Amazing chart feat. in @alphaville.ft.com Further Reading.

New blog post about the age-period-cohort identification problem!
In which, for the first time ever, I ask "What's the mechanism?" and also suggest that sometimes you may actually *not* be interested in causal inference.

…reproducibility problems are widespread. Only one in three authors (35%) share code, and even when code is available, only every second main result (51%) is numerically reproducible.
Do researchers share their code upon request? Does running their orginal code on the original data produce the original results? We provide evidence in a new Royal Society Open Science publication. Studying more than 1,000 articles which use data from the European Social Survey, we find that... 🧵
This chapter on multicollinearity is a zinger, especially the central point in Section 23.4. If your focus is on model *predictions*, multicollinearity isn't necessarily a problem, and it might even be good. Well posted, @chrisadamsecon.bsky.social!
Absolutely savage, I love it.
Well worth tuning in to!
Or perhaps this one? Sorry it's papers but sometimes it's easier long form to explain things... bsky.app/profile/oliv...
Note that this in itself is a well-replicated finding. At least a dozen studies show that when researchers replicate qualitative research, or re-analyze it, they come to basically identical themes. There is nothing special about qualitative research with respect to replicability.

Once you start thinking about implausibly large effect sizes, you can't stop spotting them around you or wondering how others aren't doing so.
Harkin et al.'s (2016) meta analysis has 740+ citations, but it reports Cohen d values as large as 14. 17 cases of d>4.

Our new paper, with colleagues from the Strategic Council of the National Academies, offers an integrative framework of the several components that contribute to making research findings trustworthy including ethics, methodology, transparency, inclusion, assessment, etc

🧵 New WP with @kaimiele.bsky.social. We document 2 unsettling patterns in mental health care: 1) despite universal coverage, few individuals with mental illness receive guideline-consistent treatment, and 2) the more severe the illness, the lower the treatment uptake & the longer the wait times. 1/n
This is a very cool study and, as far as I can tell from a quick read, robust.
Statins probably don't cause most of the side-effects that people think they do.

"The verifiability of mathematical (or statistical) claims makes math a justifiably popular means for communication between researchers."
The state of mental health care in Germany has been a huge discussion issue in my circles and these findings are fascinating but also concerning -- expanded capacity does not automatically reach those most in need.

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.

I have stopped my thread at 20 for now. Thanks to all who contributed. The focus is on academics who sought promotion by, accepted money from, maintained direct interaction with Jeffrey Epstein well after his 2008 conviction.

Brilliant analysis. The first aggregate evidence I've seen that PubPeer is performing institutions' research integrity oversight function for them.
"you could - by careful choice of an existing scoring method from the literature - find any effect, or nothing, or the reverse of any effect you choose. This is bonkers. ... so extreme as to be farcical."
This is the sentiment we were hoping people would come away with!
