University librarian made my Monday: [I am getting an econometrics textbook] "Do you know that we have non-academic books too? From the theology collection we have Monty Python."😆

#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.

So many interesting folks at the #NOSF2025 in Groningen🤩 Great to see people interested in open science😊

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😉)

There is still time to apply, join us! #econsky

We are hiring! Join a strong team to have a real impact on how science is done😊 #econsky

🚨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 👇

Come joun us in Münster, it will be awesome😉😎

I4R Replication Games coming to Münster! @i4replication.bsky.social @aufdroeseler.bsky.social @fialalenka.bsky.social

1/ The Vertical & Horizontal AI Replication Games debut at the University of Ottawa on Oct 16! This is the first event feeding into our next paper, and all participants will be listed as coauthors. Apply: www.surveymonkey.ca/r/TKRS5HG

The Brno Replication Games were a success!🥳 Many thanks to our awesome replicators who spotted a range of coding errors and fixed incorrectly specified models. Many thanks also to @econmuni.bsky.social for having us: you are the reason economists love coming back every year😊

Off to the #BrnoReplicationGames at @econmuni.bsky.social, it's going to be epic!

🚨 We have a comment on Begum et al (2018) forthcoming in @readdemography.bsky.social - see link below! @i4replication.bsky.social

#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) 🧵

Only a one week left left to register to the Brno Replication Games on Sept 7th. Virtual participation is possible and coauthorship to a meta paper is granted. Register here: www.surveymonkey.ca/r/Replicatio...

Cool event reminder! Please note we now have a number of €200 awards for PhD students travelling to Galway to participate. If you wish to be considered for an award, please get in touch (contact details at end of Matthew’s thread). Reposts welcome! Cc: @i4replication.bsky.social

The Tilburg Replication Games were a success! Many thanks to the replicators for making it a great event. 😊

ESA econ folks, join us! It's going to be a ton of fun, Brno always delivers :)

There have been a number of recent articles on statistical power in quantitative political science. This is something that I think deserves more attention and discussion. A short thread of the articles I have read. 🧵

Final call for the Tilburg Replication Games! Are you a social scientist who is interested in replicability/reproducibility, and open science? Do you want to contribute to a large-scale meta analysis and become a co-author? Then sign up today! Online and in-person participation are possible.

Come join us in Tilburg! #reproducibility #openscience #econsky

So Science retracted the arsenic life paper because it was wrong? If that's the new standard for retraction, I think they've got a lot of work ahead of them

We have 8 replication games over the next 13 weeks (Tilburg, Bordeaux, Brno, Galway, Berlin, Paris, Lyon and Ottawa)! Not too late to register to any of these events: i4replication.org/games.html

;)

Replication Games in Amsterdam today! We will have 8 teams replicating papers from top social science journals. Many thanks to @jackfitzgerald.bsky.social, our local organizer. #I4R

Only a few days left to register to the Amsterdam Replication Games on July 19. Virtual participation is possible and coauthorship to a meta paper is granted. Register: www.surveymonkey.ca/r/Replicatio...

Come join us in Amsterdam, it's going to be awesome!

Join us @rwi.bsky.social & @i4replication.bsky.social as replicator for a meta-reproduction on deforestation. We pay replicators 2,500 EUR. Experience with geocoded data & background in environmental science are assets. 1/2 bit.ly/4ke2p6o

I really recommend this podcast episode on the story of this paper and the strange non-responses from the journal. A depressing case of how science fails to be self-correcting even in the face of extremely obvious errors. open.spotify.com/episode/4Eo0...

Here’s a New York Times photo of the Chicago “No Kings” rally. NYT said the march that followed spanned at least 10 blocks.

Christ's sake, Chicago, I'm just trying to go for a walk.

Thanks for the great comments, #CEA😊🇨🇦

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!

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. 🧵

"I believe we are in crisis. The distance between what is said and what is known to be true has become an abyss. Of all the things at risk, the loss of an objective reality is perhaps the most dangerous. The death of truth is the ultimate victory of evil. When the truth leaves us, when we let it

A re-analysis of Ciacci's (2024) "Banning the purchase of sex increases cases of rape: Evidence from Sweden" Journal of Population Economics reveals major issues. A year ago, reproducers Adema, Folke, and Rickne found coding errors driving the paper's key results. Let's unpack this in a 🧵

The AI knew enough to give him a red lightsaber is all I'm saying.

“Among articles stating that data was available upon request, only 17% shared data upon request.”

We are pleased to announce an experiment intended to stimulate academic discussion and exchange, centered on papers published in Econometrica 1/5

A Bangladesh-based organization focused on development economics and its founder have been churning out papers filled with misstatements, inconsistencies, ethical lapses and “statistically improbable data,” according to researchers involved in an ongoing effort to replicate the work.

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.

Great to see our comment now available online in the European Economic Review! (w/ @carlbonander.bsky.social, @nikljako.bsky.social, @flxhlzmstr.bsky.social, Gunther Bensch & Abel Brodeur @i4replication.bsky.social) 🙌

#GDRI_rep Update 7: Retraction! Our comment of "Parent–teacher meetings and student outcomes: Evidence from a developing country" has led to the paper being retracted. Our comment is accepted as is. Short 🧵
