a nice experience! People were lovely and the work was a very fun challenge. Thanks to @i4replication.bsky.social and @janmarcus.de for organizing this, it was absolutely worth enduring the ride from Dortmund. 😄

🚨I4R is looking to hire postdoc fellows in public health and computer science! The postdoc will join a team of researchers and help mass reproduce studies in leading public health journals or develop AI replicator agents. Info 👇

At @i4replication.bsky.social it is our ambition to foster a replication culture in the social sciences – and we hence welcome if our approaches are replicated as well: Replication Games on using LLM in experiments, in Valencia and Oxford. talkingtomachines.org/projects/ime...

#GDRI_rep Update 8a: Major updates coming up over the next few weeks. 1st update: We reproduced "Parent–teacher meetings and student outcomes" some time ago. The paper was then retracted by the editors of the Euro Econ Rev. Additional studies are connected (see diagram) 🧵

Rejoignez nous pour une édition des Replication Games @ INRIA Paris le 3 octobre 2025 prochain ! Une journée pour répliquer des résultats scientifiques, en équipe, avec @i4replication.bsky.social 📍 INRIA Paris 🕘 9h–16h30 💸 Gratuit, inscription obligatoire #ReplicationGames #OpenScience #I4R

First up: two terms that often get mixed up 👇 🔁 Reproducibility = same data, same code 📦 Replicability = new data, same design We unpacked these (and more) with help from Brodeur et al. (2024): 📖 www.iza.org/publications... 🔥 Pro tip: join a #Replication Game via @i4replication.bsky.social

GiveWell sought an independent check on the evidence supporting >$1 billion it has granted to its top charities. This fall, Alex Cohen asked whether we could obtain the datasets needed to reproduce the underlying RCTs. We said yes; charging only a modest fee to cover our time. 🧵 + 🐀 + blog post!

It is always a pleasure, but also causes some trepidation 😰, when a bunch of motivated junior (and senior!) researchers get together at @i4replication.bsky.social replication games, and I get to observe how others work with the replication packages that we helped prepare! #Montreal

Update: We submitted the comment to the Journal of Population Economics, and today we got a desk reject with this motivation. However, we do not know their conclusion about the main results and why the paper was not retracted. Clearly, they do not hold. 1/4

Dutch academics, please share - replication games are coming to Vrije Universiteit Amsterdam on July 19! If you live in the Netherlands, or want a good reason to visit, come take a day to network, hone your skills, and potentially coauthor a paper. Registration: www.surveymonkey.ca/r/Replicatio...

Registration is open for 7 upcoming replication games: i4replication.org/games.html Looking for researchers in econ/ecology/polsci/psych/pub health San Francisco (June 19) Amsterdam (July 19) Tilburg (Aug 21) Bordeaux (Aug 24) Brno (Sept 7) Paris (Oct 3) Lyon (Oct 9) Short 🧵

I agree that such carelessness is bad. But I have also seen several cases where an IRB forbid researchers to share any data (even cleaned/anonymous) for blanket privacy reasons. That’s bad too. There is a difficult trade-off/conflict between transparency ethics and privacy ethics, needing balancing.

De-identify your data before you share it. De-identify your data before you share it. De-identify your data before you share it. De-identify your data before you share it. De-identif

Looks like one should not only validate results before publishing an article and reproduction material, but screen the material for sensitive information that should be removed #OpenScience

There is an urgent (!) need for more awareness, more skills and more solid advice on how to practice #OpenScience *responsibly* before we see more cases like this 👇🏻

We did not want to start the week like this, but here we are. Yet again our chair’s inbox is filled with messages from replicators who have opened “replication” folders only to find names, Social Insurance Numbers, mental-health diagnoses and incomes of study participants. 🧵
