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 🧵

🚨 REPLICATION REPORT UPDATE: One year ago, a tweet by John Holbein alerted me, @ollefolke.bsky.social, and @jopieboy.bsky.social to a paper with a shocking result about Sweden’s law criminalizing the purchase of sex.🧵

American chopper meme. Two men are yelling at each other. YOU SHOULD REPORT THE MARGINAL EFFECTS. I REPORTED THE COEFFICIENT VALUES. WHAT MORE DO YOU WANT? PEOPLE HAVE A HARD TIME INTERPRETING THOSE VALUES. MINUS MEANS LESS AND PLUS MEANS MORE. THAT'S GOOD ENOUGH! INTERPRETING EFFECTS ON THE SCALE OF INTEREST IS NATURAL AND BENEFICIAL.

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) 🙌

Our proposal for protocolled replicability & robustness assessments is out in Q Open. The main aim is to structure robustness reproductions, but also to extend the scope to external/construct validity as well as pre-specification checks. Comments welcome! academic.oup.com/qopen/advanc...

Do men increase their support for gender equality if they have daughters?

Some papers suggest so!

Join this meta-science project as a co-author, work with SOEP data and help us all learn more!

🔔 Call for Participation 🔔
Lab² is inviting researchers to take part in a multi-analyst study on the effects of having daughters on various outcomes.
Join this metascience project as a co-author and gain the opportunity to work with SOEP data!

Collaborators are looking for participants for a new multi-analyst study using SOEP data. For more information on registration, eligibility criteria, requirements, procedure, and timeline, please visit www.manydaughters.com. Deadline for registration is April 27

#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 🧵

When One Size Doesn’t Fit All Many psychological scientists are now calling for a “heterogeneity revolution,” focused on uncovering individual and contextual differences in experimental outcomes.

Many psychological scientists are now calling for a “heterogeneity revolution,” focused on uncovering individual and contextual differences in experimental outcomes.

#GDRI_rep Update 5: We have a new report. We reproduced the paper entitled "Partisan Effects of Information Campaigns in Competitive Authoritarian Elections: Evidence from Bangladesh" by Ahmed, Hodler and Islam published at the Economic Journal. See below for links to report and authors' responses.

Since we started mass reproducing GDRI, we have requested several replication packages. We have not managed to get a single new replication package as of today (excluding updated packages for one article at the request of editors).

In a new @i4replication.bsky.social report we replicate Islam (2019). Main issue: the randomized controlled trial was not randomized. And many other things on top of that. See full report for details. (w/ @carlbonander.bsky.social, @nikljako.bsky.social, @flxhlzmstr.bsky.social, Bensch & Brodeur)

#GDRI_rep Update 4: We have a new report. We reproduced the paper entitled "Parent–teacher meetings and student outcomes" by Islam @ European Economic Review. See below for links to report and author's response.

#GDRI_rep Update 3: The paper "Improving Hygiene and Sanitation through Parental Skill Training" by Asadul Islam, Umair Khalil and Tabassum Rahman was conditionally accepted at Economic Development and Cultural Change. We requested a replication package. It has now been withdrawn

#GDRI_rep Update 1: I4R are now reproducing all published papers that use data from GDRI, or are closely related in other ways. Here is a first update on our work. 🧵

After a long wait, the working paper for the Many-Economists Project: The Sources of Researcher Variation in Economics. We had 146 teams perform the same research three times, each time with less freedom. What source of freedom leads to different choices and results? papers.ssrn.com/sol3/papers....

I4R doing the lord’s work. Hopefully these will be a collective wake up call to be more careful and transparent about complicated studies in applied micro (and elsewhere too)

Disregarding the sadness of this story, it’s been great working with this awesome team! @jrgptrs.bsky.social @fialalenka.bsky.social @jackfitzgerald.bsky.social @flxhlzmstr.bsky.social @nikljako.bsky.social @anderskjelsrud.bsky.social @kotsadam.bsky.social @essieconomist.bsky.social

As a coauthor on the AEJ:AE report, it’s a lot. Oh my god, It’s a lot. In that paper, outcomes are inconsistently handled both in the code and in the field, the paper’s data is connected to a bunch of other experiments, and we find irregularities in the raw survey files.

The MOOB that I host (massive open online bibliography) for #openscience and #metascience literature is approaching 2,000 articles. You can freely have it via @zotero.org

After being alerted about possible misconduct, the I4R are reproducing published papers that use data from a specific NGO (GDRI). This thread releases the first 2 reports and provides more information about the work and responses/statements from authors journals and journals. 🧵

This is based on our work. We will provide more information on Monday. Stay tuned and thanks Ray and Will for your help!

Sunday 9PM ET / Monday 3AM CET / Monday 1PM Melbourne! See you all then :)

Abel: I am writing in my capacity as Chair of I4R. Last year, I was contacted by a researcher that alerted me of potential scientific misconduct in a set of papers all using data from a specific NGO.🧵
