Dann habe ich eine Ahnung, was das Bundesland angeht. Es sei denn, alle haben mittlerweile Scientologyfragebögen. So oder so, mein Glückwunsch und gut, dass eine deutsche Uni dich gewinnen konnte.

I forgot about this or missed it when reading the text. Technically, this seems correct, but besides everything else, the equal weighting of models is not plausible. Did anyone ever do this? I better not check.

This is a very useful, non-technical discussion of the multiverse analysis. Personally, I like the "Don't take it too seriously" attitude, though it is probably unsatisfying for someone who thinks about using it and wants a more definitive answers (sometimes, this is not what one gets)

New preprint! So, what's a multiverse analysis good for anyway?>

What’s a multiverse good for anyway?

Julia M. Rohrer, Jessica Hullman, and Andrew Gelman

Multiverse analysis has become a fairly popular approach, as indicated by the present special issue on the matter. Here, we take one step back and ask why one would conduct a multiverse analysis in the first place. We discuss various ways in which a multiverse may be employed – as a tool for reflection and critique, as a persuasive tool, as a serious inferential tool – as well as potential problems that arise depending on the specific purpose. For example, it fails as a persuasive tool when researchers disagree about which variations should be included in the analysis, and it fails as a serious inferential tool when the included analyses do not target a coherent estimand. Then, we take yet another step back and ask what the multiverse discourse has been good for and whether any broader lessons can be drawn. Ultimately, we conclude that the multiverse does remain a valuable tool; however, we urge against taking it too seriously.

Welcome to #OpenScience Land
expedition-open-science.org This is a lightweight, but very useful and accessible intro to key elements of Open Science (online and as a PDF). Seems particularly useful for introducing the topic to undergraduates @zbw-leibniz.bsky.social

A handdrawn of an imaginated open science land. It has as parts documentation, planning, dissemination, sea of myths and peninsula of dreams

New documents released by the Department of Justice on Friday reinforce that long after his criminal convictions, many prominent professors continued to communicate with him.

I wrote a blog for the Meta-Research Center expressing my infinite frustration about not getting data. What else is new, you might think? Well, I added an extra layer of annoyance directed at the journals who do NOTHING to enforce promised data sharing.

It is good more attention is paid to power.
In what way do we get to our senses? That more studies estimate power, or acknowledge that power is likely to be low?

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

Good point, this is plausible to me.

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

I think this is unlikely to happen, but who knows. Let's see how this plays out at Small Business Economics and how the first registered report will look like. 2/

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

Sorry, I was fully focused on the prereg part, not the reports part. Right, results-blind review would likely still work. Theoretically, if you were submitting your code with the registered report and the original data were sitting in some repo, a reviewer could quickly do the analysis. 1/

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

Not to downplay the value of the format, which is great, but these kind of studies do not open much opportunity for replications because new data would be hard to collect or it may not be possible when the original study already worked with all population-level data 3/

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

the data little insightful. It does not mean the data do not exist at the time of prereg, but there should be some credibility of the inaccessibility part.
Maybe the editors have a different view because, according to the online-first articles, most seem to work with survey, firm or country data 2/

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

I don't know, we should ask the editors what they mean to be sure. "and/or in a different context" does not read like new data to me when they refer to new data before that.
I am fine with anyone having a different read of and view on this. Personally, I find prereg with ex ante accessibility of 1/

Vielleicht kann zur Abwechslung mal jemand Niesen?

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

Thanks for the thread. From the top of my hand, it is not obvious why prereg null results should be more likely to get published. If there is a culture of positive results, prereg vs. not should do little to overturn it because transparency/credibility of the study is not relevant to peer reviewers.

Ingo Rohlfing @ingorohlfing.bsky.social · 7d

I reproduced what the editorial says because they distinguish subtypes of replications that do not all seem to involve new data, but I may misread it. My understanding of what a replication is different from the editorial's and identical to yours, but I put this aside in the original post

Few people now this but the Epstein library can be used to bypass academic journal paywalls. You search for a paper and if someone sent it to Epstein the pdf is there.

The FORRT Replication Database has received a massive overhaul (FReD 2.0): We double-coded and validated all data from scratch and extended it in the course of a one-year-partnership with the @cos.io. We just switched to a faster interface thanks to @lukaswallrich.bsky.social’s wizardry.

“Replications as Registered Reports” at Small Business Economics
link.springer.com/journal/1118...
Laudable goal, but open science and meta science may collide here. When code & data of original study are available, all replications (however defined) that do not rely on new data cannot be prereg'd

Based on your experience, you have serious concerns about this person's integrity and the integrity of the review process if this person was involved.

"[Epstein] was arrested in 2006 & pleaded guilty in 2008"

"Ariely & Epstein met at least 7 times from 2010-2016"

"Ariely is named 636 times in the more than 3 million additional files released"

"Neither Ariely nor Duke responded to ... requests for comment"

www.dukechronicle.com/article/duke...

Duke professor Dan Ariely had longstanding friendship with Jeffrey Epstein, newly released files show

Ariely is named in 636 of the some 3 million newly released files. He was a prominent professor at Duke over the course of his correspondence with Epstein.

Every time more Epstein files are released, I wonder who the "Epstein" is today because all of these billionaires and elite assholes can't have stopped abusing girls just because one guy died. Someone must have walked right in and filled that gap.
